Most transcription services need your file on their servers first. Burncaps runs the speech model inside your own browser, so a confidential recording never leaves your machine. Free, unlimited, and you can verify the claim yourself in about ten seconds.
Transcribe privately, freeLive preview, rendered on this page by the same engine that burns your video.
Press F12 in Chrome or Edge, choose Network, then load your file into the page. Everything a website sends or receives shows up in that list.
You will see the Whisper model download once, about 80 MB from Hugging Face, and then nothing. No upload of your file appears, because none happens.
Once the model has cached, disconnect from the internet and transcribe. It still works, which is only possible if the processing is happening on your own hardware.
If you record client calls, medical or legal discussions, unreleased material, or anything under an NDA, uploading it to a transcription service is a disclosure to a third party, whatever their privacy policy says. Processing that never leaves your device removes the question entirely. There is no server of ours that could be subpoenaed, breached or used for training, because there is no server.

Yes. The model file downloads into your browser once and then executes there using your own processor. You can confirm it by transcribing with your internet disconnected after the first run.
It uses the same Whisper model family that many cloud services are built on. The free tier runs the base model; Pro adds the large-turbo model for harder audio, both running locally.
No. Because there is no server bill to protect, an hour-long recording is fine. Longer files simply take longer to process on your machine.
SRT, VTT, ASS and plain text, or captions burned directly into a new MP4. Everything is generated and saved on your device.
