Character.AI is a genuinely real, massively-used product — not vaporware — with a huge catalog of user-created chat personas and slick roleplay/voice features that clearly took real engineering effort beyond a thin GPT wrapper.

It's capable and popular, but not spotless, and support/documentation for the platform is sparse relative to its scale.
