O que é Scite?
Scite is a citation platform for scientific literature.
It helps researchers discover and understand research articles through Smart Citations.
A Smart Citation shows the context of the citation itself.
It also adds a classification describing whether a citing paper agrees or disagrees.
Scite has analyzed and indexed over 1 billion citation statements.
That work runs on a deep learning model trained on full-text papers.
🥈 Runner Up: Scite
Built for finding related work fast. Every citing paper is tagged as supporting, contrasting or mentioning evidence.
Preços da Scite
Here is what Scite costs in 2026. There are two plans.
| Plano | Preço | Ideal para |
|---|---|---|
| Plano mensal | $20 | Short projects and one-off literature review work |
| Plano Anual | US$ 12/mês | PhD students and labs tracking research all year |
Preços verificados em julho de 2026.
Teste grátis: Scite runs a limited trial. There is no free forever tier, so budget for a paid month.
Garantia de reembolso: Refunds are handled case by case through the support team.
📌 Observação: Both plans unlock the same features. The yearly plan simply cuts the monthly cost by $8. Many universities also buy institutional access, so check with your library before paying yourself.
⚠️ Aviso: Several users on review sites report problems with billing and subscription renewals. Cancel from your account settings before the renewal date rather than by email.
Key Benefits of Scite
Here is what makes Scite worth a look:
- Citações inteligentes: Each entry displays the context of the citation. It marks whether the article provides supporting or contrasting evidence.
- Retraction flags: Scite marks any publication that was retracted or corrected. That adds a credibility check most search tools skip.
- Verificação de referências: Upload a manuscript and Scite verifies whether your references were retracted or disputed.
- Structured insights: It pulls PICO terms or biomarkers from papers into custom tables you control.
- Dashboards and alerts: Track a topic over time and get email alerts when new citations land.
- Badges where you already search: Scite badges appear on Google Scholar and PubMed as you browse.
- Acesso à API: Labs can pull Scite dados straight into their own tools and resources.
The short video below walks through those benefits in the live product.

Scite Pros & Cons
✅ Prós
- Smart Citations show whether each citing paper supports or disputes a claim
- Over 1 billion citation statements indexed from full-text sources
- Reference Check catches retracted sources before you submit
- Browser extension and badges work inside Google Scholar and PubMed
❌ Contras
- No free plan, so there is no long-term free version to test
- Some users report fabricated quotes and nonexistent sources from the assistant
- Search accuracy and billing renewals draw repeat complaints on review sites
O que é o QuillBot?
QuillBot is an AI writing assistant for students and professionals.
It runs on natural language processing and reports over 30 million monthly active users.
The paraphraser tool rewrites text while keeping the original meaning.
QuillBot features include a grammar checker, summarizer, translator and plagiarism checker.
It was founded in 2017 at the University of Illinois.
Learneo acquired it in September 2021.
🏆 Winner: QuillBot
Seven writing modes, grammar checking and citations in one workspace. The free version never expires.
Preços do QuillBot
Here is what QuillBot pricing looks like in 2026. Three tiers.
| Plano | Preço | Ideal para |
|---|---|---|
| Livre | $0 (Grátis para sempre) | A escola project or light daily editing |
| Premium | US$ 4,17 por mês | Students writing papers and content creation work |
| Plano de equipe | Preços personalizados | Departments and agencies buying seats together |
Preços verificados em julho de 2026.
Teste grátis: No card is needed. The free version runs forever with lower word limits.
Garantia de reembolso: A refund window applies to new Premium subscriptions. Request it from the support team.
📌 Observação: The free version caps paraphrasing at a set word count per turn and locks the stronger writing modes. QuillBot Premium removes those caps and opens every mode.
⚠️ Pricing conflict: Our research notes list a $8.33 to $20 monthly range depending on subscription length. Our CSV records Premium at $4.17 per month. We use the $4.17 figure throughout this article. Check the checkout page before you buy, since regional rates and term length both move the price.
Principais benefícios do QuillBot
Eis o que torna o QuillBot uma opção a ser considerada:
- Seven writing modes: Standard, fluency, formal mode, simple, creative mode, expand mode and shorten mode. You can compare paraphrases write to write before picking one.
- Grammar checker: It flags errors as you type. Reviews call the editing help a useful tool for weaker writing skills.
- Resumo: Paste a long article and pull out key points in seconds.
- Citação gerador: Create citations in APA, MLA or Chicago without leaving the page.
- Verificador de plágio: Scan a draft for copied passages before you submit it.

