Adding Wi-Fi doesn’t always turn out to be as smart as it sounds. A smart smoke detector turns out to be dumber than I thought, even with Wi-Fi added.

Smart smoke detectors will let you know if a fire breaks out when you aren’t home, but other than that they don’t offer any extra benefits over a “dumb” model. And these devices introduce a problem: Most smart smoke detectors exclude one of two sensors to alert you about a fire. Every smart model I tested had only a photoelectric sensor, which picks up smoldering fires, while ionization sensors that pick up fast-burning fires were left behind. Ionization sensors are more likely to have nuisance alarms go off (while you’re cooking, for example), but it’s still a sensor you should have somewhere in your home, especially since modern building materials have shortened your window of time to escape a home fire.

It’s not to say smart smoke detectors are useless, since what matters most is having a working smoke detector at all. A photoelectric-only smoke detector is still a good smoke detector and will pick up smoldering electrical fires in your walls and similar-style smoke. Still, you’ll want to make sure there is an ionization sensor or two in your home, more so than needing a Wi-Fi model added. There are dual-sensor smoke detectors you can get too, but no smart models just yet with both sensors. Here’s everything you need to know if you’re considering getting a smart smoke detector for your home.

Does a Smoke Alarm Need to Be Smart?

You already know what a smoke alarm is: a device that sits on the ceiling (or sometimes high up on a wall) to alert you if it senses smoke in a home or building. Most buildings, whether residential or commercial, come equipped with modern smoke alarms to match current codes. In recent years, it’s been another device to go “smart,” or at least become Wi-Fi compatible. It’s not smart the way a smart thermostat would be, since you can’t meaningfully exert control over it over Wi-Fi. You’ll simply get alerts on your smartphone of choice when smoke is detected, so you’ll know if a fire happens while you aren’t home, in addition to the blaring of the regular alarm.

Is it necessary? No, but it’s a nice-to-have feature to get alerted, no matter where you are, if smoke is detected. But it’s not required to make these devices function, and it won’t help you with the speed at which fires are moving through newer homes.

“While newer smart features like Wi-Fi alerts and app connectivity can be convenient, they’re not essential for safety,” says Steve Clemente, president and COO at Mister Sparky, an electrical services company. “A well-placed, properly powered detector will do far more to protect your home than extra features like air quality monitoring. One exception worth considering is a combo smoke and carbon monoxide detector, which adds an extra layer of protection.”

How Do Smoke Alarms Work?

Smoke alarms have built-in sensors to sniff out smoke in your home. There are two primary sensors included: photoelectric and ionization. “Photoelectric models are better at sensing slow, smoldering fires—like upholstery or wiring—while ionization models respond faster to quick, flaming fires,” says Clemente.

He says neither is universally better, and rather the two styles are complementary. The National Fire Protection Association recommends having both types of smoke alarm sensors in your home, or a smoke alarm that has both sensors built into it (these are usually called dual-sensor smoke alarms). The NFPA doesn’t have any specific codes about which type of sensor you need to put in your home, but a spokesperson did recommend putting photoelectric smoke alarms near kitchens and bathrooms, since they’re less likely to be set off by daily use in these rooms (things like steam and cooking smoke are more likely to set off an ionization alarm).

However, all the smart models I tested included only photoelectric sensors. As I continued researching, most smart smoke alarms seem to only include photoelectric sensors, leaving out ionization altogether. It’s likely because of the sensitivity of ionization alarms. That’s a problem for me after talking to Nicole Sanders, public education lead for UL Research Institutes’ Fire Safety Research Institute, who warned me that new data shows you might only have three minutes to escape a house fire.

Other Standing Desks to Consider

Luxor Compact Electric Standing Desk for $200: The Luxor is a no-nonsense standing desk that does exactly what you expect and takes up minimal space. It’s perfect for students, small apartments, and anyone who needs a compact, budget-friendly setup. At 23.5 inches deep, the tabletop is shallow enough to fit into tight corners or shared spaces. The electric lift moves steadily at an inch per second, whisper-quiet, and the 154-pound weight capacity can handle a laptop, monitor, and a few textbooks with no sweat. The lift mechanism is exposed underneath, so you’ll want to leave some legroom when at sitting height. —Nicole Kinning

Simple Height Adjustable Desk for $850: The Simple Height Adjustable Desk lives up to its name. Assembly is straightforward and cable routing is tidy thanks to an integrated channel that keeps everything corralled. The T-shaped legs slide into a bracket instead of screwing or locking into place, which feels a little ambiguous, but once it’s upright, the desk is solid and sturdy. In practice, the desk became everything I needed. It’s smooth, quiet, and spacious, with four height presets. The laminate top is durable and forgiving—ideal if you’re like me and regularly forget that coasters exist. There are no fancy gimmicks, which is exactly the point. It’s a dependable, fuss-free desk that prioritizes function over flashy. —Nicole Kinning

