lisnn

The idea

Which song is in which post?

lisnn listens to the posts on a channel and lists every song it recognises, the second each one starts and stops, and a confidence score. It is made for agencies that look after many brands and need to know what music their clients' videos use. Businesses only.

The workspace

Connect, listen, review.

You sign in to a channel and lisnn hands each public post to a recognition service by its link, so nothing is uploaded and nothing is stored except the results. Every song gets a rights light (licensed, to clarify, change the song) with licensor, reference and expiry date, and a person can mark each post as checked. Results export as CSV. The demo runs the whole workspace in the browser and stores nothing.

Under the surface

One Worker, no stored videos.

A static site and a single Cloudflare Worker with a D1 database in the EU. Platform tokens are encrypted, deleting a channel removes its rows at once, and the marketing site sets no cookies. 10 unit tests pass, and an end-to-end script runs sign-in, sync, recognition and deletion against mocked TikTok and recognition servers.

Status & limits

A demo, not customers.

Recognition runs on ACRCloud and is not perfect: unreleased tracks, live versions and music under a voiceover can go unmatched, and a match can be wrong, which is why every one shows its score and its seconds. lisnn is not legal advice. The screenshots show the demo workspace with made-up channels. Sign-in is not open yet; TikTok is built, YouTube and Instagram appear in the demo. Paid plans, listed from 149 € a month net, start at launch.
