Gmail could soon help you skim your entire inbox without opening any emails (APK teardown)
Edgar Cervantes / Android Authority
TL;DR Gmail is working on a new feature that could display a one-line AI summary directly in your inbox in the main email list.
Such brief, auto-updating synopses could help you quickly scan long conversations without opening them.
When the feature rolls out, users will also be able to provide feedback on the one-line summaries with 'Helpful' or 'Not Helpful' votes.
One of the most common use cases for AI is using it for summarizing content. AI summaries are really helpful in condensing information from long threads for skimming through, and you can always read through the whole conversation if you need more details. Gmail implemented automatic Gemini summary cards in the Android app late last month, and it seems the service could expand these summaries into the main email list too.

An APK teardown helps predict features that may arrive on a service in the future based on work-in-progress code. However, it is possible that such predicted features may not make it to a public release.
Gmail users can trigger AI-based summaries in several ways. They can manually trigger an email summary on any email by clicking the 'Summarize this email' button at the top of the message. This will open Gemini and show a summary of the thread. Gmail also automatically creates AI summaries on long email threads or messages with several replies — the summary also keeps up to date with any new replies.
However, both of these options require users to be in a specific email thread, which makes skimming through messages less efficient.
Gmail v2025.06.22 includes code for enabling email summary cards right out in the main email list. These appear to be a super-condensed one-line summary of the entire email thread. We managed to activate the feature ahead of its release to give you an early look:
As you can see in the first screenshot, the first email has a one-liner email summary visible. Other email threads aren't as long, so they don't need a summary in the main email list per se. Even with just one summarized email, coupled with other summary cards like for orders (see the Shiprocket 'Expected' and 'Delivered' summary in the first screenshot), you can see how the main email list becomes skimmable, letting you go through one full screen of emails and figure out what you need to action.
Naturally, there's only so much information that a one-liner summary can provide, so you can't rely on it to completely tell you all the details on all long threads. Still, it would be a convenient way to have up-to-date information displayed in the main email list.
As you can see in the third screenshot, you can long-press on emails with one-liner summaries and tap on the three-dot menu to get the 'Helpful summary' and 'Not a helpful summary' voting options.
Google has yet to announce this change for Gmail. Given its utility in taming wild inboxes, we hope to see it roll out soon.

The Cyber Risk SMBs Can't Afford To Ignore
AI-driven threats are rewriting the rulebook. Here's the new cybersecurity playbook every small business must adopt before it's too late June just marked National Cybersecurity Education Month, an effort to raise awareness and expand the cybersecurity workforce. While public understanding is growing, so is the scale and sophistication of attacks. In the age of AI, threats no longer target only governments and large organizations. Cyberattacks now strike in unexpected places, putting individuals, SMBs, and entire systems at risk. Awareness alone isn't enough. Are we prepared? A recent conference held at Nasdaq by the Digital Evolution Institute explored the digital fabric comprising AI, data, and cybersecurity, and put a fascinating spotlight on the growing and unexpected risks and consequences. Byron Loflin, Nasdaq Board Excellence Center at the conference Digital Evolution Institute founder Julia Valentine stressed throughout the conference the shift from cyber crises as technical incidents to business and leadership-level challenges, and explained why being proactive in cyber crisis preparedness is no longer a luxury but a must-have. Cyber risk is a business risk Valentine, Presidential Lifetime Achievement Award recipient, entrepreneur, and a long time investor, is also the founder of AlphaMille, a global technology consulting firm specializing in digital and physical security, stressed at