Rabbit's OS3 AI agent comes to Windows, Mac and Linux without the R1

Rabbit, the startup best known for its R1 pocket assistant, has launched an AI agent that no longer depends on the company's own gadget. According to The Verge, which cites an earlier report from Wired, the new product is an "agentic operating system" called OS3. It runs on Rabbit's cloud infrastructure while carrying out actions directly on a user's Windows, Mac, or Linux computer.

How OS3 works

As The Verge describes it, OS3 is built to act as an autonomous layer on top of the software, files, and services already present on your machines. When you hand it a job, the system decides which connected device, application, document, or AI model it needs to finish the task, instead of requiring you to specify every step yourself.

A single account can link as many as five devices, and users can attach whichever AI models they prefer rather than being tied to one provider. Beyond the desktop, there are several other routes into the agent: a dedicated website, paired messaging apps such as Telegram and iMessage, and, for anyone who still owns one, the R1 handheld.

The R1 era winds down

The Verge is blunt about the device that made Rabbit famous, calling the R1 underwhelming. Company founder Jesse Lyu told Wired that Rabbit has stopped producing the handheld altogether.

That does not mean the startup is abandoning hardware entirely. Wired reports that Rabbit is now working on a "cyberdeck" — a device centered on vibe coding, the practice of building software largely through AI-generated instructions. The cyberdeck will run OS3 and is expected to arrive within a few months, according to the report.

Privacy claims and caveats

Rabbit says OS3 will not store, copy, use, or sell customer data. The company's own fine print carries some qualifications, though. As The Verge notes, Rabbit will still retain your conversations and the memories derived from them on its servers.

There is also a second boundary to the guarantee: any outside AI models connected to OS3 process data under their own privacy policies. In practice, that means Rabbit's promises cover only its part of the pipeline, and users who link third-party models will need to trust those providers as well.

Why it matters

The launch marks a strategic pivot for Rabbit. The company's original pitch rested on a single, inexpensive gadget doing everything through AI; OS3 instead spreads the assistant across whatever computers and chat apps a person already uses. That lowers the barrier to trying Rabbit's technology, since no hardware purchase is involved, and it aligns the startup with the broader industry shift toward agents that operate across applications and operating systems rather than living inside one device or one app.

The privacy caveats will be worth watching as adoption grows. An agent that can read files, open apps, and move between machines needs deep access to a user's digital life, and Rabbit's decision to keep chats and derived memories on its servers leaves open questions about how that trove is managed. For a company whose first product drew criticism for overpromising, OS3 is effectively a second chance — this time judged on how well its agent performs in the environments people already work in, not on the appeal of a novel gadget.
