HUMANS
Built for the human eyes
Read agent output without losing your place. Measure, line height, and heading hierarchy set for ease of reading on backlit displays.
Markdown, read properly
Streamline collaboration with agents over Markdown files.
Or drop a .md file anywhere on this page.
The indexer runs on every commit and writes chunk embeddings to the vector store. Chunk size is fixed at 512 tokens, which the retrieval layer assumes downstream.
Queries are rewritten before search. The rewriter shares a cache with the answer model, so a cold start costs two round trips instead of one.
Offsets are stable only while the source file is unchanged.
Evaluation runs nightly against the golden set. Regressions block the deploy unless a maintainer overrides.
A reading surface for documents written by agents. Markdown is where specs, plans, and agent output already live. Annotate makes it reviewable by people and returnable to the tools that wrote it.

MACHINES
Send back the notes and the lines they attach to, not the whole document. Fewer tokens, fewer guesses about which section you meant.
DEVELOPERS
Pull Markdown files from a repo, review them in place, and open a pull request when a file needs to change. The file never leaves version control.
Share a document with an unlisted link, or require sign-in to open it. Notes from everyone land on the same lines.
Review a spec a teammate wrote, or a draft an agent generated, on the same surface.
Share document
Convert PDFs, Word docs, images, and HTML to Markdown before you send them to an agent.
Same content, fewer tokens.
Conversation
Updated the section to 256 tokens and noted the downstream assumption. Two of your notes are resolved.
Your agent reads the notes itself over MCP — no copying comments into a prompt.
It gets the highlight and the lines it points at.
Repository
PDFs, Word docs, and HTML convert to Markdown. Renders instantly.

The review round that used to take a day of Slack threads now happens in the document itself.

I paste the notes straight back into the agent. It stops guessing which section I meant.

Cycling back my thoughts to the agent became so simple and accurate. The agent stops guessing which section I meant.
