What it is

CaseLab: A dedicated case interview trainer built by ex-MBB consultants.
CaseLab vs ChatGPT
CaseLab vs ChatGPT for case interview practice
ChatGPT and Claude can tell you what a case interview is. What they cannot tell you is what a real MBB interview actually feels like, how interviewers calibrate and score you, or the one specific fix that turns a good answer into an offer — and they cannot run a live voice case or coach you across sessions. That is the difference between reading about case interviews and training to pass one.
First full case free. No credit card required.
Short answer
General ideas, or the training that gets the offer.
Short answer: ChatGPT and Claude are general-purpose AI tools. Ask them about case interviews and you get competent, generic explanations — what a framework is, how a case is broadly structured. What they cannot give you is what actually earns an offer. They do not know how real MBB interviews run or how interviewers calibrate performance; they cannot run a live, realistic voice case; they do not coach you across sessions or track your weak spots; and they improvise generic prompts instead of hand-crafted cases spanning the range you will actually face. CaseLab is a dedicated case interview trainer built by ex-MBB consultants: live voice simulations, feedback calibrated to how interviews are really scored, coaching that compounds across sessions, and hand-crafted cases covering every type you will see. Use ChatGPT to read up on the topic; use CaseLab to train to stand out.
Side by side

CaseLab: First full case free; then a one-time $299 for unlimited cases over 12 months.
Best for
ChatGPT: Getting oriented and reading up on the topic.
CaseLab: Training to perform — and getting the offer.
Where ChatGPT genuinely helps
What ChatGPT is good at.
Learning the vocabulary
A fast, free way to get frameworks and terms explained when you are starting out. For understanding what a case interview involves, it is a solid first stop.
Generic practice material
It will generate case prompts and math questions for as long as you keep asking — useful raw volume in the early days, even if the quality is uneven.
Instant, on-demand answers
Ask 'what is a profitability framework?' at any hour and get a clear, if generic, explanation. No scheduling, no cost.
Where CaseLab is built for the interview
What a purpose-built simulator adds.
Live, realistic voice simulations
CaseLab runs a full spoken case with an AI interviewer that drives the conversation, drops exhibits and math, and pushes back — the realistic rep a text chatbot simply cannot produce.
Insider-calibrated feedback
Built by ex-MBB consultants, CaseLab scores you the way real interviews are scored — not generic encouragement, but the specific fixes that separate an offer from a ding.
Coaching that compounds across sessions
CaseLab remembers every case, tracks the weak spots that keep recurring, and tells you exactly what to work on next. A fresh chat starts from zero every time.
Hand-crafted cases across the full spectrum
A library of cases built to cover the range you will meet in real interviews — profitability, market entry, growth, pricing, M&A, sizing, and more — not improvised prompts of uneven quality.
CaseLab vs ChatGPT FAQ
Questions candidates ask about ChatGPT for case prep.
Can I just use ChatGPT to prepare for case interviews?
You can use it to learn the basics — frameworks, terminology, generic practice prompts. What it cannot do is show you what a real MBB interview is actually like, how interviewers calibrate and score you, or the specific fixes that make you stand out — and it cannot run a live voice case or coach you across sessions. For getting oriented, yes; for training to actually pass, you need more.
What can CaseLab do that ChatGPT and Claude cannot?
Run a live, realistic voice case end to end; give feedback calibrated to how real interviews are scored rather than generic tips; coach you across sessions by tracking your weak spots and naming the specific fix; and put you through hand-crafted cases covering the full range you will face — all built by ex-MBB consultants. General AI assistants do none of these.
Is ChatGPT's case feedback good enough to stand out?
It tends to be generic and inconsistent — over-generous, occasionally invented, and full of tips anyone could get. Standing out in an MBB interview takes feedback calibrated to how interviewers actually score performance, plus the specific personal fixes that separate an offer from a ding. That is what CaseLab is built to give.
Do I still need CaseLab if I already use ChatGPT?
If your goal is to understand case interviews, ChatGPT is enough. If your goal is to stand out and get the offer, you need realistic live practice, insider-calibrated feedback, and coaching over time — the training a general assistant cannot provide. CaseLab's first full case is free, so you can feel the difference yourself.
