ChatGPT is an artificial intelligence assistant developed by OpenAI, allowing you to communicate in natural language, including Vietnamese. You can ask the tool to explain concepts, draft emails, summarize documents or organize ideas into a plan.
A good way to get started is to choose a small task, provide the necessary information and then check the result. A fluent response is not proof of accuracy.
Understand ChatGPT Before Using It
ChatGPT uses AI models to generate responses based on the request and context provided. ChatGPT is the user-facing product; the AI model is the underlying technology that helps the product process requests.
Unlike search engines, which primarily return lists of websites, ChatGPT usually generates direct answers and lets you ask follow-up questions. However, not every response is checked against information on the Internet. When you need up-to-date information, check whether a search tool is being used and whether the cited sources support the conclusion.
Suitable types of tasks to try include:
Learning: explaining terms, providing examples and creating practice questions.
Writing: drafting emails, creating outlines or improving wording.
Organizing information: summarizing notes, breaking down tasks and suggesting a work schedule.
Technical support: explaining code or suggesting ways to find bugs.
Depending on your account and the available features, you may also see tools for working with files, images or voice. Do not assume that every account has the same capabilities.
Prepare for Your First Use
You need an Internet-connected device, OpenAI’s official ChatGPT website or app, and a specific task. Follow the sign-in instructions shown; check the publisher before installing the app.
Prepare a short passage that contains no sensitive data. For example, use fictional meeting notes rather than uploading an entire customer file. Do not put passwords, verification codes, payment information or internal documents you are not authorized to share into the conversation.
Practice Using ChatGPT in 5 Steps
Open a new conversation and assign a task that is easy to check.
Choose a task you already understand and can evaluate yourself. Summarizing notes or revising an email is usually easier to check than legal advice or financial forecasts. Enter the following request, then paste your notes after removing private information:
Turn the notes below into a to-do list. For each task, state who is responsible and the completion deadline if the notes include that information. If it is missing, write “not yet determined”; do not add it yourself.
Expected result: a list that accurately reflects the original content, without people responsible or deadlines invented by the AI.
Add context and specify the output format.
If you want to draft an email, clearly state the recipient, purpose and facts it may use. Instead of simply entering “write an email”, try this request:
Draft an email in Vietnamese to a colleague asking to reschedule a meeting. Use a polite tone and keep it under 120 words. Reason: a change in work schedule. Suggest two time slots: 9 a.m. on Tuesday or 2 p.m. on Wednesday. Do not add any other reasons.
Expected result: a draft that serves the intended purpose, meets the length limit and adds no extra details. For more complex tasks, see how to write ChatGPT prompts with clear requirements and results that are easy to check.
Read the draft and ask follow-up questions to fix what falls short.
You do not need to rewrite the entire request if the result is close to what you want. Point out passages that are too long, incorrect information or sections that need clarification. For the email in the previous step, you could enter:
Keep the two time slots unchanged, shorten the email to about 80 words and remove the overly formal opening sentence.
When studying, ask for an explanation using a simple example, then answer a check question yourself. When planning, ask it to identify assumptions and missing information.
Expected result: the revised version improves the specific points you raised without losing important facts. If the conversation becomes lengthy, restate the goal and the decisions already made. The article on managing context when AI works on long-term tasks explains this principle further.
Cross-check facts against documents or independent sources.
ChatGPT can generate incorrect information while expressing it confidently. Asking the tool to “check again” is no substitute for independent verification. Choose a checking method suited to the task:
Summaries: compare names, figures, deadlines and main points with the original document.
Information searches: open the cited sources and check their update dates and relevant content.
Calculations: verify the input data, formulas and units.
Code: test it in a separate environment before applying it to a live system.
In the Jump Trading case study published by OpenAI, human review is central to the AI-assisted research process. For beginners, the equivalent principle is to retain the final decision-making authority.
Expected result: you can identify which parts are reliable, which need correcting and which lack sufficient support. Do not use important facts if you have not been able to verify them.
Review the final version before using it in your work.
Treat the response as a draft or suggestion. Read it again before sending an email, publishing content or passing a plan to colleagues. Check both the wording and the factual information, not just spelling.
In the case of The Den using ChatGPT to organize information, OpenAI describes how the team still checks the output and makes the final decisions. This division of responsibilities keeps AI in a supporting role during preparation, while people remain responsible for approval.
If you want to delegate work across apps, distinguish between a conversational assistant and an agent authorized to take action. The article comparing ChatGPT and Muse AI by task helps clarify the selection criteria.
Expected result: the output meets the requirements and is approved by the responsible person before use.
Check Your Trial Run and Troubleshoot Common Issues
Your first trial meets the requirements when the result matches the data, uses the correct format and contains no invented details. For the email example, check whether the two time slots are unchanged, the reason is correct and the length meets the requirement.
If it falls short, address the underlying cause:
Generic response: add the intended audience, goal and specific data.
Missing points: ask it to check each item against the original content.
Invented information: ask it to flag missing facts and separate assumptions from facts.
Misunderstood document: check the uploaded file or paste the relevant section again.
Feature not visible: check the capabilities of your account and the app you are using.
Repeat the process with a few small tasks before expanding your use. Judge the results by whether they are accurate and usable after checking, not just by response speed.
Frequently Asked Questions
Do You Need to Know How to Code to Use ChatGPT?
No. You can enter requests in everyday Vietnamese. More important skills are identifying what needs to be done, providing suitable data and knowing how to evaluate the results.
Should You Buy a Paid Plan When You First Get Started?
Not necessarily. First, try real tasks using your current account’s capabilities. Only consider upgrading once you have identified a limitation that is hindering your work, then check the plan’s features and terms as displayed at the time you sign up.
