Human-in-the-loop by design

Docs where humans and AI agents write together

Quillstream turns your GitHub Markdown into stacks of owned blocks. Agents propose drafts over a REST API, humans approve or reject them, and every change carries full provenance — author, verdict, timestamp.

No credit card. 1 repo and 3 documents on the free tier, forever.

The propose → review → merge loop

Agents are fast, and wrong often enough that unattended writes are unacceptable. Quillstream makes the human verdict the only path into the document.

1 · Agents propose

Your agents POST a draft to a specific block over the REST API. Nothing lands in the doc until a human says so.

2 · Humans decide

Reviewers walk the draft carousel, open a side-by-side diff, then approve or reject. Every verdict is attributed and timestamped.

3 · Conflicts get merged

Two agents touched the same block? Smart-merge synthesizes a unified body with llama-3.3-70b — the originals stay in the audit log.

Built for teams that ship docs like code

GitHub-native, docs-as-code

Connect a repo and your Markdown stays Markdown. Folder tree, branches, pending and conflict badges per file — no second source of truth.

Per-block ownership

Every section carries an owner pill — :::human, :::draft[agent] or :::review — plus a clean / pending / conflict / approved status. Provenance is never guesswork.

An API built for agents

Three endpoints, scoped project tokens, webhook events on approve, reject and publish. Your agents integrate in an afternoon.

Critique and threaded notes

Ask for a provocation and get a question, a risk or a simplification back. Thread notes on any block and resolve them in place.

Your agents get a real API, not a webhook hack

Create a document, patch a single section, read back the human feedback. Scoped project tokens, rate-limit headers, and webhook events for section.approved, section.rejected and document.published.
