You finish a research paper, hit save, and then realize you used ChatGPT for two paragraphs of brainstorming and one rewrite. Now you have to figure out how to cite AI in papers without getting flagged for plagiarism or missing your professor's policy by accident. The rules changed again in late 2025, so the answers your roommate gave you last semester are probably wrong.
This guide walks through how to cite AI in papers using the current MLA 9 and APA 7 rules, with copy-ready examples for ChatGPT, Claude, Gemini, and Perplexity. It also covers what to do when your tool does not have a shareable link, when you only used AI for editing, and how to write the methods note that most professors actually want to see. The goal is simple. Give credit cleanly, document what you did, and stay on the right side of your school's policy without rewriting your whole paper.

Why citing AI matters more in 2026
Two years ago, citing AI was optional in a lot of classes because nobody had clear rules. That window is closed. Most universities updated their academic integrity policies during the 2024 to 2025 school year, and both MLA and APA published revised guidance that students are now expected to follow. If you used AI to draft, summarize, translate, brainstorm, or even just polish a sentence, your paper should reflect that somewhere, either in a citation, a methods note, or an acknowledgment line.
The reason is straightforward. Schools are not trying to catch you for using AI. They are trying to make sure your paper accurately represents what you did and what the tool did. A clear citation protects you twice. It shows you understood the assignment well enough to disclose, and it gives the grader a record of what came from where, which is often the difference between a warning and an honor code referral if something gets questioned later.
The other reason is that AI detectors are still messy. Posts about why detectors get false positives explain how innocent writing can get flagged. A clean citation history is one of the strongest defenses if you are ever asked to prove your process.
Step zero: read your professor's policy first
Before you even open MLA or APA, find your professor's actual rule. This sounds boring, but it is the single most important step. The official style guides only tell you the format. Your professor tells you whether AI is allowed at all, what kinds of use need disclosure, and whether they want it cited in the bibliography or just acknowledged in a footnote.
You will usually find the rule in three places. First, check the syllabus under "Academic Integrity" or "Use of Generative AI." Second, look at the assignment instructions for that specific paper because some assignments allow AI for brainstorming but ban it for drafting. Third, check the course Canvas, Brightspace, or class site for any updated AI policy posted after the semester started.
If you cannot find a rule, send a short email. Something like: "Hi Professor X, I want to use ChatGPT to help me brainstorm a thesis for the midterm paper. Is that okay if I cite the conversation? Thanks." Save the reply. If anything comes up later, that email is your proof.
A quick decision tree
If your professor allows AI with citation, follow the MLA or APA format below. If they allow it without citation, still keep a methods note for your own records. If they ban AI, do not use it at all on that assignment, including for editing or grammar. The risk is not worth a few cleaner sentences.
How to cite AI in MLA 9 format
MLA does not list AI as the author because, in MLA's view, an AI tool cannot be a creator in the same way a person can. Instead, you describe what was generated, name the tool, list the company, give the date, and provide a URL. The 2025 update added two important changes: include the model name or version in the Version slot, and use a stable shareable link to the conversation if your tool offers one.
MLA template
Description of generated content. Tool Name, version, Company, Date generated, URL.
Real example for ChatGPT
"Response to the prompt 'Summarize the main causes of the French Revolution in three paragraphs.'" ChatGPT, GPT-5, OpenAI, 28 Apr. 2026, chat.openai.com/share/abc123.
In-text citation
You do not have an author, so use a shortened version of the description in parentheses: ("Response to the prompt 'Summarize the main causes'"). Keep it short enough to read but specific enough to find the right entry on your Works Cited page.
If you used AI for multiple prompts in the same paper, each one gets its own Works Cited entry. That sounds like a lot, but it is the cleanest way to show exactly what came from where. If you only used the same chat session over and over, one entry covers it as long as the URL points to the full thread.
Citing AI is not an admission of cheating. It is the same move you make for any other source: tell the reader where this came from so they can judge it.
How to cite AI in APA 7 format
APA treats the company that built the tool as the author, since the company is the legal creator. This is the biggest difference from MLA. As of the September 2025 update, APA also wants you to cite the specific chat, not just the tool itself, when a shareable URL exists.
APA template with shareable URL
Company. (Year, Month Day). Title of the chat or short description [Generative AI chat]. Tool Name. URL
Real example for ChatGPT with shareable link
OpenAI. (2026, April 28). Causes of the French Revolution summary [Generative AI chat]. ChatGPT. https://chatgpt.com/share/68a77b60-0ee4-800c
Template when there is no shareable URL
Company. (Year). Tool Name (Version) [Large language model]. URL of the tool.
Real example without a shareable link
OpenAI. (2026). ChatGPT (GPT-5) [Large language model]. https://chat.openai.com
In-text citation
Use (OpenAI, 2026) or (Anthropic, 2026) for Claude. If you are quoting the AI directly, treat it like a personal communication and add the chat title or description: (OpenAI, 2026, "Causes of the French Revolution summary").
The other thing APA wants, and this gets missed a lot, is a sentence in your Method section or paper body explaining how you used the tool. Even just one line: "I used ChatGPT (OpenAI, 2026) to generate three possible thesis statements before drafting." That sentence is what most professors are actually looking for.
How to cite Claude, Gemini, and other tools
The same rules apply to every chatbot, but the company name and product name change. Use this quick reference and just swap in your tool.
Claude (Anthropic)
MLA: "Response to the prompt 'Compare classical and operant conditioning.'" Claude, Claude Opus 4, Anthropic, 28 Apr. 2026, claude.ai.
