Show HN: I built a Chrome extension to add tags and notes on LinkedIn

A few months ago, I jumped into LinkedIn for my business, but quickly hit limitations. With growing connections, it became hard to remember who was who—or where and when we’d met.

That’s why I developed a Chrome extension that lets you add tags (“circles”) and notes to your connections so you know who they are to you when they show up in your feed.

Tech stack :

- Chrome Extension Manifest V3 - Firebase Authentication - Webpack 5 build system - Vanilla JavaScript (no frameworks, keeping it lightweight for a browser extension) - Chrome APIs (Storage, Identity, ActiveTab) - LinkedIn DOM manipulation

This is my first Chrome Extension and I found it surprisingly easy to develop.

I’d love to get your feedback! Happy to discuss it with you!
