Frequently Asked Questions
Is my audio uploaded to a server?
No. This tool uses **Transformers.js** to run the OpenAI Whisper model entirely **locally in your browser**. Your audio or video files never leave your device, ensuring 100% data privacy.
Can I use this transcriber offline?
Yes! Once you have loaded the page and the AI model (approx. 40MB) for the first time, the tool works completely **offline**. You can disconnect your internet and continue transcribing.
Is this service free?
Yes, KNothing AI Transcriber is **completely free**. There are no limits on the number of files or the length of audio you can process.
Why is there a download when I first use it?
The tool needs to download the **Whisper Quantized Model (~40MB)** to your browser cache. This one-time download allows the AI to run locally on your computer instead of a cloud server.
What file formats are supported?