Comparação de recursos
These two tools sit at opposite ends of the same workflow. Scite handles the reading and the evidence. QuillBot handles the drafting and the editing.
Here are ten areas where the difference shows up.
| Recurso | Scite | QuillBot |
|---|---|---|
| Preço inicial | $12/month yearly | $0 free, $4.17/month |
| Plano Gratuito | ❌ | ✅ |
| Citações inteligentes | ✅ | ❌ |
| Ferramenta de paráfrase | ❌ | ✅ |
| Corretor gramatical | ❌ | ✅ |
| Verificador de plágio | ❌ | ✅ |
| Verificação de Referências | ✅ | ❌ |
| Retraction Flags | ✅ | ❌ |
| Extensão do navegador | ✅ | ✅ |
| Ideal para | Literature review and evidence checks | Writing papers and daily editing |
1. Research Discovery and AI Assistants
Scite: The Scite assistant answers questions using indexed papers and returns real citations with each claim. It is built for finding related work rather than general chat. Users searching a narrow field say it cuts so much time out of the first pass.
QuillBot: QuillBot’s AI Chat answers writing questions and drafts passages on request. It does not search a scholarly index, so it will not surface a scientific article for you. Treat it as a drafting partner, not a discovery engine.
⚠️ Aviso: Some users have reported fabricated quotes and nonexistent sources from Scite’s assistant. A few also found it less useful for academic research than Google Scholar. Open every reference before you cite it.
2. Citations and Evidence
Scite: Smart Citations sort every citing paper into supporting, contrasting or mentioning buckets. You see the sentence that surrounds each reference, which tells you how the citation was actually used. It supports both directions of citation chaining: forward chaining finds newer work citing a source, and backward chaining tests the quality of a paper’s own references.
QuillBot: A citação gerador formats entries in APA, MLA and Chicago style. It builds a bibliography from a link, title or DOI in a few clicks. It formats what you already found, but it will not judge the quality of the evidence.
3. Paraphrasing and Writing Modes
Scite: There is no paraphrase tool here. Scite will not rewrite a sentence or adjust your writing styles. Any rewording still happens in your own word processor.
QuillBot: The paraphrasing tool offers standard, fluency, formal mode, simple, creative mode, expand mode and shorten mode. Each one changes how aggressively QuillBot refines your sentence. Creative mode moves furthest from the source, while formal mode suits professional communication.
4. Grammar Checking and Editing
Scite: No grammar checker is included. Scite works on the sources behind your argument, not the prose on the page.
QuillBot: Checking grammar happens live as you type, with fixes offered inline. It untangles complex sentences and flags weak agreement. Some reviews note that suggestions can be poor, so read each fix before accepting it.
5. Summarizing and Translation
Scite: Structured insights pull PICO terms or named biomarkers out of papers into custom tables. That is closer to data extraction than summarising, and it only works on academic articles.
QuillBot: The summarizer condenses any long text into key points or a short paragraph. It handles a research paper, a report or a news article equally well.
Translation sits beside it and covers more than 45 languages.
6. Plagiarism and AI Content Checks
Scite: Scite checks source integrity rather than text overlap. Reference Check tells you if a cited publication was retracted, disputed or given an editorial notice. That protects academic integrity from a different angle.
QuillBot: The plagiarism checker scans a draft and highlights passages that match published text. An AI Humanizer also rewrites AI generated content to read more like a person wrote it.
The humanizer sits in the same menu and works on pasted drafts.
⚠️ Aviso: Rewording a source to dodge a detector is still plagiarism. Paraphrasing without a citation breaks most university rules, whatever tool produced the text.
7. Research Tracking and Dashboards
Scite: Custom dashboards let you track literature tied to your interests over time. Email alerts fire when a new citing paper appears, so you can see whether others found evidence that backs or disputes your work.
Journal rankings sit alongside the dashboards for judging where a publication lands.
QuillBot: There is nothing to track here. QuillBot has no alerts, no dashboards and no view of the wider literature. It only sees the document in front of it.
8. Patents, Funding and Publication Data
Scite: Patent search extends the index past journals into filed inventions. It is useful when a research paper has a commercial trail worth following.
Funding data shows which institutions back a given field.
QuillBot: None of this exists in QuillBot. If your thought process runs through funders, patents and journal quality, this is not the tool for that stage.
9. Integrations and File Handling
Scite: A browser extension shows how an article has been cited while you read it online. Scite badges also appear inside Google Scholar and PubMed. API access lets a lab pull the data into its own systems.
QuillBot: Extensions cover Chrome and other web browsers, plus MS Word and Google Docs. A PDF converter turns documents into editable text. QuillBot Flow adds a word processor where research, notes and citations sit together.
10. Preços e Custos
Vamos comparar os planos lado a lado.
| Plano | Scite | QuillBot |
|---|---|---|
| Livre | ❌ | $0 (Grátis para sempre) |
| Mensal | $20 | US$ 4,17 por mês |
| Anual | US$ 12/mês | US$ 4,17 por mês |
| Equipe | Institutional access | Preços personalizados |
Scite: You pay $20 monthly or $12/month on the yearly plan. There is no free version to fall back on. The cost only makes sense if you run a literature review often enough to use the index hard.
QuillBot: Premium sits at $4.17 per month, roughly a third of Scite’s yearly rate. The free tier also lets you test the paraphraser before paying anything.
💡 Dica profissional: These prices are close enough that many labs buy both. Scite finds and vets the papers, then QuillBot tidies the draft. Roughly $16 a month covers the pair.
Diferentes cenários
| Se você precisar | Escolher | Por que |
|---|---|---|
| Orçamento apertado | QuillBot | Free plan plus $4.17 Premium |
| Evidence behind a claim | Scite | Supporting or contrasting tags |
| Faster drafting | QuillBot | Seven writing modes |
| Reference vetting | Scite | Retraction and dispute flags |
| Ideal para iniciantes | QuillBot | Interface de usuário mais simples |
💰 Seu orçamento
QuillBot’s free version costs nothing and never expires. Scite has no free tier, so the cheapest way in is $12/month on the yearly plan.
🔌 Seu conjunto de tecnologias
Scite layers onto Google Scholar and PubMed, where you already search. QuillBot works inside Word, Docs and Chrome, where you already write.
📝 Seu processo de escrita
If your writing process stalls at gathering sources, Scite unblocks it. If it stalls at phrasing, QuillBot helps more.
🎓 Seu nível de experiência
QuillBot’s user friendly interface makes it easy on day one. Scite assumes you already know how to read a scientific article critically.
📚 Your Library Access
Scite indexes open access and paywalled content alike, but you still need rights to read the full text. Check what your institution already licenses first.
🛟 Opções de suporte
Both run email support and both draw refund complaints in reviews. Cancel through account settings rather than relying on a reply.

