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.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.A-tier. Best for teaching a kid to code in 2026.
