Solves the problem of low-volume audio in browser tabs (e.g., quiet videos, soft music) by amplifying sound up to 800% without requiring external speakers or system-level changes

User installs extension and clicks the toolbar icon on any tab. Each click cycles volume: 100%→150%→300%→500%→800%→100%. The extension uses tabCapture API to capture the tab's audio stream, routes it through an offscreen document with a Web Audio API GainNode to amplify the signal, and outputs the boosted audio. The icon and badge text indicate the current boost level.

Target users: Users with hearing difficulties / Users watching low-volume web content (videos, music, podcasts) / Users in noisy environments needing extra volume boost

Extension uses offscreen document pattern with tabCapture API which limits direct code tracing but the core audio processing logic is clear in offscreen-core.js and offscreen.js
No popup/options HTML file found - the extension appears to operate purely through toolbar click cycling rather than a UI panel

Monetization

No paid features detected

No premium, subscribe, payment, license, or billing keywords found in source code. All 'pro' keyword hits are false positives: Czech locale 'pro' means 'for' (preposition), and other hits are substrings in minified code. No payment platforms detected. No feature gating or tiered access exists in the code - all volume boost levels (100%→150%→300%→500%→800%) are accessible to all users.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: No login UI, no authentication endpoints, no account creation flow, and no signup/login keywords found in source code. The 'jwt' hit is in verified_contents.json (Chrome extension signed metadata, not user auth). The 'token' in offscreen-utils.js generates a random local UID via crypto.getRandomValues for internal identification, not authentication. The extension works immediately upon installation with no account needed.
