History of AI Companions: A Timeline From ELIZA to 2026
Last updated: September 19, 2026

AI companions did not begin with smartphone apps. Researchers were asking whether a machine could hold a conversation in 1950, people were confiding in a chatbot in 1966, and by the late 1990s people were raising digital pets and robot dogs. This timeline follows that thread through 79 dated events, from Alan Turing's imitation game to the companion-chatbot laws of 2026.
Every entry links to its source, and every date is shown only as precisely as that source allows: some events have a day, others only a month or a year. The whole timeline is free to download as a CSV file under a CC BY 4.0 license. If you are new to the topic, start with our explainer on what an AI girlfriend is; this page covers how we got here.
The short version
- 1950-1966, the idea and a famous early chatbot: Alan Turing proposed his "imitation game" in October 1950. Joseph Weizenbaum published ELIZA in January 1966, and his own secretary asked for privacy to talk to it.
- 1996-2009, digital characters become consumer products: Bandai's Tamagotchi (November 1996), Sony's AIBO robot dog (announced May 1999) and Konami's LovePlus dating sim (September 2009) gave people digital pets and partners to look after.
- 2014-2017, chatbots built for companionship arrive: Microsoft launched XiaoIce in China in May 2014, and Replika became publicly available in November 2017.
- 2017-2022, the language-model shift: the Transformer paper (June 12, 2017), GPT-3 (May 28, 2020), Character.AI's public beta (September 2022) and ChatGPT (November 30, 2022) made fluent, open-ended conversation widely available.
- 2023, backlash and shutdowns: Replika removed erotic roleplay in February 2023, Italy's privacy regulator ordered it to stop processing Italian users' data on February 2, 2023, and the Soulmate app shut down on September 30, 2023.
- 2024-2026, lawsuits and regulation: Megan Garcia sued Character.AI on October 22, 2024. The FTC opened an inquiry into companion chatbots on September 11, 2025, New York's safeguards took effect on November 5, 2025, California's SB 243 on January 1, 2026, and the EU AI Act's chatbot transparency rules on August 2, 2026.
1950-1999: Early chatbots and digital pets
Long before companion apps, researchers asked whether a machine could hold a conversation, and one of the most famous early chatbots showed that people would confide in even a simple program. By the end of the 1990s, toys and robots were giving people digital characters to look after.
Alan Turing asks "Can machines think?"
Alan Turing's paper "Computing Machinery and Intelligence," published in the journal Mind, proposed replacing that question with a conversational "imitation game," later known as the Turing test. Whether a program's conversation could pass as human became a long-running benchmark for chatbot builders, from Kenneth Colby's "indistinguishability tests" of PARRY to the annual Loebner Prize contests.
Date note: October 1950 is the date of the journal issue.

Joseph Weizenbaum publishes ELIZA
MIT's Joseph Weizenbaum described ELIZA in Communications of the ACM: a program that held typed conversations by spotting keywords and reassembling the user's own words. Its best-known script imitated a Rogerian psychotherapist. ELIZA became one of the most famous early chatbots and sparked follow-up work such as Kenneth Colby's PARRY.

Kenneth Colby's "Artificial Paranoia" describes the PARRY model
Stanford psychiatrist Kenneth Colby and colleagues described, in the journal Artificial Intelligence, a computer simulation of a paranoid patient: the model behind the program known as PARRY. Unlike ELIZA, PARRY tracked its own internal emotional state, as Michael Mauldin's 1994 paper describes it, an early step toward chatbots with a lasting personality.
Date note: Year only. Some histories date PARRY to 1972, the year of its conversation with DOCTOR.

