JobTracker — AI-Powered Job Application Tracker

A Chrome extension that tracks your job applications, auto-reads Gmail to update statuses, and uses AI to prepare you for every interview.

All data stays in your browser. No server. No sign-up.

---

Quick Start

git clone https://github.com/YOUR_USERNAME/jobtracker.git
cd jobtracker
npm install          # downloads PDF/Word resume parsing libs (optional)

Then in Chrome:

1. Open chrome://extensions → enable Developer mode
2. Click Load unpacked → select the jobtracker folder
3. Open Settings → paste your Claude API key

npm install is optional — it downloads the libraries needed for PDF and Word resume upload.
If you skip it, you can still paste resume text manually in Settings.

Navigate to any supported job listing page and click the JobTracker popup → Save Job. The extension scrapes the JD automatically.

Interview Prep

Open any saved job → click Interview Prep. The analysis runs automatically (30–60 seconds). Results are cached — reopen instantly next time.

Resume upload

Settings → Resume section → drag & drop or click to upload PDF/Word, or paste text directly.

• All job data is stored in chrome.storage.local on your device

• AI calls go directly from your browser to Anthropic's API using your own key
• Resume text is stored locally only
• Removing the extension deletes all data
