New AI seems to appear every month. I decided to dig into the history of hem in order to crate a brief chronology that focuses on publicly accessible chatbots (not internal research models or early limited-access releases. Many other AI assistants (e.g., Ernie Bot in China, Perplexity AI, Amazon Alexa+ web chatbot) have also become available in various regions and forms, especially by 2024–2026, but specific launch dates vary by market and rollout strategy.
Some chatbots have evolved over time (e.g., Bard became Google Gemini), so “release” reflects the first broad availability to general users.
Here’s a brief chronology of major AI chatbots that became available to the public, listed in order of their public release or general availability (primarily focused on the modern generative AI era):
Replika – Launched in November 2017, one of the earliest modern AI chatbots designed as a conversational companion.
ChatGPT – Released by OpenAI on November 30, 2022, and widely recognized as the breakthrough generative AI chatbot that sparked mainstream interest in conversational AI.
Character.ai – First beta made public on September 16, 2022, letting users chat with or create character-based bots; significant growth followed into 2023.
Anthropic’s Claude (public) – First broadly available version of the Claude AI chatbot launched in July 2023, after initial private releases earlier that year.
Google Bard – Announced and publicly launched in March 2023 as Google’s first consumer AI chatbot; later rebranded under the Gemini name.
Microsoft Copilot - Public Release: March 7, 2023 - Microsoft Copilot was launched as a generative AI chatbot and assistant, integrated across things like Microsoft 365 (Word, Excel, Outlook), Windows, and Bing/Edge. In the broader AI chatbot timeline, Copilot was one of the first major assistants launched by a major tech company after ChatGPT’s debut in late 2022.
