What gets cleaned
- Markdown symbols:
**bold**,## headings,---rules, table pipes and code fences are turned into clean text. Lists keep simple “-” or “1.” markers so structure isn’t lost. - Citations:
[1],[^2],【4:0†source】and leftoverturn0search0tokens. - Tracking links:
?utm_source=chatgpt.comand other tracking parameters are stripped from URLs. - Typography: curly quotes become straight quotes, em and en dashes become hyphens, and “…” becomes three dots. Switch any of these off in Fixes if you prefer to keep them.
- Invisible characters: narrow no-break spaces, zero-width spaces and other hidden characters that show up in AI output.
Want to keep the formatting instead?
If you’re pasting into Google Docs, Word, Gmail or Notion, use Copy as rich text. ClepBoard converts the markdown into real headings, bold text, lists, links and tables, so it pastes formatted instead of littered with symbols.
A note on “AI watermarks”
You may have read that ChatGPT hides watermark characters in its answers. There’s no strong evidence that invisible characters in AI text are a deliberate watermark, but they do appear in AI output and they do cause real problems with search, formatting and form fields. ClepBoard shows you exactly what’s there so you can decide. It doesn’t claim to hide text from AI detectors, which analyse wording, not characters.
