Tandem

Tandem is an AI planning partner that plans your day with you, so you can go to sleep knowing what you actually got done. The problem: most planners are lists you fill in, and most AI assistants wait to be asked. Neither notices when your plan falls apart at 3 PM, and neither helps you understand how much you can realistically do in a day. Tandem is an agent with memory and tools that runs your day alongside you: - Quick-add by text or voice ("DBMS exam Monday, and I want to start reading daily"). The item appears instantly and Tandem plans it in the background. - Smart planning: it breaks events into small sessions in your free time only, around your routine, wake and sleep times, puts the hardest work in your most productive hours and leaves a buffer day before deadlines. It asks for the syllabus before splitting exam prep. - Morning huddle: it asks how your energy is, proposes a realistic plan and pushes back when the day is overloaded. - Check-ins at each task's time: Start (live timer), Push 30 min (the agent replans the rest of the day to fix clashes) or Not today (moves it to tomorrow, no guilt). - Evening wrap-up: a tap-only reflection turns into a chapter-style day card with a lesson for tomorrow, painted in a paper cut-out style starring our otter mascot. Unfinished tasks roll over. - Memory: yesterday's lesson, your routine, habits and history shape tomorrow's plan, with a weekly record and a gentle reflection streak. Tandem gives no health, diet or personality advice. It only plans what you choose to do. Built solo, Indie Developer track, "Build for Your World".
