Scholars
Research, without the friction.
Reach the resources you need from anywhere, keep every PDF and reference in one place in the cloud, and collaborate with your team — no installs, no busywork.
Everything in one place
Sign in without a password
On a supported publisher, a "Portium sign in" suggestion appears and your institutional access is passed through securely — one tap, no separate registration, nothing to install.
Good to know
No. You sign in once with the institutional SSO you already use; when a publisher is supported, a "Portium sign in" suggestion appears and access is passed through securely — no separate registration.
Run your research in shared projects
One shared workspace for references, annotations, bookmarks, and files — always in sync with your team.
Reveal the Portium toolbar from any publisher page — just hover the top edge of any site you're reading and the bar drops in. Your whole workspace, one hover away, with nothing to install.
Good to know
Yes. Resources are linked into projects rather than copied, so the same reference, highlight, or file can belong to many projects at once — and removing it from one never deletes it.
Build a reference library that cites itself
Save any paper straight from the navbar — Portium reads the DOI or PMID and pulls clean metadata for you, storing the PDF and snapshot encrypted. Every reference is searchable in My Library, ready to cite in 7,000+ styles or drop into a project.
Good to know
Portium resolves metadata server-side from CrossRef and PubMed (by DOI or PMID) and from the page's citation tags, storing clean CSL-JSON — so most saves are accurate without any hand-editing.
Highlight and annotate anywhere
Select text on any page or PDF to highlight it and attach a note — no browser extension. It reappears every time you return, and link it to a project so teammates see it in their own colour.
Good to know
Highlights re-anchor with multiple strategies, so they reappear even after a site re-renders or shifts its layout — and they load automatically the next time you open the page.
Bookmark pages with personalised suggestions
Keep any page worth returning to — organised in folders and one keystroke from found. Portium learns what you keep coming back to and resurfaces personalised "smart picks", so the pages you actually need are suggested for you, ready to save or link into a project.
Good to know
Smart picks are personalised to you — Portium surfaces the pages you revisit and the ideas you keep returning to, so the most relevant pages are offered first rather than a generic list.
