Can AI replace Supernotes?

The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Supernotes, capture small linked cards, tag them, and review or share focused collections. The hard boundary is real-time collaboration, mobile polish, sync, and card-based workflow refinement, plus sync, collaboration, and capture polish.

StarterFreeFreeStarts with 100 kept cards; +20 cards per successful referral; cards have a 1,200-character soft limit.
Unlimited$10.82$8.12/moUnlimited cards; full API and integrations; AI features; priority support on yearly billing.
Unlimited 4-Year licence——Unlimited creation for 4 years; after expiry, existing cards remain readable, editable and shareable, but no new cards can be created.

Hidden costs: App Store/Play Store prices and taxes can differ by region; student pricing is 50% off yearly or 63% off the 4-year licence; new-card creation stops when a 4-year licence expires unless renewed

02Could AI build it for you?

The core job: Capture small linked note cards, tag them into focused collections, search them instantly, surface backlinks, and export a normal Markdown folder.

What a working version needs:

  • macOS, Windows, or Linux
  • local folder access
  • optional sync folder chosen by the user

Editorial comparison targets the Unlimited plan and a personal local knowledge base DIY substitute. Recheck price before merge.

03What you'd give up

  • real-time collaboration, mobile polish, sync, and card-based workflow refinement
  • frictionless mobile capture
  • real-time team editing
  • hosted publishing
  • proprietary AI memory

People still pay for Supernotes because people keep paying when the note system is trusted across every device and disappears into their daily capture habits. The recurring cost buys file watching, conflict handling, indexing, mobile apps, encryption, backups, and migrations, not just the visible interface.

05The build prompt

Paste this into an AI coding tool (such as Claude, ChatGPT, Lovable or Replit) to build your own version.

prompt.txt
Build a personal replacement for Supernotes in an empty repository.
Use Tauri 2, React, TypeScript, SQLite, and Markdown files as the source of truth; do not offer alternative stacks.
The core loop is: capture small linked note cards, tag them into focused collections, search them instantly, surface backlinks, and export a normal Markdown folder.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Store one Markdown file per note and a small SQLite index that can be rebuilt at any time.
Support wiki links, tags, backlinks, daily notes, pinned notes, and full-text search.
Add a fast command palette and keyboard-first create, rename, move, and link actions.
Render Markdown with task lists, code blocks, tables, and local image attachments.
Detect external file changes and show a safe conflict-resolution view.
Provide full-folder export, import, and an index-rebuild command.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Deliberately leave out proprietary sync servers.
Deliberately leave out real-time multiplayer documents.
Deliberately leave out a plugin marketplace and hosted public sites.
Finish by running the tests and listing the exact commands used.
