Works perfectly on BRAVE browser as of 10.08.2025. Full screen working while setting higher sound levels, no glitches whatsoever. Thank you dear Developers, I hope this quality continues and keep up the great work. I've finally found a stable and malware-free Sound Booster. 10 outta 10! Totally recommended!

AI product read

Amplify video volume on any web page up to 600% using the Web Audio API

Users cannot hear video audio clearly due to low source volume or hardware limitations — this extension bypasses system volume caps by applying software gain to video elements

1. Install extension → 2. Navigate to any page with video → 3. Click extension icon → 4. Extension scans for video elements and shows count/duration → 5. User drags slider to desired volume level (up to 600%) → 6. Extension connects each video to a GainNode via MediaElementAudioSourceNode and applies the gain value in real time

Target users: Casual video watchers struggling with low volume / Users with hearing difficulties who need amplified audio / Users watching videos in noisy environments

The external 'pay what you want' URL (soundbooster.store/paywhatyouwant) was not crawled to verify it is purely a donation page vs. a tiered pricing page; however, the extension source contains zero premium gating logic.
No explicit privacy policy content was analyzed beyond the URL provided in store metadata.

Monetization

No paid features detected

All extension functionality (video detection, volume slider up to 600%, gain control) is fully available for free with no gating. There is a voluntary 'Pay what you want' donation link (popup.js line 115-123 → https://soundbooster.store/paywhatyouwant) but it is not tied to any feature unlock, subscription, or license. No payment APIs, no license checks, no premium tier UI exist in the source code.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: No login or authentication mechanism exists anywhere in the extension. The 'session' references in background.js are chrome.storage.session API calls for persisting per-tab volume settings locally — not user account sessions. The extension operates entirely client-side with no account system, no authentication endpoints, and no user identity management.