the conference that 'Companies cannot look to the government to protect them from cyberattacks in the AI era. Digital exposure should be treated as any other initiative that creates revenue, reduces cost, and mitigates risk,' she said, offering a familiar example from 2021, when R.R. Donnelley & Sons (RRD), a global provider of business communication and marketing services, which went through a ransomware attack that exposed sensitive client data. In 2024, the SEC reached a $2.125 million settlement with RRD for violating the internal controls and disclosure controls provisions of federal securities laws. As part of remediation, RRD revised incident response policies and procedures, adopted new cybersecurity technology and controls, updated employee training, and increased cybersecurity personnel headcount - all basic cybersecurity measures that shareholders increasingly expect to be put in place as a normal course of business. 'The 'R.R. Donnelley' case was a wake-up call,' Valentine now says. 'Despite being a data-intensive company, they missed key warning signs. This cost them millions and damaged client trust. Overlooking cybersecurity doesn't just increase risk; it sets a company up for sudden and devastating failure.' Presidential Lifetime Achievement Award recipient, entrepreneur, and a long time investor, Julia ... More Valentine at the conference. While awareness is supposedly on the rise, cybercrime losses have been steadily increasing, and projections indicate a continued upward trend. Globally, cybercrime costs are projected to reach $10.5 trillion annually by 2025, according to Cybersecurity Ventures. The annual cost of cybercrime in the U.S. alone is estimated to be around $639 billion in 2025. According to Valentine, three things need to happen to change the trend: 'Cybersecurity needs to be elevated to the board level. The board needs to calibrate the right amount of information it needs for effective oversight, and the company needs to right-size its cybersecurity defenses.' During the conference, broad discussions by key industry leaders explored this shift in priorities from multiple angles. 'As fiduciaries, we are now responsible for the resilience of our organizations, not just our balance sheets.' From a management and board perspective, it was made clear that the change starts there: 'Cybersecurity must be viewed not as an IT expense, but as a strategic differentiator. Boards need fluency in incident response, third-party risk, threat intelligence, and yes, a solid recovery plan. Because a breach today is no longer just a technical failure, it's a governance failure.' SMBs Are Losing the Battle to Cybercrime In today's digital economy, small and midsize businesses (SMBs) are no longer flying under the radar of cybercriminals. In fact, they've become prime targets. According to recent industry reports, nearly 60% of SMBs experience a cyberattack each year. 'Many SMBs operate under the dangerous assumption that they're too small or insignificant to attract cybercriminals,' she says. 'In reality, attackers often see SMBs as low-hanging fruit, companies with valuable data but weaker defenses. Whether it's financial records, employee data, or client information, your business is a digital goldmine to hackers.' Many small businesses are at serious risk without realizing it. Common signs include not using multi-factor authentication, not knowing what systems or tools are in use, and ignoring alerts or phishing emails. Relying on basic IT support, skipping regular backups, running outdated software, and lacking a clear response plan all leave the door open to attacks. Even being denied cyber insurance can be a red flag. So beyond misconceptions, what's actually preventing SMBs from getting the protection they need? Valentine outlines five practical barriers that prevent SMBs from getting the cybersecurity protection they need: Cyber protection is not out of reach. SMBs need focused, outsourced, and staged solutions, not bloated enterprise packages. "SMBs must treat cybersecurity like a business imperative." With the different views discussed at the conference, a new 'playbook' was created with the critical steps each business, big and small, must take. Valentine is now outlining The New Cybersecurity Playbook for SMBs: 7 Essential Steps: 'Cybersecurity is a boardroom concern and a business imperative,' she concludes. 'A modern, tested cyber playbook is the best line of defense.'

