Should you build your own Capacities?

Organize linked notes as typed objects such as people, books, meetings, and ideas

The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Capacities, organize linked notes as typed objects such as people, books, meetings, and ideas. The hard boundary is object-model polish, mobile capture, sync, calendar integration, and ai features, plus sync, collaboration, and capture polish.

The complete prompt
Build a personal replacement for Capacities 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 linked notes as typed objects such as people, books, meetings, and ideas, 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.

What you will need

Why paying can still make sense

People still pay for Capacities 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.
