Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for open-source model APIs. The default in this space.
