SIM SIM is a voice-first personal AI assistant that remembers you and follows through — built by Hassan Ali, a solo indie developer, during the hackathon (Oct 26–Nov 4, 2026). You talk to it by name and it answers in voice or text, precisely and honestly: it never invents a fact, a memory, or a reason something failed. It keeps a personal notebook of the durable facts you tell it — people, dates, places, preferences, plans — shows you a "Remembered" chip with Undo when it learns something, and forgets on command. It makes and edits pictures, reads pictures you share, builds PDF documents and small websites, watches your shared screen (eyes only — it can look and answer, never click or type for you), browses the web with citations from pages it actually opened, and holds a "Discussion" where three AI members answer bigger questions independently so you can pick the best one. Everything it can do inside the app runs under a per-group permissions system (Allow / Ask me / Never), with destructive or outside-the-app actions always asking first. SIM SIM is the assistant for one person's real world: a founder in Smyrna, Tennessee who works a cashier/barista job, runs two small products, and needed an assistant that remembers, checks its work, and says "I don't know" instead of guessing.
