Press Cmd twice to control your browser, take notes, message on Slack, or talk with AI about what you’re seeing — all without leaving the page. Lyncx is a unified interface for everything you do online.

I built Lyncx because I wanted a faster, smarter way to use the web. You can manage tabs, send emails or Slack messages, watch YouTube videos, talk to AI, write notes or edit your calendar — all without ever leaving your current tab. With over 30 commands, it brings everything you do online into one interface. Beyond control, Lyncx also gives you awareness. It tracks how you browse, where your time goes, and how pages connect, helping you understand your habits and optimize your workflow — all done locally for speed and privacy. It feels like having one seamless workspace that helps you move faster, stay organized, and understand where your time goes.

I recently tried Lyncx, and I have to say it’s by far the best browser extension I’ve used in a long time. As a huge shortcut enthusiast who relies on Vim for programming and Notion for note-taking, I’ve always struggled to carry that same level of productivity onto the web. I switched to Cursor because I was tired of constantly copy-pasting my code into Claude or ChatGPT, which is why I love how Lyncx lets me seamlessly provide webpage context to an LLM. It’s perfect for people like me who don’t want to switch to a dedicated AI browser (Atlas, Dia, Comet, etc.) but still want the same powerful features. Another thing I really appreciate about Lyncx is the ability to take notes on a webpage and retrieve them anytime. I didn’t realize how helpful that would be until I started using it. Keep up the great work, An! I’m excited to keep using Lyncx and see how it evolves.
