Lectra Notes vs Pencora

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.

Pencora is paper that thinks: a fast, private notebook for serious study that keeps up with your hand and helps you find, build, and protect what you learn. Everything is free. No subscription. No ads. No account. FIND ANYTHING YOU WROTE Your handwriting becomes searchable as you write—on your iPad, without uploading your notes. Search across every notebook, jump straight to the highlighted word, and find text inside added photos too. Pencora supports English, Russian, Ukrainian, Spanish, French, German, Italian, and Portuguese, and handles messy handwriting, close matches, and typos. WRITE WITHOUT THE LAG A custom Metal engine draws each stroke immediately with pressure, tilt, hover, and Apple Pencil Pro squeeze. Even large notebooks stay smooth. Prefer a finger? You can write with that too. MOVE IN WITHOUT STARTING OVER Export your notebooks from Goodnotes, Notability, or any other note app as PDF. Pencora detects the paper ruling, keeps pages in order, and converts handwriting stored as vector ink into editable strokes instead of locking it inside a picture. Large documents open quickly and keep converting in the background. TYPE IT. GET YOUR HANDWRITING. Write a set of sample words once—or pick a ready-made hand—then type or paste Markdown, lists, and LaTeX formulas. The on-device handwriting model places them on the page as real, erasable strokes in your style, following the ruling of the paper. Available in English and Russian. Nothing is uploaded for generation. MATH THAT STAYS LIVE Add interactive graph planes directly to a page. Plot functions, implicit curves, points, and tables; import CSV; or draw a table by hand and let Pencora read it. Ink written on the plane stays attached to its coordinates. Build exact geometry beside your proof: points, segments, lines, circles, polygons, curves, midpoints, perpendicular and angle bisectors, parallels, tangents, intersections, reflections, and triangle centers. Drag a point and every dependent construction moves with it. Measure in real millimeters and label points in your own handwriting. THE TOOLS A REAL NOTEBOOK NEEDS • Lined, grid, dotted, or PDF paper • Shape snapping for lines, circles, and polygons • Highlighter, study tape, and scribble-to-erase • A lasso that moves, scales, rotates, and changes stroke width • A zoom-write strip for small, neat writing • Calligraphy nibs and an eyedropper • Markdown text boxes and live formulas • True-vector PDF export that stays crisp at any zoom • Folders, tags, and tabs • An infinite board with a minimap for every notebook NEVER LOSE A PAGE Connect Google Drive for automatic daily backups to your own account. Pencora keeps the five newest copies and can restore your library on a new iPad. It uses Google's limited-access permission, so it sees only its own backup files—not the rest of your Drive. You can also export your entire library into one backup file whenever you want. YOUR NOTEBOOKS ON IPHONE Connect the same Google Drive on your iPhone to read the notebooks from your iPad's latest backup, with folders and names intact. You can also open any .handynotes notebook someone sends you. Editing stays on iPad; on iPhone, notebooks are read-only. PRIVATE BY DESIGN Recognition, search, and handwriting generation run on your device. Pencora has no accounts, ads, or tracking, and never sells your data. Anonymous usage statistics can be turned off in Profile, and sharing handwriting samples for research is strictly opt-in. Your notes are not the product. Built by one developer who uses handwritten notes every day. Your feedback helps decide what gets built next.
