Case study analyses are common in business, nursing, education and law-related courses: you read a real or realistic situation, identify the key problems, analyze them with course concepts and recommend what to do. AI can help you understand the case, research background and polish your writing, but the analysis and recommendations must be your own.
Check your course's AI policy before using AI on a graded case analysis. Case analyses are graded on your reasoning. Many instructors don't allow AI-written analyses, so use AI for understanding and research where allowed, verify every fact, and disclose AI use when required.
How to Write a Case Study Analysis with AI, Step by Step
1
Read the case twice
Read once for the story and again to note facts, numbers, stakeholders and problems.
2
Ask questions about the case
Upload the case to Gemini Notebook and ask about details you missed; its answers cite the exact passages.
3
Identify the core problem
Separate symptoms from the main issue and write it in one or two sentences.
4
Research background
Use Perplexity for background on the company, industry or setting, and open the sources it cites.
5
Apply course frameworks
Analyze the case with the models your course uses, such as SWOT or a clinical framework, using evidence from the case.
6
Develop recommendations
Propose realistic options, weigh pros and cons, and justify your choice with evidence.
7
Write and polish
Write the analysis yourself in the required format, then use Grammarly for clarity and errors.

#1
Gemini Notebook (formerly NotebookLM)
Best for: understanding every detail of the case
Google renamed NotebookLM to Gemini Notebook in July 2026. You upload your own sources — documents, readings, PDFs — and it answers questions using only those sources, with inline citations that jump to the exact passage. It can also turn your sources into quizzes, flashcards and audio overviews. The free plan allows up to 100 notebooks with 50 sources each, and higher Google AI plans raise those limits. Google is offering eligible US college students a free year of Google AI Pro if they redeem by December 31, 2026 (a payment method is required and the plan renews automatically).
Why students use it:
Answers stay grounded in the sources you upload
Citations link to the exact quote
Makes quizzes, flashcards and audio overviews from your readings
Generous free plan
Downside: It only knows what you upload, and Google itself notes it can make mistakes — it can't judge a source's context, bias or authorship the way a historian does.
#2
Perplexity
Best for: background research with sources
Perplexity is an AI search engine that writes answers with numbered citations to the web pages it used, which makes it a fast way to get background on a company, competitor or industry before you dig into a case. The free plan includes unlimited basic searches and a small daily allowance of Pro searches. Perplexity Pro costs $20/month, and verified students can get Education Pro for $10/month (verified through SheerID).
Why students use it:
Every answer shows clickable sources
Half-price Education Pro for verified students
Useful free tier for quick research
Downside: It summarizes web pages, which may be outdated or promotional — for financial figures, go to company filings, your library's business databases or the original source.
#3
ChatGPT
Best for: explaining frameworks and testing your reasoning
ChatGPT can explain engineering concepts, walk through problem setups and help debug code. Study mode, available on the Free plan, guides you with questions and step-by-step help instead of handing over answers. Plans: Free, Go ($8/month in the US) and Plus ($20/month). Through October 31, 2026, eligible US college and graduate students could claim four free months of ChatGPT Plus after SheerID verification; that offer has now ended.
Why students use it:
Study mode for learning, not just answers
Covers math, coding and writing lab reports
Strong free plan
Downside: It can make confident mistakes with math, units and formulas — always check results against Wolfram|Alpha, your notes or a hand calculation.
#4
Grammarly
Best for: clear, professional final drafts
Grammarly (now part of the company Superhuman) checks grammar, spelling and tone as you type in Google Docs, Word, your browser and its apps. The free plan includes corrections, 100 AI prompts a month, Authorship — which records what you typed, pasted or generated so you can show your writing process — and a Citation Finder agent that can insert up to 5 APA, MLA or Chicago citations a day. Grammarly also offers AI agents such as Reader Reactions and AI Grader, though some agents require a paid plan. Pro costs $12/month billed annually and adds 2,000 AI prompts a month, full-sentence rewrites, a plagiarism checker and an AI detector.
Why students use it:
Works inline wherever you write
Free Authorship reports to show your writing process
Plagiarism checker and AI detector on Pro
Downside: It isn't built for researching or drafting from sources, the 50% student discount is only a limited-time offer, and monthly billing for Pro costs more than annual.
#5
Microsoft Copilot in Excel (Microsoft 365 Personal)
Best for: analyzing case numbers in Excel
Microsoft 365 Personal includes the Word, Excel, PowerPoint and Outlook desktop apps with Microsoft Copilot, which can help explain and write formulas, summarize data and create charts inside Excel. It costs $9.99/month or $99.99/year, and Microsoft offers verified college students 50% off Microsoft 365 Personal (you re-verify student status each year). AI credits and feature limits apply.
Why students use it:
Works inside Excel, the tool most business courses use
50% student discount on Microsoft 365 Personal
Includes Word, PowerPoint and 1 TB of cloud storage
Downside: Copilot features come with AI credit limits, and the Microsoft 365 account your school gives you may not include the same Copilot features — check with your school before paying. Always check AI-written formulas.
Frequently Asked Questions
AI can summarize a case, but your instructor is grading your analysis and recommendations. Most courses don't allow AI-written case analyses. Use AI to understand and research, then write it yourself.
Gemini Notebook is useful for asking questions about the case document, and Perplexity helps with background research with sources. Copilot in Excel can help with case numbers.
Follow your instructor's format. Many include a summary, problem statement, analysis, alternatives, recommendation and implementation plan.
AI can explain how SWOT works, but your SWOT should be based on evidence from the case and your own judgment.
Open every source the tool cites, confirm facts and figures in original sources such as company filings, and don't rely on AI summaries alone.
