Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
