Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.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.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
