Supernotes

Supernotes is a collaborative note-taking app for students and individual knowledge workers who want fast, notecard-based notes that work across web, mobile, and desktop.

Key capabilities include:

• Notecard-first writing with rich content support, including Markdown, LaTeX, images, emojis, tables, and checklists
• Real-time collaboration with sharing, commenting, and publishing links, so others can read without an account
• Organization and retrieval using hierarchy, search, filters, sorting, backlinks, and 2D or 3D graph views
• Cross-device sync plus offline editing for working without a connection

Pricing: Freemium. The Starter plan is free and includes most core features with a limited number of cards (starting at 100, expandable via referrals or achievements). The Unlimited plan adds unrestricted cards, AI Superpowers (for proofreading and organization), full API access, integrations, and priority support (listed at £6/month or $11/month or $99/year, with regional variations). A 4-Year License and student discounts (50–63% off with eligibility) are also available.

What makes it notable is the atomic notecard format combined with fast collaboration and publishing, plus optional AI-assisted editing and organization for users who want more than a basic notes app.
