The idea

“Launch HN: Indy (YC S21) – A support app designed for ADHD brains https://www.shimmer.care/indy-redirect Founder's Show HN post: Hi I’m Chris, one of the co-founders of Shimmer, and today we’re launching our new app called Indy (https://www.shimmer.care/indy). Indy is an ADHD app for structured planning, reflection, and self-awareness exercises. Here’s a demo: https://www.youtube.com/watch?v=zDSDxyXv6i4. We started Shimmer in 2022 after my adult ADHD diagnosis, and have shipped several iterations of ADHD support since then (1:1 coaching, web tools, body doubling, and AI-assisted coaching). Across these launches and 80k coaching sessions, we kept running into the same constraint: “knowing what to do” is rarely the problem for people with ADHD. The harder problem is actually doing it consistently over time, especially when attention, motivation, and emotional state fluctuate. That maps to a useful distinction that is explored in the literature (e.g. https://pmc.ncbi.nlm.nih.gov/articles/PMC4589250/): “cool” executive function (future-oriented planning, direction, values) vs. “hot” executive function (in-the-moment emotion, urgency, impulse, overwhelm). Most tools lean hard into managing the latter. Productivity apps push execution, general chatbots give advice, but neither reliably supports the interaction between hot + cold EF across weeks and months. So we built Indy, an AI support system designed to support both. Here’s an overview of how it works: Guided future mapping: users are guided to create a structured map of meaningful past experiences, current priorities, and upcoming future moments. This becomes the foundation for personalization so that everything that they do in the app helps move them closer to these goals Daily + weekly check-ins: users engage in short, low-friction chat flows to set their priorities for the day (most popular use case is brain dumping priorities then having Indy help sort through them). The system does not assume consistency or linear progress, and adapts prompts based on prior behavior rather than enforcing a fixed routine.
