Offline-first and privacy-first AI apps are gaining momentum on Mac and iOS, as indie developers push on-device processing. Notable examples include oto, TranscribeX, Ezra AI Chat Journal, tetrify, and The Architect [1][2][3][4][5]. A hot topic is speed, with Parakeet delivering dramatic on-device boosts that teams are chasing in local-first apps like TranscribeX [4].
Offline-first transcription - oto — 100% offline; voice never leaves your Mac; 100+ languages with English translation; $30 one-time purchase; global hotkeys; ESL-friendly; no AI writing your words for you [1]. - TranscribeX — macOS app that transcribes locally from audio/video; 100+ languages; supports import/export (TXT, PDF, SRT, VTT); uses fast models and, per updates, Parakeet speed improvements are on the way; free lifetime deals have evolved into promo pricing via Gumroad [4].
Private journaling & Pensieve vibes - Ezra AI Chat Journal — encrypted local storage, offline-first operation, and AI prompts powered by Gemini; offline journaling with context and insights when you reach milestones; syncs to the cloud only when online via Supabase [2]. - The Architect — voice notes become actionable thoughts; privacy is front and center, with conversations about data handling and on-device processing vs API use guiding the conversation [3].
Private knowledge notes, on-device first - tetrify — local-first notes and routines with end-to-end encrypted sync in early beta; export to Markdown/CSV; generous free tier; MacOS/planned cross‑platform expansion [5].
The trend is clear: users want AI that respects their privacy and runs where it matters—on the device itself. Watch this space for more local-first AI on Mac and iOS.
