The Verdict
Character AI edges ahead with 4/8 features compared to Chai AI's 3/8.

Character AI vs Chai AI: A Deeper Look
Character AI stands out with massive character library and free to use, making it a solid choice for users who prefer a safer, filtered chat environment. Chai AI, on the other hand, brings mobile-first experience and large character library to the table and appeals more to users who prefer a moderated, mainstream experience. With 4/8 features vs 3/8, Character AI has a slight edge in overall capability — but the right choice depends on which features matter most to you.
Neither Character AI nor Chai AI offers unrestricted NSFW chat, AI image generation, persistent memory across sessions, anonymous crypto payments — features that users consistently ask for. Without memory, every conversation starts from scratch and your AI companion never truly knows you. The lack of image generation means you're limited to text-only interactions. These gaps leave room for a platform that takes a more complete approach.
onlyvibe was built to fill exactly these gaps. With 7/8 core features — including NSFW chat, AI image generation, voice conversations, persistent memory, custom characters, and anonymous crypto payments — it combines what Character AI and Chai AI each do well into a single platform. Instead of choosing between Character AI's massive character library and Chai AI's mobile-first experience, onlyvibe gives you both plus the features neither platform offers.
Who Should Choose Which?
Choose Character AI if your priority is voice conversations. Chai AI is a decent pick if you value mobile-first experience.
