Pete Haas · CTO, WellSaid AI
I’ve spent 30 years building software. The last two decades, I’ve been obsessed with voice.
This site is where I think out loud.
Voice AI isn’t just another interface. It’s the interface.
I’m not interested in hype cycles or press releases. I care about what works, what doesn’t, and what’s coming next. Informed by actually building these systems, not just reading about them.
What I’m building now
WellSaid is the system.
I build cognitive assessment and brain exercise applications for older adults. Voice is the interface. Tapping a tiny screen was never a great answer for the people we serve. A conversation is.
At-home brain health assessment. No referral needed. Results in about a week. wellsaid.ai/learn-more
It’s not about feature adoption or market penetration. It’s about the conversation getting better.
A public build
Genie is a voice-powered guessing game I built in public. LiveKit Agents, Deepgram, gpt-4o-mini, Cartesia Sonic, a lemonslice avatar, Silero VAD.
