Why Perchi has no AI, no microphone and no battery
Perchi has no AI, no microphone, no camera, no speaker and no battery on purpose: they are the parts desk robot reviews complain about most. Here is why.

Perchi is a silent desk companion and phone stand from MyPerchi, and it has no AI, no microphone, no camera, no speaker and no battery. None of that is a cost saving we hope you will forgive. Each one is a decision we took after reading what owners of Eilik, EMO, Loona and Vector say once the unboxing video is over, and each one removes a complaint that shows up in review after review. Here is the reasoning, what we kept instead, and what the trade costs you.
What do desk robot reviews complain about?
Four things, in the same order on almost every product: the battery, the noise, the app and the cloud. This is what the vendor pages and review sites said on 18 September 2026.
| Product | Battery per charge | Sound | Needs an app | Cloud or AI | Most-cited complaint |
|---|---|---|---|---|---|
| Eilik | 450 mAh, 1.5 hours (vendor spec) | 3 W speaker, servos | No | No AI | Battery, across about 1,145 store reviews; speaker "surprisingly loud" |
| EMO | About 2 hours | Speaker, microphone | Yes | ChatGPT through the maker's cloud; camera | App "crash-prone", slow support |
| Loona Petbot | 2 hours | Motors audible in quiet rooms | Yes | GPT-4o in the cloud; camera | Navigation, gearbox failures, motor whir |
| Vector 2.0 | Short; lives on its dock | Motors, speaker | Yes | Cloud, behind a paid membership | USD 11.99 to 14.99 a month to answer its name |
Battery is the first complaint for Eilik and EMO: Eilik runs about 1.5 hours, EMO about 2, Ropet 2.5 to 3.5, Moflin 5, and owners describe EMO as "effectively tethered to its charger". Then noise: Eilik's speaker is called surprisingly loud in quiet offices; Loona and Moflin owners mention motor whir at night. Then the app, which EMO owners call crash-prone; one Trustpilot review counts about 25 attempts at a firmware update. Then the cloud: a companion that thinks somewhere else stops thinking when that somewhere else has a bad day. We wanted to remove the parts, not improve them.
Why does Perchi have no microphone or camera?
Because nothing on your desk should be able to hear or see you unless you asked for that, and we could not think of a feature worth the trade. EMO and Loona carry both because face recognition, voice commands and cloud conversation need them. Perchi's features need neither: it reacts to your touch, your phone resting on its back, and real events from the apps you connect.
That shapes what leaves the device. Raw touch and phone-presence readings never go anywhere; only block events, the planned and focused minutes and the project kind sync to your workspace, and report cards carry no timestamp finer than a minute. Focus rooms share state only, never what any app shows. Retention periods are on the security page.
Why no speaker?
Because the places a desk companion is most useful are the places a speaker fails: a library, a shared hostel room, an open office, a late-night call. Eilik's speaker is its second most-cited complaint, and Enabot's EBO Air 2 runs at 61 dB. Perchi's celebrations are silent confetti on the screen: a sale gets a party face, a green build a proud one, a failed build a worried one. One line in the product brief became the test for every animation: calm enough to sit next to for 8 hours.
Why no battery?
Because a desk companion lives on a desk, and the cable is the feature. Perchi runs from USB-C at 5 V, from the same hub as your monitor or any phone charger, and it is simply always there: no charging routine, no dock, no 3 percent warning during the block you most wanted to finish, no cell to swell after two years on a warm desk. The trade is that Perchi does not travel; it will not ride in a bag like Mirumi. We do not print power draw, weight or dimensions yet, because the hardware bench pass has not happened; those numbers appear when they are measured on production units.
Why no AI?
Because a desk companion's job during working hours is to be present, not to talk, and because the talking robots' owners are the ones complaining. EMO answers questions through ChatGPT in the cloud; reviewers report an English-only voice that "degrades in noisy rooms or with strong accents" and, for some buyers, a robot that responds to roughly 1 in 20 questions out of the box. Vector 2.0's assistant sits behind a USD 11.99 to 14.99 monthly membership, without which "Hey Vector" gets no response; when Anki went bankrupt in 2019, owners were left with robots that could not answer to their names. Reddit threads on Eilik and EMO end the same way: "not interesting after two days".
