Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
