QuillBotとは何ですか？

Learneo acquired QuillBot in September 2021.
The tool now reports over 30 million monthly active users.
QuillBot works as a paraphraser tool, grammar checker, summarizer and citation ジェネレータ.
The paraphrase tool sits at the centre of that lineup.
QuillBot helps you reword a sentence without losing what it means.
Used carefully, that habit sharpens your own writing skills.
Here is a closer look at how the writing process feels in practice.
The screen below shows the main workspace.

Paperguide とは何ですか?
Paperguide is an ai research assistant built for academic work.
It is an ai powered platform for students, academics and professionals.
It launched in 2023 and now reports over 500,000 users.
The platform helps you find, read and sort research papers faster.
You can upload papers and chat with them like a document assistant.
It also doubles as a reference manager with folders and tags.
Product Hunt named it #1 Product of the Day after launch.
Watch how the research process runs inside the app.
This is the workspace where most of that research happens.
🥈 Runner Up: Paperguide
Built for literature review work. Chat with papers, pull quotes, and keep every citation in one library.

|---|---|---|
| 無料 | 月額0ドル、年間請求 | Testing chat and summaries |
| プラス | 月額12ドル（年間請求） | Students in a literature review |
| プロ | 月額24ドル（年間請求） | PhD researchers and academics |

価格は2026年7月に確定しました。
無料トライアル: Yes. A free plan lets you test the AIアシスタント お支払い前に。
返金保証: Refund terms sit inside the billing page. Read them before an annual purchase.
📌 注記： Paid tiers add unlimited references and unlimited storage. That matters if you keep hundreds of academic papers in one library.
⚠️ 警告： Every paid price above is an annual rate. Month-to-month billing usually costs more, so confirm the total at checkout before the card is charged.
Paperguideの主な利点
These are powerful features for anyone running ai powered research week after week.
Saved libraries also stay searchable for future projects.
Here is where Paperguide earns its place beside other ai powered tools:
- AI search across real sources: The ai search tool pulls from academic databases like Semantic Scholar. That gives easy access to reliable sources instead of invented ones.
- Literature review support: It builds tables, themes and ai generated summaries across multiple sources. The literature review process gets shorter.
- Reference management: Folders, tags and annotation tools replace the scattered folders of traditional reference managers.
- Citations at scale: Thousands of citation styles are supported with AI-assisted formatting.
- Plagiarism checker built in: A checker sits inside the platform, so academic content gets a second pass before submission.
- Chrome拡張機能： A chrome extension brings the whole research toolkit into your browser while you read.
- Wider media support: Document summaries and video summarization cover formats that Elicit and SciSpace skip, including ユーチューブ ビデオ。
私たちのチームが気づいたこと
Note: We have not had extended hands-on time with Paperguide yet. Everything above comes from published documentation, the Paperguide website and third-party listings. We will add first-hand notes once our writer completes a full literature search inside the platform.