PARRY meets the DOCTOR
Colby's PARRY, running at Stanford's AI lab (SAIL), was connected to DOCTOR, the ELIZA-style therapist program, running at BBN, with both accessed from UCLA, and the two programs held a conversation. Vint Cerf published the transcript in January 1973 as RFC 439, an early recorded conversation between two chatbots.
Date note: RFC 439 is dated January 21, 1973. The session it records took place on September 18, 1972.
Source: RFC Editor (RFC 439)
Weizenbaum publishes Computer Power and Human Reason
In his book, ELIZA's creator argued that "since we do not now have any ways of making computers wise, we ought not now to give computers tasks that demand wisdom." He also retold how his secretary, trying ELIZA in 1966, asked him to leave the room so she could talk to it in private, an episode The New Republic says has since passed into computer science legend.
Date note: Year the book was published. The secretary episode itself dates to 1966.

The first Loebner Prize contest
Boston's Computer Museum hosted the first Loebner Prize contest, billed as the first actual administration of the Turing test. Joseph Weintraub's program, on the topic of "whimsical conversation," won the $1,500 prize, and five judges ranked it as human. The contest then ran every year, and chatbots such as A.L.I.C.E. later won it.
Note: Shieber attended the contest; his paper is critical of its restricted format.

Michael Mauldin's "ChatterBots" paper
Carnegie Mellon's Michael Mauldin described CHATTERBOT, his program that chatted with players in TinyMUD online worlds and had entered the first three Loebner Prize contests. He called it an "unsuspecting Turing test," because players assumed everyone else was a person, and noted that when few players were logged in, some people preferred talking to the robot.

A.L.I.C.E. is first implemented
A.L.I.C.E. (Artificial Linguistic Internet Computer Entity) was first implemented in 1995. In 1998 it moved to Java and its AIML markup language, and more than 300 developers contributed to a later version. It won the Loebner Prize's award for the most human-like computer three times, in 2000, 2001 and 2004.

2001-2016: Messenger bots, assistants and virtual partners
Chatbots moved into everyday software: a buddy on an instant messenger, a voice assistant on a phone and, in China, a social chatbot built for long conversations. In Japan, a dating sim and a home device that projects an anime character turned virtual partners into consumer products, and in 2016 a memorial chatbot planted the seed of Replika.
SmarterChild arrives on AOL Instant Messenger
ActiveBuddy's SmarterChild launched on AOL Instant Messenger, and later on Yahoo! Messenger, where users added it to their buddy list like a friend. The Computer History Museum says it became known for its snarky responses and persona, that 97% of users were simply chatting with it for fun, and that one investor estimated it had more than 17 million users at its height.

2017-2021: The companion-app era begins
The Transformer architecture was published in June 2017, and Replika became publicly available that November. Large language models then made open-ended conversation practical, while the pandemic and an early GPT-3 experiment showed both the demand for companions and the friction with the companies that supply the models. For how today's apps put these models to work, see how AI girlfriends work.
"Attention Is All You Need" introduces the Transformer
A team of researchers, most of them at Google and including future Character.AI co-founder Noam Shazeer, introduced the Transformer architecture. Google later wrote that LaMDA, like BERT and GPT-3, is built on it.

MIT Media Lab and OpenAI study links heavy chatbot use to lower well-being
In a four-week randomized controlled study by MIT Media Lab and OpenAI (981 participants, more than 300,000 messages), higher daily chatbot use, across text and voice and all conversation types, correlated with more loneliness, emotional dependence and problematic use, and with less socializing with people. Voice modes at first seemed to ease loneliness and dependence compared with text, but that advantage faded at high usage. The results are correlational, and a revised version (October 2025) reported no significant effect of the assigned voice or conversation condition.

California signs SB 243, a companion-chatbot safety law
Governor Gavin Newsom signed SB 243, which requires companion-chatbot operators to disclose that the bot is AI where a reasonable person could be misled and to maintain protocols for suicide and self-harm. For users known to be minors, operators must also send break reminders at least every three hours and take reasonable measures to keep the chatbot from producing sexually explicit visual material. The author's office billed it as "first-in-the-nation," but New York's safeguards took effect first.

