ราคาของ Grammarly
Here is what Grammarly costs in 2026. Three tiers, one simple ladder.
| วางแผน | ราคา | เหมาะสำหรับ |
|---|---|---|
| ฟรี | 0 ดอลลาร์สหรัฐ | Basic spelling grammar checks |
| โปร | 12 ดอลลาร์สหรัฐ | Tone, rewrites and plagiarism detection |

ราคาได้รับการยืนยัน ณ เดือนกรกฎาคม 2569
ทดลองใช้งานฟรี: The free version runs with no time limit and no card required.
รับประกันคืนเงิน: Refunds are handled case by case through the support team.
📌 บันทึก: The free tier gives unlimited word counts for spelling and grammar checks. Many rivals cap that. The paid tier adds tone suggestions, full sentence rewrites and a plagiarism checker.
⚠️ หมายเหตุเกี่ยวกับราคา: Our CSV lists the paid tier as Pro at $12 USD. Older marketing pages and a typical Grammarly premium review call the same tier Premium. We use the CSV figures throughout this article and flag the naming gap here rather than picking one source silently.
ประโยชน์หลักของ Grammarly
Here is what makes Grammarly worth a paid account:
- Context aware corrections: It tells apart commonly confused words using the surrounding context. It also catches subject verb agreement and misplaced modifiers.
- Tone suggestions: Grammarly analyses your writing style and tone against your intended audience. You pick the right tone before you hit send.
- Clarity edits: It marks unnecessary words and offers shorter alternatives. Passive เสียง gets flipped to active voice for stronger writing.
- Teaching feedback: Each suggestion carries a short explanation. That turns editing into a lesson instead of a silent fix.
- Plagiarism detection: The premium version checks your written content against billions of web pages. The free version does not include this.
- ใช้ได้ทุกที่: The Grammarly keyboard, the desktop app and the browser extension cover almost every place you write.
- หลายภาษา: The mobile keyboard handles English, Spanish, French, German, Portuguese and Italian.
The benefits page below shows how those pieces fit together.
สิ่งที่ทีมของเราสังเกตเห็น
Our writer signed up for a Grammarly premium subscription and used it across email, blog drafts and academic writing. The short version: Grammarly premium helps most on tone and rewrites, less on ideas. Here is what stood out from that hands on time:
ข้อดีและข้อเสียของ Grammarly
✅ ข้อดี

- Grammarly keyboard covers six languages on mobile
- Plagiarism checker is bundled into the paid plan
❌ ข้อเสีย

Paperguide คืออะไร?
Paperguide is an ai research assistant built for academic papers.
You upload papers and it answers questions about them in chat.
Paperguide reads long PDFs and returns ai generated summaries.
It also acts as a reference manager for your whole library.
Folders, tags and annotation tools keep research materials sorted.
The platform launched in 2023 and now serves students and professionals.
Here is the walkthrough before we get to the numbers.
🥈 Runner Up: Paperguide
Chat with research papers, run an ai search and cite sources. Built for the literature review process.
ราคาคู่มือกระดาษ
Paperguide offers four tiers. All paid rates below are billed annually.
| วางแผน | ราคา | เหมาะสำหรับ |
|---|---|---|
| ฟรี | 0 ดอลลาร์ต่อเดือน เรียกเก็บเงินรายปี | Casual users testing chat with PDF |
| นอกจากนี้ | 12 ดอลลาร์ต่อเดือน ชำระรายปี | Students running a literature review |
| โปร | 24 ดอลลาร์ต่อเดือน ชำระรายปี | Researchers who process papers in bulk |

