Lectra Notes
Notes, PDFs & Python
Free · Designed for iPad. Not verified for macOS.
Lectra is a workspace for the documents you think on: lecture slides, problem sets, papers, and textbooks, marked up by hand and kept in one library that works without a signal.
READ AND MARK UP
Open any PDF and work it over with Apple Pencil. A pressure-responsive pen, highlighter, and eraser in a calm, distraction-free editor keep your ink sharp at any zoom. Select the document's own text with a finger. On Apple Pencil Pro, squeeze to switch tools.
MADE FOR IPHONE DUO
Folded, Lectra fits the outer screen. Open it, and your page spreads across the full display, with every control kept clear of the camera and status bar. On iPad, keep two documents side by side.
RECORD THE LECTURE BESIDE YOUR NOTES
Start recording from a control that floats above the whole app, then keep writing. Tap a handwritten stroke to hear what was being said as the pen moved. Drag the playhead and watch the page fill back in, stroke by stroke. Transcription runs on your iPad, and an hour of lecture takes about 15 MB.
NOTEBOOKS AND PAPER
Start from a blank page when the thinking hasn't found a document yet. Choose blank, lined, grid, dotted, or Cornell paper for each new page, then export your pages as PDFs.
SCAN ANYTHING
Bring paper into the record. Scan pages with the camera and mark them up like any other PDF.
ASK YOUR DOCUMENTS
Ask a question about what you're reading and get an answer that cites the page it came from. Summarize a document to get to the point faster. These features run on your iPad, are off until you turn them on, and never use your notes or documents to train a model.
WHEN READING TURNS INTO WORK
Run Python where you already work: notebooks with charts, a real shell, Git, and a code editor, all on your iPad and all offline. The document and the work on it stay in the same place.
YOUR MAC, TOO
Lectra for Mac is a free download at canvascope.org/mac. It brings the whole app to your desktop, puts your Mac on your iPad as a remote desktop, sends documents straight between iPad and Mac, and shares one clipboard. The Remote Desktop assistant can open a website, search, or launch an app on your Mac in one step, and asks before it acts unless you turn on Auto-run.
A LIBRARY THAT KEEPS UP
Everything in one place, available offline, and backed up when you sign in. Your documents are yours: export them anytime, in formats that open anywhere.
PRIVATE BY DESIGN
No ads and no tracking.
Lectra is free to use.
