Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
