noa

A Chrome extension for browser automation, powered by Claude Code and Jev. Give Noa a todo list and it works through each task in your own logged-in Chrome (navigating, clicking, typing, uploading), then reports back.

Private by design: Noa runs in your own browser on your machine, and your chats and memory stay there. Sync them between computers end-to-end encrypted, with 12 recovery words only you hold, and Noa's servers keep only ciphertext. See Privacy for the details and for what goes to the AI you pick.

Tasks can repeat on a schedule or run at a set time, which makes Noa a good fit for social media: post, reply and check in on a routine without opening the browser yourself.

You can also run Noa entirely by voice: start tasks, answer its questions and hear results, hands-free. Pick from several voice engines, including OpenAI's latest realtime voice model (gpt-realtime-2.1), a smaller realtime model, Deepgram, or your browser's own voice. Voice runs through a Noa account on a plan with voice (pricing).

Noa can also make phone calls for you: it dials, gets through phone menus and hold music, and talks to whoever answers, while the chat shows every line. You can listen in, take the call over and hand it back. Calls run through a Noa account on a plan with phone calls, on Noa's phone line or your own Twilio account (pricing).

Built for speed: Claude Code plans each task, and Jev, a fast model for picking what to click and type, carries out the single steps, so a run doesn't wait on a full Claude turn for every click.

Use the subscriptions you already have: your Claude plan through Claude Code, your ChatGPT plan through Codex, your own Claude or OpenAI API key, or a model on your own computer, and your own Jev key. Without a Jev key, a signed-in Noa account with usage credit uses Noa's hosted Jev; otherwise Claude does each step itself.

Setup

The quickest way in is to install Noa from the Chrome Web Store, then follow steps 3 and 4. To build it from source instead (requires Chrome, Node.js 22+ and pnpm 10):

1. Build: pnpm install && pnpm build
2. In chrome://extensions, turn on Developer mode, click "Load unpacked" and pick the repo's dist folder.
3. Open the extension's settings, go to AI and pick where the AI comes from: Noa AI (hosted, needs an account), Local Claude Code (your Claude subscription, via a helper app; the page shows the install steps), Local Codex (your ChatGPT plan, via the same helper), the Claude API or the OpenAI API (your own key), or a local model (see below).
4. Sign in to your sites by hand in Chrome, then type a task in the side panel.

A local model (Qwen, Hermes, ...)

Noa can run on a model on your own computer. One command sets it all up:

npx -y noa-local-llm

It installs the helper, OpenCode (the open-source agent the helper runs the model on, with web search, web pages and skills besides Noa's browser tools), Ollama if you have none, and a model (qwen3:8b, or --model) with a context Noa's instructions fit in. Then in Settings > AI pick Local model and click Find models. LM Studio (:1234), llama.cpp (:8080) and vLLM work too: put their address in Settings. Details: packages/local-llm.

How well it works depends on the model: small models often lose track of a multi-step task.

The helper (Local Claude Code)

Local Claude Code needs a small helper that connects Chrome to Claude Code. Settings shows a one-line install command for your system:

• macOS and Linux, in Terminal: curl -fsSL https://noa.bot/helper/install.sh | sh
• Windows, in PowerShell: irm https://noa.bot/helper/install.ps1 | iex

From a source build, run node apps/helper/dist/install.js instead. The command is needed once: when Noa updates, it updates the helper by itself. A helper installed before that (or one whose update failed) shows the command again in Settings; run it and click Re-check. A source build's helper is updated by rebuilding.

Usage

Type a task in the side panel to start it. Every chat, scheduled task and past run shows up as a job: Home groups them by what needs you, what's running and what's coming up; Scheduled lists repeating and timed tasks. How often Noa asks before acting is set under Settings > Permission.

Chrome shows an "is debugging this browser" bar during runs; closing it stops all tasks.

To drive the browser from your own Claude Code:

claude mcp add noa -- node <path-to-repo>/apps/helper/dist/mcp-server.js --attach

An optional account server can queue tasks for the extension to run; see the protocol.

Privacy

Noa works in your own Chrome, with the logins you already have, and keeps your chats, memory and settings in the browser's own storage. Signed out, they never leave your computer.

• End-to-end encrypted sync. Signed in, chats, memory and the pages Noa remembers can sync between your computers. Turn on Settings > Privacy > End-to-end encryption and they are sealed on your computer (AES-256-GCM, with a key from 12 recovery words that never leave your devices) before they are sent: the account server stores only ciphertext and, while encryption is on, refuses anything readable. The code: e2ee.ts (what is sealed) and e2ee-keys.ts (the words and keys).
• Your phone reaches your computer over an end-to-end encrypted, post-quantum hybrid channel (X25519 + ML-KEM-768, then AES-256-GCM); the relay passes messages it cannot read.
• Site logins you save under Settings > Site logins stay encrypted in the browser, behind a passphrase you choose; when a task has to sign in, Noa hands that one login to the AI.

Encryption covers what is stored, not what the AI reads to do the work. To decide each step, Noa sends what is on the page to the AI that runs the task:

• Local Claude Code and the Claude API send it to Anthropic, under your own Claude plan or key.
• A local model keeps it on your computer (unless Jev is on).
• Your own Jev key sends single steps to Jev (TypeSafe) directly.
• Noa AI, Noa's hosted Jev, voice, and memory sync on a plan with the TODO list go through Noa's account server (https://app.noa.bot), only when you are signed in.