O que nossa avaliação não abordou
This comparison focused on individual students and small research groups. We did not test Scite’s API at scale or QuillBot’s Team Plan seats. Institutional licensing, custom billing and enterprise onboarding sit outside what we looked at. Our notes reflect the July 2026 versions of both tools, and features move quickly in this category.

🏆 WINNER: QUILLBOT
QuillBot wins 5 out of 7 categories.
Ideal para: Students writing papers, content creation, everyday editing
QuillBot and Scite are not really rivals. They handle different halves of the same job.
QuillBot takes the win because it does more for far less money. The free version alone beats paying $12/month for a tool you may open twice a term.
Scite is the stronger product inside its lane. Researchers running a serious literature review call it indispensable, and no writing assistant replicates what Smart Citations describe.
If you write more than you search, start with QuillBot. If you are three months into a thesis and drowning in references, buy Scite instead.

The video below sets QuillBot beside several of these ferramentas de IA in one pass.
Across those matchups the pattern holds. QuillBot makes the most sense when you want one cheap tool that covers the whole writing experience, and the premium version still costs less than most rivals charge. It also benefits users who mainly want to save time trimming an essay’s word count while keeping a personal touch in the prose. That mix is why QuillBot works as a default pick and why many readers rate it the best AI helper for coursework.
