Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for speed. When latency is the product, start here.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier. Niche but beloved. If you've outgrown Notion, try this.
