About

BigDayToday

Features

BigDayToday is the AI-powered life-history journal — a memoir that writes itself. Just type it, or say it, the way you'd tell a friend: "I drove that old pickup all through college." No forms, no dropdown menus. The AI pulls out the relevant details from your text and stores them in a simple, private format on your device. Then it gets curious and starts asking leading questions the way a good interviewer would, drawing out the memories you would never think to write down. Come back later and the AI reverses the process. It turns those bare facts back into genuinely meaningful prose describing that chapter of your life — all driven by a configurable "mood" (i.e. funny, nostalgic, dramatic, etc.) that you can specify. Your entries land on parallel timeline threads automatically — Home, Career, Education, Vacations, Health, and more — each one a storyline of your life. Pan through the decades, pinch to zoom, and watch the shape of your life emerge: overlapping chapters, gaps, and all. WHAT YOU CAN DO • Type or speak real sentences — the AI does the structuring • Let it interview you with thoughtful follow-up questions • Read back beautiful prose about each chapter and add more details if you want • Organize your life into color-coded timeline threads • Scroll and zoom a living timeline that spans your whole life • Add people, places, and things and watch their stories overlap PRIVATE BY DESIGN Your history lives on your device. No accounts, no feeds, no followers, no ads, no tracking. To generate prose and follow-up questions, the text of an entry is sent securely to our AI provider (Anthropic) and is not used to train their models. Everything else stays with you. GETTING THE AI The AI features run on Anthropic's Claude and use an API key. New users can request a free setup key at bigdaytoday.app, or add their own Anthropic key in the app. The timeline, threads, and journaling all work with or without AI. BigDayToday works on iPhone and iPad. One sentence is all it takes to begin — the AI will take it from there. Your life, on a timeline.
