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.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for open-source model APIs. The default in this space.
