Esper Library: Free BYOAI Resume Engine

About

Esper Library offers a no-cost resume builder and an AI-powered cover letter creator, producing career documents optimized for applicant tracking systems. Its unique feature is the byoai (bring your own ai) model, which minimizes operational costs, enabling the site to potentially remain free indefinitely. Users can either upload an existing resume or create new content, connect their chosen AI, and then generate documents. The platform automatically manages professional formatting to deliver a polished PDF.
