clashtml editor — a live collaborative session with two humans and an AI agent

clashtml --features

html is the document

no proprietary format, no export step. the doc you edit is the markup you ship. paste it anywhere html goes.

native

every edit has an author

provenance tracking pins each change to the human or agent who made it. see who wrote what at a glance, forever.

trust

suggest, comment, resolve

track-changes style suggestions and threaded comments — accept or reject anything, from anyone, including your AI.

review

realtime, conflict-free

CRDT-backed live collaboration. humans and agents type at the same time and nobody clobbers anybody.

collab

Bring your
own agent

point Claude, Codex, or any HTTP-speaking agent at your doc. it reads, edits, suggests, and comments through the same API your browser uses — with its own identity.

agent quickstart

# create a doc your agent can edit

# → and a token for your agent
