Cipher vs Volocal

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.

Talk to an AI assistant that runs entirely on your iPhone. No cloud servers, no API keys, no subscriptions -- just real-time voice conversations powered by on-device intelligence. FULLY PRIVATE, FULLY LOCAL Every word you say stays on your device. Volocal runs three specialized AI models directly on your iPhone's hardware -- nothing is ever sent to the internet. After downloading the models on first launch, you never need a network connection again. REAL-TIME VOICE CONVERSATIONS Speak naturally and hear responses streamed back in real-time. Volocal uses a three-stage pipeline -- Speech-to-Text, Language Model, and Text-to-Speech -- all running simultaneously on different chips inside your phone for smooth, low-latency conversations. INTERRUPT ANYTIME Change your mind mid-sentence? Just start talking. Volocal supports barge-in with hardware echo cancellation, so the microphone stays active even while the assistant is speaking. No need to wait for it to finish. NO SUBSCRIPTIONS, NO API KEYS Volocal is completely free and open source. There are no in-app purchases, no subscriptions, and no hidden costs. Download the models once (~2.3 GB, Wi-Fi recommended) and you're set. HOW IT WORKS Volocal splits the workload across your iPhone's specialized processors: - Speech recognition (Parakeet EOU) runs on the Neural Engine - Language model (Qwen3.5-2B) runs on the GPU via Metal - Text-to-speech (PocketTTS) runs on the Neural Engine This separation means all three models can run at the same time without competing for resources, keeping conversations fluid and responsive. LIGHTWEIGHT Total runtime memory usage is approximately 1.2 GB, well within the limits of modern iPhones. REQUIREMENTS - iOS 17 or later - Physical device only (Neural Engine is not available in the Simulator) - ~2.3 GB of storage for model downloads on first launch Volocal is MIT licensed and open source.
