- 私たちのおすすめ： Frase, rated 4.3 against 4.2, because most buyers here want organic traffic rather than academic writing help.
この2つ AIツール rarely show up on the same shortlist.
Frase is built to create SEO optimized content that ranks.

Yet people compare them because both promise faster writing with AI.
The gap between them decides which one your money should go to.
概要
This Frase vs SciSpace comparison covers pricing, features, and ease of use.
It also breaks down who each ai tool actually serves.
弊社のライター陣は、両方のプラットフォームを実際に操作して検証しました。
それらのメモは、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。
Everything else comes from published specs, documentation, and G2 reviews.
Fraseとは何ですか？
Frase is an AI writing アシスタント built around search engine optimization.
それは2017年にマサチューセッツ州ボストンで開発されました。
You give it a target keyword and it studies the competition.
Frase pulls the top 20 Google results for that same keyword.
From there it builds a content outline and a list of essential terms.
The built-in ai 作家 then drafts sections against that plan.
Multilingual optimization covers English, Spanish, French, German, Italian, Dutch, Portuguese, and Danish.
The Frase review video below walks through that workflow start to finish.
🏆 受賞者：Frase
Research, brief, and draft in one place. Nine seo content tools sit behind a single editor. Built for people who publish weekly.
フレーズ価格設定
2026年におけるFraseの費用は以下のとおりです。
| プラン | 価格 | 最適な用途 |
|---|---|---|
| スターター | 月額49ドル | Solo content creator work |
| プロ | 月額129ドル | Small teams publishing weekly |
| 規模 | 月額299ドル | Agencies running a heavy seo workflow |
価格は2026年7月に確定しました。
無料トライアル: No free version and no trial are offered.
返金保証: A 5-day money-back window applies instead of a trial.
📌 注記： Google Search Console integration and WordPress publishing are included on every plan. The SEO add on costs $35 per month and unlocks deeper keyword research data, including monthly search volume.
⚠️ Pricing conflict: Our research notes list a Basic plan at $14.99, a Team plan at $44.99, and an Enterprise tier at $114.99. Those figures do not match our verified pricing data above, which we treat as canonical. Check the Frase pricing page before you buy, since legacy plans and regional rates both circulate online.
⚠️ 警告： Unlimited access to the ai writer is a separate $35 per month add-on. Base plans cap you at roughly 10,000 AI characters monthly, which is only 1,500 to 2,000 words.
Fraseの主な利点
Here is what makes Frase worth a look:
- SERP research in minutes: The research tool reads the first 20 results for your target search query. It returns headings, word count targets, and all the keywords rivals share.
- Topic score: A single number shows how your optimized content compares to competitors. It updates live as you write.
- Question finder: Frase surfaces real questions people ask about a topic. That gives you angles that match search intent.
- Works on existing content: You can import an original article and keep its formatting. Frase then suggests fixes rather than a rewrite.
- Short-form templates: Blog title ideas, intros, and a meta description ジェネレータ sit next to the editor. Handy for the small pieces that eat time.
- スピード： Some users report producing content four to five times faster. That gain comes mostly from research, not drafting.
The editor itself keeps research and drafting on one screen.
私たちのチームが気づいたこと
Our writer signed up for Frase and ran two real briefs through it. Here is what stood out from that hands-on time:
フレーズの長所と短所
✅ メリット
- Analyzes the first 20 SERP results to build a content brief
- Google Search Console integration is included on every plan
- Content briefs and outlines take minutes instead of hours
- Topic score shows how your draft compares to top ranking pages
❌ デメリット
- No free version and no trial, only a 5-day money-back guarantee
- Unlimited AI writing costs an extra $35 per month
- Drafts often read generic and need heavy editing
SciSpaceとは何ですか?
SciSpace is an ai research assistant for academics.
It is run by the company Typeset, and older guides still use that name.
The database holds metadata for over 200 million research papers.
More than 50 million open access full-text PDFs sit inside it.
Semantic search lets you ask a research question in plain language.
You get answers backed by citations, not a bare link list.
強調表示が分かりにくい 文章, math, or tables and it returns simple explanations.
The video below shows that reading flow in action.
サイスペース
Read, question, and cite papers in one workspace. Every answer carries a source. Best for thesis and literature review work.
