Side-by-Side: oTranscribe vs Audio Notes AI

Pricing & Free Tier

oTranscribe, per its own repository (verified September 2026): a free web app, open-source under the MIT license, kept running with donation support — no account and no per-minute price is described in the verified sources. Audio Notes, as of August 2026: free is 60 minutes of lifetime transcription, and Pro includes 10,000 minutes per month, capped at 90 minutes per recording. The honest comparison: oTranscribe wins on price outright (free and open); Audio Notes charges for automation — transcripts written for you, translated, and summarized.

Transcription Method: Manual vs Automatic

oTranscribe assists human transcription: pause, rewind, and fast-forward without leaving the keyboard, a playback-speed slider, rich-text editing, transcripts autosaved to the browser’s localStorage every second, and its own .otr JSON file format. You type every word — slow, private, fully under your control. Audio Notes auto-transcribes server-side with Whisper (large-v3-turbo, large-v3 fallback) in 60+ languages, then summarizes and translates automatically. State the tradeoff plainly: manual for maximum control and zero cost on desktop; automatic on iPhone for speed with draft-tier output on hard audio.

Workflow on iPhone

oTranscribe is a browser-based tool with no iPhone app described in the verified sources; its repository documents YouTube and video file support and offline caching in production builds, with a noted quirk running local copies in Chrome. On iPhone, Audio Notes does the whole job in the app: record up to 90 minutes, import audio (m4a, mp3, wav, caf, aac, aiff, mp4a) and video (mp4, mov, m4v, avi, mkv — audio extracted, workflow in our video-to-text hub), or share audio in from WhatsApp via the iOS share sheet, as covered in the voice-message guide. Every recording is translated and summarized automatically into your preferred language, with per-language setup in the any-language guide and Cantonese specifics in the Cantonese guide.

Choose oTranscribe if you transcribe interviews manually on a desktop and want a free, open tool. Choose Audio Notes if you work on iPhone and want automatic transcripts with translation. The closest neighboring comparisons are Otter and Notta; the alternatives hub keeps score across all eight.
