SeenDisJob: A Chrome Extension to Detect Duplicate Job Listings

Description and use

SeenDisJob is a Chrome extension that automatically detects duplicate job postings, warns users, and helps avoid repeat applications and unnecessary tabs.

Problem

Job seekers often encounter the same job posting multiple times across different sites or as reposts, leading to wasted time and accidental duplicate applications.

Outcome

SeenDisJob reduces time spent on duplicate job listings, prevents accidental repeat applications, and keeps tab sessions manageable without adding manual tracking workflow.

Workflow

• Install the extension by loading the unpacked source from GitHub via chrome://extensions
• Enable Developer mode and grant permission to read page content
• Open job listings across multiple sites; the extension detects job pages and extracts title and company
• The extension compares extracted data against local history using fuzzy matching
• If a duplicate is found, an in-page warning appears with context of previous encounter
• Users can close the tab, compare listings, or proceed as desired
• Dashboard and toolbar popup show seen jobs, duplicates caught, and recent activity

Evidence

SeenDisJob is a Chrome extension built for job seekers. Its purpose is focused and specific: it watches the job listings you open in your browser and quietly warns you when the listing on your current tab appears to be a duplicate of one you have already encountered.

Source

When you open a page that contains a job posting, the extension extracts the relevant information from the page—primarily the job title and the company name, using structured data embedded in the page where available.