SciSpaceの価格設定
SciSpace offers four tiers, and one of them is free.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 基本 | $0 | Testing search and limited chat usage |
| チーム | $8 | Small labs sharing a collection |
| プレミアム | $12 | Unlimited chats and citation generation |
| 高度な | $70 | Heavy data extraction and institutional access |
価格は2026年7月に確定しました。
無料トライアル: The Basic plan acts as the free version, with no card needed.
返金保証: Refunds are handled case by case through support.
📌 注記： The free tier gives access to search across scientific literature. Unlimited SciSpace Copilot chats and unlimited citation generation sit behind the paid tiers.
⚠️ 警告： Published rates for the premium tier are often quoted as $12 to $20 per month. Confirm your regional price at checkout before your card is charged.
SciSpaceの主なメリット
Here is what makes SciSpace worth considering:
- PDFでチャット： Answers point back to the exact section of a paper. That context makes claims easy to verify.
- Citation generator: In-text and reference citations cover more than 9,000 styles. It ensures research papers stay properly attributed.
- Follow up questions: You can keep asking until the details click. Good for clearing doubts on dense methods sections.
- Data extractor: It pulls data points from several papers into custom tables. That removes a lot of the hard work in a review.
- Shared libraries: Teams co-edit with Admin, Member, and Owner roles. Summaries and suggestions stay visible to everyone.
- Turnitin check: Text similarity checking is built in for submissions. It flags potential academic misconduct before a journal does.
The workspace itself keeps your collection, chat, and drafts side by side.

機能比較
Ready for the detailed comparison of Frase vs SciSpace?
We cover nine features plus cost, so you can see where each AIアシスタント earns its keep.
| 特徴 | フレーズ | サイスペース |
|---|---|---|
| 開始価格 | 月額49ドル | $0 (paid from $8) |
| 無料プラン | ❌ | ✅ |
| SERP分析 | ✅ | ❌ |
| Academic Citations | ❌ | ✅ |
| AIライター | ✅ | ✅ |
| コンテンツスコアリング | ✅ | ❌ |
| AI検出器 | ❌ | ✅ |
| Google Search Console | ✅ | ❌ |
| 最適な用途 | Ranking on search engines | Reading and citing papers |
1. Research and Source Analysis
フレーズ: The research tool reads the first 20 SERP results for your target keyword. It returns headings, questions, and shared terms in one brief. This is the part of Frase AI that most reviewers rate highest.
サイスペース: Its topic finder searches scientific literature instead of search results. You describe a research question and it surfaces relevant papers with detailed insights attached. The analysis is academic, not competitive.
2. AI Writing and Drafting
フレーズ: The AI article wizard turns a brief into a full article draft. You can also start writing from a blank document and let it fill gaps. Reviewers say the ai generated content reads generic without edits.
サイスペース: Its ai writer drafts academic sections from papers you have saved. Output leans formal and sticks close to your sources. It will not help you with creating content for a blog.
💡 プロのヒント: Treat both AI models as first-draft engines. Paste output into Google Docs, cut the filler, then rebuild the argument in your own words.
3. Content Optimization and Scoring
フレーズ: A topic score rates your draft against top ranking search results. The number moves as you add missing terms and lift your word count. Few content optimization tools make progress this visible.
サイスペース: There is no ranking score here at all. The paraphraser adjusts tone and length of a passage instead. That helps clarity in academic writing, not seo optimization.
4. Outlines, Briefs, and Structure
フレーズ: 概要 ビルダー copies headings from competitors or drafts new ones. Content briefs land in minutes rather than an afternoon. Every content writer on a deadline feels that difference.
サイスペース: Its workspace structures the literature review process instead. Teams analyze papers together and share summaries as they go. Live activity tracking adds a to-do checklist for each thesis chapter.
5. Questions and Follow Up
フレーズ: The question finder pulls real queries people type about a topic. Those questions map neatly to search intent and FAQ blocks. It is a quiet reason Frase produces seo friendly articles.
サイスペース: Chat with PDF answers questions from a specific paper. You can ask follow up questions until the method makes sense. Each reply carries citations so you can check the source.
6. Citations and Data Sources
フレーズ: SEO analytics link your own content to live performance data. Google Search Console integration shows which pages already earn organic traffic. There is no academic citation layer at all.
サイスペース: Its citation generator handles in-text and reference formats across 9,000+ styles. That covers most journals researchers submit to. Turnitin similarity checking sits alongside it for the submissions part of the publishing process.
