ChatGPT

What is ChatGPT?

ChatGPT is an AI assistant that helps you get answers, find inspiration, and be more productive. It responds to prompts typed into a chat composer and is described on the page as able to produce "smarter responses," and to support uploading files, images, and more after logging in.

ChatGPT is browser-based and offered through a web interface with a mobile layout. The page states that "ChatGPT is AI and can make mistakes," and that by using it you agree to the Terms and Privacy Policy, with chats possibly reviewed and used to improve AI models.

How to use ChatGPT?

Type a question or prompt into the chat composer. The landing composer invites you to "Chat with ChatGPT," with the heading "What are you working on?" and the placeholder to "Ask ChatGPT."

Logging in is presented as optional for basic chat but necessary for several features and conveniences. Without logging in, you can still enter a prompt. If you log in, you get answers based on saved chats, you can create images, and you can upload files and photos. The page repeatedly notes that adding files, adding more photos, using web search, creating images, and running deep research require logging in.

When using the composer, you can enter text and, depending on your login state, attach images or files. The page lists supported image formats for upload: .avif, .bmp, .gif, .heic, .heif, .jpeg, .jpg, .png, and .webp. You can clear the current chat from the menu, which the page warns will discard the current conversation unless you sign up or log in to save chats.

Core features of ChatGPT

AI chat responses

Answer prompts typed in the chat composer. The home screen phrases it as getting "smarter responses" and being able to "upload files, images, and more" when logged in.

File and image uploads

Attach files and photos to a chat. The page states that adding more photos, adding files, and uploading images are limited without logging in, and that logged-in users "can upload files, images, and more."

Web search

Use a web-search option in the composer. Web search is shown as requiring login ("Web search — Log in to use...").

Image creation

Create images from within ChatGPT. The page labels this "Create image" and indicates it requires login ("Create image. Log in" / "Log in to use").

Deep research

Run multi-step research that compares sources and produces cited reports you can save to revisit later. The page describes this as "Turn questions into research" and states you must log in to run it.

Conversation history and saved chats

After logging in, answers are based on saved chats, conversations can be saved, past answers can be searched, and you can pick up where you left off. The page presents chat search and conversation history as login-gated conveniences.

Add anything / file drag

A file drag area labeled "Add anything" lets you bring in content. The page lists supported image formats for upload, and notes that adding more photos may be limited unless logged in.
