TabCircuitEARLY ACCESS
YOUR AI, MEET YOUR BROWSER
Bring your AI into the browser you already use.
Real tabs. Familiar workflows. You in control.
Hosted early access Store listings coming soon
01THE BROWSER LAYER
Your pages. Your sessions. Now connected to your AI.
Work in the browser profile you already use, on websites you approve.
01 / THE CONNECTION
Your browser has the context. Your AI has the next step. TabCircuit brings them together—so your agent can read a page, try a flow, and work alongside you on the websites you approve.
Use your logged-in browser. Share a tab, or let your agent open its own.
Read, navigate, click, type and check the result—all through your AI client.
Name your task, save a progress checkpoint, and review an interrupted task before resuming.
02 / A LITTLE HANDS-ON
A task, a tab, and a clear next step.
Try an illustrative workflow below.
Bring the details together. Find the signal.
Make room for your next good idea.
03 / HUMAN AT THE HELM
Automation feels better when the boundaries are clear. Decide where your agent goes, see what it does, and take the wheel whenever you need.
Approve websites individually, for this session or for later. Choose read-only access when the task needs it.
Pause new browser actions from the toolbar. Take over on a shared tab pauses every agent using that tab.
Share only the tabs you choose. Original shared tabs stay open when the agent’s work is finished.
04 / COMPLETE THE CIRCUIT
TabCircuit’s hosted service connects your browser and AI client. No local TabCircuit server to keep running.
Use the hosted extension in the browser you want your agent to use.
Sign in with Google, then use Connect your AI in that browser.
Approve a website, share a tab when needed, and start your task.
Already have the hosted extension? Open TabCircuit in your toolbar and choose Sign in. Your browser stays open while your agent works.

How agent sessions are counted ↗A FEW GOOD QUESTIONS
Yes. Approved pages run in your browser profile, so they can use your existing logins. Agents work in tabs they open or you share. Optional existing-tab discovery helps find relevant tabs on approved websites and is off by default.
Hosted browser builds support Chrome, Brave, Edge, Opera and desktop Firefox, including Developer Edition and Nightly. The hosted setup guides focus on Claude Code and Codex; other clients need remote MCP and compatible authorization support. Safari is not supported. Store listings are not yet available.
No. The hosted extension connects to TabCircuit’s online service. Keep your browser and AI client open. Your client may need a one-time setup command, but no TabCircuit terminal needs to stay running.
Page text, page structure and interaction results from permitted tabs pass through the TabCircuit service to your AI client. Screenshots need their own setting. Your AI provider may retain these results. Hosted builds do not offer arbitrary page-script evaluation or upload the local edition’s shared notes.
With enough available agent slots, you can explicitly share a tab with multiple agents. TabCircuit allows one tab operation at a time and requires a fresh inspection after another agent changes the page. Each agent still needs website access. Take over pauses every agent using that tab.
One AI connection counts once, even when it uses several tabs. Separate Claude sessions or Claude plus Codex count separately. Internal subagents using the same connection count once. Free allows 1 active session and Pro allows up to 10, counted across your browsers and AI clients.
Yes. Pause stops new browser actions. A Needs you handoff lets you complete a step and explicitly resume the requesting agent. An action already underway may finish before Pause takes effect; pausing does not undo completed actions.
SMALL EXTENSION. NEW POSSIBILITIES.
