TabCircuit

Connect your AI client to your browser. Sign in, approve website access, and stay in control.

TabCircuit connects your AI client to your Chrome browser so it can read and interact with websites you approve, while you stay in control. Install the extension, sign in to TabCircuit, and connect a compatible AI client that supports remote MCP and OAuth sign-in. Keep Chrome open while the agent works. No native host or local relay is required. TabCircuit does not include an AI model or an AI-client subscription. Choose where your agent can work Agents use tabs they open or tabs you explicitly share. Approve a website when access is requested, choose temporary or remembered access, and choose read-only access when interaction is unnecessary. Stop sharing a tab or revoke a website whenever you want. Original tabs remain yours. Existing-tab discovery is off by default. If you enable Use existing tabs on approved websites, an agent can find relevant tabs using short titles, website origins, active state and recent use. This does not approve new websites. See what is happening and take over The control sidebar shows connected agents, their tasks and tabs, pending requests, and recent activity. On controlled webpages, an optional status strip identifies the agent and shows whether it is connected, reading, acting, waiting or paused. A colored cursor and action highlights show its target. New agent tabs are grouped with a task or agent label and color where supported; existing user groups keep their names and colors. Pause an agent from the extension, or use Take over on a page to pause all agents sharing that tab. You can also enable automatic pause when you click or type. Resume agents individually when you are ready. The page indicators are extension controls within the webpage, not browser address-bar controls. Handle tasks with clear stopping points Name tasks, set optional action and active-time limits, and use the repeated-failure pause protection. When an agent needs you to sign in or make a choice, its Needs you handoff pauses work on that tab. After reviewing the website, choose Done—resume; the requesting agent must inspect the page again before continuing. Other agents sharing that tab remain paused until you resume them. When a task is complete, review its agent-reported summary and choose whether to keep its tabs or close only the tabs it created. Original shared tabs and tabs still used by another agent remain open. After restarting an AI client while the browser remains open, you can review an interrupted task and explicitly share its remaining tabs to continue. Previous actions are not replayed automatically. Optional access stays under your control Screenshots require separate permission. File downloads require optional download access and your approval for each requested file. The download tray shows the file, source websites, task, agent and progress. Agents cannot approve their own downloads, open the downloaded files, read their contents or inspect unrelated browser downloads. Advanced browser control is off by default. If you enable it, TabCircuit uses Chrome's debugger input commands for clicks, hovering, typing and key presses on authorized tabs. Chrome displays its debugging notice while attached. You can stop it from that notice or from TabCircuit. Hosted/store builds do not expose arbitrary page-script evaluation. Free and Pro Free supports one active independent agent session. Pro supports up to 15 active sessions across the browsers and AI clients on your account for USD 9 per month or USD 79 per year, including applicable taxes. Both plans include every browser tool and safety control. One session using several tabs counts once; separate client connections count separately. Internal subagents sharing one connection do not automatically count as additional sessions. Explicitly shared tabs coordinate actions and require a new inspection after another agent changes the page. Pro subscriptions use PayPal checkout; no purchase is needed to use Free. Know where your data goes Browser commands, authorized page content and results pass through the TabCircuit hosted service to the AI client you choose. Your client may forward them to its AI provider and retain them under its own policies. Approved pages and enabled screenshots can include private or sensitive information. Website permissions, account authorization and action confirmations are separate controls. Pausing or disconnecting does not undo actions already completed on a website.