7. Templates and Short-Form Output
フレーズ: Templates cover intros, product blurbs, and social copy. Each one opens as a new document so nothing clutters your main draft. For a content creator shipping daily, that ai content generation shortcut adds up.
サイスペース: The agent gallery offers task-specific agents rather than marketing templates. One agent searches, another drafts, another compares papers. It is a versatile tool, but the focus stays academic.
8. Working With Content You Already Have
フレーズ: Import a published post and the paragraph generator rewrites weak sections. Original formatting survives the import, so your actual content stays intact. This is the fastest path to refreshed, high ranking content.
サイスペース: Upload your existing PDF library and pick the data points you want. The data extractor drops them into custom tables for side-by-side reading. It also helps you discover related papers you missed.
9. Quality Checks and Integrations
フレーズ: The blog title generator tests title ideas before you commit. WordPress publishing and Search Console both connect natively. Missing, though, is any check on whether text reads as ai generated.
サイスペース: A built-in ai detector scores text before you submit it. A Chrome extension pulls papers straight from journal sites. As a review tool it fits neatly beside other modern tools in a lab.
⚠️ 警告： An ai detector score is a signal, not a verdict. Human-written passages get flagged too, so never treat a number as proof either way.
10. 価格設定とコスト
Here are the plans side by side.
| ティア | フレーズ | サイスペース |
|---|---|---|
| 無料 | ❌ なし | 基本料金：0ドル |
| 入場料支払い済み | Starter: $49/mo | Teams: $8 |
| 中 | Professional: $129/mo | プレミアム：12ドル |
| トップ | Scale: $299/mo | Advanced: $70 |
フレーズ: You pay a business-tool price for a 仕事 outcome. Compared with rival seo content tools, for example Surfer SEO and マーケットミューズ, Frase sits mid-pack rather than cheap. Budget for the $35 add-on if you want unlimited drafting.
サイスペース: 学生 pricing, student scope. You can test the whole search layer for free before paying anything. Even the top tier costs less per month than Frase’s entry plan.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| To create seo optimized content | フレーズ | SERP-driven briefs and scoring |
| To read and cite papers | サイスペース | 2億件以上の論文データベース |
| 限られた予算 | サイスペース | Free tier, $8 entry plan |
| Faster content production | フレーズ | Research and drafting in one editor |
| Plagiarism and AI checks | サイスペース | ターンイティン プラスAI detector built in |
| 初心者向けのセットアップ | フレーズ | One keyword starts the workflow |
💰 あなたの予算
Frase asks $49 before you write a word. SciSpace lets you test everything free, so the risk sits entirely on Frase’s side.
🔌 あなたの技術スタック
Frase plugs into WordPress and Search Console, which suits a publishing team. SciSpace plugs into your browser and your PDF pile instead.
📝 あなたの文章スタイル
Marketing writers want structure and keyword coverage from their content creation process. Academics want accuracy and traceable sources, which is a different job entirely.
🎓 あなたの経験レベル
Frase gives beginners a clear path from keyword to draft. SciSpace assumes you already know how to read a methods section.
🆓 無料トライアルとデモ
Start with the SciSpace free tier if you are unsure. With Frase, use the 5-day refund window as your trial and test a real brief immediately.
🛟 サポートオプション
G2 reviews describe Frase support as responsive when interface glitches appear. SciSpace handles refunds and billing questions through the same support channel.

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 individual writers and small teams. We did not test developer access, API workflows, or institutional licensing at either company. Enterprise contracts and custom rates were also out of scope. Our notes reflect the July 2026 versions, and both ai writing tools ship changes often, so check current plans before you buy.

🏆 優勝者：FRASE
Frase wins 4 out of 6 categories with a 4.3 rating against 4.2.
最適な用途: blog teams, agency writers, and anyone chasing organic traffic
These two products answer different questions, so the winner depends on your job title. Frase is the SEOツール. It exists to create high ranking content and it does that well.
SciSpace is the research assistant. For a thesis, a systematic review, or a stack of unread PDFs, no content tool from the marketing world comes close.
SciSpace also wins outright on price, and its free tier is genuinely usable. If money is tight and your work is academic, take it and skip the rest of this page.
For everyone publishing to the web, Frase is the better buy. Its research, scoring, and AI generation sit in one editor, and that is where the time savings actually come from.
