Transcription App for Subtitles
🎬 Turn hours of footage into accurate, ready-to-use subtitles — without ever leaving your machine.
Whether you’re subtitling documentaries, films, series, or corporate videos, transcription is the bottleneck between raw footage and a deliverable subtitle file. Transcription App removes that bottleneck entirely — and keeps your media files exactly where they belong: on your machine.

🔒 Everything runs locally on your device. No files are uploaded. No content is stored remotely. No data is shared with third parties. Ever.
🎙️ Unlimited Transcription in 99 Languages
Forget the 2-minute caps and upload limits of browser-based tools. Got a feature-length film or a multi-episode series? Transcribe it in full — start to finish, on your own machine. Working on foreign-language content or multilingual productions? Transcription App supports 99 languages using OpenAI’s state-of-the-art Whisper models, including the newest Large V3 Turbo.
- 🗣️ Automatic speaker diarisation — powered by Pyannote, with over 80% precision, every voice is labelled so you always know who said what
- ⚡ Blazing fast — depending on your hardware, reach transcription speeds of up to ~x20 real-time
- 🔎 Verbatim search across your entire project — find lines, cues, or recurring dialogue in seconds
- 🏷️ Tag and annotate — flag difficult cues, on-screen text, or spotting notes directly inside the transcript
📂 Unlimited Projects — One Place for Every Job
Organise your work the way your subtitling workflow demands:
- 📁 Group episodes, films, and rushes into separate projects with names and descriptions
- 📝 Project-by-project spotting notes
- 🗂️ Keep different clients, languages, and versions cleanly separated
- 📦 Archive and share projects across devices — send a project file to a colleague or client and they can pick up right where you left off
🔒 Private by Design — Your Clients’ Content Deserves It
Unreleased films, pre-broadcast episodes, and confidential client assets are deeply sensitive. NDAs don’t cover cloud servers you don’t control. Unlike typical transcription services that require uploading audio to remote servers with opaque storage practices, Transcription App takes a fundamentally different approach.
- 🛡️ No user accounts tied to your data — it’s an app, not a platform. We just need your email to check your subscription… And that’s it!
- 🧠 Speech recognition and speaker identification are computed entirely on your machine
- ✅ Fully compatible with NDAs, broadcaster embargoes and studio confidentiality requirements
- 🏠 Set custom storage locations — keep media on encrypted drives or your own infrastructure.
This isn’t just a feature. For subtitlers handling embargoed releases, pre-broadcast content, or proprietary material under NDA, local processing is a necessity.
🧑🔬 Built by a Researcher, for Subtitling Professionals
Transcription App is created by Dr. Samuel Haddad-Bacry, a qualitative researcher who built the tool to simplify working with audio and video transcripts. Whether you’re a freelance subtitler with a backlog of episodes or a seasoned professional managing multi-language deliveries — this app adapts to the way you work.
No cloud. No platform. No data you can’t account for.
