AI Paste Cleaner

Paste from ChatGPT, Claude, Gemini or Grok into Obsidian and get clean markdown, automatically.

What it fixes

• Math delimiters: \( x \) becomes $x$ and \[ ... \] becomes a $$ block, so Obsidian renders it.
• Citation markers: removes [1], [1][2], [1, 3] and 【4:0†source】. Markdown links, footnotes ([^1]) and reference definitions are kept.
• Copy-button text: removes leftover Copy code lines and the language label above them.
• Lists: turns •, ◦ and ▪ bullets into markdown lists and 1) into 1..
• Whitespace: removes invisible zero-width characters, converts non-breaking spaces, trims trailing spaces (keeping two-space line breaks) and collapses extra blank lines.
• Optional: remove a trailing "Sources:" list, replace em dashes, straighten curly quotes.

Code blocks and inline code are never changed.

Usage

With Clean on paste on (the default), just paste. If the text has nothing to fix, Obsidian pastes it normally.

Commands:

• Clean selection (or whole note)
• Paste and clean (for when Clean on paste is off)
• Paste without cleaning

Every rule can be turned on or off in Settings → AI Paste Cleaner.
