Tertiary NotePad
Read full descriptionHide full description
NotePad is a clean, native iPad note-taking app built for Apple Pencil. It feels like a paper notebook with the power of digital ink. - Handwriting with pressure and tilt, low latency, and palm rejection - the Pencil draws while a finger scrolls and two fingers zoom. - GoodNotes-style tool bar: pen, highlighter, erasers, color dropdown and widths. - White paper or blackboard templates, applied across the whole notebook. - Shapes and flowcharts (process, decision, start/end, connectors) with editable vector overlays; connectors re-route when you move a node. - Type directly into sticky notes and flowchart nodes (multi-line, with background colors). - Lasso to move, delete or copy multiple strokes; recolor and edit shapes. - Import PDFs and annotate them; export pages or whole notebooks to PDF/PNG/JPG. - Organize with nested notebooks and tags, and search inside your handwriting. - Record voice memos per notebook. - Everything syncs across your devices with iCloud.

AI that starts with your handwriting ⢠Search the web from questions written by hand and get organized answers. ⢠Solve equations and view step-by-step solutions. ⢠Organize handwritten content into tables. ⢠Create function graphs directly from your notes. ⢠Use your notes and imported materials as context for AI search. Tools that work on the page ⢠View search results and browse the web without leaving your note. ⢠Use calculators, math tools, tables, and graphs alongside your handwriting. ⢠Add maps, calendars, to-dos, timers, and memos to the page. ⢠Pass results between connected tools to continue your work. Bring the materials you already use ⢠Import, read, and annotate PDFs. ⢠Import PowerPoint and Word documents. ⢠Add images and documents to your notes. ⢠Combine handwriting, sketches, materials, and AI results on one page. ⢠Search handwriting and content across your notes.
