Benefits of Using AI Case Interview Prep Tools
AI tools are a valuable addition to your case interview toolkit. They offer flexible, low-pressure, and high-volume ways to practice core skills. But they aren’t a replacement for real feedback, human interaction, or the emotional nuance of live interviews.
The best approach? Combine AI with mock interviews, case books, and coaching. Use AI to build reps and boost confidence, but rely on real people to build judgment, polish communication, and prepare for interview dynamics.
Here are the best ways to leverage AI in your case interview prep:
On-Demand Brainstorming and Ideation
In consulting case interviews, brainstorming refers to generating a list of logical, structured ideas in response to an open-ended business question. For example, you might be asked: “What are possible reasons a retail bank’s profits are declining?” or “How could a food delivery platform grow its revenue over the next year?”
Coming up with creative, structured ideas under pressure is one of the hardest parts of a case interview. AI can provide brainstorming prompts and help you pressure-test your thinking. It can help you train your idea generation muscle.
You can use AI to test and refine your MECE (Mutually Exclusive, Collectively Exhaustive) structures. For example, ChatGPT can show you ideas and frameworks you haven’t considered, and help you expand on your initial thinking. You’ll often get suggestions to add depth or restructure the logic. It’s a great way to go from average to excellent.
Example AI prompts:
- “I’m doing a profitability case for a retail bank. Here is my current framework [insert your ideas]. What other factors should I explore?”
- ““How would you improve this framework for a new market entry case targeting Gen Z consumers in the skincare industry?”
Industry Primers and Business Context
This is an underutilized way to leverage AI. Ask for a crash course on industries you’re less familiar with. While it won’t replace deeper research, it’s a fast way to build surface-level fluency before a case.
Example AI prompt: “Give me a quick overview of the mining industry and key profitability drivers.”
Summary and Synthesis Practice
At the end of a case, many candidates struggle with summarizing insights and recommending a next step. Use AI to help build muscle memory around clean synthesis.
Example AI prompt: “Here’s the case prompt and my notes. How would you synthesize this into a recommendation?”
Volume of Practice
Need to generate 10 different market sizing questions to practice estimation drills? AI’s your best bet. It can quickly create case types tailored to your level, goals, or industry preferences.
24/7 Availability
AI tools don’t sleep. Whether you’re prepping at midnight or in short time slots between classes, they’re available. This makes AI ideal for candidates balancing busy schedules, without relying on a peer’s schedule.
5 AI Case Interview Prep Tools To Consider
1. ChatGPT (General)
ChatGPT remains one of the most flexible and widely used tools for case interview prep. Use it to generate customized case prompts, refine MECE frameworks, and summarize key takeaways from practice sessions.
To make the most of ChatGPT, treat it like a coach. Instead of asking for an “airline-industry case,” try prompting it with something more specific, like: “Generate a profitability case for a regional airline facing post-COVID headwinds. Include 3 follow-up questions a MBB interviewer might ask.”

2. ChatGPT Custom Chatbots
While the general ChatGPT interface is powerful, some creators have developed custom GPTs designed specifically for consulting case practice. These bots come with built-in prompts, industry-specific case types, and sometimes even guided scoring or structured feedback. Since they’re hosted within ChatGPT’s environment, they’re also easy to access and customize based on your practice needs.
Two popular options include:
- MBB Consulting Case Coach, which helps simulate cases in an MBB-style format
- Case Interview with CaseWiz, which walks you through cases step-by-step and encourages interactive responses
3. MBB.AI
MBB.AI simulates a wide range of case types, including market sizing, profitability, revenue growth, and strategy. Each case comes with structured guidance and prompts, helping candidates understand what a strong response might look like at each stage of the case.
This tool is particularly valuable for intermediate-level candidates who want a more realistic and focused experience. Because MBB.AI mirrors the pacing and content of actual MBB interviews, it can help you practice navigating interviewer-led formats with greater confidence.
4. CaseWiz
CaseWiz.AI blends AI-generated case content with step-by-step guidance, offering a more interactive experience than traditional casebooks. The AI assistant walks you through each step in the case, from asking clarifying questions to framework building, analysis, and synthesis.
