Features
A tablet notebook with a real file system.
Penink is more than a simple note-taking app. It is a digital notebook and personal workspace — built for handwriting, documents, and folders that nest.
Handwriting
Write naturally with Apple Pencil or a compatible tablet stylus. Fountain, ballpoint, pencil, and brush — on paper that feels like paper.

File organization
Create folders inside folders. Keep notebooks, PDFs, and files together the way you already think about them — like Finder or File Explorer.

PDF annotation
Read, highlight, and write on PDFs next to your notebooks. Textbooks, assignments, and research live in the same workspace.

Search
Search notebooks, handwriting, PDFs, and files. Penink helps you get back to the sentence, lecture, or document you need.

Study tools
Create flashcards and study questions from the notes you already wrote — useful before exams, not instead of writing.

Smart tools
Summarize, explain, and find related information in the notes and documents you already have. Smart tools sit beside handwriting — they don’t replace it.
