PhiNote is a private notes app with a real AI built in — and it never leaves your phone. Write your notes like you always do. Then ask PhiNote anything about them: "What did I write about SN2 reactions?" or "Summarize chapter 4." The AI reads your notes and answers instantly, because it's running locally with Qwen3 — not in the cloud. Studying for a test? Tap Quiz Me and PhiNote turns any note into a quiz on the spot. Get scored, see exactly which questions you missed, and review before your next session. Why on-device matters: • Your notes and questions never touch a server • Works with zero internet connection • No accounts required to use the AI • Nothing to leak, nothing to subscribe to just to feel safe Built for iPhone and iPad, with a proper split-view layout on iPad so your notes and chat sit side by side. Free to write, organize, and read your notes. Unlock on-device AI — chat and Quiz Me — with a one-time purchase. Private by design. Smart by default.
