I’m building a voice-first second brain for Apple Watch. The idea is simple: capture thoughts instantly from your wrist using the Ultra’s Action button or Siri keywords, without needing your iPhone nearby (using cellular or wi-fi).

Audio is transcribed using EU-based speech-to-text with zero data retention, then turned into searchable notes and summaries.

Basically, I want to capture a thought before I forget it, without pulling out my phone.

If anyone’s interested, I might consider publishing on the app store.
