Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.
