ChatGPT
ChatGPT is OpenAI’s AI chatbot. You type or speak a request and it answers, writes, explains, analyses files or creates images.
In more detail
ChatGPT launched in November 2022 and quickly became one of the fastest-growing consumer apps ever, bringing generative AI into the mainstream. It runs on OpenAI’s GPT models.
It has free and paid plans. Features include web search, file and image uploads, voice conversations, memory and custom GPTs. Like any chatbot, it can hallucinate, so verify important answers.
Example
Asking ChatGPT to turn your meeting notes into a short summary with action points.
