Build your own Obsidian with Claude Code

A markdown notes app with backlinks: markdown notes in folders, [[Wiki links]] and backlinks, graph view of linked notes and more.

WeekendA working first version in a day or two

The Claude Code prompt

Build my own take on Obsidian: a markdown notes app with backlinks. Give it an original name, logo, colours and copy, and do not use Obsidian's name, branding or assets.

Version one should have:
- Markdown notes in folders
- [[Wiki links]] and backlinks
- Graph view of linked notes
- Fast search
- Daily notes

The hard part: The graph view. Use a force-directed graph library.

How to build it:
1. Read this folder first. If it is empty, set up Next.js (App Router, TypeScript, Tailwind) with Postgres through Prisma or Supabase, and Supabase Auth or Auth.js for sign-in. Write a short PLAN.md with the data model, screens, third-party services and what you are leaving out of version one.
2. Build the core loop end to end before anything else: markdown notes in folders, working with real data saved to the database.
3. Add the rest of the features one at a time, and seed realistic demo data so every screen looks alive.
4. Keep API keys in environment variables, and put any paid service behind a small interface with a local stub, so the app runs on a fresh machine without accounts.
5. Run it, click through every screen on desktop and mobile widths, fix what breaks, and finish with a summary of what works, what is stubbed and how to deploy it.

Paste it into Claude Code in an empty folder. It plans first, so read PLAN.md and steer before it starts building.

Version one

  • Markdown notes in folders
  • [[Wiki links]] and backlinks
  • Graph view of linked notes
  • Fast search
  • Daily notes

The hard part

The graph view. Use a force-directed graph library.

Make it yours: a niche Obsidian ignores, an original name and brand, and one feature it does badly done well.
