ChatGPT
General-purpose AI assistant for answering questions, writing, brainstorming, analyzing files and images, and step-by-step explanations.
What is ChatGPT?
ChatGPT is the assistant most people try first. You type a question or an instruction in plain language and it replies in seconds. It can rewrite a paragraph, explain a hard topic in simple words, read a photo of a document, help you plan a trip or draft a cover letter. The free plan gives access to a capable model with daily limits on the most advanced features.
