Read full descriptionHide full description
Fix a typo on an invoice. Change a date on a contract. No computer, no software, no account. EDIT THE TEXT OF A PDF Tap a line, rewrite it. The original font, size and colour are kept — nothing else on the page moves. Almost no app can do this on a phone. SIGN AND ANNOTATE Your signature drawn with a finger, your stamps, text, drawings. Save your signatures and stamps once and they are waiting for you on the next document. SCAN The camera straightens the page by itself. Several pages in a row, colour, grey or black-and-white filters, and you can adjust the edges by hand. COMPRESS A PDF, some photos or a video, in three plain choices. The final size is written on every choice before you decide, and when a file cannot be made smaller, the app says so instead of making you wait. CONVERT Word to PDF, PDF to images, images to PDF. BLANK PAGE A real Word editor: headings, bold, colours, lists, and templates ready to write in — letter, note, invoice, report. CV AND COVER LETTER WRITTEN BY AI Answer a few questions and the AI writes. Professional templates, export to PDF or Word. NO SUBSCRIPTION The PDF tools, scanning, compression and signing are free and unlimited. The rest runs on credits: 1 credit = 1 document. You pay once for a document, then you export it as many times as you like, even after correcting it again. Credits never expire. NO ACCOUNT No sign-up. The PDF tools, scanning and compression work on your phone. Only the CV and the cover letter go through our server, for as long as it takes to write them. BookyAI speaks 17 languages.

Libreto is a full drawing studio, digital notebook, planner, and PDF editor for iPad and iPhone Duo, and a streamlined PDF editor and notes app for iPhone. Private by design, with on-device AI included, and one fair price. MADE FOR IPHONE DUO Open it up and notebooks, planners, and PDFs lie open as two pages across the fold. Folders show a list beside a preview, and planner links open on the facing page. 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. DRAW & SKETCH (iPad and iPhone Duo) A full drawing canvas with pressure brushes, layers, blend modes, and a saved color palette. In landscape, Sketch Studio docks your reference image, layers, and colors beside the canvas. Real symmetry: vertical, horizontal, both axes, or radial. Pro adjustments and filters: hue, curves, gradient map, blurs, halftone, chromatic aberration, and more. Import photos to trace or paint over, export as PNG or PDF. NOTEBOOKS FOR APPLE PENCIL (iPad and iPhone Duo) Lined, dot grid, grid, graph, Cornell, and to-do paper, or import any photo as your own. In landscape, notebooks and PDFs open as a two-page spread. Ink thickens on slow strokes and tapers at the ends, like a real nib. 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. Apple Pencil works on iPad and iPhone Duo; no Pencil, or another iPhone? Write with a finger. TEXT DOCUMENTS Prefer to type? Text Documents with markdown, headings, and checklists you can tick in the preview. PLANNERS, YOUR WAY (iPad and iPhone Duo) 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, Light or Dark theme. Covers you can recolor, replace with a photo, or make with Image Playground. PDF TOOLS (iPad and iPhone) Highlights, ink, shapes, stickers, and signatures, with undo and redo for every mark. 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. Prefer not to subscribe? Buy Libreto once for $59.99 and keep every feature, including future updates, forever. Terms of Use (Apple standard EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
