The short answer
Paste a public link — TikTok, Instagram Reels or post, or a direct MP3/MP4 file URL — and the server matches a 15-second audio snippet against a music database. You get the song's title and artist, and listening links when available.
What counts as a usable link
- Public TikTok videos, including
vm.tiktok.comandvt.tiktok.comshort links. - Public Instagram Reels and posts.
- Direct MP3 or MP4 file URLs — the address of an audio or video file itself.
What is refused
- Douyin, and platforms other than the ones listed above — rejected by design before any request is sent.
tiktok.com/t/…share links.- Anything you cannot link to publicly.
Why a match can fail
Recognition is not magic; it needs music in the snippet. If the 15 seconds you captured are mostly speech, applause or wind, there is nothing for the database to match. Set a start time where the track is clearly audible and try again. Very new or very niche tracks may also be missing from the database.
One snippet per attempt, 15 seconds long, taken from the middle of the media unless you choose a start time. That is deliberate: a short, music-rich sample matches better than a long one full of noise.
Limits
