Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier for creators training custom looks. B-tier for general use.A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for model-shopping. I use this for every prototype before committing.
