About Expand: Break Limiting Beliefs
You have a belief about yourself that's costing you. You probably know the one. Expand helps you find it, write it down, and test it in real life until it breaks. Most self-help asks you to repeat a nicer sentence until it sticks. That isn't how minds change. Minds change when something you were sure would happen doesn't. Expand is built around that moment. THE METHOD The behavioral experiment is the core tool of cognitive behavioral therapy and one of the most studied techniques in psychology. Name what the old belief predicts. Do the thing. Watch reality disagree. Expand turns that into a loop you can run every day, with a planning step borrowed from research on implementation intentions, shown across nearly a hundred studies to boost follow-through. HOW IT WORKS 1. Discover. A real conversation, not a questionnaire. Bring whatever's bothering you and leave with one sentence you've probably never said out loud. "If I show unfinished work, people will lose respect for me." 2. Audit. List everything that feels like proof. Then take it apart, piece by piece. Fact or interpretation? How old? Whose voice was that, originally? The case against you is usually thinner than it looks. 3. Flip. Write the rival belief. Not an affirmation. Something you could almost believe today. Expand pushes back on moonshots, because a belief that shatters on one lukewarm reply was never worth testing. 4. Remember. Dig up the evidence the old belief made you skip over. It doesn't prove the new belief. It earns it a test. 5. Experiment. Three experiments built around your life, each testing the belief from a different angle. Each is one concrete action you can do within 24 hours. Before you start, you name the safety move you'd normally hide behind and agree to drop it. You write down exactly what the old belief predicts and rate how likely that feels. You pick the moment you'll act. Then you run it, with a few check-ins along the way. 6. Reflect. When the window closes, one question comes first: did the prediction come true? Rate it again. Guided prompts help you make sense of what happened. If the old belief was wrong but a "yes, but" is still nagging at you, that doubt becomes the next experiment. If the run was unclear, you retry. If it went badly, you look at what's underneath. 7. Climb. Every experiment a belief survives moves it up its tracker. Week-long experiments unlock. The skills each one trained, like courage, curiosity, and asking for what you need, level up with them. Once you've worked a few beliefs, Expand checks whether one deeper core belief sits under all of them. WHAT MAKES IT DIFFERENT The experiment decides. Not you, not the app. You're never sent out to collect evidence that you're great. It gets to know you. Everything it learns is listed in Settings, where you can edit or delete any of it. The bad day gets as much care as the good one. An experiment that goes wrong is information about the experiment, not a verdict on you. Try it before you sign up. Tap "Continue without an account" and run the whole thing. Add an email later if you want your progress to follow you. YOUR WORDS STAY YOURS Everything you write is encrypted and locked to your account. It goes to our AI partner only to write your next reply. Never to train models, never to anyone else. No ads, no third-party analytics, no selling data. Export it all as a PDF, or delete every trace, anytime. A NOTE Expand is a tool for examining your own beliefs. It isn't therapy and doesn't treat, diagnose, or heal anything. If you're carrying something heavy, bring a human into it. Expand will always point you to support resources.
What’s new
Version 1.0.4 · Updated October 8, 2026
Finding your belief: • Starter prompts now give you a sentence to finish in your own words. • Not sure how to put it? Pick from a few possible beliefs instead of describing it from scratch. • Expand goes one layer deeper to find what the belief is really saying about you. • "Close, But…" lets you fix the wording before you confirm. • If your evidence points somewhere different, Expand suggests a closer belief. Use it, refine it together, or keep your own. Flipping it: • Your new belief is written in your words. It just has to directly challenge the old one. Experiments: • One option now happens at the real moment it's about, like that meeting on Friday, and you choose when it starts. • Scheduled experiments show when they'll happen, with a reminder beforehand. • Experiments are built from everything you've shared, so they fit your actual life. SMOOTHER EVERYWHERE • Calmer loading screens. • Clearer explanations when you examine your evidence. • Your journey now includes the conversation where you refined your belief.
