Hermes Obsidian Memory Galaxy: 3D Knowledge Map for AI Agents

Key Takeaways

• Memory Galaxy renders your Obsidian vault as an interactive 3D star map — each note is a star, links between notes draw constellation lines, no setup or export needed
• Recent notes glow brightest so your current focus areas are always visible at a glance; you can orbit, zoom, and click any star to open the note directly
• Hermes can query Obsidian memory by date or topic (e.g. "tell me what I did last month" or "give me keyword ideas based on my Obsidian memory")
• Every agent conversation — Hermes, Claude, or others — automatically writes a new note back to Obsidian, creating a positive feedback loop that makes the galaxy richer over time
• Omi wearable device can take ambient notes throughout the day and export them to Obsidian, feeding the memory galaxy automatically
