Grammarlyとは何ですか？
Grammarly is a writing assistant that checks spelling and grammar as you type.

It flags a misspelled word, then explains why the fix is correct.
Artificial intelligence reads context to separate commonly confused words.
It runs inside Google Docs, Microsoft Word, and Slack.
A browser extension covers everything else you write online.
This walkthrough shows the editor in action.
Runner Up: Grammarly
Catch errors in every app you already use. The free version has no word cap on grammar checks.
Grammarlyの価格
Grammarly offers three tiers. The paid tier is widely known as Grammarly Premium.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料 | 0米ドル | Spelling and grammar basics |
| プロ | 12米ドル | Tone, rewrites, plagiarism detection |

無料トライアル: There is no timed trial. The free version stays free with unlimited grammar checks.
返金保証: Refund requests go through support. You can cancel a premium subscription from your account page.
📌 注記： The plan is listed as Pro in our data. Grammarly Premium is the same paid tier under its older name.
⚠️ 警告： Plagiarism detection and full-sentence rewrites sit behind the paid tier. The free plan will not scan your own work against the web.
Grammarlyの主なメリット
Here is where Grammarly earns its place:
- Grammar checker: Catches subject-verb agreement and misplaced modifiers, not just typos.
- Tone suggestions: Analyses your writing style so the message matches your audience.
- Clarity edits: Flags wordy phrases and offers shorter alternatives in a few clicks.
- アクティブ 声 prompts: Suggests swapping passive voice for stronger sentences.
- Teaching feedback: Explains each fix, so you learn from repeat mistakes.
- Grammarly Keyboard: Brings checks to your phone in English, Spanish, French, German, Portuguese, and Italian.
- Document editor: Cloud storage, personal writing statistics, and plagiarism detection in one place.

機能比較
These two products barely share a feature list. Both are modern tools, yet only one doubles as a review tool for papers. We lined up eleven areas so you can see exactly where each does the hard work, and where it leaves you stranded.
| 特徴 | サイスペース | 文法 |
|---|---|---|
| Starting paid price | $8 | $12 |
| 無料プラン | ✅ | ✅ |
| Semantic search across papers | ✅ | ❌ |
| PDFでチャット | ✅ | ❌ |
| 引用ジェネレーター | ✅ | ✅ |

