# Setup

Nothing to install to read this guide.

If you want to actually follow it:

- [Obsidian](https://obsidian.md) app (free) — desktop and/or mobile.
- Optional: [Obsidian Web Clipper](https://obsidian.md/clipper) browser extension.
- Optional, for AI wiring: [Claude Code](https://claude.ai/code) or another AI coding agent.
- Optional, for local embeddings: [Ollama](https://ollama.com) running the [nomic-embed-text](https://ollama.com/library/nomic-embed-text) model.

No API keys, no accounts required, no costs beyond the optional paid Obsidian Sync add-on if you choose that sync path.
