Character.AI is an entertainment app where people chat and tell stories with AI characters, many of them made by other users.
In plain words
Instead of one general assistant, Character.AI offers a huge catalogue of characters, each with its own personality, and lets users invent their own heroes, settings and storylines. It is built for roleplay and interactive fiction rather than getting work done. In what it calls one of its biggest safety decisions, the company stopped letting under-18s have open-ended chats with characters and built its own age estimation model to place people in the right experience.
A quick example
Imagine a student who creates a detective character and a rainy city for it to work in. Other users can find that character, start their own mysteries with it, and build new stories on top of the original idea.
Where you'll meet it
