About this app

Handwriting notes, PDF annotation, and an AI study assistant — built for Android tablets and styluses. Highlighted at Google I/O 2025.

Orion Notes is the note-taking app for students, teachers, and professionals who think with a pen: take handwritten notes, mark up lecture slides and textbooks, record the lecture, then let AI turn it all into summaries, quizzes, and graded practice.

🖊️ Handwriting That Feels Like Paper
Ultra-low latency ink with pressure sensitivity, tuned for S Pen and other active styluses. Fountain pen, ballpoint, pencil, highlighter, calligraphy pen, tape, laser, and 22 auto-recognized shapes. Ruler, layers, and 20 favorite pen presets.

🔍 Search Your Handwriting
Find any word in your handwritten notes, PDFs, text boxes, and tables. Recognition runs on your device — free, private, no upload.

📄 Import & Annotate PDFs, Word & PowerPoint
Import PDFs, Word, and PowerPoint files, images, or scan paper documents with your camera. Highlight, underline, strike through, add notes, and draw right on the page. Add pages from other PDFs, rotate, reorder, and split into new notebooks. Tap any word for an instant dictionary, or translate selected text in 30+ languages — on device.

🎙️ Record Lectures, Synced to Your Notes
Record while you write. Tap any handwriting to jump to that moment in the recording. Adjust playback speed, skip 15 seconds, or loop a segment for review.

🧠 Organize Your Way
Notebooks, nested folders with color and photo covers, labels, favorites, and pinning. Link pages with hyperlinks, connect two notebooks with bidirectional links, and build study guides or a personal knowledge base. Add editable tables for comparing topics or collecting mistakes. Write on classic paper sizes or an infinite canvas.

📐 Templates & Paper
Cornell notes, vocabulary books, mistake collections, memory-curve review, daily/weekly/monthly planners, meeting notes, music sheets, and more. Save your own templates, import custom fonts, and choose from 50+ covers and sticker packs.

⏱️ Stay Focused
A built-in countdown, stopwatch, and Pomodoro timer on the editing page — for timed practice and revision sessions.

Ratings and reviews

New update made the entire app a laggy blurry mess that is borderline unusable and made some really clunky UI changes compared to the previous version. Extremely embarrassing to release an update like this without fixing it immediately. Don't even bother emailing the support email either because you will not get a response.

Most recent update moved the UI around and it also isn't as stable as it used to be.

I'm very stressed because my notes have disappeared. I paid for this, and now I have to worry that my notes will randomly stop working and show a black screen. Edit: I recently decided to use this again and my premium membership is now gone??? I emailed them and got no response