Autonomous Desk Pro for $600: The standout feature here is the new Desk AI, a separate control attachment that tracks your standing habits along with environmental factors like air pressure and quality, temperature, humidity, and noise. In theory, it’s meant to help you work smarter, but in practice, it mostly flags things you can’t control from the desk itself. If it came with an air purifier or fan to manage these conditions, then we’d be talkin’. Still, it’s a fun and techy bonus on an otherwise reliable desk. —Nicole Kinning

Vari Solid Wood Electric Standing Desk for $1,500: Even though it’s solid wood, this desk never felt too precious for everyday use. Made from FSC-certified lumber, the desk is heavy and stable, even at standing height on carpet, and the motor is impressively quiet and subtle when adjusting. The ComfortEdge feature turned out to be more helpful than I expected; over long typing sessions, it noticeably softened where my wrists meet the desk, a nice upgrade to a standard desk’s hard, squared-off edges. Yes, the solid wood Vari is on the pricier side, but it feels justified if solid wood and long-term durability matter to you. If they don’t, consider the traditional version. —Nicole Kinning

Boulies Magvida for $760: The Boulies Magvida advertises its best feature in the name itself. This mid-size desk (55 x 28 inches) is known for its EMO system, a magnetic organization setup built beneath the desktop. Instead of drilling holes or fiddling with brackets, you just snap accessories like a cable tray, hooks, and silicone straps, into place. The add-ons feel premium and the magnets don’t budge, and there’s an optional magnetic drawer that’s also handy. Add in memory presets, a child lock, anti-collision detection, and simple color options and you’ve got a clean, clever setup. —Nicole Kinning

Herman Miller Jarvis Bamboo Standing Desk for $1,625: As someone who spent years hunching over keyboards, obsessive research led me to the Jarvis Standing Desk (now owned by Herman Miller), which has served me well for six years. With a contoured bamboo top, handy optional extras to tuck wires out of sight, and a responsive control panel for easy height adjustment (including presets), this is an excellent standing desk. The only weakness is that it wobbles slightly at higher levels. The newer touchscreen OLED control unit is not as reliable as the original, so opt for the programmable controls. —Simon Hill

Staples Union & Scale Electric Standing Desk With Micro Movements (UN62092) for $513: Staples’ house brand, Union & Scale, makes some of my favorite affordable office furniture, and its standing desk is no exception. It was easy to put together, and while the white desktop is not much to look at, the dual motors do the job. I like the control panel, which has dedicated buttons for moving the desk up and down, as well as two height presets. I didn’t see any wobble, though the collision sensor could stand to be more sensitive. There’s a cable tray at the bottom back of the desk to route cables, but there’s sadly no grommet to pull them through. The Micro Movement mode. moves the desk up and down over time to reduce fatigue and encourage movement, but I found it more distracting than useful. —Julian Chokkattu

Beflo Tenon Premium for $3,998: While incredibly expensive (and heavy!), this hardwood smart desk is both sturdy and well designed. Assembly was straightforward, and once the desk was up and running, I found all of the features (touchscreen controls, a built-in power strip, audio passthrough, and LED lighting) to work well, and in convenient locations. The touchscreen controls are intuitive (iOS-like), and features like a sit/stand timer and phone connectivity provide additional functionality. The desk supports over 200 pounds of stuff even when moving, and the height-adjustment motors will temporarily disable if they overheat, instead of risking damage to the desk. The table also looks fantastic, and a multitude of first-party accessories let you customize the desk to your specific needs. My largest issue with this table is the noise. While in no way loud, it was certainly more audible than the “whisper-quiet” descriptor Beflo uses in its marketing. Besides that, the lighting color adjustment had some difficulties creating specific colors using the built-in touchscreen, and the audio cable was too short to reach a desktop computer on the floor, even at the lowest height. However, the Tenon is still a great, if pricey, option to consider. —Henri Robbins

Herman Miller Spout Sit-to-Stand Table for $3,275: Herman Miller’s Spout Sit-To-Stand Table is lovely to look at. Like the Branch Four-Legged Desk, it looks like a normal desk with four legs, giving it a luxe look. Those motors in the legs rise smoothly, and it’s easy to raise and lower the desktop to my preferences with the button on the right. The motor does have a high hum to it, and is loud enough that I’d hesitate to use it when my husband is on a call in the same room, but not so loud it would disturb my son if he were sleeping a room away. Bizarrely, it doesn’t have memory presets, but I found it pretty easy to just adjust the desk to my preferred sitting and standing heights each time. You can add a cable tray underneath the desk to organize cords, but it costs extra. The only other item built into the desk is a single slim center drawer perfect for pens and notebooks. It comes in three desktop sizes and three finishes: laminate white, veneer walnut, and veneer ash. You can also customize the base color, with seven different colors ranging from your classic black and white to a gentle blue and olive green. While it’s gorgeous to look at and works well, it is disappointing that such a high-priced desk doesn’t have presets and uses veneers rather than real wood. —Nena Farrell

