AI tools output markdown. OneNote doesn’t understand it. We bridge the gap instantly.

You copy a response from ChatGPT or Claude, paste it into OneNote, and every formatting symbol shows up raw. Hash marks, asterisks, backticks, pipe characters all displayed as plain text.

Questions?
Yes. All six heading levels (H1–H6) render with distinct styling and map to OneNote’s built-in heading styles. This is better than Google Docs, which only supports H1–H3.
Tables render with borders, a blue header row with white text, and proper cell structure. Formatting inside cells (bold, italic, code, links) is preserved.
OneNote doesn’t support the HTML blockquote element or CSS border-left on pasted content. This is a OneNote limitation. Blockquotes render as italic gray text instead.
Yes. Code blocks render in Consolas monospace font with a light gray background and correct indentation. Each code block is visually separate, unlike Word where they can merge.
No. Unmarkdown™ runs 100% in your browser. Your markdown is converted locally and copied to your clipboard. Nothing is ever sent to any server.
Yes. Any tool that outputs markdown works: ChatGPT, Claude, Gemini, Copilot, and more. Just paste the markdown into Unmarkdown™, click “OneNote”, and paste the result.
