Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
