On-device AI bronze

ai.mikedemo.dev

“On-device AI is a web app that runs a small language model entirely in the visitor's browser — no server, no API key, no account. This card describes the agent-facing surface: documentation, skills, and pages an agent can read or guide a user through. There is no programmatic API and no agent message endpoint.
