Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
