Paste your lyrics and the song copyright checker scans them for lines that closely match well known songs, like a famous hook or title line that could cause trouble after you release. You get a uniqueness score from 0 to 100, every flagged phrase with the song it resembles, and a short summary of the risk. It checks the words only, not your recording, so for audio use the Content ID Checker.
You can try it free. New accounts get 6 free credits for 7 days, and each lyric check costs 3 credits, so you can check up to 2 sets of lyrics before paying anything. After that you buy credits as you need them, with no subscription required.
Paste your lyrics into the box (at least 20 characters, a full verse and chorus works best) and press Check Lyrics. In a few seconds you get a uniqueness score, a list of any lines that closely match known songs, and a short summary. The report is saved to your History and you can copy it in one click.
No. This tool checks the words of your song only, not the melody, beat or recording. To see if a recording matches registered songs before you upload it to YouTube, use the Content ID Checker. If you only have the audio, you can pull the words out first with Transcribe Lyrics from Audio and then check them here.
The checker only flags a line when it is a distinctive, recognizable hook or lyric from a specific real song, such as a well known title line or signature chorus. Short everyday phrases that show up in countless songs are not flagged, because simple word overlap is not a copyright risk. The score runs from 0 (a direct copy of a famous song) to 100 (no meaningful overlap found), and each flag is rated Low, Medium or High similarity.
No. It checks whether your lyrics overlap with existing songs, not who or what wrote them. If you want to know whether the vocals in a recording are AI generated, use Detect if Voice is AI Generated.
Yes. Original song lyrics are generally protected by copyright from the moment they are written down or recorded. Reusing a distinctive part of someone else's lyrics without permission can lead to a claim, even if you change a few words. Common phrases and short generic expressions usually are not protected, but distinctive hooks and verses can be.
No. This is an AI check based on broad knowledge of popular music, not a full legal search and not legal advice, and it can miss things. Think of it as a first pass to catch obvious problems before release. For official clearance on a specific song, talk to a music attorney.
Look at the flagged line and the song it resembles. If the overlap is loose or generic, you are probably fine. If it is close and specific, rewrite that part. When your score is under 90 you will see a Revise with AI button, which sends your lyrics and the flags to Write Song Lyrics for a rewrite that keeps your meaning while making the lines more original. The rewrite costs 1 credit.
