About the Service

LiveNote is a free, real-time captioning tool that converts speech to text, making it easy to review meetings, online classes, live streams, and personal notes directly in your browser.

Local caption mode runs models directly in your browser to minimize network transmission. High-accuracy cloud caption mode uses server APIs to get stable results, but sends audio chunks to external APIs.

Built for situations requiring immediate text confirmation, such as accessibility aid, lecture captioning, and meeting transcription. Generated captions are stored in your browser and can be downloaded as TXT files.

Frequently Asked Questions (FAQ)

Is LiveNote really free?

Yes, the core features are free to use. High-accuracy cloud captions and AI summaries may be limited depending on server status and operation costs.

Is it suitable as an accessibility tool for the hearing impaired?

Yes, it helps improve information accessibility by visualising speech in lectures, meetings, and videos. Since AI captions can contain errors, please review them alongside the original audio for critical details.

How is the privacy of caption data protected?

Using Local mode keeps your audio data entirely inside your browser. When using Cloud mode, AI summaries, or Shared View, data may be sent to external APIs for processing.

Where are captions saved?

Generated captions are automatically stored in the History tab using your browser's localStorage. Clearing your browser data may delete them.

Can I caption audio from YouTube or Zoom? (Virtual Cable & Bluetooth/Hearing Aid Setup)

Yes, using a Virtual Audio Cable (VB-Cable) on PC allows you to transcribe computer audio. If you wear bluetooth headphones or hearing aids, follow these steps to hear the audio while generating captions.
