Unicode cleaner 1

Free browser tool for cleaning hidden characters from AI-generated text GPT CLEAN UP is a browser-based text cleaning and AI-assisted writing platform. It removes supported hidden Unicode characters, invisible spaces, soft hyphens, directional controls, HTML attributes, and copied formatting artifacts from text generated or copied from ChatGPT, Claude, Gemini, Grok, Perplexity, and other AI tools. The platform also provides AI humanization workflows for refining AI-assisted writing while preserving its meaning and voice. Core cleaning runs locally in the browser, requires no sign-up, and is designed to improve formatting, compatibility, accessibility, and document usability rather than prove or disprove AI authorship.
