What is the AI Text Cleaner?

When you copy text from LLMs like ChatGPT or Claude, or from stubborn PDF documents, it often drags along hidden baggage: zero-width spaces, annoying markdown headers, bold markers, and curly smart quotes that break form fields and databases. This free browser-based utility strips out formatting cruft instantly.

Simple tool designed for my own use, but free for anyone to use.

Features:

Purge Invisible Unicode: Removes zero-width spaces, soft hyphens, and non-breaking spaces.
Strip Markdown: Safely strips structural hash headers and bold/italic wrappers without breaking regular text.
Normalize Quotes: Converts smart curly quotes and em-dashes into clean ASCII equivalents.
