Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best for fast prototypes. Competitive with Lovable — try both.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
