Alpha Neuron vs Vpin｜網路影片學習輔助工具

Documents turns your iPhone, iPad, or Mac into a simple PDF workbench. Open or scan a PDF, reshape it, then send it on its way — no subscription, no account, no clutter. Work on one document at a time. Give it pages, edit them, and share the result. Your edits are non-destructive within a session, and Undo and Redo let you step back and forth through your changes. FIVE WAYS TO EDIT • Merge — Append other PDFs or images to your document. Reorder, preview, and crop photos of pages before they're added. • Structure — Reorder pages by dragging, remove pages, add blank pages, and rotate individual pages. • Extract — Keep only the pages you choose and discard the rest. • Compress — Shrink file size with Low, Medium, or High compression, and see exactly how much space you saved. • Resize — Reshape pages to A4, Letter, Legal, or a custom size, in portrait or landscape. SCAN PAPER Use your device camera and Apple's built-in document scanner to capture pages straight into your document. EXPORT YOUR WAY Optionally password-protect your PDF, then Share it via AirDrop, Messages, and Mail — or Save to Files. PRIVATE BY DESIGN Nothing leaves your device unless you send it. No cloud sync, no accounts. Your files stay on your device while you work. ONE-TIME PURCHASE Try every feature free for 30 days. When you're ready, a single purchase unlocks the app for good — tied to your Apple ID, so it restores automatically across all your devices. No subscriptions, ever.
