Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. S-tier if you self-host. The reason open-source image gen matters.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.
