Grammarly คืออะไร?
Grammarly is a writing assistant powered by artificial intelligence.
It runs as a browser extension, a desktop editor, and a mobile keyboard.
The grammar checker flags a misspelled word, a broken sentence, or a clumsy phrase as you type.
It also reads context, so it can tell commonly confused words apart.
Tone suggestions help you match the right tone to your audience.
Grammarly offers a free version and a paid tier, now branded Pro rather than Premium.
Grammarly Premium is the old name for that paid tier, and you will still see it used.
Grammarly Premium helps most with rewrites, vocabulary choices, and plagiarism checks.
The company publishes user trust guidelines covering how your ข้อความ is stored and used.
This Grammarly review video shows the editor in action.
🏆 ผู้ชนะ: Grammarly
Real-time spelling and grammar help inside the apps you already use. The free version alone fixes most everyday mistakes. Pro adds plagiarism detection and full-sentence rewrites.
ราคาของ Grammarly

ประโยชน์หลักของ Grammarly
Reviewers find it helpful for catching the small stuff you stop seeing after a third read. Here is where it earns its place in a writing workflow:
- Deeper grammar checks: It catches subject-verb agreement and misplaced modifiers, not just surface errors. That goes well past basic spell-checking.
- Teaching, not just fixing: Every suggestion comes with an explanation. You learn from your own work instead of clicking accept blindly.
- Clarity and concision: It spots padding and offers tighter alternatives, plus vocabulary swaps. It also pushes passive เสียง toward active voice.
- Works where you write: Direct integration with Microsoft Word, Google Docs, and Slack. No copy and paste needed.
- Grammarly Keyboard: The Grammarly mobile app covers spelling, grammar, and concision in English, Spanish, French, German, Portuguese, and Italian.
- Document editor: Cloud document storage, personal writing statistics, and plagiarism detection against billions of web pages.
- Generative AI on tap: AI assistance can draft a short message or rewrite a paragraph in a few clicks. For example, you can shorten a rambling reply before you send it.

