With offline recording and a camera.
Cinematic 4K, AI-assisted shots, offline recording, two-way privacy. Every material and every finish is the equal of premium outdoor eyewear that sells for a thousand yuan and up.
Camera and offline stills, offline recording, two-way privacy and a Bluetooth headset, all in the one pair. A frame made for children and teenagers to wear all day, built the way high-end sports eyewear is built. Retail ¥1,200; a ¥200 deposit reserves a pair.
The main mic sits at the center of the lower edge of the left rim, its port pointing down at your mouth. Faces come in different sizes, so that distance is 4 to 7 cm.
The reference mic sits in the upper right corner of the right rim, its port pointing up and tilted back, away from your mouth. Roughly twelve centimeters.
When you speak, your voice arrives at the main mic 7 to 9 dB louder than at the reference mic. When someone half a meter away speaks, the two mics are almost the same distance from them, and the gap is under 1 dB. The threshold sits at 4–5 dB. Anything below it is never written.
Take them off and it gets closer. Worn, that is 4–7 cm; off your face and held up to your lips, 2–3 cm. Same microphone, one movement.
Geometry beats any noise-reduction algorithm.
Layer oneNobody beside you hears what you say. The main mic is 4–7 cm from your mouth. You can drop to a level that is unintelligible half a meter away, and it still records you clearly.
Layer twoIt does not record anyone else. The main mic faces your mouth, the reference mic faces away from it, and the difference between the two levels is what decides. Someone half a meter away never clears the threshold.
The light stays on while it shootsBeside the camera, facing outward. Not a setting you can turn off.
Two-way privacy in a classroomMade for keeping your own notes and ideas during a lesson. Murmur or whisper and the teacher and the students next to you hear nothing; working from the geometry between the near-mouth main mic and the reference mic, the glasses record your voice alone and leave out what your teacher and classmates are saying. You intrude on nobody else's privacy, and you give away none of your own thinking.
FrameTR90, the nylon used in high-end American outdoor sports eyewear. It flexes under load and springs back, without taking a set.
Hinges and trimTitanium alloy. TR90 carries the structure and the electronics; titanium carries the load and the feel.
Temples6.5 mm thick, thin and wide. Wide enough to hold the electronics, and enough to shade the outer corner of the eye from side-on UV. Not a full wrap.
RimsBuilt on a conventional optical structure, so any optician can fit lenses to them.
ProtectionUV400, with a blue-light coating. IPX4.
Liquid siliconeSoft against skin, and it leaves no marks after hours of wear.
Air-cushion shapeA bigger bearing surface than a hard pad, so the pressure spreads evenly.
Better grip once you sweatWet, they hold steadier, not looser.
Two heights, swappableBoth are in the box.
Lenses are fitted to suit you, plano or prescription, and any professional optician can do it. The pale rose-gold lens is the one we recommend by default; it is not included by default. A white frame with pale rose-gold lenses is the signature pairing we suggest for children and teenagers.
What we recommendPale rose-gold against a white frame is bright and warm, but buy to suit the prescription you actually need — it is not included by default.
For childrenPick an impact-resistant, lightweight lens material; if there is a prescription, have the eyes tested and the lenses made at a professional optician.
You can order a custom pair of magnetic covers sized to sit exactly over the two camera lenses. Any emoji you like can be electroplated onto them. When you are not shooting, nobody can see there are cameras on your glasses.
The custom job is only ¥30, electroplated. Email us after your deposit with the emoji you want. It also makes the glasses recognisable at a glance as Razzhood 瑞兹帽.
The standard size uses specially sprung temples and a shaped temple profile, which fits most children and a good number of adults too.
The Razzhood platform is open and open-source. We give developers an SDK that reaches the camera and the audio on the glasses.
A parent can write an app by hand for one specific thing their own child needs, and your twelve-year-old — or your nine-year-old — can build one too. Neither you nor your child needs to know how to set up a server: our resident engineers will walk you through the deeper backend work, hands on.
