ChatGPT launched in November 2022 and became the fastest-growing consumer application in history at the time, introducing a mass audience to conversational AI in a way no prior product had, and remains the largest chatbot by user base years later. OpenAI built it on its GPT model family, with new versions rolling out regularly since.
Its feature set has broadened well past text chat: image generation, voice conversation, web browsing, file and image analysis, and custom GPTs that let users configure specialized versions for repeated tasks all live inside the same product now. A large third-party ecosystem, plugins, integrations, and an extensive base of tutorials and guides, has grown up around it specifically because of its scale.
A free tier covers standard access with usage limits, and ChatGPT Plus starts around $20 a month for higher limits, faster responses, and early access to new features, with higher enterprise and Pro tiers above that. For anyone who wants the most widely adopted, most extensively documented AI chatbot with the broadest third-party ecosystem built around it, ChatGPT's scale remains its clearest advantage over smaller competitors.
