AI Karaoke Maker
Croonify is an AI karaoke maker that turns a song file and a set of lyrics into a finished karaoke video. It removes (or reduces) vocals, lines up the lyrics to the singing, and outputs a downloadable video that looks and behaves like the karaoke tracks we all grew up with.
You provide the audio (or video) file, title, artist, and lyrics. Croonify does the rest. If you want to polish the timing, Croonify includes a timing editor so you can nudge lines or words into place and regenerate the video.
How it works
An “AI karaoke maker” is usually doing two jobs:
1) Separate vocals from the instrumental
Croonify performs vocal separation so the main vocal is removed (or reduced) from the song, leaving an instrumental-friendly mix for singing. Croonify also separates main vocals and background vocals independently, because those behave differently and affect karaoke tracks in different ways.
2) Synchronize lyrics to the performance
Croonify analyzes the vocal track and aligns the provided lyrics to the recording. This is why accurate, complete lyrics matter: if a chorus is sung three times, it needs to appear in the lyrics three times.
If you already have a karaoke track (no vocals), Croonify can’t synchronize lyrics to it — it needs the sung vocals to know where the words go.
Standout features
- No subscriptions, no commitments. No account required. Use the service when you need it.
- Regular free access. Croonify is designed so you can try it and use it without feature lockouts.
- Easy timing editor. If a line is early/late, you can adjust timing and regenerate.
- Multiple voices and customizable layouts. Croonify supports multiple voices simultaneously in customizable screen layouts.
- Independent main vs background vocal separation. Useful for songs where harmonies behave differently than lead vocals.
- 1080p rendering. Clean output for modern screens.
- Small file sizes. Typical output is compact (often under 10MB) while staying shareable.
- Background tools. Options to add a background image or video so your karaoke track doesn’t have to look generic.
What you need to provide
Song file
Upload an audio file (or a video file — Croonify will extract the audio). Most common formats work. The service is limited to 6 minute songs.
Accurate lyrics
Croonify’s synchronization is only as good as the lyrics you provide. Remove annotations, ads, and timestamps. If your lyric source only includes the refrain once, expand it so every sung word appears every time it’s sung.
Title and artist
This keeps your generated files organized and makes it easier to find a track later.

FAQ
Is Croonify an AI karaoke maker or a karaoke app?
Croonify is a web-based AI karaoke maker: you upload a song file and lyrics and it generates a karaoke video. There’s no software install required.
Do I need to sign up or subscribe?
No. Croonify is built to work without an account, subscriptions, or commitments.
Why does Croonify need the original song with vocals?
Because lyric synchronization is based on the sung vocal performance. If you upload an existing karaoke track with no singing, there is nothing to align the lyrics to.
Can Croonify handle harmonies or multiple singers?
Yes, to a reasonable degree. Croonify can distinguish between main vocals and harmonies, but some songs (especially choral material) are harder than others.
Does Croonify support my language?
Croonify works with many languages and character sets. If your language doesn’t synchronize well, use the Support link — improving language support is an ongoing effort.
What does Croonify output?
Croonify outputs a karaoke video file with lyrics on screen and vocals removed or reduced. It’s designed to be small and shareable while still looking clean on modern displays.
