What it does
Notedown fixes the note app dilemma: fast apps lack features, feature-rich apps are slow. Notedown provides a rich markdown editor with image and semantic search support in a <200 kb package for lightning-fast loads. All features (including semantic search) fully work offline as well. Notes are local by default. Enable sync for a note to sync it across any number of devices. Speed of Notepad + intelligence of AI + sync of Notion, without the bloat.
Stop fighting with slow note apps. Notedown opens instantly, works offline, and syncs across devices. Pure markdown without the complexity.
Notion is slow. Obsidian is complicated. Apple Notes can't find anything. Notedown gives you speed, simplicity, and all the features that actually matter. Write markdown on the left, see formatted output on the right. Updates as you type. Find any note in milliseconds. Search by title or meaning with AI-powered semantic search. Fully responsive design. Switch between editor and preview on mobile. Notedown works with standard markdown files. If your current app can export to markdown, you can import it to Notedown. No proprietary formats, no lock-in. Coming soon: One-click import from popular note apps. For now, export your notes as markdown and open them in Notedown. Notedown is built for…from notedown.xyz

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it.
