JD Analyzer — AI Resume & JD Match

Tired of spending hours tailoring your resume for each job application? JD Analyzer is a privacy-first Chrome extension that helps job seekers analyze any job description against their resume — instantly. Powered by Claude or OpenAI, all data stays in your browser. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎯 WHAT YOU GET WITH ONE CLICK ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📊 Match Score (0-100) A transparent 6-dimension rubric scores your fit: • Core Skills (35 pts) • Experience Level (20 pts) • Education / Certifications (10 pts) • Industry / Domain Relevance (15 pts) • Location / Work Authorization (10 pts) • Soft Skills & Cultural Fit (10 pts) Every dimension shows a progress bar and a one-line explanation. No black box. 🎯 Interview Likelihood A SEPARATE estimate from the match score, because they're not the same thing. Accounts for real-world factors: highly competitive employer (FAANG-tier), seniority of the role, ATS-unfriendliness, and rare specializations on your resume. Itemised +/− adjustments show you exactly what's helping or hurting. 🧭 Skills Coverage Audit Every JD-required skill labelled must-have or nice-to-have, then graded present / partial / missing with the actual evidence quoted from your resume. No more "AI says I'm a 75% match" without saying which skills it counted. 📌 JD Keyword Extraction Identifies the 8-12 most important skills, tools, and concepts. ✅ Strengths Analysis Highlights what in your resume aligns strongly with the role. 📉 Skill Gap Detection Flags missing skills with priority + concrete remediation suggestion + a learning-resource link (course / book / official docs) for each one. No hallucinated URLs — links route through verified search. ✍️ Cover Letter Generator Three concise paragraphs, streamed in English with a typewriter effect. Optional "custom guidance" lets you steer the output: "emphasize my system design work", "drop the first paragraph", "keep it more enthusiastic", etc. 📝 Resume Optimization Tips 4-6 specific rewrite suggestions with exact before/after text. The ATS-friendliness score is computed deterministically at parse time — we actually inspect the source file for multi-column layouts, tables, and embedded images, instead of having the AI guess from the flattened text. 🎤 Interview Question Prediction 8 technical + 2 behavioral questions, anchored to the JD's stack AND your specific resume background. Each has a difficulty label and answer hint. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚡ NEW IN v1.2 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 👥 Multiple resume profiles Keep "Frontend", "Backend", "Manager" versions side-by-side and switch with one click in the popup. 🌏 Bilingual mode Pick English or 简体中文 for reasoning, suggestions, interview hints, and ATS explanations. Cover letter bodies stay English to match most JDs. 🌓 Dark mode System / light / dark toggle, with live preference-change tracking when set to system. 🎯 Click-to-Pick Works on ANY job site, not just LinkedIn. If auto-detection fails (or if you just prefer it), enter pick mode, hover over the JD on the page, and click it. Live character-count feedback shows whether you've selected enough. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRIVACY-FIRST DESIGN ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Your resume, JD text, and API key are stored ONLY in your local browser • Never transmitted to our servers (we don't have any) • PDF and DOCX files are parsed entirely in your browser • No analytics, no tracking, no ads ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔌 BRING YOUR OWN AI ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Choose between Claude (Anthropic) and OpenAI (GPT).