Flexispot E7 Pro for $400+: Standing desks can get pricey, but Flexispot routinely offers similar functionality at a lower price. At first glance, the E7 Pro looks much like the Herman Miller Jarvis, but look closer, and you discover the entry-level option has a shallow 23-inch desktop, the control unit feels a bit cheap, and it emits a high-pitched whine in operation. I also had some issues fitting larger power adapters in the cable tidy, and it can get wobbly when fully extended. But, even when fully configured, the E7 Pro is cheaper than many rivals. Minor flaws aside, it is a perfectly decent standing desk. —Simon Hill

Inbox Zero 47-inch Adjustable Electric Standing Desk for $163: This desk has every feature I need for just about $200. There are rolling casters so you can not only move the desk up and down, but also shake it all around. It has electric controls that have presets but also allow you to fine-tune the height—my actual use-case for standing desks, as I don’t like standing to work as much as I should, but I do like to adjust the height to accommodate changes in my posture when I’m typing versus Zooming. The split top that makes it easier and cheaper to ship doesn’t hurt the performance, but is less pleasant visually, and the little motor works audibly hard (tshunk, tschunk, tshunk) while raising the desktop. After three months of testing, I’d recommend it to someone who needs a budget standing desk with casters, but if you can spend a little more, you’ll probably be happier with something else. —Martin Cizmar

Branch Clamp-on Power for $89: This simple and elegant clamp attaches to your desktop and adds three AC outlets, a USB-C, and a USB-A, so you don’t have so many wires running down to the ground. —Julian Chokkattu

LumeCube EdgeLight 2.0 for $150: Why have a lamp take up valuable desk space when you can clamp the lamp to your desk? These task lights from LumeCube are great for illuminating the desktop and even your face during late-night Zoom calls. You can adjust the color temperature and the brightness. —Julian Chokkattu

BenQ ScreenBar Lamp

BenQ ScreenBar Lamp for $139: Alternatively, you can place these ScreenBar lamps over your computer monitor, and it will light up your desktop, no clamping required. The ScreenBar Pro also has a motion sensor, so when you leave your desk, the lamp will turn off, and it will light up when you’re back. You can adjust the brightness and color temperature, and an automatic setting makes it adjust these controls based on the room’s ambient lighting. —Julian Chokkattu

Secretlab Premium Footrest for $89: I’ve been using this footrest for several years, and it’s excellent. The plush memory foam is cushy and a nice respite for my feet, and it’s easy to clean with a vacuum and a damp cloth. It hasn’t shown much wear despite years of use. —Julian Chokkattu

Monoprice Single Monitor Adjustable Gas Spring Desk Mount for $84: I’ve had a few of these WorkStream arm mounts for years, and they’ve reliably done the job. You can adjust the tension with a hex key and move the monitor around to your desired position. Just make sure you don’t go over the recommended weight load with a big and heavy screen. —Julian Chokkattu

Mount-It! Dual Monitor Arm for $280: This heavy-duty monitor arm holds up my ultrawide monitor and my vertical monitor, both of which have BenQ Screenbar lamps on top, along with my webcam. It handles the weight with no effort, and the clamp is accommodating enough to even work with the 5-inch Room & Board standing desk. There’s RGB lighting throughout, but it’s not bright enough to splash onto the wall, so it’s a little pointless. —Julian Chokkattu

Harber London Professional Desk Mat for $239: Keep your desktop protected with a large desk mat like this one. I’ve used several mats from Harber London over the years, and this latest model is my favorite. The pebbled leather is supple and soft, and the mat stays put. It’s easy to clean too. —Julian Chokkattu

Avoid These Standing Desks

Corsair Platform:6 Desk

Corsair Platform:6 Desk for $1,400: Where do I start? I liked Corsair’s standing desk because it’s spacious, has a fun pegboard design to mount your tchotchkes, and even has an interesting rail system that lets you mount and slide things across the desktop, like your monitors. Unfortunately, several months after mounting two monitors on the included dual-monitor arms, this rail system has tilted forward due to the weight. (I’m also not the only one to experience this.) It doesn’t help that I never really found this rail to be all that useful. The standing function works well, and you get two presets, but sometimes the little screen would throw me an error message “rE5.” Pressing and holding the down button resolved it, but none of these are issues anyone should deal with considering the crazy-high price. That’s the real problem. It’s just so expensive, and the five-year warranty feels like a slap in the face. —Julian Chokkattu

