A card based notes app with opt in AI for writing and thinking
Beginner API
What is Supernotes?
Supernotes is a card based note taking app with an optional AI layer that handles tedious writing tasks, suggests tags, and points out grammar problems and improvement areas. It runs on Windows, Mac, Linux, iOS and Android, supports Markdown and bi directional links, and targets note takers moving off Notion, OneNote or Logseq.
Supernotes is a note taking app built around small, interlinked cards rather than long documents. Its AI layer, which the team calls AI Superpowers, is an opt in assistant woven into the writing surface. It handles tedious drafting chores, proposes relevant tags for a note, and flags grammatical errors along with passages that could be clearer or stronger. The stated goal is not to write notes for you but to nudge each note toward better quality as you create it. The mechanics follow the card model. Notes are short units that can be linked bi directionally, nested under multiple parents at once, grouped into custom collections, and written in Markdown with LaTeX maths support. Because cards are brief, the AI feedback stays narrow and actionable instead of rewriting whole pages. In day to day use you might draft a meeting note, let the assistant suggest tags so it surfaces later, and accept or reject edit suggestions before publishing the card with a secure share link. Supernotes suits people who think in fragments and want to grow a connected knowledge base: researchers, students, writers, and knowledge workers migrating from Notion, Microsoft OneNote, or Logseq. The site positions it as a speed focused alternative to those tools, with keyboard shortcuts and immediate UI feedback as central selling points. Native apps cover Windows, Mac, Linux, iOS, and Android, and existing Markdown notes can be imported. Against rivals, Supernotes competes on responsiveness and restraint rather than AI volume. There are no autonomous agents or generation pipelines here; the assistant is a quiet editor and organizer. Anyone wanting AI to synthesize whole documents will need to look elsewhere, while those who want a fast card system with a light correctness and tagging layer will find the fit natural.
How do you use Supernotes?
1Check the platform you will use
Supernotes runs on Windows, Mac, Linux, iOS and Android. Review the download page to pick the right build, or use the browser app if you prefer not to install anything.
2Create your account and get the starting cards
Sign up to claim the free allocation of cards, then open the web app to begin. All features are available from the first session, including the AI options.
3Bring existing notes in
If you already keep Markdown notes elsewhere, use the import feature so your existing material becomes cards rather than starting from a blank slate.
4Write your first card with AI help
Draft a short note, then let the assistant suggest tags and flag grammar issues or unclear passages. Accept what is useful and revise the rest before saving.5Organize with links and collections
Connect cards with bi directional links and nest one card under several parents. Group related notes into custom collections so daily work stays visible.
6Share or publish when ready
Use a secure share link to send an individual card to someone else, which keeps collaboration light without exporting the whole workspace.
