Remove Claude’s formatting from Obsidian
Obsidian discards pasted HTML, so Claude's class names do not survive into an Obsidian note. What does survive is character-level: zero-width characters, exotic spaces, smart quotes and em dashes. Paste as plain text with Ctrl+Shift+V (Cmd+Shift+V), or clean the invisible characters afterwards.

Check my text →What Obsidian keeps
- Obsidian stores notes as Markdown, so HTML class names are converted away or left as literal text.
- Zero-width characters survive into the file and will show up in search and in git diffs if you sync the vault.
The fastest fix
Paste as plain text with Ctrl+Shift+V (Cmd+Shift+V), or clean the invisible characters afterwards.
There is no markup to remove here, so the characters are the whole problem. Zero-width characters, non-breaking and exotic spaces and smart punctuation are text rather than formatting, which is why they survive a route that strips everything else.
How to check it worked
Open the note's .md file directly in a plain-text editor or run it through git diff. Obsidian's editor hides zero-width characters that the raw file contains.
