Saccade — live web Truth for AI agents

Coming Soon

Saccade turns authorized Chrome and Edge tabs into compact semantic objects and pushes page changes to any connected MCP agent. The browser extension, native host, and runtime stay on your computer.

What Saccade does

Saccade lets an AI agent discover supported controls, read visible page structure, follow meaningful changes, and perform supported actions by object identity. It uses one browser extension package for Chrome and Edge and a local runtime that exposes MCP tools to compatible agents.

Saccade does not use screenshots, Playwright, CDP, or arbitrary coordinate clicks as a fallback. Website permissions apply only to tabs you authorize or tabs the connected agent opens through Saccade.

Saccade reports page state; it does not generate website content. A connected AI agent remains responsible for identifying its own generated output.

Features

Live semantic updates

The extension sends structured objects first, then bounded page changes with stable identity.

Explicit tab authorization

Existing tabs stay Agent Off until you share one. Tabs opened through Saccade are scoped to that agent session.

Local browser bridge

Chrome or Edge connects to a locally installed native host and MCP runtime.

Protected-data boundary

Saccade does not expose passwords, cookies, browser storage, selectors, DOM paths, or arbitrary coordinates.
