私たちのライター陣は、それぞれの動物と実際に触れ合う時間も設けました。
これらの観察結果は、以下の「チームが気づいたこと」のセクションに記載されています。
By the end, you will know which software fits your content creation process.
Fraseとは何ですか？
Frase is an AI powered research and writing platform for SEO content.
It was built in Boston, Massachusetts, back in 2017.
You give it a target keyword and it studies the search results.
Frase pulls the top 20 Google results for that target search query.
From there it builds content briefs, a content outline, and a list of terms.
Its AI writer then drafts sections so you are never staring at a blank document.
🏆 受賞者：Frase
Frase turns a keyword into a brief in minutes. It reads competitors so you do not have to. Best for anyone chasing organic traffic.
フレーズ価格設定
Here is what Frase costs in 2026. Three plans, no free version.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| スターター | 月額49ドル | 個人ブロガーとフリーランスライター |
| プロ | 月額129ドル | Agencies running a steady seo workflow |
| 規模 | 月額299ドル | Publishers producing content at volume |
価格は2026年7月に確定しました。
無料トライアル: No free trial and no free version. You pay before you start writing.
返金保証: Frase offers a 5-day money-back guarantee instead of a trial.
📌 注記： The built-in AI writer is capped by monthly credits, roughly 10,000 AI characters per month. That works out to about 1,500 to 2,000 words. Unlimited access to AI generation is a $35 per month add-on. The SEO add on also costs $35 per month for advanced search engine optimization features.
⚠️ Pricing conflict flagged: Some sources still list an older Frase price sheet with a Basic plan at $14.99 per month, a Team plan at $44.99, and Enterprise at $114.99. Those figures do not match our canonical data. We publish the CSV rates above. Check the Frase pricing page before you buy.
Fraseの主な利点
Here is what makes this content tool worth considering:
- SERP research in minutes: The research tool reads the first 20 SERP results for the same keyword. It returns a brief with essential terms and topics to cover.
- Content gaps you can act on: Frase compares your own content against rivals. It flags topics your original article is missing.
- A topic score for existing content: Import a live page and Frase scores it. The score shows how your article stacks up against high ranking content.
- 質問 research for search intent: Search a target keyword and Frase surfaces real questions people ask. Great for finding new angles.
- Google Search Console integration: Available on every plan. It links your pages to the queries already sending organic traffic.
- Multilingual coverage: Frase supports English, Spanish, French, German, Italian, Dutch, Portuguese and Danish.
- Faster content production: Some users report producing an article four to five times faster than before.
The homepage sets the ピッチ clearly for any content creator weighing this software.

Grammarlyとは何ですか？
Grammarly is a writing assistant powered by artificial intelligence.
It checks spelling and grammar as you type, in almost any app.
The editor flags a misspelled word, a clumsy sentence, or the wrong tone.
It also explains why, so you learn from your mistakes.
A browser extension covers Google Docs, Gmail, and most web 編集者.
The Grammarly mobile app and Grammarly Keyboard cover your phone.
Runner Up: Grammarly
Grammarly catches errors everywhere you write. The free version has no word count cap. Paid adds tone suggestions and plagiarism detection.
Grammarlyの価格
Grammarly offers three tiers. One of them costs nothing.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料 | 0米ドル | Basic spelling grammar and punctuation fixes |
| プロ | 12米ドル | Writers who want tone, clarity and plagiarism checks |
| 企業 | 営業担当者へのお問い合わせ | Teams needing shared style rules and admin controls |
価格は2026年7月に確定しました。
無料トライアル: The free version is permanent, so a separate trial is not needed.
返金保証: Refunds are handled case by case through support after you cancel.
📌 注記： The paid tier is listed as Pro in our data. Many readers still search for Grammarly Premium, which is the older name for the same premium subscription. A Grammarly Premium review and a Grammarly Pro review describe the same premium features.
⚠️ 警告： Plans renew automatically. Cancel from your account settings before the renewal date, because a refund after renewal is not guaranteed.
Grammarlyの主なメリット
Here is what this writing software does well:
- No cap on the free version: The free tier has no word count limit for spelling and grammar checks. Most rivals meter that.
- リアルタイムフィードバック： Corrections appear as you write. You stay on the actual content instead of hunting for errors.
- Explains every fix: Each correction comes with a short reason. That teaches context rather than just handing you an answer.
- Tone and audience matching: It reads your writing style and suggests the right tone for your audience. Passive 声 gets flagged too.
- Plagiarism detection: The plagiarism checker in the premium version compares your written work against billions of web pages.
- Works where you already write: Microsoft Word, Google Docs and Slack are supported without copy and paste.
- Multiple languages on mobile: The keyboard handles English, Spanish, French, German, Portuguese and Italian.
Grammarly Premium helps most when you need polished writing in a few clicks rather than a full rewrite.