The best knife sharpeners in 2025, tested and reviewed
The best knife sharpener we tested Best knife sharpener: Presto 08810 Professional EverSharp Knife Sharpener Even the best kitchen knife set in your home will eventually need its blades sharpened, and that's when you'll want to have the best knife sharpener on hand, especially if you're a home cook who chops and slices often. A kitchen knife is one of the most crucial cookware products in a kitchen, and not only is preparing vegetables and meats much easier if you have a sharp knife — along with a reliable cutting board and a complete cookware set — but it's safer too. With this in mind, I conducted an in-depth product test on five knife sharpeners of different sizes and weights to find out which one could sharpen my kitchen knives best. After sharpening various dull blades and slicing countless tomatoes, avocados, bell peppers and strawberries, I found a knife sharpener from Presto at a great price that's perfect for anyone's kitchen. Presto 08810 Professional EverSharp Knife Sharpener Thanks to its intuitive, simple design and great performance, the Presto 08810 Professional EverSharp Knife Sharpener was a no-brainer as the top pick in testing. It offers three grinding wheels that can quickly sharpen and polish thick, medium and thin knife blades. Reasonably priced at under $80, it's also a great value on a much-needed kitchen item. The Presto 08810 Professional EverSharp Knife Sharpener is a 'three-stage sharpening system' that can sharpen alloy steel, carbon steel or stainless steel knives, including kitchen knives and most sporting knives. Effective and easy to use, this sharpener turned a dull blade that could hardly break the skin of a tomato or avocado to a beast that can easily slice through mounds of tomatoes and avocados, and even bell peppers and strawberries, with lightning speed. The Presto knife sharpener offers three graduated grinding wheels and a blade selector dial. The first stage of sharpening uses the rough wheel, located on the left, and is meant for coarse grinding. Next, you use the middle wheel, or the medium wheel, for precision grinding. The third and final wheel, located on the right, completes the process with fine polishing. The blade selector dial is located in the center of the unit, just to the left of the medium wheel, and adjusts the slots' black or orange guides to create the best sharpening angle for blades of varying thickness. The Thick setting is for cleavers or hunting knives; the Medium setting is for utility, slicing, chef's and Santoku knives; and the Thin setting is for fillet, paring knives and other lighter blades. When I first turned on the Presto 08810 Professional EverSharp Knife Sharpener, it hummed a bit but was mostly quiet while it idled. During the actual sharpening process, the sharpener uses rapidly rotating, heavy-duty Sapphirite wheels to sharpen knives. Sapphirite is a hard, synthetic material — often aluminum oxide — used in professional knife sharpening shops to ensure effective blade sharpening. Because of the speed of rotation, these wheels produce a vibrating sound, which is normal but can be somewhat noisy. This noise only happened as I passed the dull blades over the grinding wheels, though; the machine is quiet the rest of the time while turned on. I had no trouble pulling my dull blade through the appropriate grinding slot, first doing so through the rough grinding wheel, followed by the medium grinding wheel and lastly through the polishing wheel. Using only slight downward pressure, I slowly pulled each knife through the various slots, straight towards me. As I finished pulling the blade through, I pulled up slightly so that my knife's tip left the slot on a slight upward angle. I did this three times in each of the slots so my blade achieved the correct sharpness. Before using the newly sharpened knife to slice food, the company advises you to always wipe the knife blade with a damp cloth to remove any metal filings that may have been deposited during the sharpening process. All in all, the entire process of using the Presto 08810 Professional EverSharp Knife Sharpener is intuitive. I do advise you to read the user manual before you first use the sharpener, as it contains important safeguards about the kinds of knives you can and cannot sharpen in the machine. For example, it warns against attempting to sharpen scissors, serrated electric knives or any blade that does not fit freely into its blade guides. The manual is available in English and Spanish and comes in the box, but it can also be downloaded from the Presto website. After scouring the internet for the most popular and highly rated knife sharpeners, I chose five models — four electric and one manual — to test. I placed each knife sharpener on a kitchen counter and assigned one dull blade to each. I sharpened the dull blades using its assigned knife sharpener, carefully noting how difficult it was to use to slice vegetables and fruits, both before and after sharpening. I spent several days testing each knife sharpener, evaluating each based on performance, durability, ease of use and value. Performance Tomato test: I used each dull blade to try to slice through a tomato and then sharpened the blade using its designated knife sharpener. After the blade was sharpened, I took another tomato and tried to cut it into thin