Show HN: Breatic – Collaborative canvases and documents with an AI agent

Breatic is a real-time collaborative AI workspace where creative teams combine Document Spaces for briefs and scripts with Canvas Spaces for generating and refining media assets, plus an AI agent that works within project context. It is available online and source-available under the Breatic Source-Available License v1.0, which permits individual, private-group and single-organization internal use but prohibits public offerings without separate authorization. Self-hosting uses Docker images with PostgreSQL and Redis, plus a Cloudflare Worker and R2 bucket for uploads, and is not an offline or wholly on-premises installation.
