Hacker News Duplicate Detector (HNDD) is a Google Chrome extension that automatically detects duplicate Hacker News (HN) submissions.
It is available from the Google Chrome Web Store: https://chrome.google.com/webstore/detail/hacker-news-duplicate-det/ocagpmnfhgbgmbaaimpehpbnnplkmpkd
To use HNDD, install the extension, and it will work automatically on relevant HN pages.
The following image shows the links produced by HNDD on a duplicate HN submission page.
A different manifest.json is used for Chrome and Firefox. For development, create a symbolic link
manifest.json that points to either manifest_chrome.json or manifest_firefox.json, depending
on the environment.
To generate zip archives, run zip.sh.

HNDD uses Algolia's HN Search API.
