Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier in its niche. The only one that actually gets emotion right.S-tier for model-shopping. I use this for every prototype before committing.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
