# CV Builder

> Free, private resume editor that runs entirely in your browser. No account required — data stays in localStorage on the user's device until they export or share it.

CV Builder is a client-side progressive web app for creating professional CVs/resumes. Users edit structured form fields, preview live with one of five print-oriented templates, and export to PDF (browser print) or JSON (single resume or multi-CV library bundle). Optional AI flows copy schema-aware prompts to external LLMs (ChatGPT, Claude, Gemini, Grok); users paste returned JSON back via Import.

**Privacy:** No backend, no authentication, no cloud sync. Resume content is never sent to a server by the app itself. External AI sharing is user-initiated (clipboard + paste only).

**Templates:** `classic`, `modern-sidebar`, `corporate-band`, `minimal-mono`, `rirekisho` (Japanese 履歴書-style; supports optional Personal Details section).

**Resume JSON (`ResumeDocument`):** `version`, `cv_id` (UUID), `templateId`, `libraryLabel` (sidebar name, independent of `name`), `name` (`first`, `last`, `title`, optional `photoUrl`), and `sections[]`. Each section has `id`, `type`, `heading`, `visible`, and `data`. Section types: `CNTC` (contact), `SUMM` (summary, markdown-lite), `SKLI` (skill groups), `EXPR` (work history with bullets), `EDUC` (education), `LNGG` (languages, optional proficiency %), `PERS` (optional freeform label/value rows — rirekisho only).

**Import/export:** Single resume exports as plain `ResumeDocument` JSON. Multiple CVs export as `{ kind: "cv-library", cvs: [...] }`. Import merges by `cv_id` or can replace the active CV in place.

**AI Assistant (edit):** Copies full active resume JSON (`photoUrl` stripped) plus task instructions to clipboard, opens external LLM. User pastes returned JSON via Import → Paste backup.

**Convert with AI (import):** Copies schema rules and a randomized example skeleton only — no user resume content. User provides source resume in the external chat, then imports returned JSON.
