Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
