Supernotes

Supernotes is a note-taking app that organizes ideas, records, tasks, and lists as digital notecards. Cards can include equations, tables, images, checklists, and emojis, with a soft limit of 1,200 characters. Users can tag, nest, and link cards, search them, and explore their connections with graph views. The apps work offline and merge changes and sync when a device reconnects. Cards can be shared for read-only access or collaborative editing in real time. Supernotes imports from Obsidian, Roam Research, Google Keep, Notion, or Markdown, and exports notes as PDF, JSON, or Markdown. It offers an API and lists integrations including Telegram, Raycast, Pipedream, email, SupaSend, and Funnel. The company says notes are encrypted in transit with SSL and at rest with AES-256, and staff do not access note content without express permission during support. The free Starter plan lists 100 cards. Unlimited costs £6 a month, billed as £72 billed annually, and includes unlimited cards, AI Superpowers, full API and integrations, and priority support.
