Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
