Sidelong

Turn everything you learn into writing worth reading. Save articles, videos, podcasts, and highlights to your library in one click.

Sidelong helps you turn everything you learn into writing worth reading. The extension is the capture half: one click sends whatever you have open to your library, ready for the day you sit down to write. SAVE ANYTHING IN ONE CLICK Articles, newsletters, PDFs, YouTube videos, podcasts, tweets and threads. Sidelong reads the page, transcribes any audio or video, writes a summary with key insights, and files everything searchable in your library. 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. IMPORT YOUR KINDLE NOTEBOOK Your books and highlights in one scan. No file exports, no emailing yourself clippings. CAPTURE NOTES AND IDEAS 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 and key insights in place, plus related items from your library. EVERYTHING COMES BACK WHEN YOU WRITE Your library is not a read-later pile. In the Sidelong editor, what you saved resurfaces beside your draft: highlights ready to quote, sources attached, ideas connected to what you are working on. Sidelong requires a free account.
