Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Bet on this one — the Sparkpage format is genuinely new.
