機能比較
Here’s how PDF Expert and Tenorshare compare across ten key areas. The table gives you the quick view first.
| 特徴 | PDFエキスパート | テナーシェア |
|---|---|---|
| 開始価格 | 週4.99ドル | 月額4.49ドル |
| 無料トライアル | ✅ 7日間 | ✅ 限定 |
| PDF編集 | ✅ | ✅ |
| Annotation Tools | ✅ | ✅ 基本 |
| OCR | ✅ | ✅ |
| AIライティングツール | ❌ | ✅ |
| システム修復 | ❌ | ✅ |
| データ復旧 | ❌ | ✅ |
| Windows & Android | ❌ | ✅ |
| 最適な用途 | Daily PDF work on Apple devices | Repair, recovery, and AI extras |
1. PDF Editing
PDFエキスパート: You can change existing text, fonts, images, and links right on the page. It feels like editing a Word doc. Drag and drop files in to get started.
テナーシェア： The AI PDF Editor and PDNob handle basic PDF editing on your computer. They lean on AI help more than manual control. PDF work is a side line, not the core product.
2. Annotation & Comments
PDFエキスパート: The annotation tools let you highlight text, underline, strike out, and add notes. You can drop in stamps, shapes, and margin comments. Bookmarks help you jump around long reports.
テナーシェア： Markup is possible, but it’s thin next to a dedicated editor. ChatPDF takes a different route. You ask questions and get answers pulled from the file.
3. OCR & Scanning
PDFエキスパート: Optical character recognition turns a scan into editable text with one click. An AI Enhance feature cleans up blurry scans first. Your iPhone camera works as a scanner too.
テナーシェア： Image to Text pulls words out of photos and screenshots. The Image Translator then converts that text into other languages. Both are handy for receipts and signs.
4. Convert PDF Files
PDFエキスパート: Convert PDF files into Word, Excel, PowerPoint, and other formats like plain text or images. You can also compress a file to email friends or clients. Exports keep layouts mostly intact.
テナーシェア： Conversion is handled by separate tools rather than one app. AI Slides turns ideas or text into プレゼンテーション decks. It’s more of a content maker than a converter.
5. Signatures & Forms
PDFエキスパート: Sign contracts with your trackpad, iPhone camera, or Apple Pencil. Your signature syncs to every Apple device. Forms detect blank fields and highlight them for you.
テナーシェア： E-signing isn’t a headline feature. If you sign documents weekly, you’ll want a different app for that task.
6. Page Management
PDFエキスパート: Drag pages to reorder them. You can merge files, extract pages, delete, and rotate pages in a few clicks. For example, pull one chapter out of a 200-page manual.
テナーシェア： Basic page tools come with the PDF apps. They cover simple jobs but lack the drag-and-drop thumbnail view.
7. AIライティングツール
PDFエキスパート: AI is limited to scan cleanup. There’s no AI writer or chatbot built in. That keeps the app simple and fast.
テナーシェア： This is a real edge. You get AI Writer, an AI Humanizer, and AI Bypass for rewriting drafts. Each tool is billed on its own.
⚠️ 警告： Be aware that “bypass” tools can break 学校 or workplace rules. Check your policy before using them on graded or client work.
8. System Repair & Data Recovery
PDFエキスパート: Not offered. It’s a PDF editor and nothing more.
テナーシェア： This is the company’s home turf. ReiBoot fixes boot failures, and 4DDiG handles data loss on PCs and drives. Is your iPhone locked? 4uKey targets screen locks and Apple ID. It also covers iCloud Activation Lock and MDM profile screens.
⚠️ 警告： Unlocking tools should only be used on devices you own. Results with activation lock vary a lot, and online reviews are mixed. There are other ways to try first. Apple’s recovery mode or Apple Support can help you set up a new account.
9. Platforms & Ease of Use
PDFエキスパート: It runs only on macOS, iPadOS, and iOS devices. In return, it uses Apple features well, like Apple Pencil and split view. The home screen is clean and easy to learn.
テナーシェア： It covers Windows, Mac, iOS, and Android devices, including the latest OS versions. The only downside is juggling many apps. Each program has its own installer, license, and layout.
10. 価格設定とコスト
Here are both price lists side by side.
| PDF Expert Plan | 価格 | Tenorshare Tool | 価格 |
|---|---|---|---|
| 週刊 | 週4.99ドル | AIライター | 月額4.49ドル |
| 年間 | 週1.53ドル | チャットPDF | 月額4.49ドル |
| 一生 | $139.99 | AIバイパス | 月額9.99ドル |
| — | — | AIスライド | 月額9.99ドル |
| — | — | PDNob | 月額14.99ドル |
PDFエキスパート: The yearly plan gives you every feature on every Apple device. The $139.99 lifetime deal suits Mac-only users who hate subscriptions. It costs less than Adobe Acrobat, and Acrobat doesn’t offer a no-card trial.
テナーシェア： Single AI tools are cheap at $4.49/month. Costs climb fast if you stack several. Online reviews also say some features are free elsewhere.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| Daily PDF editing | PDFエキスパート | Full editor, fast with big files |
| 最低月額料金 | テナーシェア | Single AI tools at $4.49/month |
