Cleaning options

Start with the safe defaults. Optional formatting and advanced rules stay off until you select them.

Recommended cleanup

Safe choices for most pasted text.

Formatting cleanup

Optional rules for turning Markdown-heavy copy into plainer text.

Advanced cleanup

These rules can change emoji, multilingual text, or typography. Use them only when needed and review the result.

Fixed rules, no rewriting

Clean formatting without rewriting your words

Text can look normal while carrying characters you cannot see. Copying from chat apps, PDFs, rich-text editors, or websites can introduce unusual spaces, invisible controls, and Markdown markers. These artifacts can affect wrapping, search, validation, and exact text matching. This cleaner applies only the rules you select and reports what changed.

What this tool cannot promise

This is a formatting cleaner, not an AI detector or authorship verifier. It cannot guarantee detector results or reliably remove model-level text watermarks. It also does not inspect metadata in documents, images, or other files.

Use it to fix formatting, not to conceal authorship or bypass disclosure requirements.

AI provenance is changing

AI companies are adding machine-readable marks

The EU AI Act's transparency rules became applicable on August 2, 2026. The accompanying code covers machine-readable marking and detection for generated text, images, audio, and video where technically feasible.

Providers are taking different approaches. Gemini already uses a model-level text watermark, Anthropic is rolling out text marking for supported Claude models, and OpenAI's public ChatGPT rollout currently covers generated images and supported audio rather than ordinary chat text. That makes careful text handling more important, but formatting cleanup and provenance verification remain separate jobs.

Formatting is not provenance

This cleaner removes selected text artifacts. It cannot verify authorship, inspect file metadata, or promise to remove a model-level watermark.
