Kai's verdictB-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.S-tier in the agent category. The first one I'd give to a non-technical friend.A-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.