slices, noting how easily the sharpened blade allowed me to do so. Avocado test: I used the dull blades to try to slice through the skin of a whole avocado and then used the sharpened blade to try doing so again. I noted whether or not I was able to easily cut through the avocado, as well as cut the inside into slices afterward. Durability Setup: I unboxed each knife sharpener, noting its overall size and weight, and if it came with detailed instructions, as well as how comprehensive the user manual was. Build quality: I held each knife sharpener in my hands, noting how sturdy or flimsy its construction felt. I noted the material and surface of the unit, as well as how big the footprint was. Ease of use Intuitiveness: I noted how well I could use the knife sharpener after just one perusal of its user manual. I observed whether the process required to sharpen each blade was wildly different from other knife sharpeners I tested or relatively the same. Speed: I considered how fast each knife sharpener was while sharpening each blade. Did I need to repeat any steps in the sharpening process, and if so, how many times did I need to do so to achieve the desired result? Overall value Price: I considered the price of each sharpener, factoring in the overall value of the sharpener itself as well as the money it saves on having to buy new knives. The knife sharpeners I tested all have slots that help position knife blades properly, practically ensuring you use the machine correctly each time. But there are three factors you should keep in mind as you search for the best knife sharpener for your needs. Electric or manual One of the first factors to consider is whether you want an electric or a manual knife sharpener. Electric knife sharpeners are bigger and take up more counter space, and might not be as easy to store as their manual counterparts. You can also take a manual knife sharpener with you while you go camping or hiking, without needing a power outlet. Keep your budget in mind as well. Electric knife sharpeners are generally more expensive than manual models, though I was somehow able to pick a manual knife sharpener in the Zwilling V-Edge that, at $100, is more expensive than any of the electric models I included in my testing pool. Sharpening stages All knife sharpeners offer grinding wheels to give blades a sharp edge. If a sharpener offers two wheels, then that's considered two stages. During the first stage, the blade is roughly ground, and then it's further refined during the second stage. There are some knife sharpeners, like my winner, the Presto 08810 Professional EverSharp, that also offer a third wheel or stage to polish up the blade even further. Knife type Whether your knife is serrated or not will drastically influence which knife sharpeners you can use. Sharpeners for non-serrated blades are much more prevalent, and all the models in this review can handle sharpening non-serrated blades. Serrated blades are a trickier thing, but some knife sharpeners can handle the unique needs of serrated knife sharpening, like the winning Presto sharpener and the Smith's Essentials Deluxe Diamond Knife Sharpener. Presto 08800 EverSharp Electric Knife Sharpener The Presto 08800 EverSharp Electric Knife Sharpener is the little cousin to our winner, the Presto 08810. This 08800 model offers a two-stage sharpening system that features two sharpening slots. It's effective and ideal for anyone wanting a smaller, more compact knife sharpener than my top pick. Like its cousin, the Presto 08810, this 120-volt model from Presto offers an intuitive, simple design and great performance, all from a compact unit. But the 08800 EverSharp Electric Knife Sharpener's smaller body has just two grinding wheels, not three. These two wheels use the same technique and technology as the 08810, quickly sharpening and polishing my non-serrated knife blades just as well as our winner. The first wheel on the left side of the Presto 08800 EverSharp is meant for precision grinding, while the wheel on the right is the fine polishing wheel meant for honing. I had no trouble pulling a dull blade through either grinding slot and then enjoying a sharp blade after just a few minutes of sharpening. This two-slot model from Presto is available for about half the price of the three-stage Presto 08810. Smith's Essentials Deluxe Diamond Knife Sharpener This compact, no-frills electric knife sharpener from Smith's sells for as low as $40, which is a great deal considering it gave me razor-sharp knives and even sharpened serrated blades. This model sharpened my dull knife quickly, letting me slice through tomatoes and avocados with ease. Smith's Essentials Deluxe Diamond Knife Sharpener is an electric knife sharpener that can sharpen knives of alloy steel, carbon steel or stainless steel. The right side of the Smith's body offers two slots. One slot is a mechanical slot that features a coarse diamond sharpening wheel for fast and precise sharpening. The other slot is a manual finishing slot that features two specially shaped, triangular ceramic stones for final edge honing of a straight-edge blade or serrated blade sharpening. The manual finishing slot's ceramic stones are designed to sharpen serrated blades without damaging the serrations by following the shape of the blade as the knife is pulled through the slot. This sharpener from Smith's is not