OpenAI's general-purpose assistant for writing, research, images, voice and code.
ChatGPT is a conversational AI assistant from OpenAI. It handles drafting, summarizing, brainstorming, data questions and code, and it can analyze uploaded files and search the web when that feature is enabled. Image creation and voice conversation are available inside the same chat window, and custom GPTs let people package instructions for repeated tasks. It suits individuals and small teams who want one tool for many everyday tasks. Answers can sound confident while being wrong, so facts, numbers and citations still need checking. Free access has usage limits, and the feature set changes often, so the current plan list on the website is the reliable reference.
Free tier available; paid plans unlock higher limits. Check the pricing page for current prices.
