Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. If you're on Vercel/shadcn, this is cheating.
