I made a Chrome Side Panel note to beat context switching
Hey HN I read and research multiple things, both for work and personal curiosity. But I realized that in doing so, I have to frequently switch among many reading tabs and note-taking pages, which breaks my reading flow. That's why I teamed up with my friends to build Saner.ai Chrome Extension. It’s a side panel note that appears across tabs, and we can toggle it on and off whenever we like. Also, we can highlight any text and then use keyboard shortcuts to save it along with its URL. This has made my reading and research experience smoother :) I hope it will be helpful to people like us out…
