Frequently Asked Questions

Creating a Song
- First, go to Kai by clicking the easel icon anywhere in your workspace or studio or click here.
- Within the chat you can type out what kind of sound or song you want the AI to generate.
- There’s no way for the AI to generate a song of a specific length in seconds at this time as the length of the song is actually determined by the lyrics that it generates.
- If you want a longer song, you should prompt that you want "more lyrics" or a “longer song”. If you want a short song, prompt that you want only a "few lyrics" or a "shorter song".
- Once the generation is to your liking you can download it directly within Kai chat via the download button or you can edit in Kapwing to add in images and videos to the song.
