"76% chance they text you by 10 AM" - Theo "90% chance he is ghosting you" - Theo "82% chance your neighbor makes $100,000 to $115,000 per year" - Theo Stop spiraling. Start thinking clearly. Just write what's on your mind. Theo asks smart follow-up questions, gathers real evidence, and walks you through a structured analysis so you can see the actual probability of what you're worried about. Most people discover their worst-case scenario is far less likely than they feel. Think of Theo as a brilliant, patient thinking partner — available 24/7 in your pocket. HOW THEO WORKS 1. Journal your worry, decision, or question 2. Theo identifies what you're really asking 3. Answer a few clarifying questions so Theo better understands your situation 4. Theo gathers real-world evidence and weighs it for and against 5. See clear probabilities, not just feelings — then explore the reasoning behind every number WHY THEO WORKS • Evidence over emotion. Theo won't tell you to "think positive." It shows you data — real evidence for and against your worry — so clarity replaces anxiety. • Built on Bayesian reasoning. The same framework used by doctors, scientists, and intelligence analysts to make high-stakes decisions under uncertainty. Theo makes it effortless. • Explore your own thinking. Adjust the evidence yourself with interactive what-if sliders. See how your conclusions shift when your assumptions change. Build critical thinking skills over time. • Sensitivity analysis built in. Theo shows you which pieces of evidence actually matter most — so you know exactly where to focus your attention. • Your private thinking journal. Every session is saved. Revisit past analyses, track how your thinking evolves, and watch your relationship with uncertainty transform. WHO THEO IS FOR • Overthinkers who spiral on "what if" scenarios • Anyone facing a tough decision — career, relationships, health, money • Anybody with curious questions (e.g. "I wonder how much money my neighbor makes?") • People with anxiety who want a concrete, evidence-based alternative to rumination • Students and professionals who want to sharpen their critical thinking • Anyone who's ever lost sleep over something that turned out fine WHAT PEOPLE ARE SAYING "I wrote down something I'd been anxious about for weeks. Theo showed me the actual probability was 4%. I slept through the night for the first time in a month." "It's like having a therapist, a data scientist, and a best friend in one app." "I use Theo before every big decision now. It doesn't tell me what to do — it helps me see clearly so I can decide for myself." Theo Plus unlocks unlimited analyses, full reasoning breakdowns, and interactive what-if exploration so you can think clearly about everything that matters.
