See exactly how a structured coaching session works — before you commit to anything.
Pro90D isn't only for fast talkers. If you stutter, stammer, or freeze on certain words, the Smooth Speech System was built for exactly these moments — and you can practice them privately, at your own pace, as often as you need.
Whether it's you or your child, the goal isn't just to "stutter less" — it's to turn what can feel like a liability into one of your greatest assets: your voice. With children, you become the assistant coach, and that partnership is where kids make the most progress.
Pro90D is coaching and daily practice — not medical treatment — built on 14+ years of helping real people who stutter speak with more control and confidence.
Every other AI speech tool is trained on the same generic, public advice. Pro90D's coach is trained on something no one else has — 14+ years and tens of thousands of hours of real coaching: the actual feedback, patterns, and breakthroughs of thousands of clients and students, fused with a neuroscience foundation. It's proprietary to Michael Williams and the Pro90D system. So you're not practicing with a generic bot — you're practicing with the distilled experience of a real coach.
Start free with no credit card — full access to the AI Speech Coach and the complete course for 2 days. These are simply the plans you'd continue on if you love it (that's the only time a card comes in).
