Libreto is a full drawing studio, digital notebook, planner, and PDF editor for iPad, and a streamlined PDF editor and notes app for iPhone. Private by design, with on-device AI included, and one fair price. LEARN IT IN MINUTES A 2-minute tour on first launch, then Help & Tutorials: step-by-step guides for every part of the app, each with a Try it button that takes you straight there. LIBRETO INTELLIGENCE, ON YOUR DEVICE Ask questions about any PDF or notebook and get answers with tappable page citations; each conversation is saved for next time. Summarize a document, a page range, or a selection. Turn any document into flashcards and quizzes with spaced-repetition review, or import a deck from Anki or CSV. Record a lecture, then transcribe and summarize it on-device, and tap any line to jump the audio to that moment. Have any PDF or note read aloud, page by page. Search inside every PDF, note, and transcript in your library. All of it runs with Apple Intelligence, right on your device: nothing uploaded, nothing metered, no AI credits. Prefer no AI? One switch hides every AI button. LIBRETO EVERYWHERE Send a PDF, photo, or text file from Files, Mail, or Safari straight into your library, or drag it in from another app on iPad. Start a Quick Note from the + menu, the app icon, Siri, Shortcuts, or ⌘N. Your documents show up in Spotlight. Keyboard shortcuts for undo, find, page turns, zoom, and export. DRAW & SKETCH (iPad) A full drawing canvas with pressure brushes, layers, blend modes, and a saved color palette. Real symmetry: vertical, horizontal, both axes, or radial. Smudge actual pixels at full resolution. Pro adjustments and filters: hue, curves, gradient map, blurs, halftone, chromatic aberration, and more. Pinch to zoom, add text, import photos to trace or paint over, export as PNG or PDF. Apple Pencil Pro: squeeze for brushes, double-tap to swap brush and eraser. NOTEBOOKS FOR APPLE PENCIL (iPad) Lined, dot grid, grid, graph, Cornell, and to-do paper, or import any photo as your own. Search your handwriting and convert it to text on-device, in 20+ languages, in notebooks and in the ink you write on PDFs. Write large in the Zoom Writing window and let the ink land small and neat. Add stickers, washi tape, photos, and AI art with Image Playground. No Pencil handy? Write with a finger. On iPhone, take handwritten or typed notes; iPhone does not support Apple Pencil. TEXT DOCUMENTS Prefer to type? Text Documents with markdown, headings, and checklists you can tick in the preview. PLANNERS, YOUR WAY (iPad) Six planners: Daily, Weekly, Monthly, Scheduling, Personal, and Pro, with real calendar dates and a tappable table of contents. Add habit, goal, schedule, dashboard, and journal pages. Portrait or landscape, Warm or Dark theme. Elegant cover designs you can recolor, replace with your photo, or generate with Image Playground. PDF TOOLS (iPad and iPhone) Highlights, ink, shapes, stickers, and signatures, with undo and redo for every mark. Apple Pencil Pro squeezes for the tool palette and clicks when a shape snaps. Make scans searchable with on-device OCR. Clean up photographed pages with Scan Enhance. Redact for real: the hidden text is destroyed, not just covered, across a whole document at once. Export as PDF, image, text, Word (RTF), or Markdown. PRIVATE BY DESIGN No ads. No tracking. No third-party AI. Your work stays on your devices, with optional private iCloud sync and App Lock with Face ID. MEMBERSHIP Unlock every premium feature for $19.99/year with a 3-day free trial, or $2.99/month.
