Why Use AI Text Tools?

Every AI chat interface — ChatGPT, Claude, Gemini, Grok, and others — injects hidden technical markers into text during copy operations. These invisible characters include zero-width spaces, byte order marks, HTML data attributes, and other Unicode artifacts that serve internal purposes within the chat UI but become problematic when the text is used elsewhere.

These hidden markers can damage SEO by splitting keywords, break code by inserting invisible characters into variable names and JSON keys, corrupt data in spreadsheets and databases, and trigger AI detection tools. Our suite of free tools lets you detect these markers, understand exactly what's in your text, and clean it with a single click.

All tools run entirely in your browser using client-side JavaScript. No text is ever uploaded, stored, or processed on any server. You can verify this by disconnecting from the internet and using the tools offline — they work exactly the same way.

Compatible with Every AI Tool

Our detection and cleaning tools work with text from every major AI platform. Each tool's interface injects its own combination of hidden markers, and we scan for all known patterns.
