what is prepr fr?

Prepr turns Claude Code into a personal interview coach that runs entirely on your own computer. You upload your CV and paste in a job description, and it builds a study roadmap of around six to eight topics tailored to your background and the role, then quizzes you with multiple choice questions, fill in the blank questions, and coding tasks. It grades each answer, explains what you got wrong, and links to documentation or videos to help you study further. Topics you struggle with get tracked in a review list and revisited later, while topics you handle well are moved past. The project has no built in AI model of its own. Instead it relies entirely on a locally installed and signed in copy of Claude Code to generate questions and grade your answers, which means there is no API key to manage and no per use billing to worry about. Since everything runs on your machine at the local address 127.0.0.1, your CV and your answers never leave your computer, and the files that would contain your personal data are excluded from version control by default. Setup is simple on Windows, where a single batch file starts a small local server and launches Claude Code as the coach. On other systems you run the server manually with Python's built in tools, no extra packages needed, and then tell Claude Code to run the interview coach loop. Claude Code will ask for permission the first few times it runs local commands, which is expected since it is only running the relay scripts included in the project, and this can be pre-approved with an opt-in settings file if you prefer to skip the prompts. The project requires Claude Code, Python 3.8 or newer, and a modern browser. It is released under the MIT license.
