Writesonicとは何ですか?
Writesonic is an AI writing tool that launched in 2020.
Writesonic AI covers content creation services for blogs, ads, and email.
Its user interface puts article writing behind a few simple prompts.
The article writer builds outlines with H1, H2, and H3 headings first.
Then it does in depth research on competitors before drafting.
That research step is what separates it from other ai writers.

The video below walks through the dashboard and its key features.

機能比較
Ready for a closer look at Jenni AI vs Writesonic? We walk through nine areas plus price, so you can see where each ai writing assistant earns its keep.
| 特徴 | ジェニー・AI | ライトソニック |
|---|---|---|
| 開始価格 | 月額12ドル | $39 |
| 無料プラン | ✅ 200 words/day | ✅ 10,000 words/month |
| In Text Citations | ✅ | ❌ |
| 内蔵の盗作チェッカー | ✅ | ❌ |
| キーワードリサーチ | ❌ | ✅ |
| コンテンツギャップ分析 | ❌ | ✅ |
| PDF Uploads | ✅ | ❌ |
| 画像生成 | ❌ | ✅ Photosonic |
| 言語 | 30+ | 25+ |
| 最適な用途 | 学術論文 | SEOコンテンツ |
1. Drafting Engine
ジェニーAI: The ai autocomplete suggests the next line as you type. You stay in the driver’s seat, which helps you overcome writer’s block without handing over the whole page. Critics note the suggestions can feel like a glorified autocomplete service.
ライトソニック: The ai article writer takes a topic and returns a full draft. You choose depth, target keywords, and relevant details up front. It can write articles of 1,500 to 5,000 words in minutes. The tool’s ability to generate content at that speed is its main draw.

2. Citations and Output Polish
ジェニーAI: You add citations from a library built out of your own sources. The tool inserts in text citations while you write, then keeps the reference list in sync. Some reviewers argue the citation search is thinner than a dedicated reference manager.
ライトソニック: There is no citation engine here. Instead a humanizer rewrites ai generated content so it reads less robotic. That matters, because reviewers say raw output needs a human pass before it becomes quality content. Editing is a crucial step in the content creation process here.

3. AI Chat Assistants
ジェニーAI: AskJenni is an agentic research chat that reads your uploaded papers. Ask it to summarize a section and it answers from the file, not the open web. That keeps research and writing inside one document.
ライトソニック: The Chatsonic ai chat assistant pulls real time data from the web. Teams use it for competitor checks, content ideas, and quick market questions. Among chat tools aimed at marketers, it is the more useful of the two.

4. Working With Your Own Files
ジェニーAI: Upload a PDF or a .bib file and generate text that references it directly. This is the feature students lean on for a research paper with fixed sources. Writesonic has no equivalent.
ライトソニック: Content gap analysis compares your site against rivals and lists topics you have missed. It is aimed at a content strategy rather than a single document. The output doubles as a valuable resource for planning a quarter of blog content.

5. Outlines and SEO Planning
ジェニーAI: The outline builder turns a prompt into section headings. It works well for essays, personal statements, and speeches. There is no keyword data behind it, so it will not help you rank on search engines.
ライトソニック: The SEO AI agent plans structure around live SERP data and handles automated internal linking. Google Search Console connects in, so drafts target pages you already rank for. This is how drafts arrive tuned for search rather than as generic filler.

6. Languages and AI Visibility
ジェニーAI: Over 30 languages are supported, including Spanish, German, French, and Chinese. Non-native writers use it to fix tone in academic essays. Translation happens inside the editor.
ライトソニック: Coverage sits at 25+ languages. Higher tiers add AI visibility tracking, which shows how each ai model cites your brand. It then suggests fixes, which is useful as AIツール reshape search.

7. Editing Commands and Audits
ジェニーAI: Highlight a line and run an AI command to shorten, expand, or 言い換え it. You can shift tone without leaving the paper. It is a light touch approach to editing.
ライトソニック: その 監査 and issue fixer crawls your website content and flags technical problems. It then applies fixes in bulk. Nothing in Jenni AI touches published pages this way.

8. Citation Styles and Keyword Research
ジェニーAI: Switch between APA, MLA, IEEE, Chicago, and Harvard with one click. Every citation reformats across the document. Journals and universities usually demand one fixed style, so this saves real time.
ライトソニック: The volume explorer handles keyword research with search volume and traffic estimates. Pair it with the seo checker and you get readability grades too. Neither exists in Jenni AI.

9. PDF Fetch and Source Library
ジェニーAI: PDF fetch grabs the full text behind a reference so you can read and cite without leaving the tab. Combined with pdf uploads, it builds a working research library fast.
ライトソニック: Source handling is limited to what Chatsonic finds live. There is no personal library and no way to pin a paper to a draft. For anything citation-heavy this is a hard stop.
⚠️ 警告: Neither tool replaces your own judgement. Both are better used as a helping hand while you keep control of accuracy and final edits.
10. 価格設定とコスト
Let’s put the plans side by side.
| ティア | ジェニー・AI | ライトソニック |
|---|---|---|
| 無料 | 月額0ドル | 無料プランあり |
| 入場料支払い済み | 無制限プラン:月額12ドル | Lite: $39 |
| 中 | ❌ | Standard: $79 |
| 高い | ❌ | Professor: $199 / Advanced: $399 |
| カスタム | チーム&機関:カスタム | 企業向け:カスタム価格設定 |
ジェニーAI: One paid tier at $12/month keeps the decision simple. For a 学生 on a fixed budget that is the whole appeal. You are paying for writing, not a marketing suite.
ライトソニック: Entry cost is more than three times higher. That buys keyword tools, audits, images, and voice in one account. For a 仕事 that has to write content weekly, the maths can still work.
さまざまなシナリオ

🛟 サポートオプション
G2 reviews flag slow support replies at Writesonic, especially on billing. Neither service publishes a phone line for standard plans.

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 and small teams. We did not test custom data retention terms, enterprise onboarding, or how either ai model performs across a full year of output. Our notes reflect the July 2026 versions, and both products ship changes often. If you manage a large agency, your priorities will differ from ours.