- No keyword research, SERP data, or SEO scoring of any kind
機能比較
Ready for a closer look at Frase vs Grammarly? We walk through eleven areas, then pricing. Each one shows where the two tools stop overlapping.
| 特徴 | フレーズ | 文法 |
|---|---|---|
| 開始価格 | 月額49ドル | $0 (free), $12/mo Pro |
| 無料版 | ❌ | ✅ |
| キーワードリサーチ | ✅ | ❌ |
| SERPアナライザー | ✅ | ❌ |
| 文法チェッカー | ❌ | ✅ |
| 盗作チェッカー | ❌ | ✅ |
| AIライター | ✅ | ✅ |
| ブラウザ拡張機能 | ❌ | ✅ |
| 最適な用途 | SEO content tools and briefs | Grammar, spelling and tone |
1. AIライティングツール
フレーズ: The AI article wizard drafts a full article from your brief. You can also generate section by section from a new document. Reviews describe the AI writing as functional but generic, so plan on editing.
文法: Its generative AI rewrites what you already wrote rather than producing a full draft from a keyword. Prompts sit inside the editor and respond in a few clicks. The output stays closer to your own 声.
⚠️ 警告： Neither AI writer produces publish-ready copy. Both need a human pass before the article goes live.
2. Research and SERP Analysis
フレーズ: This is the core of the product. Frase reads the top ranking search results for your target keyword and returns headings, essential terms and monthly search volume context. That research feeds straight into content briefs.
文法: There is no SERP research here at all. The closest thing is its citation finder, which locates sources for claims you have already written. Useful for academics, useless for keyword research.
3. Content Optimization vs Grammar Checking
フレーズ: Import an existing page and Frase scores it against the top 20 results for the same keyword. The topic score climbs as you add missing terms. Formatting on your original article stays intact during import.
文法: The grammar checker handles subject-verb agreement, misplaced modifiers and commonly confused words. It reads surrounding context to pick the correct option. No SEO scoring exists in the product.
4. Outline Building and Snippets
フレーズ: The outline builder pulls headings from competitors so you can assemble a content outline by dragging them across. You can also let the AIアシスタント generate one. It takes minutes, not an afternoon.
文法: Snippets store reusable blocks of 文章 you paste with a shortcut. Handy for support teams sending the same message repeatedly. It is a productivity feature, not a structural one.
5. Question Research and Search Intent
フレーズ: The question finder surfaces what people actually ask around a topic. That is the fastest read on search intent you will get inside one screen. It is also a reliable source of new content ideas.
文法: Proofreading is the equivalent step here, and it happens after the writing exists. It reviews clarity, vocabulary and sentence structure across the whole document. Nothing about it touches search intent.
6. Title Ideas and Word Count
フレーズ: The blog title generator produces title ideas from your keyword, and a separate template drafts a meta description. Both aim at seo friendly articles rather than clever headlines. Expect to rewrite one in three.
文法: A free word counter runs alongside the editor and reports reading time and readability. It is a small thing that writers on a brief word count use daily. No title generation is offered.
7. Templates and Tone Suggestions
フレーズ: Templates cover intros, product descriptions, summaries and アウトリーチ copy. They speed up repetitive stuff for any content writer working to a deadline. Tone control is basic compared with a dedicated writing assistant.
文法: Tone suggestions are the standout feature. Set a goal and the tool nudges your written content toward the right tone for that audience. It will also flag when a message reads colder than you meant.
8. SEO Analytics and Plagiarism Detection
フレーズ: Google Search Console integration ships on every plan, so you can see which pages already earn clicks. Pair that with the SERP data and you get a workable seo workflow. There is no originality checking.
文法: The plagiarism checker compares your own work against billions of indexed pages. Plagiarism detection sits behind the paid tier only. Students and editors lean on it more than marketers do.
9. Paragraph Generation and Paraphrasing
フレーズ: The paragraph generator writes a block of text from a heading and a short prompt. It is fine for filler sections and weak for anything requiring a story or first-hand detail. Credits apply unless you buy unlimited access.
文法: The paraphrasing tool rewrites a sentence you already have, usually shorter and clearer. Because it works from your text, the result keeps your meaning. That makes sense for editing rather than creating content.
10. Citations and Essay Checking
フレーズ: No citation features exist. Frase is aimed at marketers chasing rankings, not at students formatting a bibliography. If you need references, you are pairing it with another tool.
文法: A citation generator formats references in the major academic styles from a link or title.
There is also a free エッセイ and paper checker for anyone submitting academic written work.
11. AI Detection and Humanizing
フレーズ: Frase does not score how machine-written a draft looks. Given that its own AI generated drafts read flat, that gap matters if your team publishes at volume.
文法: AI 検出器 estimates how much of a document looks machine-generated before you hand it in.
A separate AI humanizer then loosens stiff phrasing so the result reads closer to a person.
12. 価格設定とコスト
This is the widest gap in the whole comparison. One tool is free to try forever. The other starts at $49 per month.
| プランレベル | フレーズ | 文法 |
|---|---|---|
| 無料 | ❌ | 0米ドル |
| 入場料支払い済み | Starter, $49/mo | Pro, $12 USD |
| 中級クラス | Professional, $129/mo | ❌ |
| 最高級 | Scale, $299/mo | Enterprise, Contact Sales |
フレーズ: You pay for research, not for word polish. Against MarketMuse and Surfer SEO the entry price still reads reasonable for what the SEOツール returns. Budget for the add-ons if you want unlimited AI generation.
文法: At $12 the paid tier is the cheapest thing in this comparison, and the free version already covers spelling and grammar. You are buying correctness, not rankings. For most writers that is an easy call.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| 予算が限られている | 文法 | Free version, then $12 |
| キーワード調査と概要説明 | フレーズ | Reads top 20 results |

