Why Sotto Exists

Most people don’t forget because they have bad memories.

They forget because life moves fast.

Ideas during walks. Recommendations from friends. Lessons learned. Small moments that matter.

The problem isn’t that these things aren’t important. It’s that capturing them usually requires stopping what you’re doing and typing everything out.

Sotto removes that friction.

Press record. Speak naturally. Done.