Children know better than anyone what their classmates and friends want, and no adult product manager is going to beat them at it.
For a community developer, the hardest part is the cold start: where to find those first few hundred seed users. On the Razzhood platform you get there fast.
Because our rims are built on a conventional optical structure, they are not a sealed part that only takes a factory lens. Walk into any professional optician with these, and every lens they can make, they can make for this pair.
Myopia from 0 to 300 degrees, 300 to 600, above 600; long sight; astigmatism; progressives; photochromics; tints; tints with a prescription; photochromics with a prescription — all of it.

The store reference prices come from published rates at Chinese optical chains and, in the US, at LensCrafters and Walmart Vision Centers. They are there for comparison only and are not a quote from any of them. Astigmatism, progressives and unusual pupillary distances are priced separately — send us the prescription and we will confirm it before anything is made.
Razzhood AppOurs. Pairing, pulling photos, pulling recordings, managing the device.
An open platformPhone apps, desktop apps and pure web apps are all welcome on it.
Open interfacesPublished interface docs and a developer kit: pull photos, pull recordings, fire the shutter. Developers get the same set we use ourselves, published before we ship.
We build none of these ourselves; they are left to ecosystem developers. They are also the hands-on projects in Vibe Coder Basic.
OneA child photographs an animal outdoors.
TwoThe shot goes up to a cloud model, which turns the animal and everything around it into black-and-white line art.
ThreeThe line art is printed onto sticker paper. No sticker printer at home? Our partner will print them and post them to you.
FourThe child peels them off, colours them in, and sticks them anywhere.
These AI glasses are a springboard for a 2–6 year-old's imagination. The standard size uses specially sprung temples and a shaped temple profile, which fits most children and a good number of adults too.
My Photos, My UniversityTaking a picture starts an offline recording, tying the story the child tells to the photo itself. The AI only transcribes and tidies; it never makes the content for the child. Open that photo a few years later and you can still hear yourself at that age.
Stop-motion shortsA frame every three seconds, two hundred frames in ten minutes, cut automatically into a stop-motion short. Building LEGO, drawing, running an experiment, baking a cake, a plant growing — all of it records.
Voice notes on youAn idea usually lasts a few seconds. Say it out loud; back in the app it is transcribed, the key points pulled out, and filed into a personal knowledge base.
My drinks diaryOne shot of a drink logs it, and over time it builds a report on your own drinking habits. No scolding, no diet rules — it just lets a child see the choices they are making.
Sugar DetectivePhotograph the nutrition label on a package and the AI reads out what matters. The point is that a child learns to read labels for themselves, rather than being told what they may and may not eat.
Pay with a glanceNo phone out, no unlocking, no app to open. Look at the code on the counter and the payment is done.
The partnerNihaopay is a deep partner of China UnionPay. Coverage includes China, the United States, the Middle East and Southeast Asia. Its CEO, Rufei, expects platform transaction volume to reach $10 billion in 2026.
ReachThe first AI glasses in the world that can pay this way in China, the United States, the Middle East and Southeast Asia at once. Inside China, only Alipay has built the capability so far; outside China, no payment app has reached AI glasses at all.
Chinese-only interface at launchChinese families abroad can buy a pair too, and use Nihao Pay for small password-free payments.
“The first” is what we know as of publication. Actual availability follows whatever Nihao Pay covers.

A letter from the founder
Founder and CEO
My father built a chain of electric-motor repair shops. I grew up around copper wire, machines and money. As a kid I was a game merchant, flipping in-game gear from one platform to another.
Later I became an angel investor and backed the AI startup behind Lenovo's smart router, then sold part of my stake to Xunlei and JD.com. That stretch of my life taught me, first-hand, what smart hardware and wearables are — and what people really mean when they say a device is an entry point.
A few months ago, a friend doing AI research at OpenAI told me what he needed: to talk to his coding agent anywhere, at any moment — not sitting at a desk, but anywhere, in a very small voice.
Razzhood began with that sentence. It does not think. It catches every word you said, whole, and hands it back to you.
