PrepBuddy

Plans start at $5 a month for PrepBuddy, which also offers a free trial, so you can try a case before paying.

PrepBuddy is an AI interview assistant for consulting case interview prep: you work through cases written by experts and get feedback on your answers as you go.

The cheapest plan, Category, limits you to cases from one category of your choice.

The $19 Monthly plan opens every case and adds a full dashboard for tracking your progress.

A 3 Month plan costs $50 and has the same features, which works out cheaper per month if your recruiting season is a long one.

A Custom plan adds custom cases and is priced by contacting the team, so it looks made for schools, groups or firms rather than individual candidates.

Every tier includes constructive feedback on your responses.

The dashboard is the main reason to move up from the $5 plan, since seeing how you improve across many cases matters more than a single score.

The freemium model means you can judge the feedback quality yourself before committing.
