title: Overview description: AI-related systems: adaptive performance, geo signals, content acquisition.
AI Systems overview
In the Realm context, "AI" means intelligent / adaptive systems, not chatbot. Realm has no conversational persona. Its "intelligence" is implicit:
- Client-side adaptive performance tiers (capability flags driven by device and runtime FPS)
- Vercel edge geo signals driving UI micro-tuning
- Third-party content acquisition (Hitokoto one-liners, tweet archive)
This section is broken down by subsystem. There is no mysterious internal AI model.
