Citation tools can save hours on reference lists, but AI chatbots are also known to invent sources that don't exist. This guide shows a safe workflow: use AI to find and format citations, then verify every one.
Don't ask a chatbot to write your reference list. University library guides warn that ChatGPT and similar tools can produce citations to articles that don't exist — sometimes the journal is real but the article isn't. Use a citation generator built on real source data, and confirm every source exists.
Search your library database or Google Scholar (or use an AI search tool like Perplexity to get started), and open each source yourself.
Use a tool like the Zotero Connector or a citation generator's browser extension, or add items by DOI or ISBN, so the metadata comes from the source itself.
Pick APA, MLA, Chicago or the style your instructor requires and generate the reference entries.
Compare authors, year, title, journal, volume/issue, pages and DOI. Even Zotero's own documentation says to always check saved items for accuracy.
Search the exact title on Google Scholar, check it in your library catalog, or paste the DOI after https://doi.org/ — a real DOI resolves to the work.
Use a Word or Google Docs plugin (Zotero has both) so your in-text citations match your reference list.
Compare against the official APA or MLA guide, cite or disclose any AI output you used as your instructor requires, and follow your course's AI policy.

APA 7: The APA Style blog (September 2025) treats the AI company as the author. Format: OpenAI. (Year, Month Day). Title of chat [Generative AI chat]. ChatGPT (model). URL of the shared chat. APA also asks you to describe how you used the tool.
MLA 9: MLA's guidance (updated 2025) does not treat AI as an author. Start with a description of the prompt, then the tool, version, company, date and URL. Example: "Describe the theme of nature in Jane Austen's Mansfield Park" prompt. ChatGPT, model GPT-4o, OpenAI, 23 Sept. 2024, chatgpt.com/share/…
Always check your instructor's rules — many require disclosing AI use even if you don't quote it.
