Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for open-source model APIs. The default in this space.
