Paste the lyrics and upload the song. Every line is timed to the vocals, ready to download as SRT lyrics.
Each line you paste becomes one subtitle. Short lines read best on screen; you can split a long one in the editor later.
AI listens to the vocals, writes the lyrics down and times every word. You can fix any misheard word in the editor afterwards.
Every subtitle file stays here. Uploaded audio is kept for 30 days.
Examples
Full songs with their lyrics pasted in and every line timed to the vocals, shown exactly as they came out. Open one to play it, check the subtitles and download the SRT.
Sign in to upload a song and keep your subtitle files here.
Paste the lyrics, one subtitle per line, and upload the audio: an MP3, WAV, FLAC, M4A or OGG up to 10 MB and 10 minutes.
The vocals are separated from the music and each line is aligned to the moment it's sung. It takes about a minute.
Check the timing against the song, nudge any line, then download the SRT and drop it into your video editor or YouTube.
The SRT times count from the start of the audio you uploaded. Start the song at the beginning of your timeline, or move the caption track by the same amount.
If people should read along while they listen, the lyrics need to land on the beat.
Put SRT lyrics under your YouTube cover so viewers can sing along, without timing every line by hand.
Upload lyric subtitles with the track, in the original language and a translation.
Make CapCut lyrics for a TikTok, Reel or Short: import the SRT and the sung captions are already on the beat.
Give music video subtitles, visualizers and promo clips readable lyrics that match the final mix.
Sign in, upload the song and paste the lyrics, one subtitle per line. Every line is aligned to the vocals in about a minute. Check it against the song in the editor, then choose Download SRT.
Make the SRT here, then open CapCut on desktop or on the web, open the Captions panel and import local captions from the .srt file. Your CapCut lyrics arrive as a caption track you can style, already timed to the vocal. If your phone version doesn't offer caption import, use CapCut on desktop or the web.
In YouTube Studio, open the video, go to Subtitles, pick the language, then choose Add, Upload file and With timing, and select the SRT. Viewers can then turn the lyrics on with the CC button.
Yes. Your line breaks decide the subtitles. To split a long line, use New line before this word in the editor; to join two short ones, merge them. Section labels like [Chorus] on their own line are left out of the subtitles.
The SRT times count from the start of the audio you uploaded. Either start the song at 0:00 on your timeline, or move the whole caption track by the same amount once it's imported.
No. Switch to transcription and the lyrics are written down from the audio first, then timed. Pasting the lyrics is more accurate, because the subtitles then say exactly what you wrote.
