Orion Notes: Handwrite & PDFs

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.
