Your Agents Can Now Browse the Web. Securely.
Sigil lets AI agents drive the Chrome you already use, inside deterministic guardrails that decide exactly what they can touch and what they can't.

Works with the AI agents you're already using
Security
Define exactly what your agent can do.
Set deterministic guardrails: block sending email, restrict which sites the agent can touch, lock down sensitive actions across your org. Enforced at the network level, not in the prompt, so they can't be talked around or bypassed.
Efficiency
90% less tokens.
Sigil sends the agent a semantic snapshot of the page, just the elements it needs to act on, instead of a full DOM or screenshot. Smaller context, faster steps, far lower cost per task.
Local execution
Runs on your real Chrome.
Sigil drives the Chrome already on your machine. Your existing sessions, SSO, bookmarks, and extensions are all where the agent works. No cloud sandbox, no shared browser fleet, no copy of company data leaving your laptop.
Install in 60 seconds. Automate anything in your browser.
No new browser. No headless instances. Your real Chrome, your real sessions.
The agent you already use, getting things done...
Done in seconds, while other agents are still apologizing. Whatever agent you use, say "use Sigil" and it runs as the MCP tool in your real browser, inside your guardrails.
