Read, annotate, and search your Zotero library on Android. Full-text PDF search, on-device OCR, and EU-hosted storage for individuals and research groups.
Zotero has no native mobile app with full-text search. Ridley fills that gap with on-device OCR, annotations, and text reflow.
Search inside your PDFs, not just titles. Full-text indexing finds text across your entire library in milliseconds.
Highlight, underline, and strikethrough with 5 colors. Add comments. Export annotations as Markdown. The Zotero sync path is being hardened.
Scanned PDFs with no text layer? On-device text recognition extracts text locally on your phone. No cloud, no privacy trade-off.
Academic papers reflow to fit your screen. Adjustable font size turns any PDF into a comfortable read on small displays.
Format citations in APA, IEEE, Chicago, Nature, and 10,000+ styles. Powered by the OokCite API. 30 free lookups per day.
Read in the dark with color-inverted PDFs. Jump between chapters via table of contents. Resume where you left off.
Ridley gives individual researchers and teams managed storage that feels like a normal sign-in flow, not a manual sync setup.
Ridley gives you EU-hosted storage for larger personal libraries without turning setup into an IT project.
Use the Ridley Zotero extension for shared libraries. Sign in once and Ridley loads personal and group storage automatically.
Data stays in European data centers. Encrypted in transit and at rest. No US cloud intermediary.
Each group gets scoped credentials. Members access only their group. Admins control everything from one dashboard.
Sign in once in the Zotero extension. Your personal library and any shared groups appear automatically.
Start with the app, add storage when you need it, and turn on shared-library sync when your team is ready.

Read on Android for free, add managed storage when your library grows, and enable team sync when shared files matter.
Focus: Ridley is one product: a mobile reader, managed storage, and shared-library sync for research teams.
Access: Sign in once through your TurtleTech account and Ridley loads the storage you already have.
Compatibility: Legacy WebDAV remains available as a compatibility path, but the normal setup is the Ridley extension and account flow.
