Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
