Text tools

Counting, case conversion and readability, without uploads.

Nothing is uploaded. This tool runs entirely inside your browser tab. Your files and figures stay on your device - we never receive them, so we cannot read, store or lose them.

Your words are not our business

Text tools are where the privacy question is sharpest. People paste drafts, client work, confidential briefs and unpublished writing into these boxes. Every tool here runs in your browser: there is no request carrying your text anywhere, no autosave, and nothing retained when you close the tab.

Counting that matches what you see

The word counter and character counter count graphemes rather than UTF-16 code units, so an emoji counts as one character and an accented letter counts as one regardless of how it was encoded. That sounds like a technicality until a platform rejects a message you were sure fit.

Case conversion for prose and code

The case converter covers both worlds - Title Case and sentence case for writing, camelCase and snake_case for code. The programming conversions split on capital letters as well as separators, so any convention converts to any other in one step.

Working offline

Once loaded, these tools keep working with no connection at all. They are genuinely useful on a plane, on a train, or anywhere the network is unreliable - which is not something a server-side text tool can offer.
