Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. No reason not to use it if you're on Figma. Not worth switching for.A-tier. Bet on this one — the Sparkpage format is genuinely new.
