⚡ 快速结论：
- 定价： Scite costs $20 monthly, or $12/month on the yearly plan. Paperguide starts at $0 with a free plan, then $12/month billed annually.
- 最适合： Scite suits researchers who need evidence behind citations. Paperguide suits students writing papers who also want a reference manager.
- 主要区别： Scite labels each citing paper as supporting, contrasting, or mentioning. Paperguide handles the writing process instead.
- 我们的选择： Scite, because no other tool here checks whether the literature agrees with a claim.
PhD students compare Scite and Paperguide for one reason.
They are drowning in research papers and running out of hours.
Both tools promise to save so much time during a literature review.
But they attack the problem from opposite ends.
Scite checks the evidence behind citations in scientific literature.
Paperguide writes, cites, and stores your academic papers in one place.

Scite是什么？
Scite is a citation analysis tool built for scientific literature.
It helps researchers discover and understand research articles through Smart Citations.
A Smart Citation shows the context of the citation from the citing paper.
It adds a classification describing whether the article provides supporting or contrasting evidence.
A deep learning model reads full-text articles to sort those citation statements.
Scite has analyzed and indexed over 1 billion citation statements to date.
The short video below walks through how Scite works in a real search.
🏆 Winner: Scite
See who supports a claim and who disputes it. Smart Citations turn raw citation counts into real evidence.
Scite 定价
Scite keeps its pricing simple. There are two published options.
| 计划 | 价格 | 最适合 |
|---|---|---|
| 月度计划 | $20 | Short projects and one-off reference checks |
| 年度计划 | 每月12美元 | Students and academics working all year |
价格已于2026年7月核实。
免费试用： Scite lists no free plan in the two options above. Check the signup page for any trial offer running at the time you join.

- 自定义仪表盘： Track a field over time, spot the experts, and follow related work as new citations land.
- Structured insights: Scite can pull PICO terms or named biomarkers into tables you shape yourself.
- Badges everywhere: Scite badges appear on Google Scholar and PubMed, so smart citation counts show up while you search.
- API 访问： Teams can pipe Scite 数据 into their own systems and tools.

| 最适合 | Checking evidence | Writing papers |
1. Smart Citations and Citation Context
引用： This is the core of the product. Every citing paper carries a label that provides supporting or contrasting signal, plus the sentence it came from. You read the evidence, not a tally.
论文指南： It auto-cites papers as you write and links each claim to its source. There is no classification describing agreement or dispute between studies.
⚠️ 警告： A high citation count is not proof of quality. Some of those citations may be disputing the finding.
2. 人工智能研究助理
引用： 这 人工智能助手 answers questions and cites real papers from its indexed database. Reviewers rate the quality of results highly, though some have hit fabricated quotes.
论文指南： Chat with PDF lets you interrogate one paper or a folder of them. It explains complex topics in plain words and pulls key points into notes.
3. Literature Search and Discovery
引用： Search runs across scientific literature and patents, so you catch applied work others miss. Forward and backward citation chaining make finding related work fast.
论文指南： AI search reads your question in natural language and returns academic content from multiple sources. Semantic Scholar supplies much of that pool of reliable sources.
⚠️ 警告： Some users found Scite weaker than Google Scholar for broad discovery. Run both for the first pass of a literature search.
4. Literature Review Workflow
引用： Journal pages and rankings show where a publication sits in its field. That context shortens the screening stage of the literature review process.
论文指南： A dedicated literature review module walks you from question to draft. It groups papers by theme and drafts the synthesis for you to edit.
5. Reference Check and Citation Generation
引用： Reference Check takes your manuscript and audits every source. It tells you if a cited paper was retracted, disputed, or given an editorial notice.
论文指南： The AI citation 发电机 formats references in thousands of styles. Traditional reference managers do this too, but few pair it with a writing assistant.
6. Data Extraction and Dashboards
引用： Custom dashboards track a topic over time and surface the experts in it. Structured tables can hold PICO terms or biomarkers pulled from the papers.
论文指南： Extract data pulls sample sizes, methods, and findings into a comparison grid. It is the faster route to deeper insights across twenty papers.
7. AI Writing and Document Generation
引用： There are no drafting tools here. Scite feeds the writing process with evidence, then you write elsewhere.
论文指南： Full document generation turns an outline and a folder of sources into a draft. Real time collaboration features let co-authors shape the same ideas together.
8. Deep Research Reports
引用： Reports come as dashboards and email alerts rather than documents. You get told when new evidence lands on a topic you follow.
论文指南： Deep research reports process papers from several databases and return a sourced write-up. It is the closest thing here to a first draft of a review.
The AI version of the same report adds automatic structure and summaries.
9. Plagiarism and Academic Integrity
引用： No plagiarism tool exists. Integrity here means source integrity, which is what Reference Check protects.
论文指南： A free plagiarism checker runs against your draft before submission. Students on tight deadlines rate this among its more powerful features.
10. Browser Extension and Research Tracking
引用： The extension shows how an article has been cited while you read it online. Badges appear over open access pages and over paywalled content in your library.
Funding and institution views sit beside those dashboards for anyone tracking a field.
论文指南： The Chrome extension saves papers straight into your library from any site. G2 customers point to the user friendly interface as the reason they stayed.
11. 定价与成本
Let’s put the plans side by side.
| 计划 | 斯赛特 | 纸指南 |
|---|---|---|
| 自由的 | ❌ | 每月0美元，按年计费 |
| 入场费 | Yearly Plan — $12/month | Plus — $12/per month, billed annually |
| 更高层级 | Monthly plan — $20 | Pro — $24/per month, billed annually |
| 风俗 | ❌ | Enterprise Custom Plan |
引用： One product, two ways to pay. At $12/month on the yearly plan you get every feature, which keeps the maths simple for grant budgets.
论文指南： The free plan is the real draw for students. Plus matches Scite at $12, and Pro doubles that for unlimited storage and heavier limits.

我们的评测没有涵盖的内容
This comparison focused on individual students, academics, and small labs. We did not test Enterprise deployments, API rate limits, or how either tool handles non-English literature at scale. Our notes reflect the July 2026 versions and the pricing published at that date. If you manage a department licence, your priorities will differ from what we covered here.

🏆 WINNER: SCITE
Scite wins 5 of the 8 scored categories.
最适合： Systematic reviews, manuscript reference checks, and tracking a field over time
Scite and Paperguide are not really rivals. They sit at different points of the same research process.
Scite is the evidence layer. It tells you whether the literature backs a claim or fights it, and it flags sources you should not cite at all.
Paperguide is the production layer. It reads your PDFs, stores your references, and drafts academic writing around them.
Paperguide is the better pick if you are writing papers on a 学生 budget. The free plan alone makes it worth an account.
But if your reputation rides on the sources in your reference list, Scite is the one to pay for.

常见问题解答
scite 有什么用途？
It is used to check how a paper has been cited. Smart Citations show whether later studies support, contrast, or simply mention the original finding.
Scite是免费的还是收费的？
It is paid. Two plans exist: $20 month to month, or $12 per month on the yearly plan. No free tier appears in the published pricing.
What is the difference between Scite AI and ChatGPT?
One is built on a citation database of real papers with evidence labels. The other is a general 聊天机器人 that can invent references if pushed.
是什么人工智能让你能够与PDF文件对话？
Paperguide, previously ChatWithPDF, does this. Upload a paper and ask questions in plain language. The free plan covers basic chat and AI search.
Scite AI值得投资吗？
Worth it for anyone publishing or writing a thesis. Reference Check alone can stop you citing a retracted study. Casual readers will find Paperguide cheaper.
