Character.AI is the entertainment side of AI chat: millions of user-created characters – from study tutors and language partners to fictional personas – each with their own personality, memory and voice. Chats support styles from quick PipSqueak replies to long-form DeepSqueak sessions, and the mobile app drives most of its usage.
The free plan carries ads, slow mode and basic memory. The c.ai+ subscription removes ads, unlocks the best memory and lorebook depth, unlimited top models, chat customisation and premium support – $9.99 monthly, with annual billing around $94.99 per year. It is built for fun and companionship, not document work or coding.
