Automatic Code Review

Every PR gets reviewed for bugs, security vulnerabilities, and code quality issues — before your team even looks at it.

Living Documentation

TZYLO.md grows with every merge. API changes, breaking changes, architecture decisions — all documented automatically.

Smart Classification

Changes are classified into relevant sections: API changes, database migrations, breaking changes, bug fixes, and more.

Review findings are posted as structured, readable comments directly on your pull requests — clear, actionable, no noise.

Catches common security issues, unsafe patterns, and potential vulnerabilities during review — before they hit production.

Why TZYLO.md

Documentation that writes itself

Engineering teams at startups move fast and skip documentation — until it becomes a problem. Tzylo Synapse captures institutional memory automatically so you never lose context when someone joins or leaves.

Lives in your repo

Versioned with your code. Always in sync. No external platform to maintain.

Searchable

grep, GitHub search, or your IDE — find what changed, when, and why in seconds.

Survives team changes

New engineers have full context from day one. No tribal knowledge lost.

Grows automatically

No manual effort. No stale docs. Every merge adds what matters.

Free during Beta

Stop writing docs.
Start shipping.

Install Tzylo Synapse on your GitHub repositories. Open a PR — it reviews. Merge it — it documents. Zero configuration.
