TaglineSuno's main rival. Often better on instrumental nuance.One API, every model. Pay-as-you-go, no subscriptions.Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.VS Code fork that made AI coding actually work.

Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
