Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for model-shopping. I use this for every prototype before committing.A-tier. S-tier if you self-host. The reason open-source image gen matters.
