HeyAnything

An Android voice trigger that lets you set any custom wake phrase to control your smart home while keeping Gemini or Google Assistant as your default.

Target user

Smart-home owners who want hands-free voice control without giving up their default assistant

Features
  • Custom wake-word setup wizard with on-device training once Android 18 unlocks DSP access
  • Smart home action routing across Home Assistant, Hubitat, SmartThings, and HomeKit bridges
  • Concurrent-listening indicator showing which assistant triggered which action
  • Privacy dashboard listing which processes are listening and what each one can do
Why now

The EU's DMA decision forces Google to expose DSP-backed wake words to third parties, finally unlocking consumer-grade custom wake phrases outside Gemini.
