PDF Reader & Tools

Features
Read full description

PDFKit is the privacy-first PDF reader and toolbox that does everything on your device — no uploads, no accounts, no waiting in line. Open any PDF and read it like a book, with paginated turn animations, sepia/dark backgrounds, font-size and line-spacing controls, bookmarks, and highlights that sync across reading sessions. Or stay in classic document mode for forms, contracts, and reports. Then jump straight into the toolbox: merge multiple PDFs, split a single document by page range, compress a giant scan to email size, convert images to PDF (and PDF pages back to images), rotate, reorder pages, add a password, watermark a draft, or stamp page numbers. Every operation runs locally — your files never leave your device. BUILT FOR READING • Three reader modes: Document, Book (paginated), Reflow (resizable text) • Five backgrounds: White, Sepia, Gray, Dark, AMOLED Black • Bookmarks and highlights, with one-tap export • Auto-resume where you left off, even across app restarts FULL OFFLINE TOOLBOX • Merge multiple PDFs into one • Split by page range or every N pages • Compress with quality presets (low / medium / high) • Convert images (JPG/PNG/HEIC) to PDF • Convert PDF pages to images • Rotate, reorder, delete pages • Password-protect a PDF • Add watermark or page numbers PRIVACY FIRST • 100% on-device processing — files NEVER uploaded • No account required • No data collection or tracking • Works fully offline LIBRARY YOU'LL ACTUALLY USE • Grid and list views • Filter by recents, favorites, or completed • Sort by name, date, size, or last opened • Search across imported documents • Custom collections for organizing If you've been frustrated by web-based tools that limit free uploads, slow conversion queues, and unclear data policies, PDFKit is the tool you've been waiting for. Read your PDFs, fix your PDFs, and keep them entirely yours. Download PDFKit and own your PDF workflow.

Read full description

A drop zone for the markdown documents your AI assistant writes. MD Inbox watches a folder in iCloud Drive on your Mac. When Claude, ChatGPT, Cursor, or any other AI tool saves a markdown file there — a plan, spec, code review, design doc, meeting notes — it appears on your iPhone within seconds. Read it on the go, pin the ones that matter, delete the rest. HOW IT WORKS 1. Pick any folder in iCloud Drive as your inbox. 2. Copy a short prompt into your AI agent's system prompt. 3. From now on, finished documents your agent produces show up here. FEATURES • Live iCloud sync — files appear seconds after your agent saves them • Date-grouped sidebar: Pinned, Today, Yesterday, This Week, This Month, Older • Swipe to delete, tap to pin, multi-select for batch cleanup • Auto-delete after a configurable threshold to keep the inbox tidy • Pinned and read state sync between devices via iCloud • Native markdown rendering with code blocks, tables, and images • Share extension — send markdown from any app THREE BUILT-IN AGENT PRESETS • Plans & Specs — agent auto-saves substantial deliverables • On-Demand — agent saves only when you ask • Quick Captures — short, timestamped notes No account, no server — your files live in your own iCloud Drive.
