Configure local settings
If your workflow needs AI processing, choose a provider, save the local settings, and run the built-in connection test.
What happens after install
The extension is ready to work inside YouTube once the browser finishes the install and the page is refreshed.
- Open a YouTube video and launch TubeCaps from the toolbar or page UI
- Capture the transcript and move straight into summary or rewrite work
- Keep provider, model, and language preferences in local browser storage
Troubleshooting the first run
If the first open does not look right, the issue is usually install state, page refresh, or local provider settings.
- If the store button is unavailable, retry from a Chrome profile where extension installs are enabled
- If the UI does not appear, refresh the current YouTube tab after the install finishes
- If AI calls fail, recheck the saved provider settings and connection test result
Install first. Configure only what you need.
TubeCaps is easiest to evaluate from the live extension flow on an actual YouTube video page.
