Character.ai (also known as c.ai or Character AI) is a neural language model chatbot service that can generate human-like text responses and participate in contextual conversation. Constructed by previous developers of Google's LaMDA, Noam Shazeer and Daniel De Freitas, the beta model was made available to use by the public in September 2022.[2][3] The beta model has since been retired on September 24, 2024, and can no longer be used.[4]

On May 11, 2023, character.ai announced character.ai+, a opt-in subscription plan marketed as $9.99 a month, that was marketed as including features such as skipping waiting rooms, fast messaging and responses, and access to a exclusion channel with faster support.[5]

This decision sparked anger and discontent within the community as waiting rooms and slow responses from the characters were originally announced as a temporary fix to server load issues,[6] only to now be shown as a permanent feature that could only be avoided by paying for character.ai+.

Users can create "characters", craft their "personalities", set specific parameters, and then publish them to the community for others to chat with. Many characters may be based on fictional media sources or celebrities, while others are completely original, some being made with certain goals in mind such as assisting with creative writing or being a text-based adventure game.[7][3]

In May 2023, a mobile app was released for both the Apple App Store and Google Play Store, which had over 1.7 million downloads within its first week.[8]

History

[edit]

Character.ai was established in November 2021.[1] The company's co-founders, Noam Shazeer and Daniel De Freitas, were both engineers from Google.[9] While at Google, the co-founders both worked on AI-related projects: Shazeer was a lead author on a paper that Business Insider reported in April 2023 "has been widely cited as key to today's chatbots",[10] and De Freitas was the lead designer of an experimental AI at Google initially called Meena, which would later become known as LaMDA.[10]

Character.ai raised $43 million in seed funding at the time of its initial foundation in 2021.[11]

The first beta version of Character.ai's service was made available to the public in September 2022.[9] The Washington Post reported in October 2022 that the site had "logged hundreds of thousands of user interactions in its first three weeks of beta-testing".[9] It allowed users to create their own new characters, and to play text-adventure game scenarios where users navigate scenarios described and managed by the chatbot characters.[9]

Following a $150 million funding round in March 2023, Character.ai became valued at approximately $1 billion.[11]

As of January 2024, the site had 3.5 million daily visitors, with the vast majority of them being 16 to 30 years old.[12]

In 2024, Google hired Noam Shazeer, the CEO of Character.ai, and entered into a non-exclusive agreement to use Character.ai's technology.[13]

Software

Character.ai's primary service is to provide users with the ability to have conversations with character AI chatbots that are based on fictional characters or real people (living or deceased).[14] The responses of these characters use data the chatbots gather from the internet about a person.[15] In addition to the chat feature, users can play text-adventure games where characters guide them through scenarios.[14] The company also provides a service that allows multiple users and AI chatbot characters to converse together at once in a single chat room.[16]

Character "personalities" are designed via descriptions from the point of view of the character and its greeting message, and further molded from conversations made into examples, giving its messages a star rating and modification to fit the precise dialect and identity the user desires.[17]

When a character sends back a response, the user can rate the response from 1 to 4 stars. The rating predominantly affects the specific character, but also affects the behavioral selection as a whole.[18]

Controversies

[edit]

In May 2024, the family of Michael Schumacher won a legal suit against the magazine Die Aktuelle after it published an article which claimed to be an interview with the former Formula One driver but which was actually generated using Character.AI.[19]

In October 2024, the Washington Post reported that Character.AI had removed a chatbot which appeared to have been based on Jennifer Ann Crecente, a person who had been murdered by her ex-boyfriend in 2006. The company had been alerted to the character by the deceased girl's father.[20] Similar reports from The Daily Telegraph in the United Kingdom noted that the company had also been prompted to remove chatbots based on Brianna Ghey, a 16-year-old transgender girl murdered in 2023, and Molly Russell, a 14-year-old suicide victim.[21][22]

Also in October 2024, a Florida mother filed a lawsuit against Character.AI and Google, claiming that her 14-year-old son had taken his own life at the encouragement of a Character.AI chatbot which he had built up a relationship with over a period of months.[23][24] Following the death, Character.AI revised its disclaimer reminding users that AI characters are not real people,[23] reduced the likelihood of sensitive or suggestive content from bots used by minors, added a user notification when chat sessions exceed an hour. Character.ai has also deleted custom-made bots flagged as violating their terms. As a result of these changes, some users of the site complained about the bots feeling too restrictive and lacking personality.[25]
