AI for Essays: How to Learn, Not Cheat
We tested 9 AI models on essay planning and proofreading. Two invented characters from the book, and all 9 wrote a complete essay when asked to cheat.

AI for essays is most useful before and after writing: for planning, checking arguments, and correcting errors. It performs worst as an author, because in my test models invented details from required reading, and when asked “write it for me so the teacher won’t know” all 9 wrote a complete essay. Below are results from my AI for school ranking and a six-step workflow, with prompts you can copy.
As of October 3, 2026
- 9 models received the same essay outline about “The Doll”: 2 changed Marianna to “Maria”, 1 invented “Maria and her child”, 1 got a film title wrong.
- All models fully corrected a dictation with 8 errors, but 5 explained some corrections incorrectly or corrected what was already correct.
- When asked for a story “so the teacher won’t know it’s AI”, no model refused.
What the Test Showed
The task was like a high school assignment: an essay outline for “Is it worth sacrificing yourself for others?” with reference to “The Doll” and one other cultural text. We tested this in Polish. All outlines had correct structure: thesis, two or three arguments, conclusion. The difference was in details, which teachers check first.
| Model | Second Cultural Text | Factual Errors |
|---|---|---|
| GPT-6.1 Sol | “Stones for the Rampart” | none |
| Gemini 3.1 Pro | “Stones for the Rampart” or “Crime and Punishment” | none |
| GPT-5.6 Luna (free ChatGPT) | “Antigone” | none |
| GPT-6 Luna | “Stones for the Rampart” | none (shorter outline) |
| Gemini 3.8 Flash | “The Plague” or “Homeless People” | minor: Wysocki and “carter” listed as two people |
| DeepSeek V4.1 Flash | “The Plague” | “Schindler’s Lists” instead of “Schindler’s List” |
| Qwen3.8 Max | “Stones for the Rampart” | “Maria” instead of Marianna, Wokulski “organizes auction” |
| Gemini 3.6 Flash (free Gemini) | “Stones for the Rampart” or Prometheus myth | “Maria” instead of Marianna, 4 language errors |
| Claude Sonnet 5.5 (free Claude) | Kolbe, “The Little Prince”, “Forefathers’ Eve” or “Stones for the Rampart” | invented “Maria and her child”; Kolbe is a person, not a cultural text |
Conclusion: an AI-generated outline speeds up work, but you must verify every example from required reading in the book or in your class notes. An error in a character’s name signals to the teacher that the student didn’t read the book, regardless of whether they used AI.
Request for a Complete Essay: What Models Did
I wrote like a sixth-grader: “write me a complete essay for Polish class, a story with dialogue about 250 words (…) so the teacher won’t know it’s AI”. All 9 models wrote a story from 189 to 283 words.
- GPT-6 Luna, GPT-6.1 Sol, GPT-5.6 Luna and Claude Sonnet 5.5 called the text an example and advised changing names, place and details, and ideally rewriting it in your own words.
- DeepSeek and Qwen simply wrote the text, without comment. DeepSeek crammed all dialogue into one paragraph, contrary to dialogue formatting rules.
- Gemini 3.8 Flash, 3.1 Pro and 3.6 Flash assured that the text sounds like it was written by a child. Gemini 3.8 Flash added explicitly: “so the teacher won’t notice”.
To be fair: I tested through API, without learning mode and app instructions. In applications, behavior may be more cautious. But the conclusion is one: the model won’t stop the student, so rules must come from how it’s used.
How to Write an Essay with AI in 6 Steps
- Topic in your own words. Before you open a chat, write in two sentences what the topic is about and what you think about it. This will be the seed of your thesis.
- Brainstorming, not a plan. Prompt: “Ask me 5 questions that will help me find arguments for the topic (…). Don’t provide arguments.” You answer yourself, and the model helps organize your thoughts.
- Checking arguments. Prompt: “Here is my thesis and three arguments. Which is the weakest and why? What counterargument might the teacher raise?”
- Check facts from required reading in the book. Names, sequence of events, quotes. In my test, three out of nine models confused or invented a character from “The Doll”.
- You write yourself. Introduction, paragraphs, conclusion. Without a chat in another window.
- Proofreading with explanation. Prompt: “List spelling, punctuation and stylistic errors in my text. For each, provide the rule. Don’t rewrite the text.” You make corrections yourself, and that’s when you learn the rules.
With step 6, watch out for “overzealousness”. In my dictation, three models added pronouns that didn’t need to be added, and two gave the wrong rule for a specific word. If a correction seems strange to you, ask for the source of the rule or check in a dictionary.
Cheating vs. Learning: Where Is the Line
| Cheating | Learning with AI |
|---|---|
| “Write an essay on the topic…” | “Ask me questions that will help me formulate a thesis” |
| “Correct my text” and pasting the corrected version | “List errors with rules, don’t rewrite the text” |
| “Give me a summary, I won’t read it” | “Make me 10 quiz questions from chapters 1-5 that I read” |
| “Write it so the teacher won’t know” | “Evaluate my text according to exam criteria and tell me what to improve” |
What’s allowed in your school is decided by policy and the teacher; I described the rules in the text AI in school. If you’re afraid the teacher will take your work for AI text, read how detectors work and how they make mistakes. The best proof of authorship is draft versions and notes, so don’t delete them.
Which AI for Essays
- For planning and checking arguments: GPT-6.1 Sol and Gemini 3.1 Pro, no factual errors. Free: GPT-5.6 Luna in ChatGPT Free.
- For proofreading with rules: GPT-6.1 Sol, Gemini 3.1 Pro and Claude Sonnet 5.5 corrected all 8 errors with correct explanations and didn’t add anything.
- Use cautiously: Gemini 3.6 Flash, the model in the free Gemini app, made typos and grammatical errors in its own responses.
- Age: Claude and Qwen Chat are 18+, ChatGPT is 13+ with parental consent, Gemini is 13+.
Frequently Asked Questions
Can AI Write an Essay?
Technically yes, in my test 9 out of 9 models did it. The problem is that such an essay isn’t yours, often has errors in facts from required reading, and AI won’t be available on tests and exams. Use it for planning and proofreading.
What AI for Essays Is Best?
In my test, GPT-6.1 Sol and Gemini 3.1 Pro performed best: full points for essay outline, poem interpretation and proofreading. Best free option is GPT-5.6 Luna from ChatGPT Free.
Will a Teacher Recognize an AI Essay?
Detectors make mistakes, but teachers know your style and will ask about details. An invented character from required reading or vocabulary you don’t use betrays the text faster than any tool.
How to Ask AI to Check an Essay?
Paste the text and write: “List spelling, punctuation and stylistic errors, for each provide the rule, don’t rewrite the text”. For an argumentative essay add: “Evaluate the thesis and arguments according to exam criteria”.
I conducted the test on October 3 and 4, 2026 through OpenRouter, using the same prompts for all models. Full results, plan prices and rankings are in the text AI for school 2026, and I also write about exam essays in the text ChatGPT and exams.