ราคาได้รับการยืนยัน ณ เดือนกรกฎาคม 2569
ทดลองใช้งานฟรี: A free plan is available with no card needed at signup.
รับประกันคืนเงิน: Refund terms are set out in the billing pages at checkout.
📌 บันทึก: The higher tier is where unlimited storage and unlimited references sit. That matters if you upload papers by the hundred rather than the dozen.
⚠️ คำเตือน: Every paid rate is quoted at the annual billing date. Monthly billing costs more, so check the toggle before you pay.
ประโยชน์หลักของ Paperguide
Here is where Paperguide earns its place in a research workflow:
- แชทกับไฟล์ PDF ของคุณ: Ask questions and pull key points from a paper in seconds. That can save hours on a dense methods section.
- AI search across sources: The ai search pulls from academic databases like Semantic Scholar. It surfaces reliable sources rather than blog posts.
- Efficient reference management: Import, tag and export references in one place. Traditional reference managers rarely bundle an ผู้ช่วย AI alongside.
- Citations at scale: Generate citations in thousands of styles with ai assisted formatting. It auto cites as you draft.
- Literature review workspace: Build a review from multiple sources and compare findings side by side. Deeper insights come from the extract ข้อมูล tables.
- Built in plagiarism check: A plagiarism checker ships with the platform to protect academic integrity.
- ส่วนขยาย Chrome: Save a paper from any journal site without leaving your browser.
The benefits overview below maps those pieces to real research needs.
สิ่งที่ทีมของเราสังเกตเห็น
Note: We have not had extended hands on time with Paperguide yet. Everything above comes from published documentation, the pricing pages and G2 reviews. We will update this section once our writer has run a full literature review inside the platform.
ข้อดีและข้อเสียของ Paperguide
✅ ข้อดี
- Chat with PDF turns a long paper into answers you can act on
- Reference manager, ai writer and citation เครื่องกำเนิดไฟฟ้า sit in one workspace
- AI search pulls from academic databases instead of the open web
- Free plan lets you test the workflow before paying
❌ ข้อเสีย
- No live grammar checker inside everyday apps
- Pro tier costs double the Plus tier
- Overkill for anyone who is not writing academic content
เปรียบเทียบคุณสมบัติ
These two tools barely overlap. That makes the comparison easier than it looks.
We walk through nine features plus pricing, so you can match each one to your own workflow.
| คุณสมบัติ | แกรมมาร์ลี่ | คู่มือกระดาษ |
|---|---|---|
| Starting paid price | 12 ดอลลาร์สหรัฐ | 12 ดอลลาร์/เดือน |
| เวอร์ชันฟรี | ✅ | ✅ |
| Live grammar checker | ✅ | ❌ |
| Tone suggestions | ✅ | ❌ |
| โปรแกรมตรวจสอบการลอกเลียนแบบ | ✅ (ชำระเงินแล้ว) | ✅ |
| Reference manager | ❌ | ✅ |
| แชทกับไฟล์ PDF | ❌ | ✅ |
| Literature search | ❌ | ✅ |
| ส่วนขยายเบราว์เซอร์ | ✅ | ✅ (Chrome) |
| เหมาะที่สุดสำหรับ | Everyday writing | งานวิจัยเชิงวิชาการ |
1. Grammar Checker and Spelling Accuracy
แกรมมาร์ลี: This is the core job. The grammar checker catches a misspelled word, a run on sentence and subject verb agreement problems as you type. It also separates commonly confused words by reading the context around them.
คู่มือเอกสาร: There is no live spell check layer here. The ai writer produces clean prose, but nothing watches your typing across other apps. You would still paste drafts elsewhere for a final proofreading pass.
⚠️ คำเตือน: No checker is perfect. Grammarly supplements writing skill and does not replace it, so review each correct suggestion before you accept it.
2. Tone Suggestions and Writing Style
แกรมมาร์ลี: Tone suggestions read your message against the audience you set. The tool flags a stiff line, a hedge, or a note that lands colder than you meant. It also nudges passive voice into active voice.
คู่มือเอกสาร: Academic tone is the default and there is no dial to change it. That suits a thesis. It does not help with a อีเมลเย็น or a client message.
3. Proofreading and Document Editing
แกรมมาร์ลี: The document editor gives writing statistics, clarity scores and full sentence rewrites. You can ignore any flag with one click. Every suggestion carries a short reason, which is how the tool teaches vocabulary and structure over time.
คู่มือเอกสาร: Full document generation drafts an entire section from your sources. That is a different job from editing. You get a first draft fast, then you polish it somewhere else.
4. การตรวจจับการลอกเลียนแบบ
แกรมมาร์ลี: Plagiarism detection sits behind the paid tier. It checks your own work against billions of web pages. The free version leaves this out entirely.
คู่มือเอกสาร: A free plagiarism checker is included rather than gated. For a นักเรียน on a tight budget, that removes one more subscription from the pile.
5. Citations and Reference Manager
แกรมมาร์ลี: There is a citation generator for common styles. It formats what you feed it. There is no library, no folders and no way to store references for later.
คู่มือเอกสาร: This is a full reference manager with an ai citation generator on top. It supports thousands of styles and multiple file formats. Traditional reference managers handle storage well but rarely add ai powered tools beside it.
6. Literature Review and Research Papers
