Everything you learn, put to work. Save articles, videos, podcasts and highlights to your library in one click.

Sidelong is the intelligent reading and writing platform that puts everything you learn to work. The extension is the capture half. One click sends whatever you have open to your library, where Sidelong summarizes it, connects it to what you already saved, and keeps it ready for whenever you need it. SAVE ANYTHING IN ONE CLICK Whatever you have open, an article, a newsletter, a PDF, a video, a podcast episode or a thread, one click sends it to your library. Sidelong reads the page, transcribes any audio or video, writes a summary with key insights, and files it searchable alongside everything else you saved. HIGHLIGHT THE WEB LIKE A BOOK Select a passage and save it as a highlight. It lands in your library with the source attached, and when you return to the page your highlights are waiting right where you left them. SUBSCRIBE FROM THE SHOW'S PAGE Open a podcast on Apple Podcasts, Spotify or Overcast, or a channel on YouTube, and subscribe from the popup. New episodes land in your library, transcribed and summarized. IMPORT YOUR KINDLE NOTEBOOK Your books and highlights in one scan. No file exports, no emailing yourself clippings. Open any book in Sidelong and sync its highlights from there. CAPTURE NOTES Jot a thought from any page, with the page attached when you want the context kept. A POPUP THAT KNOWS WHERE YOU ARE On a saved page, the popup shows the summary, the key insights and the text or transcript in place, plus related items from your library. YOUR LIBRARY, PUT TO WORK Nothing you save is a read-later pile. Sidelong remembers it, connects it, and brings it back when it matters. A daily Spark drawn from across your library, answers grounded in what you saved with every source cited, and your highlights ready to quote whenever you read or write. Sidelong requires a free account. Create one at https://sidelong.app. Everything you learn, put to work.
