The agentic browser

The browser agents love.

Give Cuiar a task in one sentence, or let Claude Code, Codex or Cursor drive it over MCP. The agent works in your tabs, signs in from your vault and stops when you must decide.

The agent

One sentence in. The work done.

The agent makes a plan, opens tabs, clicks and types. It asks you before it pays, posts or sends. Watch it, or take over at any step.

Watch it work

The real browser, recorded.

Recorded in Cuiar on Linux. The agent works in real tabs, in the workspace the task needs.

  1. 01

    You open the agent

    The agent button in the address bar opens the side panel.

  2. 02

    You ask

    One sentence: which top story has the most comments?

  3. 03

    It reads the page

    The agent reads Hacker News in a tab of the Shopping workspace.

  4. 04

    It answers

    The story with the most comments, with its comment count.

Built in

Everything the work needs.

Ask in the side panel, from the command line, from your AI agent or from your phone. Credits run Cuiar's built-in model, or bring your own Claude or Codex plan.

Vault

Passwords, passkeys and one-time codes. The vault signs the agent in. The agent never sees a secret.

Routines

Run a task on a schedule or when something happens. No limit on any plan.

Odyssey

Deep research. The agent reads many sources, compares them and keeps the citations.

Memory

Cuiar learns which sites you use for which work. Memory stays on your computer.

Approvals

Payments, posts and messages wait for you. Approve on the computer or on your phone.

Cloud hand-off

Move a running task to a cloud browser with its workspace. It continues when your laptop is closed.

Channels

Start and steer a task from your phone, over chat or e-mail.

Developers

Built to be scripted.

Drive Cuiar from the terminal, from your code or from your AI agent. The same tasks, workspaces and routines, everywhere.

Scoped keys
Each API key has its scopes. Revoke a key at any time.
Safe retries
Send an idempotency key with a write, and a retry never runs the task twice.
One spec
The OpenAPI document is made from the server code, so it cannot drift.
Clear errors
Every error has a stable code and a plain sentence.

Install, sign in, give a task

Workspaces

A separate computer for each job.

Keep work, shopping and research apart. The agent works in the workspace that the task names.3 on Free, 15 on Pro.

Own cookies and storage
A sign-in in one workspace never reaches another.
Side by side
Open two workspaces in one window. Their tabs share no data.
Shared extensions
Install an extension once. It works in every workspace.

Privacy

Private by default.

Your browsing, cookies and memories stay on your computer. A workspace goes to our cloud only when you move a task there. The vault is encrypted before it syncs.

How we use dataSecurity

  • Passwords stay out of the model

    The vault signs the agent in. The model gets the user name only.

  • Memory stays on your computer

    See, pin and delete each memory, or turn Memory off.

  • It asks before it acts

    Payments, posts, messages and account changes wait for your yes.

  • No telemetry, no ads

    We never sell your data or train models on it. Google's telemetry is removed from the browser.

Pricing

Start free. Pay when the work grows.

Tasks that your own Claude, Codex or other AI agent runs use no credits. Pay by card or with crypto, and change or stop your plan at any time.

Questions

Asked and answered.

What is a credit?

A credit is a unit of work for Cuiar's built-in model. A short task uses a few credits and a long one uses more. Free has 1,000 credits a month, Pro 4,000 and Team 50,000. Tasks that run on your own Claude, Codex or other AI agent use no credits.

Which AI agents can drive Cuiar?

Any agent that speaks MCP or runs shell commands: for example Claude Code, Codex, Cursor and Gemini. Add the remote MCP server, or let the agent use the cuiar command. Your agent's plan pays for its work.

Does the agent see my passwords?

No. The vault fills the sign-in form; the agent sees only that it is signed in. You choose when the agent may use the vault: always, only while the vault is unlocked, or never. Every use goes into a log.

What is a routine?

A task that runs on a schedule, for example every Monday at 09:00, or every 15 minutes to act on new e-mail. The result comes to you by e-mail. Every plan has unlimited routines.

What is Odyssey?

Odyssey is deep research. The agent makes a plan, reads many sources, compares them and keeps the citations. It is in Pro and Team.

What is cloud hand-off?

Move a running task from your computer to a Cuiar cloud browser. Its workspace goes with it, and the task continues when your computer is off.

What is a workspace?

A workspace keeps its own cookies, storage and sign-ins, like a separate computer. Keep work, shopping and research apart, and tell the agent which workspace a task uses. Tabs of different workspaces never share data, even side by side.

How do I pay?

By card, or with crypto. Yearly billing costs 20% less. Change or stop your plan at any time.

Give it the next task.

Free to start, with unlimited routines. No card.
