Learn ChatGPT

Get useful, checkable answers from ChatGPT instead of confident guesses.

Free to start. Built from a single prompt. No credit card.

ChatGPT is OpenAI's chat assistant built on large language models, and using it well is a skill: the same tool that drafts a clear email in seconds can also invent a citation with total confidence. Getting good results means giving context and constraints, iterating with follow-up messages, using features like custom instructions, file uploads and web search where your plan offers them, and checking anything factual. It also means knowing what not to paste in. This course is independent and not affiliated with OpenAI. Learnr builds a ChatGPT course around the tasks you want help with, in short lessons with prompts to try yourself.

How to learn ChatGPT, step by step

Learn what is behind the chat box. ChatGPT predicts likely text based on its training and what is in the conversation. That explains why it writes fluently, why it can be confidently wrong, and why the wording and context you give change the answer so much.
Write prompts with four parts. State the goal, give relevant context, name the format, such as a table or 150 words, and add constraints like audience or tone. Paste an example of what good looks like when you have one.
Iterate instead of starting over. Treat the first answer as a draft and reply with specific changes: shorter, more formal, add counterarguments, use my numbers. Ask it to list assumptions or questions it has before answering complex requests.
Set up custom instructions. Use custom instructions to tell ChatGPT about your role and preferred style once, rather than in every chat. Review what memory has stored if that feature is on, and delete anything you do not want kept.
Work with files and verify everything. Upload a document or spreadsheet and ask for summaries, comparisons or charts, then spot-check figures against the source. When it cites the web, open the links. Learnr practice in short daily doses builds these checking habits.
Protect privacy and know the limits. Do not paste passwords, client data or sensitive personal information unless your organization has approved it. Check your data and training settings, and avoid relying on ChatGPT for medical, legal or financial decisions without a professional.

How long does it take to learn ChatGPT?

The basics take an hour or two. Getting consistently good results across writing, research, analysis and planning usually takes 2 to 4 weeks of daily use, depending on how varied your tasks are and how deliberately you practice.

What you need before you start

Nothing beyond basic computer skills and a ChatGPT account. Knowing your own subject well helps most, because it lets you judge whether answers are actually right.

Common mistakes to avoid

Trusting citations, statistics and quotes without checking them. ChatGPT can produce sources that look real but do not exist, so open every reference.
Writing one vague line and accepting the result. Add context, audience, format and an example, then refine with follow-ups.
Pasting confidential work or personal data into chats without checking your employer policy and the account data settings.

ChatGPT questions, answered

Is this course made by OpenAI?

No. Learnr is independent and not affiliated with OpenAI. The course teaches practical skills for using ChatGPT, and the same habits carry over to other chat assistants.

Is the free version of ChatGPT enough to learn?

Yes, for learning prompting and good habits. Paid plans offer more usage and access to more capable models and features, and what each plan includes changes over time, so check the current plan details.

What is the difference between ChatGPT and prompt engineering?

ChatGPT is one specific product. Prompt engineering is the general skill of writing instructions for language models, which applies to ChatGPT and to other assistants and APIs.
