ANNOTATED

ANNOTATED

Capture any page. Highlight any passage. Annotated reads, tags, and summarizes — then gives your agents a signal + context knowledge layer that grows with your use of the web.

Nothing disappears.

How It Works

01

Email or Google. A private library for every account, plus a public feed.

02

Chrome extension: one-click snapshot, or select any text to highlight. Annotated auto-suggests tags.

03

Every page you save becomes signal + context your agents can tap via MCP. Your knowledge layer grows with your use of the web — not a static archive.

Capabilities

Knowledge Layer

Signal + Context for Your Agents

Every capture becomes durable signal your agents can query via MCP — with the context of what you read, when, and why you saved it. The more you use the web, the more your knowledge layer grows. Hybrid BM25 + pgvector with inline citations under the hood.

Highlights

Text-Quote Annotations + AI Tags

W3C Web Annotation Data Model. Highlights survive DOM changes because they anchor to the text itself, not fragile CSS selectors. Annotated suggests tags as you select.

MCP

Agent API

Five tools over MCP: capture, annotate, search, rewatch, get-snapshot. Scoped API keys at /settings/mcp-keys.

Storage

Permanent Snapshots

Full HTML + viewport screenshot, isolated per tenant. A versioned timeline of every URL you capture — so nothing disappears when the source does.
