Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier for creators training custom looks. B-tier for general use.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
