Supernotes · London, United Kingdom · founded 2018
What it is
Supernotes is a note-taking app that organizes ideas, records, tasks, and lists as digital notecards. Cards can hold equations, tables, images, checklists, and emojis, with a 1200-character soft limit. Tag, nest, and link cards to organize them, then search or view their connections in graph views. The apps work offline and merge changes and sync when a device reconnects. Cards can be shared as read-only or edited collaboratively in real time. Supernotes imports from Obsidian, Roam Research, Google Keep, Notion, and Markdown, and exports notes as PDF, JSON, or Markdown. Listed integrations include Telegram, Raycast, Pipedream, email, SupaSend, and Funnel; an API is also available. The maker 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. Supernotes is available on web, Windows, macOS, Linux, iOS, and Android. Starter lists 100 cards, while Unlimited costs £6 a month, billed £72 annually, and includes unlimited cards, AI Superpowers, full API and integrations, and priority support.