เปรียบเทียบคุณสมบัติ
ทั้งคู่ เครื่องมือ AI, yet they barely overlap. That makes the feature comparison unusual, because each one wins the categories the other ignores. Here are the key features side by side.
| คุณสมบัติ | ไรท์โซนิค | แกรมมาร์ลี่ |
|---|---|---|
| ราคาเริ่มต้น | $39 | $0 (Free), $12 Pro |
| แผนฟรี | ✅ | ✅ |
| นักเขียนบทความ AI | ✅ | ❌ |
| โปรแกรมตรวจสอบไวยากรณ์ | ❌ | ✅ |
| คำแนะนำเกี่ยวกับน้ำเสียง | ✅ | ✅ |
| สืบค้นคําค้น | ✅ | ❌ |
| การวิเคราะห์ช่องว่างเนื้อหา | ✅ | ❌ |
| โปรแกรมตรวจสอบการลอกเลียนแบบ | ❌ | ✅ |
| ส่วนขยายเบราว์เซอร์ | ✅ | ✅ |
| เหมาะสำหรับ | Bulk content generation | Polished writing and editing |
1. Core Purpose and Output
ไรท์โซนิก: This is a generation engine. You give it a topic and relevant details, and it produces website content, blog articles, email copy, ad copy, video scripts, and e-commerce copy. Writesonic AI is built to create, not to correct.
แกรมมาร์ลี: This is a correction layer. It reads written work you already produced and improves clarity, grammar, and word choice. It will not write content from scratch or produce a 2,000-word article for you.
2. AI Article Writer and Long Form Content
ไรท์โซนิก: The AI article writer asks what kind of piece you want, how much detail to include, and which target keywords to hit. It runs in depth research, then hands you an outline before writing. Article Writer 6.0 drafts fact-checked posts of 1,500 words or more in under a minute.
แกรมมาร์ลี: Its AI writing tools handle short drafts and rewrites, not full articles. Generative AI here is best for a quick email or a tightened paragraph. For article writing at volume, it is the wrong tool.
3. Grammar Checker and Proofreading
ไรท์โซนิก: There is no dedicated grammar checker. The AI model writes clean sentences most of the time, but nothing scans your own typing for errors. You still need a separate editor for spelling grammar checks.
แกรมมาร์ลี: Proofreading is the whole point. It flags a misspelled word ทันที, catches complex grammar issues, and explains why each fix matters. Every suggestion can be applied or dismissed, so you can ignore anything that does not fit.
4. Tone Suggestions and Brand Voice
ไรท์โซนิก: You set the tone before generating, from professional to funny to dramatic. Brand voice training teaches the AI your house style so output stays consistent. It shapes content before it exists.
แกรมมาร์ลี: Tone suggestions work after the fact. It reads your draft, tells you how it lands, and nudges you toward the right tone for your reader. That is more useful for a tense email than for a landing page.
5. SEO Optimization and Keyword Research
ไรท์โซนิก: The keyword research tool shows search volume and traffic potential. An SEO checker then scores your draft and suggests fixes for readability and keyword use. SurferSEO data flows straight into the editor.
แกรมมาร์ลี: No SEO features at all. It will not tell you what search engines want or how to structure seo content. Pair it with an เครื่องมือ SEO if ranking matters.
💡 เคล็ดลับสำหรับมืออาชีพ: If your goal is ranking, Writesonic is the excellent starting point. If your goal is clean copy, Grammarly is the great tool. Plenty of teams pay for both.
6. Content Gap Analysis and Site Auditing
ไรท์โซนิก: Content gap analysis shows which topics competitors cover that you do not. An ตรวจสอบ tool surfaces technical issues, and automated internal linking suggests where to connect pages. It also connects to Google Search Console for performance data.
แกรมมาร์ลี: Nothing comparable here. Its analytics stop at personal writing statistics inside your account. Site-level strategy is out of scope.
7. AI Chat Tools and Real Time Data
ไรท์โซนิก: Chatsonic handles market research, การวิเคราะห์คู่แข่ง, and content ideas. Unlike static chat tools, it can pull real time data into an answer. Higher tiers add AI visibility tracking that shows how AI models cite your brand.
แกรมมาร์ลี: AI assistance sits inside the editor rather than in a research chat. You can ask it to shorten, expand, or restate a passage. It will not go out and research a topic for you.
8. Plagiarism Detection and Original Work
ไรท์โซนิก: No plagiarism checker is bundled. Since the tool produces ai generated content, teams in academia or publishing usually run a separate check anyway. That is an extra cost and an extra step.
แกรมมาร์ลี: Plagiarism detection compares your written content against billions of web pages. It is a premium feature, missing from the free tier. Citation support helps you credit sources properly.
9. Integrations, Interface and Ease of Use
ไรท์โซนิก: A Chrome extension lets you draft inside email and ที่อยู่เชื่อมโยง without switching tabs, which makes for a faster writing experience. The user interface is clean, and G2 reviews frequently praise it as beginner friendly. Advanced users get templates for Google Ads, Facebook ads, email sequences, and even a ยูทูบ ชื่อ.
แกรมมาร์ลี: The browser extension works across most sites the moment you log in. It also runs in Word, Google Docs, Slack, and desktop apps. The Grammarly Keyboard brings the same checks to your phone in multiple languages.
⚠️ คำเตือน: Grammarly needs an internet connection. If the extension stops appearing, a browser update is usually the cause, and bug fixes normally arrive within days.
10. การกำหนดราคาและต้นทุน
This is the least close category in the whole comparison.
| ชั้น | ไรท์โซนิค | แกรมมาร์ลี่ |
|---|---|---|
| ฟรี | แผนฟรีแบบจำกัด | 0 ดอลลาร์สหรัฐ |
| ชำระค่าเข้าชมแล้ว | Lite — $39 | Pro — $12 USD |
| กลาง | Standard — $79 | — |
| สูงกว่า | Professor — $199 | — |
| สูงสุด | Advanced — $399 | — |
| กำหนดเอง | ธุรกิจขนาดใหญ่ — การกำหนดราคาแบบกำหนดเอง | ธุรกิจขนาดใหญ่ — ติดต่อฝ่ายขาย |
ไรท์โซนิก: You are paying for production capacity, and the ladder climbs fast. Lite at $39 suits one person, while agencies chasing unlimited access land on Advanced at $399. Enterprise adds custom data retention.
แกรมมาร์ลี: Pro at $12 is the only consumer tier, and the free version covers a lot on its own. For a single writer, the yearly difference against Writesonic Lite is roughly $324.

สิ่งที่บทวิจารณ์ของเราไม่ได้กล่าวถึง
This comparison looked at solo writers and small teams. We did not test enterprise rollouts, admin controls, or how either tool handles a fifty-seat account. We also did not measure ranking outcomes over months, which is the only honest way to judge SEO claims. If you write fiction, note that both tools were built for ธุรกิจ and academic work, so your experience may differ from ours.

🏆 ผู้ชนะ: GRAMMARLY
Grammarly wins 5 out of 7 categories.
เหมาะสำหรับ: everyday writing, นักเรียน and client work, polished writing at a low price
Grammarly takes the overall win because it helps more people, more often, for less money. Writing happens in email, chat, and documents every day across the world, which makes it a valuable resource for almost anyone. As mentioned earlier, great writing still needs a human, but this removes the friction.
Writesonic wins where it should. Nothing in Grammarly produces a 5,000-word draft, runs content gap analysis, or checks keyword volume. For agencies chasing high quality content at scale, that gap is the whole story.
So pick by job, not by score. Choose Grammarly if your writing already exists and needs sharpening. Choose Writesonic if you need to create content at a volume no human can match. We hope that makes the decision easier to achieve.
