Turn SQL into
living documentation.

Paste your CREATE TABLE statements and get beautiful, shareable schema documentation in seconds. No manual formatting. No copy-paste diagrams. Just paste, generate, and share the link with your team.

Supports PostgreSQL, MySQL, SQLite, SQL Server, and Oracle. Export to Markdown or HTML.

Why auto-generate schema docs?

Your schema is the single source of truth. Your documentation should be too.

Instant Documentation

Paste your SQL dump and get formatted docs in under a second. No more hand-writing Notion pages or Confluence tables that go stale the moment someone runs a migration.

5 SQL Dialects

PostgreSQL, MySQL, MariaDB, SQLite, SQL Server, and Oracle. Our custom parser understands each dialect's unique syntax, from SERIAL to IDENTITY to AUTO_INCREMENT.

📤

Export to Markdown or HTML

Download your docs as a Markdown file for GitHub or Notion, or as HTML for your internal wiki. One click, zero formatting headaches.

🔗

Shareable Links

Every generated doc gets a shareable URL. Send it to your team, paste it in a PR description, or embed it in your runbook. The docs stay in sync because they're generated from the SQL itself.

🔍

Complete Structure Detection

Columns, data types, defaults, nullable flags, primary keys, foreign keys, unique constraints, indexes, and CHECK constraints — all extracted and formatted automatically.

🔒

Privacy First

Your SQL never leaves your browser. All parsing happens client-side. Safe for proprietary schemas, financial data models, and healthcare databases.

How it works

Three steps from raw SQL to shareable docs.

1

Export Your Schema

Run pg_dump --schema-only, mysqldump -d, or export from your ORM. Copy the CREATE TABLE statements.

2

Paste & Generate

Paste into the Schema Doc Generator. Choose your dialect. Click Generate. Docs appear instantly with tables, columns, and relationships.

3

Export & Share

Download as Markdown or HTML. Copy the shareable URL. Paste into Slack, Notion, GitHub, or your wiki. Done in 30 seconds.
