Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Bet on this one — the Sparkpage format is genuinely new.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
