Choose Case Room to learn the case method through its free course and continue with targeted drills and full interviews. Choose Kasie when your priority is ongoing free full-case practice during its beta. The decision is about the preparation you need, not simply whether an AI interviewer is available.
The differences that matter
| What you get | Case Room | Kasie |
|---|---|---|
| Learning | Complete free course in six chapters | Learning through case attempts and review |
| Practice format | 200+ skill drills and full AI cases with paid access | Interviewer-led and candidate-led cases; free unlimited beta sessions |
| Feedback | Decision-specific scorecards; reasoning and delivery feedback | AI dimension scores, improvement areas and practice history |
| Main reason to choose it | Learning and regular practice without scheduling a partner | Continuing full-case practice with no beta subscription charge |
| Purchase | $29/month, $60/3 months or $100/year | Free during beta |
Kasie has the stronger offer for a candidate who already knows the method and needs a continuing supply of free full cases. Case Room’s free course is the stronger starting point for learning the method, with five drills and one case included. Choose paid Case Room access when the course-to-skill-to-case routine is what you want to continue. Kasie is free during beta, while continuing paid Case Room access includes the wider drill library.
Inside Case Room: isolate the decision you need to improve
The Case Room drill recording shows a short task that a full-case-only routine handles less directly. Physical Therapy Plan-of-Care Leakage reports evaluations up 9%, flat reimbursement and completed visits down from 8.4 to 6.2. The candidate must choose the next investigation, using the drop-off after visit three as part of the evidence.
The task is not to recite every possible cause. It is to select the most useful next cut and justify that priority. A four-minute exercise gives that decision its own practice space before it returns inside a longer case.
This example explains the reason to pay for Case Room's broader practice access. Kasie's free full cases remain a strong option for repetition; Case Room adds a course and targeted work on the components of the interview.
Quick Prioritisation Drill
A regional home-cleaning firm grew first-time bookings this year, yet revenue barely moved. The owner can fund one investigation this month.
- Cancellation timing
- Mostly straight after the first clean
| Measure | Last year | This year |
|---|---|---|
| First-time bookings | 4,000 | 4,800 |
| Cleans per customer | 5.0 | 4.2 |
| Price per clean | $90 | $90 |
Which investigation should the owner fund first to restore revenue growth?
Kasie's free beta is a meaningful offer
Kasie advertises unlimited sessions during beta, with a growing case library, feedback, history and narration. Its supported styles include interviewer-led and candidate-led cases.
The clear benefit is more independent case attempts without a subscription fee. That makes it a useful option for students and candidates whose budget would otherwise prevent additional practice.
The free offer is beta access, so its availability can change. While it is available, Kasie is the stronger budget choice for additional complete mocks.
The reason to pay is the wider routine, not access to an AI interviewer
Kasie's free beta gives candidates repeated AI case practice without a subscription payment. Its interviewer-led and candidate-led formats, feedback and history are meaningful features. It would be wrong to dismiss that offer merely because Case Room has paid plans. For a candidate whose only requirement is more full cases at zero cost, Kasie is the recommendation.
Case Room earns a paid purchase when the candidate needs its wider course-and-drill routine. The complete course is free, so the first learning decision does not require payment. Continuing paid practice then combines short exercises with full interviews, rather than making every session another complete case.
Consider someone who consistently loses direction after the initial structure. More free cases provide repetition, but the same decision can remain weak across many attempts. A prioritisation drill isolates how to select an investigation and ask for useful evidence. Case Room is the better main platform when that focused work is the service being bought.
The sensible free arrangement is also straightforward: use Case Room's course and starter practice, then Kasie's beta for additional full interviews. That does not reproduce every paid Case Room feature, and it does not need to. It is a legitimate zero-spend route for a candidate who can organise the separate resources.
The budget recommendation
Prices in USD:
| Need | Recommendation | Cost |
|---|---|---|
| Learn the fundamentals and begin practising | Case Room's course and starter practice | Free |
| Add repeated AI cases without payment | Kasie during beta | Free |
| Continue across drills and full cases | Case Room monthly | $29 |
| Use the same routine for a recruiting season | Case Room quarter | $60 |
| Keep Case Room access for a year | Case Room annual | $100 |
Case Room's free course supplies the starting curriculum in this plan. Crafting Cases is another free option for candidates who want its particular approach to teaching case skills.
Quick Case Math Drill
A climbing gym piloted a coached induction for free taster visitors. Conversion to membership rose from 10% to 14% during the pilot.
- Free taster sessions
- 2,500 per year
- Induction cost
- $8 per taster session
- Contribution per member
- $300 in the first year
If the pilot result holds, what net first-year gain does coaching every taster add?
A free beta and a paid plan create different commitments
Kasie is free during beta. That is a description of its current offer, not a promise that the same terms continue indefinitely. A candidate with interviews approaching can use the available practice now without treating future access as guaranteed. Case Room's published monthly, quarterly and annual payments make the paid preparation budget explicit.
