FR-AI / ANALYSISWhy it is worth attention
It combines a free, no-sign-in diagramming tool with a portable open format (OKF) and AI-powered insight generation, making data modeling accessible and collaborative without vendor lock-in.
Who it is for
- Data engineers and analysts
- Data architects and modelers
- Product managers building data products
- BI teams prototyping data marts
Use cases
- Sketching data marts and relationships visually
- Exploring business questions a data model can answer via AI
- Sharing model diagrams via URL (no backend)
- Exporting models to OWOX Data Marts as draft tables
Strengths
- 100% free and anonymous; no sign-in required for design, templates, or sharing
- Field-level ERD view showing columns, keys, and join details
- Open Knowledge Format (OKF) ensures portability via Markdown/YAML files
- AI-generated insight questions from schema metadata only (no row data sent)
Considerations
- Pushing to OWOX requires an OWOX API key (sign-in modal)
- AI question generation needs GEMINI_API_KEY environment variable set on the server
- OWOX API key is stored in browser localStorage, creating XSS risk (mitigated by CSP)

OWOX Model Canvas
Draw a data model on a free, anonymous canvas — then push it into OWOX Data Marts in one click.
▶ Open the live app: model.owox.com — free, no sign-in.
OWOX Model Canvas is a Miro-like canvas for data people. Sketch your data marts (tables, views, SQL or connector outputs) as nodes and joinable relationships as edges, start from ready-made templates, see the business questions a model unlocks (AI), share it as a link, and — when you're ready — push the whole thing into OWOX Data Marts as drafts. The canvas is 100% free and works without an account; an OWOX API key is needed only to Push.
Why use it
- Free & anonymous — design, template, AI-explore and share without signing in.
- Templates for real domains — E-commerce, SaaS, Marketplace, Marketing / Lead-gen, Mobile / Gaming, Finance, Healthcare, plus public datasets (Bitcoin, Stack Overflow).
- Field-level ERD view — see columns, primary keys and join keys, not just boxes.
- Insight Questions (AI) — the business questions a model can answer, generated from schema metadata only (no row-level data leaves your browser).
- Build it with AI — copy a short brief into Claude, ChatGPT or Gemini and it generates an importable model. In-app guide:
/ai-instructions.html. - Shareable links — the whole model travels inside the URL; anyone can open your exact diagram, no backend.
- One-click push to OWOX — turn the diagram into draft Data Marts + joinable relationships.
Open Knowledge Format (OKF) — your model stays portable
The canvas reads and writes 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's human-readable and agent-friendly — people can review it in a pull request and LLMs can author it.
- Author + export, as a pair. Design visually here and Export OKF to get a bundle that round-trips — re-importing restores the model. OWOX publishes real bundles at OWOX/models; this canvas is the visual authoring/export front-end for that same format.
- No lock-in. Be
