I've noticed that whenever I'm on HN, I feel intrigued and want to explore more discussions. I needed an easier workflow to explore related submissions instead of googling and going back and forth. If a submission is interesting enough for me to click on, chances are I'd like to dig deeper into this topic and there are more related discussions that offer new context or perspective.

I made this browser extension that adds a section for related submissions automatically. The results are displayed in a sidebar right in the page's layout using HN native style just like other elements. I paid special attentions to UX to make it intuitive and seamless and now the extension is just part of the HN experience for me.

Implementation-wise, it integrates HN algolia search API and uses the submission title as its initial query with the ability to change the query and other options interactively.

It's available on: Chrome, Firefox, and as a userscript.

I shared it earlier last year when it was barely a prototype, at the time wasn't yet published and was only for chrome (hence the update): https://news.ycombinator.com/item?id=36102610. I've been using it daily since and I'm happy to share it now for you to give it a try.
