Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-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.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
