# Hearlark: private audio & video transcription

<!-- cm:hf-upgrade -->
**Free, no sign-up.** How to use:

1. Drop an audio or video file, or record from your mic.
2. Pick a model size and language (or auto-detect).
3. Export TXT, SRT, WebVTT or JSON. The audio never leaves your device.

Drop an audio or video file (or record from your mic) and get a timestamped transcript, **without uploading anything**. OpenAI's Whisper runs inside your browser with [transformers.js](https://huggingface.co/docs/transformers.js): WebGPU when your browser has it, otherwise CPU (WASM).

- **Private by design:** the file is decoded and transcribed on your device. No server, no account, no upload.
- **Exports:** TXT, **SRT subtitles**, WebVTT and JSON (segments with start/end times).
- **99 languages** with auto-detect, plus **translate to English**.
- **Three model sizes:** Tiny (fastest), Base (default), Small (most accurate). Downloaded once, then cached.

Good for interviews, lectures, podcasts, voice memos, meeting recordings and video subtitles when the audio shouldn't leave your computer.

## FAQ
**Why not Otter or TurboScribe?** They are good server-based services, but your file is uploaded and free use is capped: Otter's free Basic plan has 300 minutes a month and 3 lifetime file imports (otter.ai/pricing, Sep 2026); TurboScribe's free plan allows 3 files a day of up to 30 minutes. Hearlark never uploads the audio and has no account or quota.

**How fast is it?** On a plain cloud CPU an 11-second clip took 10.8 s on Tiny and 14.9 s on Base (25 Sep 2026). WebGPU (recent Chrome or Edge) is usually much faster. Long files on CPU take a while, so keep the tab open.

**Is it really free?** Yes. The page and the model files are served by Hugging Face; nothing runs on our servers, so there is nothing to meter.
