User and market recognition
- Character.AI ranked at the top of the US iOS App Store list 6 months after its open beta, with monthly active users exceeding 10 million.
- The average daily active time per user is close to 2 hours, and it has been repeatedly cited by research institutions as "one of the most sticky products for AI applications."

- 2024-08 Reached a non-exclusive license agreement with Google, the founder returned to Google, and the company continued to operate independently.
- Public reports show that young users aged 18-24 account for a significant proportion, and it is one of the AI applications with the highest penetration rate among Generation Z.
Cost advantage

| c.ai+ | $9.99/month | Priority access, faster response, exclusive emoticon beta function | Heavy users / fans |

Summary and Outlook

It forms a clear distinction from the work assistant positioning of ChatGPT and Claude. The follow-up is worth paying attention to: the product rhythm after the Google license agreement in 2024, the protection and supervision of minors towards the depth of immersion in Voice/Scenes/Streams, and the evolution of the overall commercialization path of the AI Companion track.
