Frameworks, practice cases with worked solutions, an instant case analyzer, and verified casebooks from Indian B-schools and global universities. Built for consulting interviews, free for every student.
Describe a business problem — get the right framework, approach, and solution steps explained simply.

This is a rule-based study guide, not a live AI model. It matches your problem to one of 7 common case types (profitability, market entry, M&A, pricing, growth, market sizing, operations) using keywords, then recommends the framework chain and step-by-step approach from standard consulting methodology — the same structures McKinsey, BCG, and Bain teach (hypothesis-driven thinking, MECE, issue trees). It adapts advice for your chosen geography, because regulation, market norms, and common pitfalls differ between India, the US, and the UK.
Interview formats: McKinsey interviews are typically interviewer-led (they guide the structure), while BCG and Bain are typically candidate-led (you drive the framework) — though formats often vary by role and office. This tool trains you for both.
frameworks used in real consulting — from must-know core to rare situational tools. Each one shows when to use it, the steps, and where it comes from. 30 include a clickable link to the original source; the rest cite the original book or paper (more links coming).
Every link below was opened and checked. PDFs download directly; firm pages contain the practice case and its official suggested answers.
Cases you have opened, solutions you have checked, and analyzer runs. Saved to your account in the cloud, visible only to you. Highlights/underlines in the reader stay on this device.

No prior knowledge needed. This path explains what a case interview is, walks you through one simple solved example, and shows you exactly what to do next.
Consulting firms (and many B-schools) test you with a business problem instead of quiz questions. The interviewer describes a situation - "a company's profits are falling" or "should we launch in a new city?" - and you think through it out loud. There is no single right answer. They are watching how you structure your thinking, whether you ask good questions, and whether your recommendation follows from your analysis.
See how a real case answer is structured - in plain language, no jargon.
Open the Case Library, pick any original case, attempt it, then check the worked solution.

The case: A chai stall near a college sells tea for ₹10 per cup and sells 3,000 cups a month. Monthly costs: rent ₹8,000, ingredients ₹4 per cup, helper's pay ₹6,000. The owner asks: "How much am I actually making, and how do I make more?"
How a consultant thinks through it:
That is the whole game: define the question, break it into parts, do the math out loud, end with a clear recommendation. Every big case is this pattern with more branches.

How each part of Case Cracker works, honestly - including what it can't do yet.
Yes. Every section - frameworks, cases, analyzer, resources - is free to use, no card needed.
No. Everything works without logging in. With a free account, your case history and progress are your case history (cases opened, analyzer runs, solutions viewed) is saved to your account in the cloud, visible only to you after login - it follows you across devices. Highlights and underlines are different: they are stored only on the device where you made them, separately per account on that device, and are never uploaded. Accounts are being rolled out - if login isn't available on your device yet, nothing else is affected.
It is a rule-based study guide, not a live AI. It matches your problem to one of 7 common case types using keywords, then recommends frameworks and steps from standard consulting methodology. It runs entirely on your device - your text is not sent anywhere. Limit: keyword matching can misclassify unusual or mixed cases, so treat its output as a starting structure, not gospel.
"Take a photo" opens your camera (on phones) and "Upload an image" picks a file. The text is read on your own device - the image is never uploaded. It works on clear printed text; handwriting is not reliable.
Two kinds: official free practice cases from firm websites (linked, with solutions on the firms' own sites), and original fictional practice cases written for Case Cracker - always labeled "original".
Ask a doubt about a specific case and get a simple explanation that uses that case as context, inside the app. It is currently in private testing on selected accounts; answers can be wrong, so the worked solution stays the checked reference.
Only you. Progress is stored per-account with per-user access rules enforced by the database. When you're logged out, nothing is saved at all.
