機能比較
These two tools overlap in only one area: PDF work. Below, we compare 10 features, including the ones only one tool offers.
| 特徴 | テナーシェア | ニトロ PDF |
|---|---|---|
| 開始価格 | 月額4.49ドル | 1ユーザーあたり月額15ドル |
| 無料オプション | ✅ Free scan & preview | ❌ 14日間限定の無料トライアル |

1. PDF Editing
テナーシェア： PDNob is Tenorshare’s AI PDF editor. It lets you edit text, mark up pages, and summarize long files with AI. The only downside is depth, since it’s one app inside a much bigger suite.
Nitro PDF: Editing is Nitro’s core job. You click into any text box and change words, fonts, or layout directly. Nitro Pro is a powerful PDF editor for contracts, reports, and forms.
2. OCR and Image to Text
テナーシェア： The Image to Text tool pulls words out of screenshots and photos. It’s quick for grabbing text from a receipt or a slide.
Nitro PDF: Nitro’s OCR turns whole scanned documents into searchable, editable PDFs. It also turns images into PDF files in a few clicks.
3. Word and Excel Conversion
テナーシェア： Tenorshare isn’t built for heavy Office conversions. PDNob and ChatPDF focus on editing and reading PDFs, not round-trip exports.
Nitro PDF: Nitro turns Word files into PDFs and PDFs back into Word. Formatting stays mostly intact, which saves a lot of cleanup time.
Spreadsheets work the same way. You can turn an Excel file into a clean PDF.
Need the numbers back in a spreadsheet? PDF to Excel keeps your columns lined up.
4. Presentations
テナーシェア： AI Slides builds a deck from a topic or a few notes. It suits students and marketers who need slides fast.
Nitro PDF: Nitro doesn’t create slides. It converts PowerPoint files into PDFs for sharing.
It also works in reverse, turning a PDF back into editable slides.
5. Images and Translation
テナーシェア： Image Translator reads text in a picture and translates it into English. It’s useful for menus, signs, and foreign paperwork.
Nitro PDF: Nitro exports PDF pages as images for slides or the web. It doesn’t translate text.
6. eSignatures and Document Security
テナーシェア： Tenorshare has no e-signature tool. Its data security focus is on getting files back, not locking them down.
Nitro PDF: You can sign a contract in seconds without printing it. Files stay protected with encryption and permissions while you edit and sign.
💡 プロのヒント: Use Nitro’s redaction tool instead of black highlight boxes. Redaction removes the hidden text from the file for good.
7. AIライティングツール
テナーシェア： AI Writer drafts short posts and emails. AI Humanizer rewrites stiff AI text so it reads more naturally.
AI Bypass goes further, letting you rework the program’s output so AI検出器 flag it less.
Nitro PDF: Nitro has no AI writing tools in these plans. It sticks to editing, converting, and signing.
⚠️ 警告： AI detection bypass tools can break 学校 or workplace rules. Check your policy before you use them.
8. Data Recovery
テナーシェア： This is where Tenorshare shines. Its data recovery software covers both computer essentials like 4DDiG and phone tools like UltData. Tenorshare offers a free scan first. You can find out if the recovery process works before you pay.
Nitro PDF: Nitro has no recovery features. After data loss, you’ll need a separate tool.
9. System Repair and Device Unlocking
テナーシェア： ReiBoot repairs phones stuck in recovery mode or a boot loop. 4uKey claims to help with an iPhone locked by a passcode, Apple ID, or MDM profile. It also claims iCloud activation lock removal, but results vary by device.
Tenorshare also sells a location changer that sets your phone’s GPS position for apps.
Nitro PDF: Nitro doesn’t repair devices. It’s purely document software.
⚠️ 警告： Only unlock devices you own. Activation lock exists to stop theft. Bypassing it on someone else’s phone can be illegal.
10. 価格設定とコスト
| プラン | テナーシェア | ニトロ PDF |
|---|---|---|
| エントリ | AI Writer $4.49/month, ChatPDF $4.49/month | Standard $15/user/month |
| 中級クラス | AI Bypass $9.99/month, AI Slides $9.99/month | Plus: Custom |
| トップ | PDNob $14.99/month | Classic $270 one-time |
| 無料オプション | Free scan & preview | 14日間無料トライアル |
テナーシェア： Each app is cheap, and you only pay for what you need. The catch is that every tool bills separately, so buying four adds up fast.
Nitro PDF: Nitro costs more each month but bundles editing, OCR, conversion, and signing. It’s often 30% to 60% cheaper than Adobe Acrobat, depending on the plan.
