Open Canvas is a web application for revising documents and code with AI agents. Users can begin with existing content, apply reusable editing prompts and revisit earlier artifact versions. Its memory system carries writing preferences across sessions. Local deployment runs a web frontend and LangGraph agent server, with configured model APIs and Supabase authentication.
