Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier. Still early. Manus is more flexible for less money.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.
