Use full-text search to find even the most deeply nested document. PLAN AND ACT Turn books into project lists and documents into tasks. Assign due dates and alerts, create nested projects, and track progress naturally — right where your work lives.

Use wiki-style links, backlinks, contexts, and smart books to keep everything connected and within reach. When you rename or move documents, links stay intact. A PLACE YOU CAN RELY ON Sync your documents between iPhone, iPad, Mac, and PC. Work on documents stored in other apps, compile selections into PDFs or eBooks, scan documents and extract text using OCR, and trust that your data stays accessible — now and in the future. With time, Notebooks often becomes the one place users rely on to keep everything that matters close at hand. WHAT USERS SAY “Notebooks is a wonderful app — sophisticated in an unassuming way. I feel more productive without spending time managing the app itself.” “You are GTD in every way that makes it efficient — and makes me efficient.”
