Why does Claude formatting break in Notion?

Claude outputs GitHub-Flavored Markdown, but Notion's paste handler doesn't fully support all GFM features. Tables with complex alignment, nested lists, and code blocks without explicit language tags all cause rendering issues. Notion Formatter normalizes the Markdown before pasting.

Yes. Claude's code blocks, markdown artifacts, and formatted responses are all supported. The tool detects missing language tags and adds them automatically for better syntax highlighting.
