APA's guidance on citing AI-generated content, published in March 2023 and updated since, treats AI tools like ChatGPT as software that generates content. The citation structure is relatively simple. The more complex question is when to cite AI output and what your institution requires you to disclose.

The Retrievability Problem
APA's core citation principle is that citations allow readers to retrieve the source. A private ChatGPT conversation cannot be retrieved by anyone other than you. This creates a practical challenge.
APA's guidance addresses this by recommending:
- Include the full prompt in your text — so readers understand what question generated the response
- Quote or summarize the key AI response — in your text or in an appendix
- Note that the conversation is "available upon request" — if your institution has a process for this
When You Need to Cite AI Output
Cite AI-generated content when:
- You quote AI output directly in your paper
- You paraphrase or use AI-generated content as a claim
- You used AI to generate a substantial portion of your argument
You may not need to cite AI when (depending on your institution):
- You used AI only to grammar-check or proofread your writing
- You used AI to brainstorm ideas but wrote all content yourself
- You used AI translation tools to understand a foreign-language source (you would cite the original source)

AI-Assisted Research Tools vs. AI-Generated Content
Not all AI research tools require citation in the same way:
| Tool Type | Example | Citation Approach |
|---|---|---|
| AI that generates original text | ChatGPT, Claude, Gemini | Cite the AI tool; include prompt and response |
| AI that summarizes existing papers | Perplexity, Elicit, Consensus | Cite the original papers the AI summarized, not the AI tool |
| AI-assisted search | Google Scholar AI features | Cite the papers found, not the search tool |
| AI grammar/style tools | Grammarly, Hemingway | Generally no citation needed (check your institution) |
| AI translation | DeepL, Google Translate | Cite the original source in the original language; note translation method |
