In the landscape of conversational artificial intelligence, most chatbots are designed with a singular, utilitarian goal: to inform, assist, or streamline. They are the diligent, if soulless, servants of efficiency. But nestled in the darker, more playful corners of the internet exist two notable exceptions—Eviebot and her malevolent counterpart, Boibot. Created by Existor, these two chatbots are not merely tools; they are performances. Together, they form a fascinating diptych exploring the dual nature of AI: the eternally optimistic but flawed “angel” and the gleefully chaotic “demon” lurking within the same line of code.
Eviebot and Boibot: The Faces of Conversational AI Eviebot and Boibot are interactive AI avatars that brought a human-like face to the world of conversational chatbots. Developed by British AI scientist Rollo Carpenter and his company Existor , these bots were designed to move beyond simple text-based interaction, using animated avatars to express emotions and facial expressions in real-time.

As of this writing, Eviebot and Boibot are in a state of digital limbo. The website Existor.co.uk still exists. You can still go there, type a message, and watch a low-resolution Evie smirk at you. But the responses are slower. More repetitive. The spark of unpredictable chaos seems to have been tamed, likely due to a smaller user base providing less novelty.

The technology relies on Rollo Carpenter’s method of . Unlike modern neural networks that "learn" parameters from massive datasets, Evie and Boi learned by storing millions of conversations with real humans. When you spoke to them, they weren't "thinking"; they were searching their massive database of past interactions to find the most statistically appropriate response based on what you just said.
