## What is Libellus One?

Bring your reading and your thinking together. Libellus One combines a local document library, PDF search and Workpapers on iPad and iPhone.

BUILD YOUR LIBRARY
Import files or whole folders with subfolders. Connect to iCloud, WebDAV or a web portal, or sign in to Google Drive to browse and download selected files and folders. Keep local copies organized and available offline. Give a document a Custom Name while retaining its original file name.

FIND NAMES AND PASSAGES
Search document names, custom names and readable PDF text. Search your whole Library or selected folders. Open a matching passage and continue searching inside the PDF.

READ AND TAKE NOTES
Use one compact toolbar across PDFs and Workpapers. Write with Apple Pencil or enable finger drawing, highlight, erase and add straight or serrated underlines. Place editable text boxes with font, size and color controls. Move or resize your text and return to navigation with the Hand tool. Edits save automatically, with session Undo and Redo.

KEEP THE SOURCE
Take a Note turns a selected passage into a source-linked Workpaper card. Tap its reference to return to the original. Readable text in PDF, TXT, DOCX and XLSX is supported.

MAKE ROOM TO THINK
Use Double Screen for two documents or a local video beside your reading. Arrange Workpapers beside or below documents. Adjust dividers, zoom, and move your toolbar to any corner. Navigate with thumbnails, outlines and bookmarks.

CHOOSE YOUR WORKSPACE
Place navigation on the left, right or bottom, with icons or labels. Keep navigation and document tabs visible or let them appear automatically when needed. Choose horizontal or vertical page turning and continuous or page-by-page reading. Reading mode adds a display-only warm paper tint. An English User Guide is included offline.

Cloud connections require your own authorized account and internet access. Google Drive downloads are local copies, not automatic remote synchronization; provider access rules apply. Downloaded documents and Workpapers remain available on your device. PDF text search requires readable text; scanned or protected files may not be searchable. Apple Pencil requires a compatible iPad.
