How to use ChatGPT to write essays

The most common mistake when using ChatGPT for essays is starting with a vague prompt like “write me an essay about climate change”. The result will be generic and without a clear argument. Before writing, define these three points:

1. The specific topic: not “climate change” but “the economic impact of net-zero carbon policies on developing countries”
2. Your stance or central argument: what you want to demonstrate or argue (e.g. “these policies need adjustment to avoid increasing global inequality”)
3. The audience: who are you writing for? An academic essay, an opinion essay for a blog, or an exam response have different tones

Once you have these three points clear, the first message to ChatGPT can be something like:

“I need to write an 800-word argumentative essay about the economic impact of net-zero carbon policies on developing countries. My argument is that these policies, without transition funds, increase inequality. The audience is academic. First help me create a 5-part structure for the essay.”

ChatGPT will give you a structure you can adjust before starting to write each section.

With the structure defined in the previous step, ask ChatGPT to write the introduction. The key is to give it specific context so the result is useful:

Example prompt:

“Write the introduction of this essay. It should have 3 paragraphs: the first presents the topic and its current relevance, the second states the specific problem (that net-zero carbon policies without transition funds increase inequality), and the third announces the central argument and the essay’s structure. Academic tone, without unnecessary jargon.”

When ChatGPT gives you the draft:

1. Read the first paragraph out loud. If it sounds artificial or too formal for your voice, rewrite the longer sentences in your own words
2. Verify that the central argument is clear at the end of the introduction
3. Note what examples or data you will add that ChatGPT cannot know (your experience, data from your country, local examples)

The introduction is the section most worth rewriting in your own voice, because it is the first thing your audience reads.

For the body of the essay, work section by section. Each time you request a new section, include in the prompt:

• The title or topic of that section
• The argument it should develop
• The points or examples it should include
• The approximate length (e.g. “2 paragraphs of about 150 words each”)

Example prompt for a development section:

“Write the second section of the essay (titled ‘The Cost of the Energy Transition in Emerging Economies’). It should argue that developing countries have a historically lower carbon footprint but carry a disproportionate transition cost. Include the example of fossil fuel subsidies as an economic relief mechanism that these policies eliminate. 2 paragraphs, about 150 words each, academic tone.”

How to personalize each section once you have it:

• Add data or statistics you have researched (real sources that you verify)
• Replace the generic examples ChatGPT uses with specific examples from your context
• Adjust the tone if there are phrases that sound too formal or too simple for your audience

The conclusion:

Ask ChatGPT to write the conclusion with a prompt similar to the previous sections, but with these additional instructions:

“Write the conclusion of the essay. It should: return to the central argument (without repeating it word for word), synthesize the main development points, and end with a reflection on the future implications of this topic. Without repeating the exact words of the introduction. 1 to 2 paragraphs.”

Use ChatGPT to review the full essay:

Once you have all the sections, paste the complete text into a new message and ask:

“Review this essay and tell me: is the central argument clear from the introduction to the conclusion? Are there sections that do not connect well with the argument? Are there unnecessary repetitions? Give me only the problems found, without rewriting the text.”

This gives you an objective review before editing. Then you decide what to fix.

To learn how to use ChatGPT for other types of written text, the tutorial How to write professional emails with ChatGPT shows techniques that also apply to editing and tone.

This is the step that most distinguishes a generic AI essay from one that is actually worth reading. Before submitting or publishing your essay, do this review:

Signs that the text sounds too much like AI:

• Long, symmetrical sentences with the same structure one after another
• Generic transition phrases like “In conclusion”, “It is important to highlight”, “It is worth mentioning”
• Complete absence of personal or local examples
• Uniformly formal tone with no variation

How to edit to sound like you:

1. Read the essay out loud. Where you stumble or it sounds strange, rewrite that phrase
2. Vary sentence length: alternate short sentences with longer ones
3. Add at least one specific example or piece of data from yourself in each main section
4. Replace generic transition phrases with more natural connectors (“This means that…”, “The key lies in…”, “What changes here is…”)
5. Check that the central argument is yours: do you actually agree with what the essay says? If not, adjust it

About citations and references: ChatGPT can invent sources that do not exist. If the essay includes citations, verify each one in Google Scholar or the original source before including it. Use ChatGPT only to format citations you have already verified.

If you need a quick essay of 400 to 600 words, you can do it in a single conversation with this initial prompt:

“I need an essay of [400-600] words about [topic]. My argument is [your stance]. The audience is [academic / general / for a blog]. Structure: introduction (1 paragraph), three development points (1 paragraph each) and conclusion (1 paragraph). Tone [academic / conversational / journalistic]. Start writing directly.”

ChatGPT gives you the complete essay at once. Then:

1. Read the full text
2. Identify the 2 or 3 sentences that sound most like AI and rewrite them
3. Add a personal or specific example somewhere in the development
4. Verify that the conclusion connects with the introduction

With these four adjustments, the essay goes from generic to yours in under 15 additional minutes.

Problem	What to do
ChatGPT stops in the middle of the essay	Write “Continue from where you left off” or “Continue with the next section” in the same chat
The essay does not develop the argument I asked for	Start a new chat and add more context: your exact thesis, the points it should cover and the audience
The text sounds too generic or lacks personality	Review step 5 of this tutorial: editing is mandatory for the essay to sound like you
I ran out of free plan messages	The limit renews after 5 hours; if you need more, consider ChatGPT Plus ($20/mo)
ChatGPT includes citations I cannot verify	Do not use those citations; ask ChatGPT to reframe the argument without specific sources, and add your own verified sources
The essay has more words than I need	Paste the text and ask: “Summarize this essay to [N] words while keeping the main arguments”
