ChatGPT

ChatGPT is OpenAI's AI assistant, used in a browser at chatgpt.com and in matching desktop and mobile apps. You type a request in plain language and refine from there — it is the tool that put conversational AI in front of a general audience, and it remains one of the most capable and widely supported.

It handles the full range of language and reasoning work: drafting and rewriting, brainstorming, explaining unfamiliar subjects, writing and debugging code, summarising long text, and turning rough input into structured output. With the right tools enabled it also works with images and can search the web, and it can take files as part of a conversation.

It fits a broad audience — students, writers, developers, and casual users alike — and is a sensible first assistant to try precisely because so much documentation and community help exists for it.

Getting started is quick: create a free account at chatgpt.com with an email address; the free tier needs no payment. Paste in something real you have to write or read and ask for a specific outcome.

The honest limits. The free tier runs a default model with message and usage caps and fewer features; paid consumer plans (Go, Plus, Pro) raise limits and add stronger models and tools. ChatGPT can state wrong things fluently, so verify anything that matters. Model names, defaults, and limits change frequently, and the OpenAI developer API is a separate product billed apart from any ChatGPT subscription.