| オーガニックトラフィックの増加 | フレーズ | Topic score and gap analysis |
| Academic written work | 文法 | Citations and plagiarism checks |
| 初心者向けのセットアップ | 文法 | Install once, no learning curve |
💰 あなたの予算

私たちのレビューで取り上げられなかったこと
This comparison focused on solo writers, フリーランサー and small content teams. We did not test the Frase Scale plan, Grammarly Enterprise, or admin controls for large organisations. We also did not track bug fixes or release notes across the past year, so small interface details may have moved. If you publish in a language other than English, your writing experience with either tool may differ from what we describe here.

🏆 優勝者：FRASE
Frase wins 4 out of 7 categories.
最適な用途: keyword research, content briefs, and content optimization tools for teams that live on organic traffic
Frase wins here because the job most readers are hiring for is ranking, and Grammarly cannot do that at all. Frase AI turns a keyword into a brief, an outline and a rough draft in one sitting.
Grammarly is the better product at what it does. Nothing in Frase comes close to its grammar checker, and the free version alone is more useful than most paid editors.
In the real world, plenty of people end up owning both. Use Frase to decide what to write, then run the draft through Grammarly before it ships.
If you can only buy one, ask what you hope to achieve. Rankings point to Frase. Clean, great writing points to Grammarly.
