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.

O que é Scite?
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.

| Ideal para | Checking evidence | Writing papers |
1. Smart Citations and Citation Context
Scite: 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.
Guia em papel: It auto-cites papers as you write and links each claim to its source. There is no classification describing agreement or dispute between studies.
⚠️ Aviso: A high citation count is not proof of quality. Some of those citations may be disputing the finding.
2. Assistente de Pesquisa em IA
Scite: O assistente de IA answers questions and cites real papers from its indexed database. Reviewers rate the quality of results highly, though some have hit fabricated quotes.
Guia em papel: 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
Scite: Search runs across scientific literature and patents, so you catch applied work others miss. Forward and backward citation chaining make finding related work fast.
Guia em papel: 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.
⚠️ Aviso: 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
Scite: Journal pages and rankings show where a publication sits in its field. That context shortens the screening stage of the literature review process.
Guia em papel: 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
Scite: Reference Check takes your manuscript and audits every source. It tells you if a cited paper was retracted, disputed, or given an editorial notice.
Guia em papel: The AI citation gerador 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
Scite: 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.
Guia em papel: 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
Scite: There are no drafting tools here. Scite feeds the writing process with evidence, then you write elsewhere.
Guia em papel: 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
Scite: Reports come as dashboards and email alerts rather than documents. You get told when new evidence lands on a topic you follow.
Guia em papel: 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
Scite: No plagiarism tool exists. Integrity here means source integrity, which is what Reference Check protects.
Guia em papel: 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
Scite: 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.
Guia em papel: 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. Preços e Custos
Let’s put the plans side by side.
| Plano | Scite | Guia de papel |
|---|---|---|
| Livre | ❌ | US$ 0 por mês, cobrado anualmente. |
| Entrada paga | Yearly Plan — $12/month | Plus — $12/per month, billed annually |
| Nível superior | Monthly plan — $20 | Pro — $24/per month, billed annually |
| Personalizado | ❌ | Enterprise Custom Plan |
Scite: 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.
Guia em papel: The free plan is the real draw for students. Plus matches Scite at $12, and Pro doubles that for unlimited storage and heavier limits.

O que nossa avaliação não abordou
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.
Ideal para: 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 estudante 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.
