Lectra Notes · Notebooks
Jupyter notebooks that run on your iPad. Offline.
Real .ipynb files, a real Python kernel, and inline charts — in the same library as your readings and handwritten notes. No cloud kernel, no account, no connection required.

Notebook features in Lectra Notes
Real .ipynb files
Notebooks are genuine Jupyter documents. Import one from class, work it, and it round-trips — cells, outputs, and metadata preserved.
A live kernel, on the iPad
Code cells run real CPython on the device with state that persists across cells — variables defined in one cell are there in the next.
Charts where you made them
numpy, pandas, matplotlib, and Pillow ship built in. Plots render inline in the notebook, computed entirely on the iPad.
More packages when you need them
Install many pure-Python packages from PyPI in a cell; installs are kept locally so the notebook still runs next time, offline.
No cloud kernel, no account
Nothing executes on a server. Airplane mode in lecture, a basement lab, a flight home — the notebook neither knows nor cares.
Beside your handwriting
Notebooks live in the same library as your PDFs and Pencil notes — the reading, the derivation, and the computation stay together.
How it works
Import, run, hand back.
Import an .ipynb through the Files app or the share sheet — or start a fresh notebook — then run cells against on-device Python. When it's done, export a standard notebook that opens in Jupyter anywhere. For scripts, a shell, and version control, see the coding workspace; for handwritten work on paper styles, that's what the rest of Lectra Notes is for.
Questions
Notebooks on iPad, answered.
Can I run Jupyter notebooks on an iPad?
Yes. Lectra Notes opens and runs real .ipynb notebooks with an on-device Python kernel — markdown and code cells, persistent state, and inline plots, with no cloud kernel behind it.
Does it need an internet connection?
No. Python runs entirely on the iPad, so notebooks execute offline. You only need a connection the moment you install a new package from PyPI — after that, the install is kept locally.
Which packages are included?
numpy, pandas, matplotlib, and Pillow ship with the app, and many pure-Python packages can be installed from PyPI inside a notebook cell.
Is it real Python?
Yes — real CPython running on the device, not a subset or a remote interpreter. The same code that runs in class runs in Lectra Notes.
Are notebooks a paid feature?
No. Lectra Notes is free with no tiers or subscriptions — notebooks, the terminal, Git, and the code editor are all part of the free app.
