Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.A-tier. Best for teaching a kid to code in 2026.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
