Lucid Note
Handwrite & Annotate PDF Notes
Free · Designed for iPad. Not verified for macOS.
Lucid Note is a simple note-taking app that lets you annotate any PDF with Apple Pencil.
■ Write on Password-Protected PDFs
Open and annotate PDFs protected with edit restrictions — company documents, study materials, and more — without any extra steps. Files that other apps can't open work seamlessly in Lucid Note.
■ Intuitive Writing
• Handwriting on PDFs — Write notes and draw diagrams directly on any PDF using Apple Pencil. Adjust pen width and color freely with the tool palette.
• Smooth zoom — Pinch to zoom in and out, two-finger scroll to pan. Write comfortably even in the finest details.
• Easy page navigation — Tap the left or right edge of the screen to flip pages.
• Stamps — Press date frames, daily schedule frames, and task checkbox frames as stamps onto your pages. Drag with a finger to reposition them anywhere.
■ Note and Page Management
• Create new notes — Choose a background style (blank, lined, grid, dot grid, legal pad) and paper size (A4 / A5 / US Letter) to start a fresh notebook.
• Add, delete, and reorder pages — Freely add pages to a note, or rearrange them by dragging in the thumbnail grid.
• Tag-based file management — Create custom tags to organize your files. Filter by tag instantly from the sidebar.
• Simple file management — Rename or delete files right from the list.
■ Sharing and Productivity
• Export annotated PDFs — Export a PDF with your handwriting, backgrounds, and stamps all merged in, ready to share.
• Handwriting recognition and search (experimental) — Using Apple's handwriting recognition technology, your notes are converted to text so you can search by keyword. Accuracy may vary by handwriting style and language.
• iCloud backup — Your imported PDFs and annotations are backed up automatically.
Open a PDF and start writing — it's that simple.