| 盗作チェッカー | ✅（ターニチン） | ✅（有料） |
| AI検出器 | ✅ | ✅ |
| ブラウザ拡張機能 | ✅ | ✅ |
| 最適な用途 | Literature review, thesis work | Everyday editing, polished writing |
1. Reading and Understanding Papers
サイスペース: Chat With PDF answers questions using specific sections of the document, with citations attached. Highlight confusing math or tables and you get simple explanations back.
文法: The free essay and paper checker reviews text you paste in. It has no idea what the paper argues, so it cannot resolve your doubts about the content.
2. 文献レビュー
サイスペース: The literature review workspace lets teams analyse papers together and share AI summaries. Search results come from a phrase or a research question, not keywords.
文法: A citation finder helps you trace a source you already know about. There is no way to discover related papers from scratch.
⚠️ 警告： Using SciSpace for a systematic literature review may not be advisable. Reproducibility of the search is hard to prove to a review panel.
3. AIライティング
サイスペース: The AI writer drafts manuscript sections from papers already in your collection. A unified agent can search databases and draft in one pass.
文法: Generative AI drafts and rewrites text from a short prompt. It writes fluently but pulls nothing from scientific literature.
4. 言い換え
サイスペース: The paraphraser adjusts both tone and length of the passage you feed it. Useful when a quoted method section needs rewording for your own work.
文法: Full-sentence rewrites sit inside the premium features. The rewrite protects your vocabulary and 声 better than most rivals.
5. 引用ジェネレーター
サイスペース: Produces in-text and reference citations in over 9,000 styles. Every Copilot answer also carries its own citations back to the source.
文法: Formats a reference once you supply the details. It cannot verify that the study you cited says what you claim.
6. Grammar, Spelling and Proofreading
サイスペース: Basic spelling and grammar cleanup only. Serious proofreading still needs a second tool.
文法: The grammar checker catches complex errors that a spell-checker misses. It also explains the fix, so the same sentence problem stops repeating.
The dedicated proofreading view handles longer documents.
7. Tone and Writing Style
サイスペース: Tone control is limited to the paraphraser. There is no live feedback on style as you type.
文法: Tone suggestions read the context and tell you when a message lands wrong. Setting a goal helps you hit the right tone for a supervisor or a client.
✅ Where this helps: G2 reviews highlight tone feedback as the reason writers feel confident sending an email without a second read.
8. Plagiarism and AI Detection
サイスペース: A Turnitin integration checks text similarity before thesis submissions. The built-in AI detector flags passages that may raise potential academic misconduct questions.
文法: The plagiarism checker scans written content against billions of web pages on the paid plan. An AI detector and an AI humanizer sit alongside it.
Detection and rewriting live in separate panels.
The humanizer smooths AI-flagged passages.
⚠️ 警告： No AI detector is reliable enough to clear a paper for the publishing process. Treat every score as a hint, not a verdict.
9. Research Agents and Data Extraction
サイスペース: The agent gallery runs multi-step jobs across databases using several AI models. The data extractor pulls chosen data points from many papers into customizable tables.
Extraction runs on PDFs you upload yourself. For example, a methods table drawn from six studies lands in one grid.
Topic Finder narrows a broad area into a workable research question.
文法: No research agents and no extraction. It reads the document in front of it and nothing beyond that.
10. Everyday Writing Extras
サイスペース: A Chrome extension surfaces explanations while you browse a journal page. Bookmarks save an article to your collection for later analysis.
文法: A free word counter and reusable snippets cover the small daily stuff. The Grammarly mobile app and keyboard extend the same checks to your phone in multiple languages.
Snippets save phrases you retype constantly.
✅ Worth knowing: Release notes for the software list steady bug fixes and small feature updates rather than yearly rewrites.
11. 価格設定とコスト
Let’s put the plans side by side.
| ティア | サイスペース | 文法 |
|---|---|---|
| 無料 | 基本料金：0ドル | Free: $0 USD |
| 入場料支払い済み | Teams: $8 | Pro: $12 USD |
| 中程度の給与水準 | プレミアム：12ドル | — |
| 最高級 | Advanced: $70 | 法人向け：営業担当までお問い合わせください |
サイスペース: Premium at $12 buys unlimited chats and unlimited citation generations. Advanced at $70 only makes sense for heavy extraction across a large collection.
文法: Pro at $12 unlocks tone, rewrites, and plagiarism detection. Enterprise pricing is quoted per team, so budget an extra call with sales.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |

私たちのレビューで取り上げられなかったこと
We focused on individual researchers and small teams. We did not test the SciSpace virtual file system layer that unifies data across dispersed コンピューティング data centres, and we did not evaluate Grammarly Enterprise deployment or developer API access. Our notes reflect the July 2026 versions of both products. If you manage an institutional rollout, your priorities will differ from ours.

🏆 優勝：SCISPACE
SciSpaceは7部門中4部門で受賞した。
最適な用途: Literature review, thesis submissions, and any project where citations must hold up
SciSpace and Grammarly are two different products that share a search box. SciSpace is a research assistant that reads papers for you. Grammarly is an editor that reads your sentences.
Grammarly is excellent at what it does. If your written work is email, reports, or blog posts, it is the more helpful tool by a wide margin.
But if you hope to publish, the bottleneck is rarely commas. It is finding related papers, reading them, and citing them correctly. SciSpace attacks that part of the job, which is why it takes our pick.
SciSpace is the more versatile tool for research work, but neither promises mistake free output. Great writing still comes from the person at the keyboard.
Plenty of researchers run both. At $8 and $12, that is a reasonable way to achieve a clean draft backed by real sources.
