255 free tools across 10 categories, in a browser, on Windows and on Android. These pages cover installing each app, the things that are different about it, and what does and does not need an account. Nothing here needs a licence key, and there is no paid tier to upgrade to.
Install the Windows app, learn its keyboard shortcuts, and see how updates and uninstalling work.
Install the Android app from Google Play or as an APK, how updates work, and signing in.
Using the tools in a browser: what needs an account, what works offline, and where your files go.
The machine-readable side: an MCP server, a read-only catalog API and agent skills.
232 of the 255 tools finish their work inside the app on your own device, so the file never leaves it. The remaining 23 do send something to a server, and each one is named there along with the reason. That split is the same on the web, on Windows and on Android, because all three run the same tools.
If a step here does not match what you see, or the thing you need is not covered, write to support@toolsmonk.com. Documentation that is out of date is a bug, and it is worth reporting as one.
