ChatGPT is OpenAI's conversational AI assistant. Use it to explain a topic, draft or revise text, analyze material you provide, or develop a first version of a document. A useful starting task is small and concrete: give it rough notes and ask for a short email, a structured outline, or an explanation suited to your audience. This guide explains its purpose and a starting workflow. [1]
Main features
ChatGPT can work with natural-language instructions and supplied context such as files, projects, web search, and plugins. The current documentation distinguishes Chat for conversation, Work for larger tasks that produce a reviewable result, and Codex for software-development workflows. Features and usage allowances depend on your account and plan; a chat subscription should not be confused with API billing. [1]
Who should consider it?
A conversational assistant for writing, research, file analysis, and everyday tasks. Choose it for the task described here, then compare the requirements of your own project with its documented capabilities.
Getting started
- Open chatgpt.com and sign in.
- Choose Chat for a first question or drafting task. Provide the relevant notes or file.
- Describe the audience, desired format, and outcome. Example: 'Turn these notes into a 150-word customer update. Flag missing information.'
- Read the draft, correct facts, and ask for a specific revision. For a larger task, consider Work.

Free access and pricing
A Free plan is available. Paid individual plans include Go, Plus, and Pro; the documentation lists Plus at US$20 per month. Business, education, and enterprise options also exist. Limits and regional billing can differ; use the official plan page for the current offer. API usage is billed separately. [3]
Limitations and practical advice
eWiki's practical advice: check names, numbers, quotations, and references against your original material. Tell ChatGPT when the task must use only supplied sources. A fluent answer can still omit a constraint or make an unsupported claim. Do not judge a tool's suitability from one generated response.
