About

Interview Transcribe

Features
Read full description

Interview Transcribe transcribes your interview recordings directly on your device. No account, no tracking, no server that ever sees your recordings. Built for documentary work and journalism: • On-device speech recognition via whisper.cpp • Speaker detection with word-level confidence • Full-text search across all projects • Marker tracks for editing and topics • Export to Final Cut Pro, DaVinci Resolve, Premiere, and BWF with timecode • Source protection by default — nothing leaves the device unless you explicitly allow it WHY THIS APP Dictation apps and cloud transcription services aren't built for sensitive documentary material. Interview Transcribe — called abgehört in German — came out of daily practice at bunt.schoen.laut Filmproduktion — a tool that treats source protection as a foundation, not an add-on. UNIVERSAL PURCHASE One purchase, three platforms: iPhone, iPad, and Mac. No subscription, no recurring fees. Restorable via your Apple ID. PROJECT FORMAT Every project is a self-contained .abgehoert bundle. AirDrop it, archive it on an external drive, hand it off to an editing suite — no conversion needed. EXPORT TO YOUR NLE XML for Final Cut Pro 11 with roles and markers. DaVinci Resolve with frame-accurate captions. Premiere markers. EDL. SRT, VTT, plain text. BWF with embedded transcript. FREE MODE You can try Interview Transcribe on up to three projects with five minutes of transcription each, free — plus one project with thirty minutes in one go, so you can take a real interview all the way through. Text export, with an "Interview Transcribe Free" watermark. FULL VERSION One-time purchase — unlocks unlimited projects, unlimited transcription length, every export format, source protection, cross-project search, and the iterative re-run engine. No watermark. PRIVACY Interview Transcribe processes your recordings on your device. There is no server backend, no account, no tracking. The app touches the network in only three places, and you start each of them yourself: the purchase via StoreKit, downloading a larger speech recognition model, and — if you explicitly release a single source for it — cloud transcription or cloud translation. Without that release, no audio leaves your device. SYSTEM REQUIREMENTS iOS 17 or later · iPadOS 17 or later · macOS 15.5 or later · The Mac requires Apple Silicon (M1 or newer); Intel Macs are not supported.