แกรมมาร์ลี: A citation finder helps you track down a source you half remember. That is the limit. There is no literature search and no way to compare findings across multiple sources.
คู่มือเอกสาร: The literature review process runs inside one workspace. You gather research papers, pull key points and build the review from there. For complex topics, that structure beats forty open browser tabs.
7. Chat With PDF and AI Search
แกรมมาร์ลี: The ai writing tools draft and rewrite text you supply. They do not read a PDF for you. If your ideas are already on the page, this is the faster route to polished writing.
คู่มือเอกสาร: Chat with PDF is the headline feature and the reason many people arrive. Ask a question, get an answer with the passage attached. The ai search then widens the net for easy access to related work.
8. AI Assistance and Generative AI
แกรมมาร์ลี: Generative ai handles rewrites, tone shifts and idea prompts. An ai humanizer and an ai เครื่องตรวจจับ sit alongside. The ai assistance is aimed at everyday writing, not at academic sourcing.
คู่มือเอกสาร: The artificial intelligence here is pointed at sources. It ranks papers, drafts summaries and answers follow up questions. That is ai powered research rather than general purpose writing help.
9. Extract Data and Deep Research Reports
แกรมมาร์ลี: The paraphrasing tool reworks a paragraph you already have. Useful for a tangled sentence. It cannot pull numbers out of a table or build a report from a stack of PDFs.
คู่มือเอกสาร: Deep research reports pull findings from several papers into one document. These are powerful features for a systematic review.
💡 เคล็ดลับสำหรับมืออาชีพ: The extract data view turns sample sizes and outcomes into a sortable table. Check it against the original paper before you cite anything.
10. การกำหนดราคาและต้นทุน
Let’s put the plans side by side.
| ชั้น | แกรมมาร์ลี่ | คู่มือกระดาษ |
|---|---|---|
| ฟรี | 0 ดอลลาร์สหรัฐ | 0 ดอลลาร์ต่อเดือน เรียกเก็บเงินรายปี |
| ชำระค่าเข้าชมแล้ว | Pro $12 USD | Plus $12/per month, billed annually |
| Upper paid | — | Pro $24/per month, billed annually |
| ธุรกิจ | ธุรกิจขนาดใหญ่: ติดต่อฝ่ายขาย | Enterprise: Custom Plan |
แกรมมาร์ลี: One paid tier keeps the choice simple. At $12 USD you get tone, rewrites and plagiarism detection. The free version stays generous enough that many people never upgrade.
คู่มือเอกสาร: Entry pricing matches at $12. The jump to $24 buys the volume limits that heavy researchers need. Budget for the higher tier if you handle papers weekly rather than once a term.
สถานการณ์ต่างๆ
| หากคุณต้องการ... | เลือก | ทำไม |
|---|---|---|
| Everyday email and blog editing | แกรมมาร์ลี่ | Live checks in every app |
| To chat with research papers | คู่มือกระดาษ | Only one that reads PDFs |
| Tone control for clients | แกรมมาร์ลี่ | Audience based tone suggestions |
| A reference manager | คู่มือกระดาษ | Library, tags and auto citing |
| A free tool that stays useful | แกรมมาร์ลี่ | Unlimited free grammar checks |
| Mobile writing | แกรมมาร์ลี่ | Keyboard on iOS and แอนดรอยด์ |
💰 งบประมาณของคุณ
Both entry plans land at $12, so price alone will not settle this. The real question is whether you need the $24 Paperguide tier for volume.
🔌 อุปกรณ์เทคโนโลยีของคุณ
Grammarly offers desktop apps, a browser extension and the Grammarly mobile app keyboard. Paperguide lives in the browser with a Chrome extension for saving papers.
📝 ขั้นตอนการเขียนของคุณ
If your writing process starts with reading, Paperguide saves you the most time. If it starts with a blank page and ends in edits, Grammarly wins.
🎓 ระดับประสบการณ์ของคุณ
Grammarly has a user friendly interface that needs no setup. Paperguide asks you to build a library first, which takes an afternoon.
🆓 ทดลองใช้งานและเดโมฟรี
Test both on a real assignment before you pay. Official docs and ยูทูบ videos cover the setup steps for each tool.
🛟 การสนับสนุนและนโยบายความเป็นส่วนตัว
Grammarly publishes user trust guidelines covering how your text is handled, and ships regular bug fixes. Read the privacy pages for both before you upload sensitive work.

สิ่งที่บทวิจารณ์ของเราไม่ได้กล่าวถึง
This comparison focused on individual writers, students and small teams. We did not test enterprise rollouts, custom style rules or the real time collaboration features either platform offers at the team level. Our writer had hands on time with Grammarly only, so the Paperguide notes rest on documentation and G2 reviews. If you are running a lab of thirty academics, your priorities will differ from what we covered here.

🏆 ผู้ชนะ: GRAMMARLY
Grammarly wins 5 of 7 categories.
เหมาะสำหรับ: everyday editing, email and client work, students who want mistake free drafts without a second subscription
These are two different products with one word in common. Grammarly polishes the words you already wrote. Paperguide helps you find and understand the words other people wrote.
Grammarly takes the win because more people need it more often. Great writing starts with clean sentences, and the free tier alone handles the small stuff for anyone in the world with a browser.
Paperguide is excellent at what it does. If a thesis is your story for the next two years, it will save you real hours. We hope this side by side helps you achieve that without paying for both.
