ChatGPT

ChatGPT is the most widely used AI assistant in the world, built by OpenAI. It answers questions, drafts and edits text, explains complex topics, writes and debugs code, and can browse the web, analyze files, and generate images through its integrated tools.

The free tier covers everyday tasks, while paid plans unlock the latest models, higher limits, advanced data analysis, and custom GPTs. Available on the web, desktop, and mobile, it has become the default starting point for anyone exploring what AI can do.
