How it works

Esper Library combines structured editors, BYOAI prompts, and in-browser export so you keep control of your career narrative.

  1. Generate the prompt. The builder reads your saved sections (locally) and assembles an ATS-aware instruction set for your AI.
  2. Use your AI. Copy the prompt into the assistant you trust. Your chosen model does the drafting; your API or chat terms apply.
  3. Paste back & export. Return the model output into the workspace, refine, and print or save PDF—all without uploading your resume file to Esper Library.

Your AI provider preference is remembered in this browser (res_preferred_ai) so the BYOAI modal stays consistent across resume and cover letter flows.
