@RattlePokemon @caydengineer With android, you can

[cayden 凯登 @caydengineer]

Our smart glasses now work as a USB webcam.

Plug them into your laptop and your computer sees from your point of view.

Use it in Google Meet, Zoom, OBS, Python, or straight to your OpenClaw.

We're making smart glasses so open, you don't even need our app.

I connected @interaction with my Even Realities G2 via @MentraGlass and now it can chime into my irl convos whenever it wants with transcription and messages on the display.

My god this is cool.

Context is king

In the year 2000, Windows OS had >90% market share.

Over the next few years, phones went smart, and they needed an OS. Microsoft tried to copy-paste Windows onto phones. It was a train wreck.

But Android showed up and considered the new challenges of power usage, touch screen UI, and mobility, and they designed for these from the start. That led to a better solution that now has the vast majority of smart phone market share.

It’s now 2026, and glasses are going smart. Incumbents think they will copy-paste their existing phone OS onto the glasses. But they’re not considering the new challenges of power usage, glasses UI, and proactive/contextual interaction.

That’s why we’re building MentraOS. We believe smart glasses need to be great eyewear first, or they’ll never get adopted. This introduces massive challenges around lightweight (<40 grams with Rx lenses), all-day battery, and the ability to run multiple apps simultaneously that are listening and can activate at any moment.

We don’t believe the previous generation of operating systems will enable that to happen. MentraOS treats the glasses as lightweight, simple input/output devices and offloads all the heavy processing to the phone. That enables sleek, light glasses that run all day. MentraOS has an app runtime and orchestration layer on the phone that assumes multiple apps are running and listening at the same time. This enables proactive AI that helps you the moment you need it.

Just as important, MentraOS is 100% open source. OEMs building glasses need access to the source code to move fast, make modifications, and ensure they continue to own the stack.

What’s this mean for you? As a user, it means that you get the best glasses experience, where your daily prescription glasses go smart and offer you new value in daily life. As a dev, it means you can write 1 app that runs on any pair of smart glasses. As an OEM, it means you can focus on building great hardware because the app ecosystem is handled by MentraOS.

100s of companies are deploying MentraOS right now. Want to start building on MentraOS? Get any pair of supported glasses and get building.

Big streamers are going live from their Mentra Live smart glasses.

More to come ;)

We put 1000s of hours into building open-source camera glasses

And now we're giving away everything we learned for free.

Checkout this in-depth teardown of the Mentra Live smart glasses.

As an OS company, our goal is to spread our OS. That goal encourages us to do crazy things, like build the world's best AI glasses for business and then show you how we made them... all in the name of spreading the OS.

It also convinced us to make it 100% open source, so adoption is faster and easier. We're at risk of our competitors easily copypasting our code now... all in the name of spreading our OS.

Now we've built the glasses for you, and we've taken the risk, and we've released an open SDK.
Now your AI apps and agents can enter the real world on smart glasses. So now, what will you build?

Launching full support for Even Realities G2 smart glasses in MentraOS.

With Mentra, you can run multiple smart glasses apps at once.

You: in a meeting in Tokyo on 82nd floor. You're running translation on your smart glasses and understanding every word. Your Notetaker is running in the background capturing ideas as they're spoken. Your proactive AI agent is listening in, hears someone ask a question, and automatically overlays the answer on your vision. That's what's Mentra unlocks.

MentraOS is the open source OS for smart glasses. We give users an app store and allow developers to write one app that runs on any pair of smart glasses.

It's 100% open source, private, and free.

How to use: Download the Mentra app, connect your G2, and get instant access to captions, AI notetaker, Merge proactive AI, translation, and other apps. You can switch back to the Even app at anytime.

If you want to unlock your Even G2, then downalod Mentra on the Google or Apple App Store.

Introducing the Mentra Bluetooth SDK - control smart glasses directly from your Android/iOS app.

Thousands of devs built smart glasses apps. But we heard one common complaint.... the cloud.

So we stripped it out and gave you direct glasses control straight from your phone app.

[cayden 凯登 @caydengineer]

Launching Mentra Live open-source smart glasses.

Deploy smart glasses for real world work.

We already shipped thousands. Now, they're generally available.

Build apps that leave the screen. Let your AI step into the real world.

[cayden 凯登 @caydengineer]

I don't care about 99% of these smart glasses launches.

They all have the same problem.

They try to wrap a phone around your head instead of building great eyewear.

Big tech and startups keep launching heavy/uncomfortable glasses. Users try them, they're fun for a while, then they end up in the drawer because they're not realistic to wear everyday.

How many smart glasses founders actually wear their glasses everyday?

Of course it's not just weight - balance, material, fit, visual comfort, 2-eye display are all critical to comfort.

We designed MentraOS from the ground up to be an OS for eyewear.

