Supernotes

Supernotes is a fast, collaborative note-taking app built around "notecards" instead of long documents. Each note is a compact, richly formatted card, and the whole system is designed for speed, atomic thinking and real-time collaboration — a fresh take on notes that many users praise for its exceptional user experience.

What is Supernotes?

Supernotes replaces the endless document with the notecard: a card holds up to 1,200 characters of rich content — text, equations, tables, images, checklists and emojis — and cards link together into a connected web of ideas. You organize with filters, search and sorting, visualize connections as a 2D or 3D graph, and collaborate on cards in real time.

Who it's for

Supernotes suits a wide range of thinkers: students (including IB, Cambridge, medical and engineering), developers and startups, writers, screenwriters and journalists, researchers, educators, lawyers and therapists. Anyone who prefers concise, connected notes over sprawling documents — and wants them fast and shareable — is a natural fit.

Atomic notes by design

The 1,200-character card isn't a limitation so much as a philosophy. By capping each card, Supernotes nudges you to distill an idea to its essence rather than paste in walls of text — as one user put it, the concise design "forces me to hone my notes into the key points." For studying and thinking, that atomic structure makes notes easier to review, reuse and connect than long, rambling documents.

Connected thinking

Cards gain power when linked. Supernotes supports backlinks between notes and renders those connections as a 2D or 3D graph, so you can literally see how your ideas relate — a boon for researchers and students building a web of knowledge. Combined with strong filters, search and sorting, it stays navigable even as your card collection grows large.

Fast, collaborative and polished

Speed and UX are where Supernotes earns its fans. Keyboard shortcuts make creating and moving between cards near-instant, the interface is clean and quick, and real-time collaboration with commenting lets teams and study groups work on the same cards together. A "Thoughts" collection even helps recover lost notes — small touches that reflect a genuinely well-crafted app.

Yours across every device

Supernotes keeps your cards in sync across desktop and mobile apps, with two dark themes for comfortable late-night work, so your notes are always at hand in the same fast interface. It plays well with your wider workflow too: you can import from existing Markdown notes, export cards to PDF or Markdown, and connect through its API and integrations — so adopting Supernotes doesn't trap your knowledge inside a silo you can't get it out of.

Why choose Supernotes

For anyone who wants note-taking that's fast, concise and connected — and a joy to use — Supernotes is a distinctive choice. Its notecard format encourages sharper thinking, its backlinks and graph reveal how ideas fit together, and its speed, collaboration and polished design make it a compelling alternative to traditional document-based notes, with a free tier to try it out.
