What Is Croonify and What Does It Do?

Updated

Croonify is an AI karaoke video maker that turns a song file plus its lyrics into a synchronized karaoke video. It is aimed at people who cannot find an existing karaoke version of a song and want to make one themselves, for uses such as parties and events.

The key condition to understand before using it: the recording you upload must contain singing. Croonify states plainly that there must be vocals for the lyrics to synchronize, and that without them it "will NOT do what you want." So this is not a vocal-removal tool — it synchronizes lyrics to a track that already has a voice on it.

How Croonify works

The workflow is a three-step form on the site:

  1. Select Song File — upload audio or video in formats such as .mp3, .m4a, or .mp4. The page labels this field "Vocals Required."
  2. Add Title & Artist — enter the song title and artist. There is a search link to AZLyrics, which suggests the title/artist fields are used to help source or match lyrics.
  3. Paste Lyrics — paste the full lyrics yourself. The page warns: "Do NOT forget lyrics that repeat." If a chorus repeats in the song, the repeated lines need to be present in the text you paste, or the synchronization will not line up.

After submitting, Croonify produces a synchronized karaoke video. The site describes the result as arriving "in minutes," though actual time will depend on song length and processing load.

What you need to bring

Requirement Detail
Song file Audio or video (.mp3, .m4a, .mp4, and similar)
Vocals in the recording Mandatory — no singing means no synchronization
Title and artist Entered manually; AZLyrics search is offered as a helper
Lyrics Pasted by you, including repeated sections

Two practical implications follow from this:

  • You supply the lyrics. Croonify does not appear to fetch them automatically from the title and artist alone — the AZLyrics link is a convenience for finding them, and you still paste the text in.
  • Instrumentals will not work. If you upload a backing track with no vocal, the tool has nothing to align the lyrics against.

Where the song file can come from

The page notes that the iTunes Music store "still works great for downloading DRM-free licensed music," which points to a legitimate route for obtaining a file you can upload. Whatever the source, you are responsible for having the rights to use the recording and lyrics in the way you intend.

When Croonify is the right choice

Use Croonify when:

  • A song has no existing karaoke version and you want one.
  • You already have a recording with vocals and the correct lyrics text.
  • You need a synchronized lyric video for a party, event, or similar setting.

Look elsewhere when:

  • You only have an instrumental and want vocals removed — Croonify does not do that.
  • You expect the tool to find and transcribe lyrics for you without pasting them.
  • You need frame-accurate professional authoring rather than a quick generated video.

Common snags to plan for

  • Missing repeated lyrics. The most likely cause of a video that drifts out of sync is a pasted lyric sheet that omits repeated choruses or verses. Paste the lyrics as they are actually sung, in order.
  • No vocals detected. If you upload a track without singing, Croonify will flag it and ask whether you want to choose another recording. Have a vocal version ready.
  • Format mismatch. Stick to common audio/video containers like .mp3, .m4a, and .mp4 to avoid upload problems.