designed to sharpen scissors or any blade that doesn't fit freely in its blade guides, which hold knives at the correct angle for precise sharpening. After using the Smith's Essentials Deluxe Diamond sharpener, my previously dull knife cut smoothly through tomatoes, avocados and more. It was also pleasant to use, with a soft grip on the left side that allows you to maintain better control while using it. The nonslip rubber feet on the bottom of the sharpener are a nice touch too since they provide extra stability. WorkSharp CPE2 Kitchen Knife Sharpener The WorkSharp CPE2 Kitchen Knife Sharpener is simple, easy to use, lightweight and compact that uses both discs and ceramic wheels to sharpen knives. It worked well and fit in my kitchen drawer for easy storage, which was nice, but it lost out to the Presto 08810 Professional EverSharp Knife Sharpener due to the Presto's three grinding wheels and lower price. The WorkSharp CPE2 Kitchen Knife Sharpener can sharpen all types of kitchen knives, including cleavers and paring knives, plus scissors, shears and serrated edges. Though I didn't test the latter, the company says this model offers 20-degree-angle guides that are removable for scissor sharpening as well as a dedicated scissor sharpening guide. The WorkSharp, like the Smith's and the smaller Presto, uses a two-stage system with two separate sharpening slots. The first one uses flexible, abrasive discs to sharpen blades, while the second is a honing port that uses ceramic wheels for fine-tuning. After using it, I like how I could store it easily in a kitchen drawer or cabinet. Its price is the highest of the electric knife sharpeners I tested, though, which kept it from taking the top spot. Zwilling V-Edge Knife Sharpener The Zwilling V-Edge Knife Sharpener is a manual knife sharpener that's lightweight, simple to use and effective. If you don't want to rely on a power outlet to sharpen your knives, this sharpener is a good option. It didn't earn my top spot since its price is higher than the rest of the electric models I tested, by about $30. The Zwilling V-Edge Knife Sharpener is the only manual knife sharpener I tested. It's portable, easy to use and works well, sharpening my knife so that I could easily slice through tomatoes and bell peppers. Its light, slim body can be stored easily in a pantry or kitchen drawer, or even brought along on a camping trip if you anticipate needing sharp kitchen knives. But be sure to keep it dry, as it's not water-resistant or dishwasher-safe. The company recommends keeping the guiding slot clean by using a nonabrasive, dry towel to gently wipe any fine dust residue that may accumulate over time. Also, at $100 or more, it's the most expensive option I tested, and it's results weren't vastly different. So, if budget is an issue, try one of the less expensive knife sharpeners I tested, like the $40 Smith's Essentials Deluxe Diamond Knife Sharpener, which works well. What's the difference between a kitchen knife and a utility knife? What's the difference between a kitchen knife and a utility knife? A kitchen knife is different from a utility knife (also known as a box cutter) because a utility knife stays sharp thanks to its replaceable razor blade. A kitchen knife needs either an electric or manual sharpener to restore its blade to ideal working condition. How do I use an electric knife sharpener? How do I use an electric knife sharpener? To use an electric knife sharpener, insert your dull blade into the correct slot on the machine and gently pull the blade toward you, applying gentle yet constant pressure as you pull. For dull blades, first choose the coarse slot, then select the finer slot for honing and regular maintenance after the initial sharpening. Can I sharpen serrated knives with my knife sharpener? Can I sharpen serrated knives with my knife sharpener? It depends entirely on the sharpener itself. Some are made to sharpened only non-serrated knives, while others can sharpen serrated knives, scissors, shears and more. Always refer to the manufacturer's instructions and user manual to determine what kind of knives are safe to use in your knife sharpener and how to do so. With our top pick, for example, the Presto 08810 knife sharpener, you can sharpen serrated knives, except for electric serrated knives or knives serrated on both sides, per the user manual. To sharpen non-electric serrated knives, Presto says to use only the slots in Stages 2 and 3, and to only sharpen the smooth side of the knife blade (the side without the grooves or scallops). Draw the knife through the slots using very little pressure too. Presto also warns that each time a serrated knife is sharpened, a portion of the serration is removed. So, be aware that, over time, the serration on the knife may be completely removed, and you may end up with a knife blade similar to that of a utility knife. Can I sharpen scissors with a knife sharpener? Can I sharpen scissors with a knife sharpener? You can sharpen scissors with some knife sharpeners, but not all of them. You can often sharpen scissors more effectively by using a sharpening rod, though, as many knife sharpeners are specifically designed only for knives. For those that can sharpen scissors, you'll want to first take the scissors apart and carefully pull each blade through the knife sharpener's slot, much like you would a dull knife blade.
