Nexus door Cognfy LLC

Nexus is a personal bookmark manager that keeps your saved pages organized and accessible across every device. The Nexus browser extension brings capture directly into your browser: click the toolbar icon, confirm or edit the title, pick a collection and tags, and save. That's the whole flow — nothing more, nothing less.

Save without the friction. When you click the toolbar button, the extension reads the current tab's title and URL and pre-fills the form for you. You can adjust the title, add a note, assign the page to any collection in your account, and apply tags before saving. No context switching. No copy-paste. The page is saved and you're back to what you were doing in a matter of seconds.

Connected to your account. Your collections and tags are pulled from your Nexus account and cached locally so the popup opens fast. You can pick an existing collection, type a new tag, or leave the defaults and move on. Anything you save through the extension shows up immediately in your library at stash.nexus alongside everything you've added from the web app or mobile.

Private by design. The extension stores your API token in your browser's local storage, sandboxed to the extension itself. It does not run on pages you visit, does not read your browsing history, and does not send anything to any server except stash.nexus. No analytics. No telemetry. No third-party scripts. When you save a page, the only data transmitted is the URL, the title, and whatever notes or tags you typed.

Capture your Inbox. Pages saved without a destination land in your Inbox collection, which is purpose-built for triage. Review and organize them later — from the extension or the full web app — when you have time to think.

Nexus is invite-only during its current beta. If you already have an account, sign in from the extension's options page and you're ready to go. Invites are available at stash.nexus.
