Real-time pitch shifting for YouTube videos

Allows musicians, singers, and learners to change the key of YouTube videos without changing the speed, facilitating practice, transcription, and karaoke.

User opens a YouTube video, clicks the extension icon, adjusts the pitch slider or selects a preset, and the extension applies the pitch shift to the video audio in real-time. Settings are saved per video using local storage.

Target users: Musicians / Singers / Music teachers / Learners practicing by ear

The external host 'pitch-shift--pitch-shift-client-asgi-app.modal.run' is listed in host_permissions but no network requests to it were found in the source code. It may be unused or used in a way not captured by static analysis (e.g., dynamic injection). However, the core functionality appears to be local Web Audio processing.

Monetization

No paid features detected

The extension is free. The keyword 'pro' found in the static analysis is a false positive, appearing in contexts like 'Jungle.prototype' (JavaScript prototype methods) and 'processing' (audio processing), not referring to a paid 'Pro' tier. There are no payment integrations, subscription checks, or upgrade prompts in the code.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is a local audio processing tool for YouTube. It uses Web Audio API and local storage. There is no code for authentication, login, or account creation. The description explicitly states 'Free, no ads, no account'. The external host 'modal.run' is listed in host_permissions but no fetch/axios calls to it are found in the source; processing appears to be local or the host is unused/deprecated. No login UI or logic exists.
