Sundial

Human-agent collaboration—stay in the driver’s seat with Sundial.

Sundial is an agent‑native collaborative editor that lets humans and AI agents work together on documents. Users can hand off tasks to AI agents while retaining control, reviewing and tracking edits, batch reviewing changes across users, agents, files, or time. The platform supports any AI model, including Claude, Code, or the built‑in Sunny agent compatible with 100+ models. It offers real‑time multiplayer features such as live cursors, inline comments, and version history. Sundial provides edit attribution, commit‑based history, and the ability to use any agent without vendor lock‑in. Currently in early‑access beta for researchers and builders.