APA: Anthropic. (2026, April 28). Compare classical and operant conditioning [Generative AI chat]. Claude. https://claude.ai/share/your-link
Google Gemini
MLA: "Response to the prompt 'Explain the second law of thermodynamics.'" Gemini, Gemini 2.5 Pro, Google, 28 Apr. 2026, gemini.google.com.
APA: Google. (2026, April 28). Second law of thermodynamics explanation [Generative AI chat]. Gemini. URL
Perplexity
Perplexity is a little different because it cites real sources. If Perplexity's answer is built from articles, cite the original articles, not Perplexity. Use Perplexity itself only when you are quoting its own synthesis or when no underlying source is shown.
NotebookLM
NotebookLM is interesting because it only summarizes what you uploaded. The convention forming in 2025 and 2026 is to cite the original source documents you uploaded, then add a methods note that says you used NotebookLM to generate the summary or audio overview.
The methods or acknowledgment note that saves you
Even with a perfect Works Cited entry, professors increasingly want one short paragraph explaining how AI fit into your process. This is the single most useful thing you can add to a paper, and most students still skip it.
Where to put it
If your paper has a Methods section, put it there. If it is a humanities essay with no methods section, add it as a footnote on the first page or as an Acknowledgments line at the end. APA recommends the Method section. MLA leaves it open.
What to write
Three sentences max. Cover what tool you used, what you used it for, and what you did with the output. Example:
"I used Claude (Anthropic, 2026) and ChatGPT (OpenAI, 2026) during this paper. Claude helped me brainstorm three possible thesis statements before I picked the final one. I used ChatGPT once to clarify my second body paragraph, then rewrote the suggested version in my own words before including it."
That paragraph does more for you than any Works Cited entry. It shows the grader exactly what was generated, what was rewritten, and what was original. If a detector flags a sentence later, this note is your defense. If you are submitting to a class that uses Turnitin's AI report, the note is what graders compare the report against.
Save the chats
Whatever tool you use, click Share and save the link. Or download the conversation as a PDF. Keep it for at least a year. If your school questions a paper after the semester ends, you want proof you can pull up in two minutes, not a vague memory of what you typed in.
Common citation mistakes students still make
A few patterns show up over and over in 2026, and most of them are easy to fix once you know what to look for.
Citing the tool but not the chat
This was fine in 2023. It is not fine now. Both MLA and APA want a description of the specific chat or prompt. A reference that just says "ChatGPT, OpenAI, 2026" without describing what was generated is treated as incomplete.
Listing the AI as the author
In APA, the company is the author. In MLA, there is no author at all. Putting "ChatGPT" in the author slot will get marked wrong on most rubrics that check citation format.
Forgetting to cite when you only "edited" with AI
If you fed your paragraph into ChatGPT and pasted back the rewritten version, that is generation, not editing. It needs a citation or a methods note. True editing is more like Grammarly catching a comma. Anything that changes structure, word choice across a sentence, or paragraph flow should be disclosed.
Using a fake URL
Do not invent a URL to make a citation look complete. Use the real shareable link or the tool's homepage if no share link exists. Made-up URLs get caught fast and look much worse than admitting the tool did not give you one.
Citing AI summaries as if they were the original source
If you used ChatGPT to summarize a study, cite the original study, not ChatGPT. AI is a research helper, not a primary source. The same goes for Wikipedia, Khan Academy explanations, and any other secondary summary. Always trace back to the actual paper or article.
FAQ
Do I have to cite AI if I only used it for grammar?
If you used a tool that only catches grammar and spelling, like Grammarly's basic checker, you usually do not need to cite it. If the tool rewrote sentences for tone, structure, or word choice, you do. The line is whether the words changed in a way that affects meaning. When in doubt, add a one-line acknowledgment in a footnote.
What if my professor said "no AI" but I used it for brainstorming?
You should not have used it, even for brainstorming, if the policy was no AI. Talk to your professor before submitting. Honesty before the deadline almost always lands better than discovery after. Some professors will let you redo the section without the AI input. Hiding it and getting caught later is a much bigger problem than a tough conversation now.
How do I cite a ChatGPT chat that I cannot share publicly?
Use the APA format for tools without shareable URLs: OpenAI. (2026). ChatGPT (GPT-5) [Large language model]. https://chat.openai.com. Then add a methods note describing the prompt and what you used the response for. Save a screenshot or PDF of the chat for your own records in case you need to prove it later.
Is it okay to use AI for outlines if I cite it?
In most classes, yes. Outlining is one of the most accepted uses. Cite it the same way you would any other AI use, with a Works Cited entry and a one-line note saying you used the tool to generate an outline. Some professors specifically allow this and ask you to attach the outline as an appendix.
Do MLA and APA treat AI differently for high school papers?
The format is the same. The expectation is sometimes lower. Most high school teachers care more about whether you disclosed the use than whether your bibliography entry follows MLA 9 to the letter. Use the right format if you can, but the methods note matters more than punctuation.
What about citing AI in a lab report or science class?
Science classes usually use APA or a journal-specific style. Follow APA's format above and add a clear note in the Methods section. Be especially careful about citing AI for data analysis or interpretation, since that is where most science professors draw the line.
What to do today
Three takeaways. First, find your professor's AI policy before you write a single sentence, because the format follows the policy, not the other way around. Second, learn one citation format well, MLA or APA, and just swap the company and tool name for any chatbot. Third, write a three-sentence methods note for every paper where AI touched the draft, even if your professor never asks for one.
The single best move you can make today is to open the next paper you have due, find the AI section of the syllabus, and write down what is allowed in your own words. Then if you do use a tool, save the share link as you go.
