Hey Product Hunt 👋
A few weeks ago Google released the Open Knowledge Format (OKF) – a vendor-neutral, markdown way to describe data models for humans and AI agents. Google shipped a read-only viewer; we built the editor.
OWOX Model Canvas lets you draw a data model (or let Claude/Gemini generate it from a sentence), see it as a clean ERD, and export valid OKF — it even opens Google's official sample datasets. It's free, works fully anonymously (no sign-up to try), and it's open source + one-click deployable.
We're a long-time Google Cloud Partner and built this because hand-writing OKF is tedious. Would love your feedback — what would make it your default OKF tool? 🙏
