What the AI text cleaner removes
The small artifacts that make pasted text feel messy.
AI chat windows and rich-text editors can add characters or syntax that look harmless until the text reaches an email, CMS, document, form, or codebase.
Hidden Unicode
Remove unwanted zero-width spaces, word joiners, soft hyphens, byte-order marks, and control characters.
Markdown clutter
Turn headings, emphasis marks, code fences, and Markdown links into readable plain text when you choose that mode.
Broken spacing
Normalize non-standard spaces, remove trailing whitespace, and reduce excess blank lines without flattening paragraphs.
Optional punctuation
Convert smart quotes, long dashes, and ellipses only when the destination requires plain ASCII punctuation.
Same message, cleaner surface
Clean AI-generated text without asking AI to write it again.
The tool follows explicit text rules. It does not paraphrase sentences, invent details, alter tone, or send your draft through another model.

Messages and outreach
Remove stray headings, emphasis marks, and odd spacing before pasting into Gmail or Outlook.
CMS and newsletters

Docs and reports
Keep paragraphs readable when moving drafts between AI tools, Google Docs, Word, and Notion.
Forms and code fields
Remove invisible Unicode and smart punctuation that can interfere with search, validation, JSON, or exact matching.
Clear about the limits
Formatting cleaned.
No detector promises.

- Your text is never uploaded or stored.
- Emoji and joining scripts are protected in Safe clean.
- Visible punctuation changes stay optional.
