To use ChatGPT, sign up at chatgpt.com or the app, type a clear question or instruction, and refine the answer with follow-ups. The clearer and more specific your prompt, the better the result.

Getting started

Create a free account on the web or mobile app. Type your request in plain language — a question, a writing task, or a problem to solve. ChatGPT replies instantly, and you can keep the conversation going with follow-ups like ‘make it shorter’ or ‘explain that differently’.

Getting better answers

Be specific and give context: state the role, audience, format and length you want (‘Write a friendly 100-word reply to this customer email’). Paste in relevant text for it to work from. Iterate — treat the first answer as a draft and refine it. Use voice mode or image upload where helpful.

Things to watch

ChatGPT can be wrong. AI can fabricate facts, figures and citations with total confidence (a “hallucination”). Treat AI output as a draft and verify anything important against a reliable source — this matters most for medical, legal, financial and academic use. Verify facts, figures and especially citations. Avoid pasting sensitive personal or company data, and remember free/Go tiers in the US show ads. For higher limits and the latest models, Go ($8/mo) or Plus ($20/mo) help.

If you find yourself juggling a separate subscription for chat, automation, transcription and image generation, one option worth knowing is a single platform that runs them together — osFoundry is one such agentic AI platform that consolidates chat, agents and internal apps in one workspace, with a bring-your-own-key model so you choose the underlying AI.
