A few days ago, I saw the @Kindred_AI article organized by the Supers big shot. I think it was very well written. For details, please see the attached image. However, if you want to truly implement it, some practical considerations are still necessary. 1⃣ Does the product really become a daily habit? Mainly look at 1D / 7D / 30D retention data, DAU/MAU accumulated messages, daily interaction frequency, and active opening ratio. 2⃣ Does the AI role understand you more and more as you use it?