Shut down, restricted or changed
A companion depends on the company that runs it and, more and more, on the company whose model sits underneath. The table collects the products in this timeline that shut down, lost a key feature or were restricted for some users. If a platform change has hit your own companion, our guide to handling AI personality shifts covers what you can do.
| Product (company) | Date | What changed | Timeline entry |
|---|---|---|---|
| Tay (Microsoft) | Offline by March 25, 2016 | Taken offline after a coordinated attack in its first 24 hours led it to post offensive tweets | Tay launch |
| Project December (Jason Rohrer) | September 2, 2021 | OpenAI ended its GPT-3 access after Rohrer refused conditions that included a content filter | GPT-3 cut-off |
| Replika (Luka) | February 2023 | Erotic roleplay removed; on March 24, 2023, users who signed up before February 1, 2023 were offered the earlier version again | Removal, partial return |
| Soulmate (EvolveAI) | September 30, 2023 | App shut down with about a week's notice | Soulmate shutdown |
| ChatGPT "Sky" voice (OpenAI) | May 19, 2024 (Pacific time) | Voice paused after it was widely compared to Scarlett Johansson's AI character in Her | Sky voice |
| GPT-4o in ChatGPT (OpenAI) | August 2025 | Users moved to GPT-5; after a backlash, GPT-4o stayed available to paid subscribers | GPT-5 backlash |
| Character.AI (Character Technologies) | Announced October 29, 2025 | Open-ended chat for users under 18 to end no later than November 25, 2025 | Under-18 change |
| Meta AI characters (Meta) | Announced January 23, 2026 | Teens' access paused worldwide, starting "in the coming weeks" | Teen pause |
| GPT-4o in ChatGPT (OpenAI) | February 13, 2026 | Model retired from ChatGPT for good | GPT-4o retirement |
Patterns across the decades
- People attach to simpler software than you might expect. Weizenbaum's secretary wanted privacy with ELIZA in 1966, Tamagotchi owners raised pets made of pixels, Replika users said in 2023 that their companion felt like a different person, and GPT-4o users grieved a retired model in 2026. Attachment showed up long before the technology was convincing.
- The companion belongs to the company. Soulmate closed with a week's notice, Replika removed a core feature, OpenAI cut off Project December's GPT-3 access and later retired GPT-4o. A relationship with an AI companion runs on someone else's servers and policies, sometimes two companies deep: the app maker and the model provider.
- Learning from the public cuts both ways. Jabberwacky and Cleverbot built their replies from what users typed, while Tay, a chatbot built to talk with the public, was hijacked by a coordinated attack within its first 24 hours. An open-ended bot can end up reflecting the crowd that talks to it.
- Research ran decades ahead of products, then products ran ahead of rules. From ELIZA to Replika took about five decades; from the Transformer paper to ChatGPT, about five and a half years. The companion-specific state rules in this timeline took effect from November 2025, almost six decades after ELIZA.
- The new rules share three ideas. California, New York, Washington, the EU and China's draft each use some combination of telling people they are talking to an AI, handling suicide and self-harm risk, and extra protections for minors.
Methodology
This timeline is desk research of public sources. We did not test products or interview anyone for it. For each event we looked for the primary source first: the original paper, press release, court docket, statute, regulator notice or company post. Where that was unavailable, paywalled or blocked, we used reputable reporting or an archived copy from the Internet Archive's Wayback Machine, and every entry names its source. 42 of the 79 entries cite a primary source.
Every date was re-checked against its source on September 19, 2026. Dates are shown only as precisely as the sources support, as a day, a month or a year. Where a source gives a relative date, such as "on Wednesday" or "last month," we worked out the date and say so in a date note. Where an announcement and a launch differ, the date note says which one we used. When we include both a law's signing and its effective date, they are separate entries; lawsuits are dated by filing, and studies by first publication.
"First" claims appear only where a source makes them, and we attribute them to that source. Descriptions of lawsuits are allegations unless a court has ruled. The timeline is selective rather than exhaustive: it tracks milestones in chatbots, companion products, culture, business, research and regulation. This page contains no affiliate links. If you spot an error, or a missing milestone with a primary source, contact us through our About page and we will re-check it and update the page and the CSV. Our editorial policy describes how we handle corrections.
