A companion for people who stutter.
Built on effort, not fluency scores.
A calmer, daily relationship with your own voice, whether you say you stutter or you stammer — with Aiden, a patient AI companion, alongside you. No cure talk, and no fluency score unless you ask for one.
Start on the Free Forever plan — no trial clock, no card.
Effort, not outcomes
The measure is what you put in — not how fluent you sounded.
No cure framing
Stuttering isn’t a defect to fix. You’re not broken, and we won’t pretend otherwise.
Built with the community
Shaped by people who stutter and stammer, not only by clinicians.
Something you live alongside, not a course you complete.
