UnivNote: Lag-Free PDF Notes

UnivNote — Smooth PDF Note App

UnivNote focuses on the essentials of reading, writing, and organizing PDFs instead of adding AI clutter.

Write directly on textbooks, lecture slides, papers, and books with iPad and Apple Pencil. You can also open and manage your notes on iPhone and Mac. Pen, highlighter, lasso, page management, recording, and search are designed to feel light and immediate.

UnivNote is continuously optimized for screen recording, Split View, Stage Manager, and multi-window use. Smooth handwriting, low heat, and long battery life are core priorities.

▶ What Makes UnivNote Different

· A focused writing tool without AI clutter While many note apps emphasize AI summaries, automatic organization, and automatic search, UnivNote focuses on the handwriting experience itself. Responsive pen input, fast lasso editing, simple copy and paste, and a stable PDF reader come first.

· Fast writing with lower heat Input stays responsive even when a page contains many strokes. UnivNote is continuously tuned to reduce heat and battery drain in heavier workflows such as Split View, multiple UnivNote windows, and writing while recording the screen.

· Built for lectures and screen recording Use the laser pointer, reading mode, gesture shortcuts, audio recording, and synced playback. Whether you are taking class notes or recording an iPad lecture video, UnivNote helps keep controls out of the way and interactions quick.

· Lasso selection with instant actions Select handwriting with the lasso and Copy, Cut, Duplicate, and Delete actions appear immediately. No long-press menu required.

· Extend PDF margins on all four sides When a textbook or worksheet has too little margin, extend the top, bottom, left, or right side and write freely in the added space.

· Audio recording synced with handwriting Record lectures or meetings while writing. Later, tap a note to jump back to that moment in the audio.

· Word-aware highlighting on PDF text Long-press PDF text with the highlighter and highlights align to words precisely. Regular highlighter, masking highlighter, and opacity control help with review and memorization.
