From Avoidance to Confidence
A Real Treatment Program.
Not Another Meditation App.
Day 1: Feel the Difference
Try DAF therapy in your first session. Most people feel an immediate change in their speech. It's not magic — it's neuroscience. Your brain responds to altered auditory feedback by slowing and smoothing your speech patterns.
Days 2-14: Build Your Toolkit
Learn gentle onset, pausing, light contact. Practice conversations with AI. Complete your first real-world challenge. By Day 14, you'll have 5 techniques you can use anywhere — not just in the app.
Days 15-90: Transform
Advanced AI scenarios: job interviews, phone calls, presentations. Feared Words mastery. CBT for speech anxiety. By Day 90, you won't need us anymore. That's the point.
Everything Your SLP Uses.
Available 24/7 in Your Browser.
Audio Lab
You've been told to "just slow down." That's not how it works.
DAF, FAF, Choral Speaking & Metronome — the same clinical tools SLPs use, in your browser. Delayed Auditory Feedback alone reduces stuttering by up to 80% in clinical studies.
Phone Call Simulator
Phone calls are the #1 feared situation for people who stutter.
Practice calling the doctor, ordering takeout, handling customer service — with an AI that responds naturally. Fail safely. Build real confidence.
AI Conversation Practice
You can't practice a job interview with a YouTube video.
Adaptive AI conversations for interviews, dates, meetings, presentations. It listens to you speak, detects your patterns, and adjusts difficulty in real time.
Feared Words Trainer
Everyone has "those words." The ones you rearrange entire sentences to avoid.
Add your personal trigger words. Practice them with gentle onset, cancellation, and pull-out techniques until they lose their power over you.
90-Day Curriculum
Random exercises don't work. You need a structured program.
10 minutes a day. Each session builds on the last — from breathing basics to real-world phone calls. Designed by an SLP, not a product manager.
CBT & Mindfulness
Stuttering is 50% motor, 50% anxiety. Most apps ignore the anxiety.
Thought records to reframe catastrophic thinking. Guided breathing for pre-call anxiety. Prediction testing to prove your fears wrong.
Real-World Challenges
Practicing alone is safe. But fluency lives in the real world.
Daily micro-missions: order at a counter, greet a stranger, make a phone call. Earn XP, build streaks, and prove to yourself it gets easier.
Voice Journal & Analytics
"Am I actually getting better, or does it just feel that way?"
Record yourself daily. AI tracks your fluency rate, speech patterns, and anxiety trends over time. See the proof in your own data.
“I Wish I Had This 10 Years Ago”
Join thousands of people who decided their voice matters.
“I used to let every call go to voicemail. After 3 weeks with the phone simulator, I called my insurance company myself for the first time in years. I cried after.”

“Day 47. My wife noticed the improvement before I did. The daily curriculum keeps me accountable in a way nothing else has.”

“I'm an SLP and this fills a massive gap. My patients practice between sessions and I can see exactly where they're struggling. Game changer for my practice.”

“My name is my hardest word. The Feared Words trainer helped me practice saying "Marcus" until it stopped being terrifying. That alone was worth it.”

This Isn't Positive Thinking.
It's Neuroscience.
80%
fluency improvement with DAF therapy
Delayed Auditory Feedback is one of the most-studied interventions in stuttering research. It changes how your brain processes speech in real time.
70M
people worldwide stutter
You're not broken. Stuttering is a neurological difference affecting 1% of the population. Practice-based treatment works because of neuroplasticity.
10 min
daily practice changes brain structure
fMRI studies show that consistent speech practice literally rewires the neural pathways responsible for fluency. Frequency matters more than duration.

“My Patients Needed a Way to Practice Between Sessions”
I built StutterLab because I watched my clients make incredible progress in our sessions — then come back a week later having lost momentum. They didn't need more willpower. They needed a tool that put clinical-grade practice in their pocket.
Every exercise, every AI conversation prompt, every progression in this curriculum is built on peer-reviewed fluency shaping and stuttering modification research. This isn't a wellness app with a speech theme. It's a treatment program.

Questions You Might Have
Can an app really help with stuttering?
StutterLab uses the same evidence-based techniques (DAF, gentle onset, cancellation, CBT) that SLPs use in clinical sessions. The difference is you can practice them every day, not once a week. Research consistently shows that practice frequency is the #1 predictor of fluency improvement.
Will this replace my speech therapist?
No — and it's not designed to. StutterLab is the practice tool between sessions. Think of it like how physical therapy apps don't replace your PT, but they make sure you do your exercises every day. Many SLPs recommend StutterLab to their patients.
I've tried other apps. They didn't work.
Most speech apps offer breathing exercises and call it therapy. StutterLab has a 90-day clinical curriculum, real-time AI conversation practice, DAF/FAF therapy, feared word desensitization, and CBT — the full toolkit, not a fraction of it.
What if I don't have time?
Each session is 10 minutes. That's shorter than a coffee break. The curriculum is designed for busy professionals who can't spend an hour on speech exercises. Consistency beats duration — 10 minutes daily beats 60 minutes weekly.
Are You a Speech-Language Pathologist?
Your patients need to practice between sessions. StutterLab gives them a structured, evidence-based daily routine — and gives you real-time visibility into their progress. Prescribe exercises, review AI analysis, and track outcomes.
