One click on the tab you’re watching. No account. No upload.

Tune focus
Raise Focus strength if noise still bleeds through; lower it if speech feels thin.

Under the hood
Enough to understand what happens when you press Start — without the research-paper tour.
Tab audio in
When you start, Voice Refocus listens to the current tab’s audio stream — not your microphone.
Speech-focused cleanup
A local model favors spoken audio and reduces competing background beds, scores, and noise in real time as the tab plays.
Focus strength
The slider sets how aggressively non-speech is pulled down. Higher for busy soundtracks; lower if voices start to thin out.
Stays on your device
The model ships inside the extension and runs in the browser. Audio is not uploaded. Preferences stay in Chrome’s local storage.
Privacy
When you press Start, tab audio is processed locally. No account. No upload.
