Opa — Personal AI Knowledge Assistant

Talk to your phone. Build a knowledge graph that remembers everything.

Opa wires together Claude, Obsidian, and iCloud into a personal AI assistant with persistent memory — using tools you already pay for. No new subscriptions. No servers. No app to install.

Ask Claude to plan a trip, brainstorm ideas, or manage a project. Every conversation builds a searchable, linked knowledge graph in your Obsidian vault, synced across your devices via iCloud.

What you get:

• Automated setup script
• Step-by-step guide with screenshots
• Troubleshooting tips & best practices
• Future updates included

Requirements: macOS · Claude Pro subscription · Obsidian (free) · iCloud

Built by Scott Hawley — physicist, ML researcher, and musician. I built this for myself; it worked so well I'm sharing it.