For a six-week preparation period crossing two monthly billing periods, Case Room costs $58; a three-month purchase is $60. Choose the quarter when you want the extra time for a $2 larger upfront payment. Choose the free combination when any subscription would displace a more important expense.
For a candidate with a reliable university case group, the free course plus those partners may already cover teaching and human practice. Paid Case Room access becomes useful for the independent drills and interviews between meetings. There is no need to buy it merely to assemble a longer list of resources.
For a candidate without a partner network who needs repeated conversations with actual people, neither platform's AI format supplies that service. PrepLounge Premium's observed $69 annual USD offer is one way to add a network, while a consulting club may already provide it. See the PrepLounge comparison for the distinction between peer access and professional coaching.
Choose Case Room for the connected paid learning and practice routine. Choose Kasie during beta for repeated full cases at zero cost.
Our recommendation
Start with Case Room's free course and practice. Choose paid Case Room access for continuing preparation across lessons, drills and full interviews. Use Kasie's free beta when you specifically need more full-case attempts at no cost; that is a concrete budget advantage for that requirement.
More free full cases can be useful. Before counting attempts, test whether you can pick the next investigation and explain why it matters.

Frequently asked questions
Choosing between Case Room and Kasie
Should I choose Case Room or Kasie for case interview practice?
Choose based on the preparation you need, since both give you an AI interviewer. Case Room suits candidates who want to learn the method through a free six-chapter course, then practise with targeted drills and full AI cases. Kasie suits candidates whose main priority is more full-case attempts at no cost while its beta lasts.
Why would I pay for Case Room when Kasie's beta is free?
Pay only if you need the wider routine, not just an AI interviewer. If your sole requirement is more full cases at zero cost, the article recommends Kasie. Case Room justifies a purchase when you want its course combined with short skill drills and full interviews, so you can work on individual decisions as well as complete cases.
Can I use Case Room and Kasie together?
Yes, and that can be sensible on a tight budget. Start with Case Room's free course and starter practice to learn the method. Then use Kasie's free beta when you specifically need more full-case attempts at no cost. Add paid Case Room access later only if you need continuing drills alongside full interviews.
Kasie's free beta
Is Kasie really free to use?
Yes, for now. Kasie advertises unlimited sessions during its beta, with a growing case library, feedback, practice history and narration. The important qualifier is the word beta. It describes the current offer and does not guarantee that the same terms will continue. Treat it as genuine free practice today rather than a long-term zero-cost plan.
What if Kasie stops being free before my interviews?
Use the free practice while it is available, but do not build your whole plan on future access. If your interviews are close, the current beta is a real benefit. If your preparation runs for months, a published paid plan, such as Case Room's monthly, quarterly or annual option, lets you set the budget in advance.
Does Kasie support candidate-led cases?
Yes. Kasie lists both interviewer-led and candidate-led styles among its supported formats. That matters if you want to rehearse more than one case style. Its sessions also provide dimension scores, improvement areas and practice history, so you can see which areas need more attention across repeated attempts.
Costs and plans
How much does Case Room cost compared with Kasie?
Case Room lists $29 a month, $60 for a quarter and $100 for a year, all in USD. Its complete course and starter practice are free. Kasie currently costs nothing during its beta. Price is not the only difference. Case Room's paid tiers buy continued access to drills and full cases, while Kasie's free tier is a beta offer.
What do I get on Case Room without paying?
The free tier includes the complete six-chapter course, five drills and one full case. That is enough to learn the fundamentals and try both practice formats before you decide whether to pay. Signing in lets you save attempts and review their feedback. Paid access opens the wider set of more than 200 skill drills and further full AI cases.
Which Case Room plan makes sense for a single recruiting season?
Case Room positions its $60 quarterly plan for using the same routine across a recruiting season. The $29 monthly plan suits continuing practice, and the $100 annual plan keeps access for a year. Match the plan to how long your preparation will realistically run, and work through the free course before you commit to any of them.
Drills, full cases and feedback
What is the difference between a skill drill and a full case?
A drill isolates one decision, while a full case runs the whole interview. In Case Room's Physical Therapy Plan-of-Care Leakage drill, you see evaluations up 9%, flat reimbursement and completed visits down from 8.4 to 6.2. You then choose the next investigation. A full-case-only routine practises that single prioritisation step less directly because it sits inside a longer conversation.
What is the Physical Therapy drill actually asking me to do?
It asks you to select and justify the single most useful next investigation. It does not ask you to list every possible cause. You should use the drop-off after visit three as part of your evidence. The drill takes four minutes, so it quickly tests whether you can prioritise under pressure rather than brainstorm broadly.
How does feedback differ between the two platforms?
Case Room gives decision-specific scorecards with feedback on reasoning and delivery, so you know which call to improve. Kasie provides AI dimension scores, improvement areas and a practice history across sessions. Case Room's format focuses on individual choices. Kasie's format helps you follow broader patterns across repeated full-case attempts.
