Cipher turns your voice into organized notes — and now into reminders and calendar events too. 100% free. 100% on-device. Speak freely, AI does the rest. No account. No cloud. No subscription. Open the app and talk. WHAT IT DOES Tap record and speak. Cipher transcribes you in real time, then AI structures everything automatically: • A clean title and short summary • A project tag (Personal, Work, Health, Finance, or your own) • Searchable keywords NEW: AI THAT ACTUALLY DOES THINGS Cipher's AI doesn't just read your notes — it acts on them. • "Remind me to call Mom on Friday" → real reminder, on your iPhone • "Schedule a call with Sarah next Tuesday at 3pm" → calendar event, created • "Find me a free hour this week" → AI checks your calendar and suggests slots • Todos with deadlines can become reminders automatically Every action asks for your confirmation first. Nothing happens behind your back. ASK FLOW — CHAT WITH YOUR NOTES A built-in AI chat that already knows what you've recorded. • Ask anything about your past notes — "what did I say about Q3?" • Summarize a day, a week, or a project in one tap • Brainstorm with an AI that builds on your own ideas PRIVATE BY DESIGN • 100% on-device AI — works offline, on a plane, anywhere • No login, no sign-up, no tracking, no analytics • Your voice and notes never leave your phone • Stored in your iPhone's secure storage FREE FOREVER No subscription. No paywall. No in-app purchases. Use every feature, forever, without paying. CHOOSE YOUR AI Pick from a wide range of free open-source AI models that run entirely on your device — from lightweight options that work on any iPhone to larger, higher-quality models for newer devices. Cipher recommends the right one for your phone. Prefer cloud AI? Bring your own key from OpenAI, Anthropic, Google, Groq, DeepSeek, or OpenRouter. Your key, direct to the provider — no middleman, no markup. SMART TODO EXTRACTION AI catches action items from natural speech — "I need to," "remember to," "should," "have to" — and pulls out deadlines automatically. View every todo across every note in one place. PROJECT ORGANIZATION Notes auto-sort into projects. Create your own. See note counts and todo progress at a glance. WHO IT'S FOR • Students capturing lecture thoughts • Founders dumping ideas between meetings • Writers thinking through drafts out loud • Anyone whose best ideas show up while walking, driving, or in the shower Cipher is for people who think out loud. Capture the thought — let AI do the organizing, and now, the scheduling too.
