Tools
Text & developer tools
A growing kit of instant utilities. Everything runs in your browser — nothing leaves your device.
Every tool here is a small, single-purpose utility that does one job well and instantly — no sign-up, no upload, no waiting. Because each one runs as JavaScript in your own browser, whatever you paste never touches a server, which makes them safe even for text you'd rather not send anywhere. The kit covers four everyday needs: reshaping text (case changes, cleaning, counting), generating things (passwords, hashes, QR codes, random values), and encoding or formatting data (Base64, URL, JSON, JWT, CSV). If you catch yourself doing one of these by hand repeatedly, bookmark that specific tool — most people keep two or three pinned in a tab.