Perchi's expressions come from things that happened, not from a model guessing what to say. Its face is parametric, 13 parameters and 10 moods blended by code on the device, and deterministic: the dashboard preview shows the exact frame the screen shows. A payment makes it party, a new follower love-struck, a green build proud, a red build worried, a calendar event five minutes out curious. Nothing on Perchi listens, and no language model runs on it. The one place AI touches the product is on your side: an assistant on your computer can send a message or set a mood through the dashboard's MCP server.
What did we keep instead?
- A face that reacts. It blinks toward a tap, breathes on a 4-second cycle, leans into a stroke, and returns to neutral after 3 minutes so it never sticks in one expression.
- Phone Nap. Rest your phone on Perchi's back and, after a 3-second ring, a focus block starts: 25 minutes by default, 5 to 120. Lift the phone and Perchi pauses with a look; put it back within 60 seconds and it carries on (how Phone Nap works).
- Projects. During a block Perchi knits a scarf, grows a sprout or builds a tower in 5 stages; every finished one goes into a wardrobe in your dashboard.
- Moments. Real events from 60+ integrations, the same library that runs Perchi Matrix: the face changes first, then a card with the value slides in beside it.
- Company. A focus room of up to 4 Perchis shows each other's state as dots, and two linked Perchis can tap each other. The pair is sold as Perchi for two.
- A web dashboard. Pairing happens from a browser over Bluetooth in about a minute. No app to install, no account wall before the first smile.
What does this cost you?
A lot of what sells the category. Perchi does not move: Eilik tilts its head and waves its arms, EMO walks, Loona drives like a small animal, and that motion is the hook in most unboxing videos. It does not talk or understand you, so if you searched for an AI desk robot you should buy one; the Perchi and EMO comparison and the guide to cheaper EMO alternatives say where the talking robots win. It has no mini games, it is desk-bound, and its 128x64 monochrome OLED is the same resolution as Eilik's face. What Perchi has that none of them have is a reason to exist during work hours, a phone stand built in, and a price a student in India can pay; the Perchi and Eilik comparison has the dated prices.
What we promise, and what we do not
The core loop works offline: the face, Phone Nap, projects, streaks and the clock run on the device with no Wi-Fi, and blocks finished offline are kept in a 64-entry ring and synced later. An authenticated local API and MQTT with Home Assistant discovery keep working on your LAN without our servers. Firmware updates are signed with a key that never touches our servers, the device trial-boots each new image and rolls back by itself if the update fails, and a unit that crashes three times in a row boots into a safe mode that still keeps the clock. We call this "designed so a shutdown cannot brick it", not a guarantee.
What we do not claim: a third-party security audit (there is none yet), hardware-level boot verification or flash encryption in the shipped firmware (the released images have neither), or any hardware figure before the bench pass. The full list is on the security page.
Where Perchi fits
Perchi is for people who fight their phone for attention and want their desk to feel a little alive: students in exam season, people working from home, creators who want a face in frame. It is not for children under 8, not for anyone who wants conversation or motion, and not for anyone who needs the phone locked away rather than parked. The Perchi page has the specs and the "what Perchi is not" list, what is a desk companion explains the category, and you can reserve a Perchi without paying anything today.
Questions
Is Perchi a robot?
No. A robot moves or performs; Perchi is a desk companion, a small always-on device that reacts to the person at the desk. It has no motors, wheels, arms or voice. What moves is the face on its screen, and what it reacts to is your touch, your phone and real events from your apps.
Will Perchi get AI later?
No, and the hardware makes that a promise rather than a preference: there is no microphone or camera to add voice or vision to, and no update can put one there. The only AI in the picture is optional and on your side, through the dashboard's MCP server.
Can Perchi play sounds through my phone?
No. Perchi has no speaker and no audio link to your phone. The only thing it senses about the phone is that it is resting on the back plate; Bluetooth is used once, during pairing from a browser, and never for audio. Perchi stays silent by design.
Does no battery mean Perchi turns off in a power cut?
Yes. Perchi goes dark when the power goes, like a monitor, and wakes with a stretch when it returns. Your streak and every finished block are stored on the device and synced later, so nothing you completed is lost. Any 5 V USB source keeps it running, a laptop port included.