This tool is a solid option if you’re looking for more structure than an open-ended prompt, especially in your early- or mid-stage prep
5. PrepBuddy
PrepBuddy was built by ex-McKinsey consultants who saw the value in a smarter, more flexible way to practice casing. Designed to mirror real case interviews, PrepBuddy draws from actual cases used at top firms.
Unlike generic AI tools, PrepBuddy’s algorithms are fine-tuned by former consultants to evaluate not just your logic, but also how you communicate your thinking. As you walk through a case, the AI offers targeted, constructive feedback to help you improve your performance over time.

CAUTION! Be Aware of the Limitations of AI Case Interview Tools
Despite all these benefits, AI tools are not a silver bullet. If you rely on them too heavily or use them without context, you risk creating blind spots in your prep. You wouldn’t want that to cost you the chance to land your dream consulting job.
AI Case Prep Is Not a Substitute for Human Feedback
AI tools can simulate case prompts, but they can’t replicate the interactive pressure of a live interviewer. Practicing with real people helps you manage nerves, improve communication, and build confidence. Plus, live case partners can challenge your thinking, ask follow-up questions, and give tailored feedback.
AI Can’t Assess Your Communication Skills
Consulting firms don’t just test your logic during case interviews. They’re evaluating how you communicate, lead, and interact. AI tools won’t tell you if you come off as nervous, robotic, or overly verbose.
You need real-time feedback to improve your tone, pacing, eye contact, and ability to engage the interviewer.
Overly Generic Feedback
Most AI-generated feedback tends to be encouraging and vague: “Nice work! You showed structured thinking and good business intuition.”
That’s validating to hear but not useful. AI often isn’t good at pointing out where your logic is flawed, where your math skipped steps, or why your recommendation wasn’t actionable.
Beginner-Level Case Complexity
Even the most sophisticated AI tools tend to give you predictable case types and frameworks. You’re unlikely to get nuanced curveballs or multi-layered twists that reflect real consulting cases. AI is great for learning the basics, but you’ll need higher-level cases to sharpen advanced problem-solving skills.
No Calibration for Interview Dynamics
AI won’t help you manage interviewee-led cases, where you’re expected to lead the conversation and respond dynamically. It also won’t react if you’re going down the wrong path, something a real interviewer will push back on.
3 Tips To Leverage AI Case Interview Tools
1. Learn How to Talk to AI
The quality of your output depends entirely on the quality of your input. Generic prompts like “Give me a case in banking” will yield generic results.
Treat the tool like a coach you can have a two-way conversation with. The more context and structure you provide, the more useful and realistic the AI’s responses will be
2. Use AI for Targeted Skill Development & Repetition
AI can be especially valuable when you want to isolate and improve a specific part of your performance, whether that’s structuring, synthesis, or mental math. Instead of running through full cases every time, design focused drills to shore up your weak spots.
For example:
- Practice writing 5 different opening frameworks for the same case prompt
- Deliver 3 different recommendations for the same scenario and ask the AI to critique them
- Use AI as a calculator buddy to simulate fast-paced math drills (e.g., growth rates, break-even analysis, percentages)
- Test your ability to brainstorm under time pressure by asking AI to give you a random prompt and setting a 2-minute timer to generate structured ideas
- Take a case prompt and only practice one element, like market sizing or risk identification, then ask AI how your answer compares to common approaches
3. Use AI as a Supplement, Not a Replacement for Coaches and Case Partners
AI case tools are best used to augment your prep. They’re ideal for solo practice and quick reps, but they can’t replicate the experience of working with a real case partner or coach. Coaches know what the bar to land a consulting offer looks like and can guide you to meet that bar.
Aim to balance your preparation across different formats:
- Peer mock interviews for real-time pressure and feedback
- Case books from top schools for real-life cases and their answers
- Coaching sessions for insights tailored to your areas of weakness and strategies to improve your case
Remember: when you’re actually on the job, you’ll be working with people. Developing your interpersonal and communication skills through live practice is essential, even in an increasingly AI-enabled workplace.
