Questions?

What websites does it work on?
YouTube, Spotify, Twitch, Coursera, Khan Academy, Udemy, SoundCloud, Netflix, and Google Podcasts. Any site that plays audio in a Chrome tab, including Zoom and Google Meet in the browser.
Do I need headphones?
No. Context captures audio directly from the browser tab, not your microphone. Headphones or speakers both work fine.
Is my audio recorded or stored?
No. Audio is streamed in real time and discarded immediately after transcription. Nothing is saved.
How do I cancel Pro?
Open the sidebar, go to Settings, and click “Manage Subscription.” This opens the Stripe billing portal where you can cancel. Access continues until the end of your billing period.