機能比較
Ready for a closer look at QuillBot vs Paperguide? We compare ten areas, from paraphrasing to the literature review process, so you can match each tool to your own research needs.
| 特徴 | クイルボット | ペーパーガイド |
|---|---|---|
| Starting paid price | 月額4.17 | 月額12ドル（年間請求） |
| 無料プラン | ✅ | ✅ |
| Paraphrasing modes | ✅ (7 modes) | ❌ |
| 文法チェッカー | ✅ | ❌ |
| Chat with uploaded papers | ❌ | ✅ |
| Literature review builder | ❌ | ✅ |
| 引用ジェネレーター | ✅ | ✅ |
| 盗作チェッカー | ✅ | ✅ |
| Chrome拡張機能 | ✅ | ✅ |
| 最適な用途 | Everyday writing and editing | Academic research workflows |
1. Paraphrasing and Rewriting Modes
クイルボット: This is the core product. Standard, fluency, formal mode, simple, creative mode, expand mode and shorten mode each change the output in a different direction. You can compare paraphrases side by side before you accept one.
ペーパーガイド: There are no writing modes here. Instead it generates full document drafts from sources you have already collected, which is a different job entirely.
⚠️ 警告： A paraphrasing tool does not make copied text original. Rewording a source without a citation still counts as plagiarism at most universities.
2. Grammar Checking and Editing
クイルボット: The grammar checker runs live while you type. It catches spelling, punctuation and complex sentences that run too long. G2 reviews note the suggestions are sometimes weak on tone, so read each fix before accepting it.
ペーパーガイド: Editing is not the focus. You get an ai writer for academic writing, but no dedicated grammar layer for polishing a text message or a cover letter.
💡 プロのヒント: QuillBot also ships an ai writing keyboard on mobile. The quillbot keyboard carries the same keyboard modes, plus text and emoji prediction, adjustable prediction settings and dark themes. Reviews of the iOS build are mixed, so test quillbot’s mobile keyboard on a short draft first.
3. Summarizing and Reading Papers
クイルボット: The summarizer condenses an article into key points or a short paragraph. It works well on one document at a time, which suits blog research more than a full literature search.
ペーパーガイド: You upload papers and then chat with them directly. Answers cite the page they came from, which makes it easier to verify claims in dense academic papers.
4. AI Chat and AI Search
クイルボット: QuillBot’s AI Chat answers questions and drafts ideas inside the same workspace. It is a general ai assistant, so it does not search a database of research papers.
ペーパーガイド: Its ai search queries academic databases and returns papers with abstracts. Because results come from indexed sources, you get deeper insights on complex topics rather than a general answer.
5. Literature Review and Data Extraction
クイルボット: There is no literature review builder. The PDF converter helps you move files between formats, which is useful prep work but not analysis.
ペーパーガイド: This is where the platform earns its price. It groups papers by theme, drafts a literature review outline, and can extract データ from tables into a single comparison grid.
The extraction view below turns scattered tables into one grid.
6. Citations and Reference Management
クイルボット: The free citation generator covers APA, MLA and Chicago. You can create citations quickly, but there is no library that stores them between projects.
ペーパーガイド: Papers you read get cited automatically, and the reference manager keeps every entry in one place. Efficient reference management is the main reason researchers pick it over a plain writing app.
Style selection sits in a separate panel.
7. Plagiarism Checking and Academic Integrity
クイルボット: The plagiarism checker is a premium feature. It scans a draft and flags passages that match published sources, which helps when you have paraphrased heavily.
ペーパーガイド: A free plagiarism checker is included, which fits its academic audience. Combined with automatic citations, it reduces the odds of an accidental integrity flag.
8. Translation and Humanizing AI Text
クイルボット: Real-time translation covers 45+ languages, including French, Spanish, German and Chinese. That helps if you draft in one language and submit in another.
A separate tool targets ai generated content that reads too stiff.
ペーパーガイド: Multiple languages are supported for reading and summarizing sources. There is no humanizer, since the platform is aimed at citation-backed academic content rather than tone editing.
9. Deep Research Reports
クイルボット: There is no report engine. QuillBot Flow keeps notes, sources and drafts together, but you assemble the argument yourself.
ペーパーガイド: Deep research reports pull from multiple sources and return a structured draft with references attached. It is the closest thing here to a first-pass research analyst.
Report depth settings live in the same panel.
10. 価格設定とコスト
Let’s put the plans side by side.
| 計画レベル | クイルボット | ペーパーガイド |
|---|---|---|
| 無料 | $0（永久無料） | 月額0ドル、年間請求 |
| 入場料支払い済み | Premium: 4.17 per month | Plus: $12/per month, billed annually |
| Upper paid | ❌ | Pro: $24/per month, billed annually |
| チーム | Team Plan: Custom Pricing | Enterprise: Custom Plan |
クイルボット: One paid tier keeps the decision simple, and it is the cheaper entry point of the two. For a 学生 writing essays weekly, the premium version pays for itself quickly.
ペーパーガイド: You pay more, but the price buys database search, unlimited storage and reference tools. That gap makes sense for a thesis and looks expensive for a blog post.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| 限られた予算 | クイルボット | より安価なエントリープラン |
| Faster rewriting | クイルボット | Seven paraphrasing modes |
| Papers you can question | ペーパーガイド | Chat with uploaded PDFs |
| A full literature review | ペーパーガイド | Theme grouping and citations |
| Everyday content creation | クイルボット | Editing tools built in |
| 初心者向けのセットアップ | クイルボット | 学習曲線が短い |
💰 あなたの予算
QuillBot Premium is the cheaper commitment of the two. Paperguide Plus costs more, so the extra research features have to earn that gap.
🔌 あなたの技術スタック
QuillBot plugs into Microsoft Word, Google Docs and most web browsers. Paperguide lives in your browser through its extension and a web workspace.
📝 あなたの文章スタイル
If you draft first and refine later, QuillBot refines faster across different writing styles. If you read first and write last, Paperguide fits the research process better.
🎓 あなたの経験レベル
QuillBot has a user friendly interface that new users pick up in minutes. Paperguide asks more of you upfront, because a reference library needs structure.
🆓 無料トライアルとデモ
Both have a free plan, so test them on the same assignment. Run one source through each and see which output you trust.
🛟 サポートオプション
QuillBot support draws mixed feedback, especially around refunds. Paperguide is smaller, so expect email-first help rather than instant chat.

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 students, academics and solo writers. We did not test institutional licensing, real time collaboration features across large teams, or long-term data safety practices at either company. Our notes reflect the July 2026 versions of both platforms, and features change. Pricing pages move quickly, so check the date on any review before you trust a figure. If you manage a lab or a content team of twenty, your priorities will differ from what we covered here.

🏆 WINNER: QUILLBOT
QuillBot wins 4 out of 7 categories.
最適な用途: essays and coursework, professional communication, and everyday content creation
QuillBot and Paperguide are built for different halves of the same job. QuillBot handles the words. Paperguide handles the sources behind them.
There is no single best ai for every writing job. Reviews swing from calling QuillBot an amazing tool to calling its output flat, which is what happens when 30 million people use one product each month.
QuillBot takes the overall win because it helps more people, more often, for less money. It is a useful tool the moment you have a draft, and the free version alone will save time on short assignments.
Paperguide is the better buy for one specific reader. If you are deep in a thesis and drowning in references, it can save hours per week that QuillBot cannot touch.

よくある質問
QuillBotは不正行為をしているのか？
Rewriting your own draft is fine. Rewording someone else’s work to hide the source breaks academic integrity rules at most schools. Check your institution’s policy first.
QuillBotは本当に無料ですか？
Yes, the free tier is free forever. It limits word counts and modes. Premium unlocks every mode, the plagiarism scan and faster processing.
QuillBotの欠点は何ですか？
Output can read awkward on technical passages. Reviews also flag a glitchy iOS app and slow refund handling. Always reread rewritten text before submitting.
PDFファイルと会話できるAIとは何ですか？
Paperguide does this. You upload papers, ask questions, and get answers linked to the source page. It also works across several papers at once.
QuillBotにお金を払う価値はありますか？
If you write weekly, yes. The premium tier costs less than most rivals and covers rewriting, grammar and citations. Occasional writers can stay free.
