The editor awaits with multiple documents, reading and editing modes, and typographic care that respects your writing.
- III
You ask
Summarise, rewrite or chat with your document using local AI (Gemini Nano). Everything runs on your device — your text never leaves your browser.

You export
Save as portable .md or generate a PDF with selectable text and Atanor's fonts.
