Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for model-shopping. I use this for every prototype before committing.
