Small, sharp tools that do one thing and tell the truth.

knurl makes deterministic developer utilities — no accounts, no telemetry on your data, no guessing. Each tool runs where you already work: in your browser, and inside ChatGPT, Claude, and Cursor.

Try the Secret Scanner Why knurl

Determinism over guesswork. An AI assistant reads your config and guesses. A knurl tool runs fixed rules — the same input always produces the same result — and on the web it runs entirely in your browser, so the thing you're checking never leaves your machine.

knurl is built to grow. Each new tool lives at its own knurl.tools/<tool> page.

Why knurl

Deterministic

Fixed rules, not a language model. Same input → same output, every time. You can trust the result.

Private by construction

On the web, tools run client-side — your input never leaves the browser. No accounts, no tracking of what you scan.

Runs where you work

The same tool is one click in your browser and one connector in ChatGPT, Claude, or Cursor.
