Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for model-shopping. I use this for every prototype before committing.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
