Built to do the job properly

A tool that is almost right is worse than none, because you trust it.

Your data stays with you

Text, files and passwords are processed on your device and never uploaded. The two tools that need the internet say exactly what they send.

Built to the standard

QR codes are test-scanned before download, JSON keeps big numbers exact, and title case follows the real AP, APA and Chicago rules.

Explained, not just executed

Every tool comes with a written guide to how it works, why things go wrong and how to fix them.
