README file from
Githubmdfit - Fit Any Markdown
An Obsidian plugin that auto-converts pasted LLM output (ChatGPT / Claude / Gemini) into clean Markdown the moment it lands in a note — no manual cleanup.
Paste from an AI chat and get, instantly:
- Math that renders:
\(...\)→$...$,\[...\]→$$...$$, LaTeX environments wrapped, mid-sentence display math kept on its own lines. - Correct heading levels (ChatGPT's shallow
###headings promoted to#). - Citation noise like
【20†L33-L40】and dangling[1]stripped. - Real Markdown tables and task lists recovered from chat-app HTML.
**Note:**paragraphs turned into Obsidian callouts.- Tidy CJK ↔ Latin spacing, zero-width characters and "Copy code" junk removed.
Code blocks, inline code and math are never touched — conversion is guarded by a protection layer, so examples inside your notes stay byte-identical.
Usage
Just paste into any note (Ctrl+V). The plugin converts the clipboard content
(plain text, or the rich HTML flavor when it carries tables/KaTeX) and inserts
the result. Toggle it at any time with the command
"mdfit: Toggle paste conversion on/off".
