Resume Job Matcher – Chrome Extension + Website

Improve ATS alignment between your resume and a LinkedIn Job Description. Extract a JD from LinkedIn, analyze alignment, rewrite resume bullets to add missing JD skills, generate a cover letter, and proofread it — powered by Chrome’s on-device AI APIs, with an optional Gemini fallback.

Live Demo / Access

• Website: host Ext_plus_site/website/index.html on a static host (Netlify/Vercel/Cloudflare or local at http://127.0.0.1:5500/).
• Extension: load unpacked Ext_plus_site/extension in Chrome.

Problem

Job seekers struggle to tailor resumes quickly to unique job descriptions, leading to low ATS match rates and recruiter pass-through. This app automates analysis and rewriting so bullets explicitly reflect the JD and improve ATS alignment.

What It Does

• Chrome Extension Popup
  • Analyze Resume vs JD (Prompt API) → readable cards: score, missing skills, strengths, recommendations
  • Summarize JD (Summarizer API)
  • Rewrite Resume Points (opens website, transfers JD+resume via extension storage)
• Website
  • Auto-ingests JD + resume from extension
  • Chat using Prompt API; fallback to Gemini if Prompt is unavailable
  • Rewrite resume points using two-step plan → Rewriter API (few-shot-style examples)
  • Generate cover letter (Writer API)
  • Proofread with side-by-side diff (Proofreader API) and resilient Prompt fallback

APIs Used

• Chrome AI APIs:
  • Prompt API (LanguageModel)
  • Summarizer
  • Rewriter
  • Writer
  • Proofreader
• Optional fallback
  • Gemini Developer API (gemini-1.5-flash)

Project Structure

Setup

1) Website (local or hosted)

• Serve the website/ folder through a static server. For local testing, ensure the URL is http://127.0.0.1:5500/Ext_plus_site/website/index.html so the extension can connect.
• The page automatically reads data from the extension when opened with ?src=ext&extId=... and will persist the extId for resume handoff.

2) Load Extension (Manifest V3)

• Chrome → chrome://extensions → enable Developer mode → Load unpacked → select Ext_plus_site/extension.
• Open a LinkedIn job page, then click the extension icon.

3) Resume

• On the website, upload your resume (PDF/TXT). It stores a copy in localStorage and in extension storage so the popup and website stay in sync.

4) Optional: Gemini API Key (chat fallback)

If the Prompt API is unavailable on a machine, the chat will prompt once for a Gemini key.

• Get a key: https://ai.google.dev/
• When prompted, paste your key (stored as geminiApiKey in localStorage).
• Or set manually:

localStorage.setItem('geminiApiKey', 'YOUR_API_KEY');

How to Use

1. On a LinkedIn job page, open the popup:
   • Analyze Resume vs JD → see score, missing skills, strengths, recommendations
   • Summarize JD → concise, readable summary
   • Rewrite Resume Points → opens the website with JD + resume loaded
2. On the website:
   • Click “Rewrite Resume Points” → see improved bullets that add missing JD skills/tools
   • Generate Cover Letter → then “Proofread” to apply grammar/spelling fixes and view side-by-side diff
   • Use chat for guidance; falls back to Gemini when Prompt is unavailable
