Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.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.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
