RepoPrep parses your repository's AST, maps its architecture, APIs and data model, and labels every explanation FACT or INFERENCE — so you always know what's verified and what's a best guess. Built for interview prep and getting fast on a codebase you didn't write.
Free to start — 3 analyses a month, no card required.
@Controller('checkout')
export class CheckoutController {
constructor(private svc: CheckoutService) {}
@Post('session')
createSession(@Body() dto: CreateSessionDto) {
return this.svc.createSession(dto)
}
}POST /checkout/session is handled by CheckoutController.createSession — traced from source.
CheckoutService calls the payment gateway before writing to the ledger.
Idempotency is likely enforced via an idempotency-key header, based on naming — not confirmed by a stored contract.
RepoPrep parses code, extracts AST symbols, builds relationship graphs, and grounds every explanation in actual source files.

Interviewers love digging into your projects: “Why PostgreSQL?”, “How does auth work?”, “Where is the bottleneck?”. Answer with confidence, grounded in your real code.
“Why did you choose NestJS over a plain Express server for this backend?”
New team members shouldn't require senior engineers to manually explain hundreds of files. RepoPrep auto-documents system flows, API endpoints, file roles, and architecture decisions.
