Find the invisible character breaking your string

A key that will not match, a CSV column that imports wrong, a JSON file that fails on its first property — often the cause is a character that renders as nothing. Paste the text to get an exact count by type and see each one highlighted in place, then strip them. Nothing is uploaded, which matters when the string came from a production payload.

This tool runs entirely on your device. Nothing you type here is uploaded, logged or stored.

Joiners inside emoji are kept, because removing them would break the emoji.

These characters come from all sorts of places — AI assistants, Word, Google Docs, phone keyboards and copy-paste between apps all insert them. Their presence does not show that text was written by AI, and their absence does not show that it was not. This tool tells you what is in your text and lets you clean it; what that means is your call.

This tool runs entirely in your browser, so the controls above need JavaScript to do anything. The description stays readable either way — nothing here was ever going to be processed on a server.