MentraOS is the only way to enable eyewear that is both truly smart and truly eyewear. We let the phone and cloud handle the computing and apps, and keep the glasses lightweight and focused only on I/O.

If you're a dev, you build smart glasses apps on MentraOS. If you're a smart glasses OEM, you embed MentraOS into your glasses and app. If you're a user, MentraOS disappears in the background so you can focus on augmenting your intelligence and communication.

Lightweight smart eyewear is about to change how we interact with each other and with AI.

Y'all screaming that AI is a supersonic tsunami that will touch everything

How's it supposed to touch the physical world if it can't help people in real life?

Answer: with smart glasses.

Smart glasses let AI see what you see, hear what you hear, and whisper help in your ear.

Like this mechanic, who asks a quick question. The AI sees the car model and part, listens to the question, and provides an instant answer in his ear.

Knowledge work is only 30% of the world's economy. The rest of the economy is physical, where a chat-based interface cannot go. The physical work AI revolution, powered by smart glasses, is about to take the world by storm.

That's why we build Mentra Live as a platform. Mentra can't build and deploy every app. We won't even try. We provide the platform, and thousands of companies build on our platform and deploy their apps using Mentra hardware and OS as their infrastructure.

And you could be next... or you could wait for someone else to augment your physical industry with AI.

Low latency streaming from your smart glasses

[cayden 凯登 @caydengineer]

I just called my Mom from my smart glasses.

Introducing video calls on Mentra Live smart glasses. Join Google Meet, Teams, or Zoom call directly from your glasses.

Imagine field workers like HVAC techs, electricians, or mechanics calling into an expert remotely. The expert can see what they see and have a live voice call with them, getting help exactly when they need it.

You might have seen a demo like this before... so what's different here? It's all about wearability. Classical enterprise smart glasses are heavy, uncomfortable, and never make it past pilot pergatory.

Mentra Live are super lightweight and shaped like regular glasses. Workers can wear them all day, and the battery lasts for a full shift.

Also, since MentraOS is open-source, you can build your own apps, deploy on-prem, and stay fully compliant.

Video calling is rolling out in general availability to Mentra Live users later this month.

My 2026 I/O

[cayden 凯登 @caydengineer]

30% of the world's economy is tapping away on a keyboard or scrolling on X (like you).

AI has completely changed how they work.

Yet the other 70% of the world's economy is in the physical world, untouched by AI... until now.

Mentra Live smart glasses are how devs and businesses build apps that let AI operate in the physical world.

Powered by MentraOS, Mentra Live is an open source platform that lets you build anything you want.

The camera gives eyes to your AI. The speakers let your AI communicate back to workers in real time. Voice commands, buttons, touch pad, and mobile app let users control the system.

What will you build when your apps and agents can step into the real world?

Mentra glasses cameras are pretty good,

I created a auto-document scanning app for the opensource smart glasses.

We worked 996 in Shenzhen making smart glasses so you don’t have to.

AI has made us 100X smarter… unless you work in the physical world. That’s because AI can’t see, can’t hear, can’t act in the physical world.

But now with smart glasses, it can.

But making smart glasses is really hard and expensive and you’ll probably fail.

That’s why we made open source smart glasses, so you don’t have to. Mentra Live is for building and deploying apps that let AI see, hear, and act in real time.

Think of frontline workers wearing smart glasses as AI whispers repair instructions in their ears, salespeople getting live tips to close a deal, manufacturing inspections verified with AI vision, delivery drivers saving minutes per door.

The software under-the-hood (MentraOS) is open source, which means you own the app, the data, the glasses, the deployment.

You can start deploying smart glasses now. Mentra does the glasses OS, hardware, and infra - you build the app and deploy it.

What will you build?

We built and shipped smart glasses from scratch in 12 months. The hardware wasn't the hardest part.

A year ago we launched MentraOS 1.0, the first open operating system for smart glasses. Early adopters could install apps and get new experiences on their glasses. Builders finally had a real dev platform. But it only supported glasses with displays.

We quickly grew to thousands of users, and hundreds of them asked for the same thing: camera glasses they could actually build on. Glasses that were unlocked, that didn't stream your view straight to Meta. Glasses that put you in control. Notes, AI, live streaming, recording, take calls, talk to AI.

So we built them. In February we shipped the first 1,000 Mentra Live smart glasses. This week we ship batch 2.

But here's what's interesting. We shipped with a broad feature set, and the user signal was immediate: AI notes. Not streaming. Not general-purpose AI. Notes. Users love it, they're filing bugs on it, they're telling us exactly how to make it better. That's the signal we wanted.

So we've gone all in. Notes is one of the first times I've genuinely gotten sustained value from smart glasses (alongside translation in China!). Expanding your memory while staying present in the moment, capturing what what matters from what you hear and what you see. Less gimmick, more augmentation.

In a world where everyone is racing to build the everything device, focus wins.
