Pick a document style, compile to PDF in the app, and share the PDF or the .tex file wherever it needs to go.

Any pen, any finger
Draw with Apple Pencil, a stylus or your finger. Turn on Pencil-only mode for palm rejection.
Paper you choose
Blank, ruled, grid or dotted, in white, cream or mist.
One document per notebook
Every page becomes LaTeX and joins one document. Macros are collected. Proofs can run across pages.
Three document styles
Default, tagged or boxed theorems. Compile to PDF inside the app.
Bring paper in
Scan pages with the camera, import PDFs and photos, then write on top.
Works offline
Write anywhere. Pages convert when you are back online.
Share how you like
Copy the LaTeX, share the .tex file or the PDF, or open the project in your editor of choice.
English and Spanish
The app speaks both, and your notes can be in any language LaTeX can typeset.
