What Is Web Captioner? Free Live Captions in Your Browser
Maestra's Web Captioner is a free online live captioning tool that turns speech into real-time captions in your browser, with nothing to download or install. Choose a language (100+ are supported), allow microphone access, and captions appear as people speak. It works for meetings, classes, webinars, live streams, and events on desktop, tablet, or mobile. Live captioning is unlimited and free, and the Pro plan adds live caption translation, higher accuracy, and dubbing with voice cloning. Sessions can be shared with a link or QR code so each attendee reads the captions in their own language, and captions can be sent to OBS, vMix, Zoom, and Microsoft Teams. Web Captioner is a free alternative to the original webcaptioner.com, which has shut down.

Can I use live captions on a PC without installing anything?
Yes. Maestra's live captioner is a website, not an app or browser extension. Open it in a supported browser on your PC, Mac, or laptop, pick a language, and start captioning right away.

Yes. Live captioning is free and unlimited in 100+ languages. Pro is optional and adds live caption translation (with a free trial), higher accuracy, and dubbing with voice cloning.

Can I use live captions for meetings and events?
Yes. You can generate captions in real time for meetings, webinars, and live events, including through OBS, vMix, Zoom, and other integrations.
Does live captioning work in a browser without downloads?
Yes. The live captioning tool runs directly in your browser, so there is no software to install or download. You can start generating real-time captions instantly by selecting a language and capturing audio, making it easy to use on any device with an internet connection.
Can I caption conversations with multiple speakers?

Yes. You can save the audio and live transcript from a session, then fix lines, translate it, or repurpose it as content later.
