Sendpaper puts a button in Safari that sends whatever you're reading straight to your reMarkable โ€” no cables, no email-to-yourself, no copy and paste. Hit the toolbar button on any article and it arrives as a clean, reflowable EPUB: just the text and images, with the ads, sidebars, popups, and clutter stripped away. It's the reading experience e-ink was made for. A SMARTER READER Sendpaper recognises the site you're on and extracts exactly the right content, so pages that never used to convert well now come through beautifully: โ€ข AI chats โ€” send a ChatGPT, Claude, or Gemini conversation and read the whole thread as a document, every prompt and reply in order. โ€ข YouTube โ€” send a video and get its full transcript as an article, complete with the title, channel, and chapter headings. โ€ข Discussions โ€” Reddit threads and Hacker News posts arrive readable and structured. โ€ข Reference & news โ€” Wikipedia, Substack, and major news sites convert faithfully, with proper headings and images. โ€ข Everything else โ€” any ordinary article is cleaned up and reflowed automatically. PRIVATE BY DESIGN Pages are converted right on your device and sent straight to your own reMarkable account. There's no Sendpaper server in the middle reading your pages, and no account to create with us. HOW IT WORKS 1. Pair once with your reMarkable using a one-time code (the same secure device-pairing the official apps use). 2. Open any article, tap the Sendpaper button, and it syncs to your reMarkable. 3. Pick it up on your device and read. Works on iPhone, iPad, and Mac in Safari.
