How it works
-
1. Drop your file
Choose or drag any video or audio file - MP4, MOV, WebM, MP3, WAV, M4A and more.
-
2. Extract audio locally
FFmpeg runs inside your browser and pulls mono 16 kHz audio straight from the file.
-
3. Transcribe with Whisper
The OpenAI Whisper model runs on your device and produces a timestamped transcript.
-
4. Copy, download or refine
Keep the transcript on your device or send it to Driftext to search and summarise it later.
Frequently asked questions
Is my video really private?
Yes. Decoding, audio extraction and transcription all run inside your browser tab. Your file never leaves your device - not even to Driftext servers.
What file formats are supported?
Any video or audio format your browser can read, including MP4, MOV, WebM, MKV, MP3, WAV, M4A, OGG and FLAC.
How accurate is it?
We use the OpenAI Whisper family of models (whisper-tiny by default, upgradable to whisper-base/small/medium/large). Accuracy is on par with the best commercial APIs for most clean audio.
Why do I need to sign up to transcribe?
Signing up is free and instant via an email code. It lets us save your transcript, send it to you, and unlock Driftext features when you are ready for more.
Is there a file-size limit?
There is no server-side limit because nothing is uploaded. Practical limits depend on your device memory - 1-2 hour videos work comfortably on a modern laptop.
