About Essay Cleaner
A simple, free tool that strips hidden formatting from AI-generated text so you can paste cleanly into any document.
What it does
When you copy text from ChatGPT, Gemini, Claude, or any other LLM, it carries invisible characters and metadata. Essay Cleaner removes all of that, leaving you with plain, clean text.
