LicenseCousin - Royalty-free music finder extension

One click on YouTube to find free-to-use music that sounds like what you're hearing

Problem
Video and podcast creators often love a song but are unsure if they can use it, and don't know where to find similar license-free alternatives. A developer already built a free service, and users want a more convenient path: a one-click lookup right while browsing YouTube.
Solution
A browser extension that, while you listen on YouTube or SoundCloud, extracts audio features and matches five similar-sounding royalty-free tracks with license details and download links. No manual upload or link copying required.
Users
Video creators, podcasters, indie game developers, and social media managers
MVP
Extension reads the current playback page audio; local or lightweight service extracts features; matches a royalty-free library and shows five results; each result shows license type and source link; one-click download or copy license info
Revenue
Free limited daily lookups plus Pro subscription for unlimited matches and batch export; affiliate commissions from royalty-free music platforms
Why now
Short video and indie podcasting are exploding, yet licensing commercial music remains expensive and complex. Audio fingerprinting and feature matching are mature enough to run on personal computers or low-cost services.
