Turn protected study videos into text while you listen, and turn any AI reply into audio — no downloads involved either way.
This listens to the sound your laptop is playing, so it does not need a microphone and works with speakers or earphones. Click Start, choose Entire screen, switch on "Also share system audio", and click Share. Then play the Telegram video. Text appears as the video speaks. Chrome speech needs the internet but your laptop does almost no work, so it keeps up. The offline model runs fully inside this browser but needs a fast laptop. Pick the language the video is spoken in; Chrome cannot detect it by itself.
Each lecture/video you transcribe can be saved separately, so long study material doesn't get overwritten or lost if you close the tab.
Desktop browsers only (Chrome, Edge, Firefox) — this can't run on a phone browser. When you click Start, your browser will ask you what to share: pick your whole screen, a window, or a tab, and tick "Share audio" if offered.
Copy a reply from ChatGPT, Claude, or anywhere else, then paste it below (or tap Paste from clipboard). Uses your device's built-in voices — free, no key, works offline once loaded.
