Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Best for teaching a kid to code in 2026.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for model-shopping. I use this for every prototype before committing.