Marinamantra ‘Flow’ Sit-to-Stand Desk for $1,049: I had high hopes for this one. A desk that lets me sit criss-cross applesauce while I work?! Sold. But the reality didn’t live up to the pitch. When I unboxed the desk, several screws were scattered loose in the box. That set the tone for a desk that eventually worked, but often misbehaved, sometimes refusing to move up and down. That said, I do like the cord management lip and the clever velcro covers that keep cables and hardware neatly tucked out of sight. Unfortunately, none of that matters much if I’m spending more time flipping it over and poking around underneath the hood than actually using it. —Nicole Kinning

ErgoAV Standing Desk for $2,000: I’ve wanted a standing desk for years, so I was extremely excited to try out this one from ErgoFx. For almost two grand, it comes jam-packed with features including a wireless charging pad that automatically lifts and rotates towards you, a five-outlet power strip, and a built-in drawer to put all your office supplies in. You can also control it via the companion app. It has a super durable laminated MDF desktop and a carbon-steel frame and looks sleek. Unfortunately, only a few months into using it, I started having issues where the desk would get stuck at a specific height. This would typically happen if I didn’t adjust it for a few days or weeks. The only way to solve this was by unplugging the power cord and plugging it back in. After each reset, it would work normally again. But this issue comes back every time, so that I’ve stopped trying to fix it. It’s become more trouble than it’s worth—especially at this price. —Brenda Stolyar

To anyone with a pulse and a smartphone, it’s obvious that the internet has an AI slop problem. The issue has grown more severe since ChatGPT launched in 2022, with some social platforms flooded with AI-generated writing. Now, there’s data to back up the anecdotal evidence.

A new preprint study published today from researchers at the Imperial College of London, Stanford University, and the Internet Archive found that approximately 35 percent of all new websites are either AI-generated or AI-assisted. The same study also found that online writing is “increasingly sanitized and artificially cheerful.” In other words, AI is making the internet fake-happy.

The research team tried four different approaches to AI detection before settling on tools from Pangram Labs after it delivered the most consistent results. (Though the team found it performed well on its tests, it is worth noting that all artificial intelligence detection tools are imperfect.) To compile a representative sample of websites, it tapped the Internet Archive’s Wayback Machine, which collects snapshots of webpages. In addition to quantifying how many sites created between 2022 and 2025 lean on AI-generated writing, the study also tested six different theories about the characteristics of slop.

The test that looked into artificial cheerfulness examined how AI affected the tone of online writing. Using sentiment analysis, which classifies words as positive, neutral, or negative, it found that “the average positive sentiment score of AI-generated or AI-assisted was 107 percent higher than that of non-AI websites.” The researchers see this spike in artificial happiness as a “symptom” of the “sycophantic and overoptimistic nature of existing LLMs.” In this way, AI writing tools’ tendency to suck up to their human users has a spillover effect, making the overall tenor of online writing more saccharine.

Another test investigated whether the increase in AI-generated writing shrinks “the range of unique ideas and diverse viewpoints” on offer. The researchers found that AI did make the internet less ideologically diverse, with AI websites scoring roughly 33 percent higher on testing for “semantic similarity” than human-made websites.

While those two tests validated the researchers’ assumptions about AI, others did not. Four theories that the researchers tested were not confirmed. Notably, they had suspected that AI would lead to a rise in misinformation, but their analysis of the evidence did not support the hypothesis. They had also guessed that AI writing wouldn’t link out to external sources, and that it would be stylistically more generic than human writing. Confounding expectations, neither of those theories were supported by the evidence, either.

While the analysis found that the ideas espoused by AI writing were more homogenous—and specifically, more consistently cheery—the writing style itself was not confirmed to be flattened. This came as a big surprise to the researchers, who had assumed they would see a clear move towards more generic output. “Everyone on the team expected that to be true,” says Stanford researcher Maty Bohacek. “But we just don’t have significant evidence for that.”

Prior to conducting its analysis, the research team commissioned a poll on how people feel about AI. Comparing it to the results, it discovered that the researchers weren’t the only ones who had their expectations upended. Many commonly held beliefs about AI writing are wrong, their study finds.

Like the researchers, most people polled had also assumed that they would encounter a rise in fake news as the amount of AI-generated websites they saw increased. The vast majority of respondents had also assumed that AI writing would stop linking to external sources, and that it would have an increasingly generic, uniform voice. “It’s interesting to see that people tended to expect the worst outcomes,” Bohacek says.

This study is far from the last word on what AI is doing to the internet. “We just wanted to break ground,” says Bohacek, who sees this as a jumping-off point for deeper exploration. As a snapshot of AI slop’s impact, it offers a particularly human flavor of insight: Sometimes, it’s simply hard to predict how things will unfold.
