Oystack: Add DOI

Oystack: Add DOI helps you save research papers to your Oystack library without breaking your reading flow. When you find a paper online, the extension looks for a DOI on the current page and lets you import that paper into Oystack from the popup or an inline page button. It can detect DOI values from page metadata, DOI links, the page URL, and visible page text. Use it to: - detect DOI identifiers while reading research online - add papers directly to your Oystack library - check whether a paper is already in your library before importing it again - save papers to a selected collection or your configured default collection The extension reuses your existing Oystack web session for authentication, so there is no manual token to copy or store.
