HN Keyword Filter is a Chrome add-on developed by Feaster Javascript Development. It is a free tool that allows users to filter out unwanted stories on Hacker News (HN) based on keywords.

Tired of seeing political stories or the latest JavaScript framework in the HN list? With HN Keyword Filter, you can create a comma-separated list of words that you want to filter out. Simply click on the YCombinator logo when you're on HN, and a textarea will appear where you can enter your keywords.

The add-on persists your keywords across popup opens and browser sessions using localStorage. The filtration process occurs on page load and when the keyword list is changed, with a debounce of 1 second. Any removed stories are printed to the console.

HN Keyword Filter is a handy tool for HN users who want to customize their news feed and avoid stories on specific topics of disinterest.
