象典 Elephant Folio: PDF Library

Elephant Folio is a Personal Knowledge Management system for your PDFs. Built for researchers, students, forever learners, and anyone drowning in documents they'll never find again.

Bring a paper in from Safari, Mail, or anywhere on your device, and Elephant Folio files it for you; based on what's actually inside it, not just the filename. The folders get made. The tags get applied. You keep reading.

Rules that organize for you
Set a rule once and every matching document gets tagged automatically. Match on filename, file contents, author, and more. You can combine conditions with a simple any/all toggle. Rules run the moment a file arrives, and you can re-run them across your whole library anytime. No more tagging
one file at a time.

Set it once, stay organized forever
Build rules around the way you think, by course, by project, by client, by topic. New documents sort themselves into the system you designed, so your library stays tidy.

Smart organizing, on by default:
When Apple Intelligence is available on one of your devices, Elephant Folio can also read and tag documents on its own. 

Your documents stay yours:
Everything stays on your devices. Nothing is uploaded anywhere.

Capture from anywhere:
The Share extension works across Safari, Mail, Files, and anything else that can hand off a PDF.
Scan a physical page and it's filed before you put your phone down and your rules apply instantly.

Search that actually reaches:
Not just filenames. Not just folders. Text, tags, and document content, so the thing you're looking for turns up even when you don't remember what you called it.

One library across all your devices:
iCloud keeps everything in sync. Files live in your Documents folder and open in any app that reads PDFs. Siri Shortcuts let Elephant Folio fit inside whatever system you've already built for yourself.

No internet? No problem:
Elephant Folio is a privacy-centric, offline-first app. Capture, read, tag, and search anywhere.

The elephant never forgets. Now neither do you.
