About inFin
inFin is a completely free, local-first AI voice note app built exclusively for the Apple ecosystem (iPhone, iPad, Mac M1+, Vision Pro). It offers unlimited high-quality recording with real-time transcription and translation (Chinese and English), all processed on-device with offline translation accuracy exceeding 90%. The app also features a web clipping tool for saving articles, images, and links, plus AI-powered text notes with smart formatting. An optional inFin+ module provides AI summarization, Q&A, and writing assistance—all free and ad-free. Data stays encrypted on your device, with export options to PDF, Word, or TXT. Unlike subscription-based rivals like Otter.ai or Notion AI, inFin delivers a rare zero-cost, privacy-first alternative, though it currently supports only two languages and is limited to Apple devices.
Behind the Verdict
inFin is a breath of fresh air in a market cluttered with paid subscriptions. It's genuinely free—zero ads, no recording limits, and all processing stays on-device. For students capturing lectures or creators jotting down ideas on the go, that's a huge win. The web clipping feature is a standout, letting you save articles and images with one tap and tag them neatly. But freedom comes with trade-offs. The on-device transcription, while fast, isn't as accurate as cloud models—expect some errors with specialized vocabulary. You can't edit text during transcription; editing is only possible after export (a feature planned but not yet live). The app is Apple-only, so Windows/Linux users are out of luck. Language support stops at Chinese and English. Versus Otter.ai: Otter offers higher accuracy and team features but costs $16.99/month. inFin is free but less accurate and lacks collaboration. Pick inFin if budget and privacy are your priorities; pick Otter for professional meeting notes. Real-world caveat: The app's free model may not sustain forever—developers hint at optional paid online AI in the future. But for now, it's a generous, no-strings-attached tool. We'd recommend it for personal use, not critical business scenarios.
