Browser extension
The extension works on any page on the web, whether or not you have saved it. It opens a Winda sidebar beside the page, where you can save the page, chat about it, and make flashcards from it.
Winda for Chrome is in the Chrome Web Store. Sign in with the account you already use. Your library, folders, and credits are the same on both sides.
The sidebar
The sidebar opens beside the page you are on, and it works whether or not you have saved the page.
You can save the page into your library. Winda reads it from your tab instead of fetching it, so saving works behind a login or a paywall.
You can chat about the page without saving it. You can also select a passage to ask about it, annotate it, or turn it into a flashcard. An annotation made here is temporary: it is gone when you reload the page, and nothing is written to your library. Annotations in the reader are kept.
Privacy
Chats in the sidebar are not stored on Winda’s servers and are not used to train anything. The history stays in your browser, so a chat exists only on the machine where you had it.
