# OWOX Model Canvas

> A free, anonymous web canvas to design data models — draw data marts and joinable relationships, explore templates, and export to Open Knowledge Format (OKF). No sign-in needed. Built by OWOX.

OWOX Model Canvas lets data analysts and marketers sketch a data model visually: nodes are data marts (tables, views, SQL or connector outputs), edges are joinable relationships. You can start from ready-made templates, draw your own, get AI-suggested business questions a model unlocks, share a model via a link, and push the model into OWOX Data Marts.

## Key features
- Miro-like canvas to draw data marts and joinable relationships, with an ERD field-level view
- Ready-made templates: E-commerce, SaaS, Marketplace, Marketing / Lead-gen, Mobile / Gaming, Finance, Healthcare, and public datasets (Bitcoin, Stack Overflow)
- Import and export Open Knowledge Format (OKF) — a vendor-neutral markdown bundle for data models
- Shareable model links — the whole model travels inside the URL, no account needed
- Insight Questions (AI) — the business questions a model can answer, generated from schema metadata only
- Build a model with AI — copy a short brief into Claude, ChatGPT or Gemini and import the OKF bundle it returns
- Optional one-click push into OWOX Data Marts (requires an OWOX API key)

## Pricing
Free. The canvas works fully without signing in. An OWOX API key is needed only to push a model into OWOX.

## What is OKF (Open Knowledge Format)
A vendor-neutral way to describe a data model as a folder of Markdown files with YAML frontmatter: one document per data mart, a schema table, and a Joins section for relationships. It is human-readable and agent-friendly — people can review it in a pull request and LLMs can author it. OWOX Model Canvas is the visual authoring/export front-end for this format; OWOX also publishes real OKF bundles at https://github.com/OWOX/models. Because the format is open text, models are portable and never locked in.
