Archii is a personal AI that builds a living model of your mind from data you already own, including ChatGPT exports, Claude exports, notes, drafts, and voice memos. It separates your words from AI assistant responses to learn how you genuinely think, decide, and revise. Users can ask it what they decided and when, have it develop ideas overnight, or run tests to measure how well it knows them. Archii also includes light mental wellness support with guided skills and therapist access built into the same conversation thread. All data stays in your control and can be exported or deleted at any time.
