Dooder: an AI assistant that hears and speaks on the Apple Watch
The maker built a watch-based assistant with Claude Code as lead developer, with speech recognition and voice running on the Watch itself; in the demo it plans a weekend trip and asks before changing anything.

The full story
Dooder is an AI assistant that lives on the Apple Watch. In the demo it finds the maker's next free weekend from their calendar, searches flights and Airbnbs, and saves the plan to Notion, asking before changing anything. It uses the owner's own Claude API key straight from the Watch over cellular, with no Dooder server in between, and connects to apps through MCP.
Speech recognition (NVIDIA's 110M Parakeet model) and an 8M-parameter neural voice both run on the Watch itself, with a 150,000-word pronunciation dictionary compiled on the iPhone. The whole voice is about 25 MB.
The maker built it with Claude Code as lead developer, agreeing a design before each build and using testers' screenshots as bug reports. It is an early TestFlight beta, and responses usually take 5 to 10 seconds.
