Key Benefits of Elicit AI
Here is what makes Elicit AI worth a look:
- Semantic search: It reads the intent behind your question. You do not need a perfect keyword match to surface relevant papers.
- Paper screening: It checks thousands of academic papers against your inclusion and exclusion rules. Each decision comes with a short rationale.
- Extrator de dados: It pulls sample size, methodology, and other key information into one table. Custom columns let you add your own fields.
- Elicit Reports: This runs a rapid review on your topic. It can draft literature reviews of ten pages or more.
- Sentence-level citations: Every claim links to a specific sentence in the source paper. That cuts down on made-up references.
- Works with citation managers: You can import and export libraries with Zotero and EndNote.
- Gap finding: It flags thin spots in the evidence. That helps you shape future study plans.
The panel below shows those benefits inside the app.

Teste grátis: A free plan is available, and a trial of the paid tools is offered before you commit.
Garantia de reembolso: No published refund window. Start on the free tier first.
📌 Observação: Every listed price is the annual rate shown per month. Month-to-month billing usually costs more, so check the plan page before you pick a tier.

Comparação de recursos
Now for the side-by-side view. We look at nine areas plus cost, so you can see where each ai tool pulls ahead.
| Recurso | Solicitar IA | Guia de papel |
|---|---|---|
| Preço inicial | $0 free, paid from $9 | $0 free, paid from $12 |
| Plano Gratuito | ✅ | ✅ |
| Semantic paper search | ✅ | ✅ |
| Screening with rationale | ✅ | ❌ |
| Data extraction tables | ✅ | ✅ |
| Bate-papo com PDF | ❌ | ✅ |
| AI writer for drafts | ❌ | ✅ |
| Built-in reference manager | ❌ | ✅ |
| Verificador de plágio | ❌ | ✅ |
| Extensão do Chrome | ❌ | ✅ |
| Ideal para | Systematic reviews | Research plus writing |
1. Literature Search and Paper Discovery
Solicitar IA: The Paper Researcher reads the meaning behind your query instead of matching strings. That means you can find relevant papers without guessing the exact wording an author used. It also suggests search terms and alternate questions when your first attempt comes back thin.
Guia em papel: Its ai search pulls from academic databases including Semantic Scholar. Results arrive with short summaries so you can judge fit before you open a paper. The searching features cover fewer filters than a dedicated review tool.
2. Data Extraction and Research Tables
Solicitar IA: The Data Extractor can pull sample size, methodology, and outcomes from hundreds of papers at once. Everything lands in one table you can sort and export. This is the fastest way we found to extract key information at volume.
Guia em papel: You can extract data from uploaded documents, including values inside tables. The output is useful, but batch sizes stay smaller. It fits a shortlist of twenty papers better than a screening run of two thousand.
⚠️ Aviso: Always spot-check extracted numbers against the source. Both tools read tables well, but neither replaces a second pair of eyes.
3. Literature Review Workflow
Solicitar IA: The Notebook keeps your question, your criteria, and your matrix in one thread. It screens academic papers against inclusion and exclusion rules and explains each call. That structure suits the literature review process for systematic work.
Guia em papel: Its literature review module gathers sources and drafts a narrative around them. It moves faster from reading to first draft. It gives you less auditoria trail if a supervisor asks how a paper got included.
4. Reading Papers and Chat
Solicitar IA: Topic Finder maps a field before you commit to reading. You can filter an abstract summary by intervention, outcomes, and population. There is no free-form chat window, so answering questions happens through structured columns instead.
Guia em papel: Chat with PDF is the headline here. Upload papers, then ask paper specific questions and get key points with citations back. For casual users and complex topics, this is the friendlier route to deeper insights.
5. Automated Research Reports
Solicitar IA: Elicit Reports runs a rapid review end to end and returns ten pages or more. Custom columns let you decide which fields the report tracks. Sentence-level citations keep every claim linked to a real source.
Guia em papel: Deep research reports gather multiple sources and write a structured brief. The result reads more like a narrative essay than an evidence matrix.
O relatório construtor also lets you set the depth and length before it runs.
6. Citations and Reference Management
Solicitar IA: It does not try to replace traditional reference managers. Instead it exports straight into Zotero and EndNote, so your existing library stays the single home for references. If you already run one of those citation managers, that is the cleaner setup.
Guia em papel: It ships its own reference manager with folders, tags, and support for several file formats. Papers you cite while drafting get added on the spot.
A separate generator handles one-off citations when you only need a formatted entry.
7. Academic Writing and Drafting
Solicitar IA: There is no writing assistant here. It gives you evidence, ideas, and structure, then hands the writing process back to you. For some supervisors that separation is a feature rather than a gap.
Guia em papel: Full document generation drafts entire sections from your sources. The ai writer keeps your cited papers attached as you build out academic writing. You still edit heavily, but the blank page problem goes away.
⚠️ Aviso: Many universities restrict ai powered research drafting. Check your department policy before you submit generated words as your own.
8. Plagiarism and Research Integrity
Solicitar IA: No plagiarism tool is included. Its integrity angle is different: sentence-level citations tie each statement to a source, which limits invented claims. Medical and clinical teams lean on that when they process papers for evidence reviews.
Guia em papel: A plagiarism checker is built in, which matters when the same app also drafts your texto. Running the check before export is a sensible habit.
9. Ease of Use and Everyday Workflow
Solicitar IA: The layout is plain and needs little training. Research alerts watch your topic and flag new papers by date, so you can automate research workflows like ongoing monitoring. Other research tasks such as brainstorming research questions sit in the same panel.
Guia em papel: The user friendly interface groups reading, citing, and writing in one sidebar. Fewer tabs mean fewer handoffs across the day. The trade-off is that its powerful features sit behind a busier screen.
10. Preços e Custos
Here are the published plans side by side.
| Nível | Solicitar IA | Guia de papel |
|---|---|---|
| Livre | Basic (Free): $0 | Free $0/per month, billed annually |
| Entrada paga | Basic: $9 | Plus $12/per month, billed annually |
| Meio | Standard: $12 | Pro $24/per month, billed annually |
| Superior | Pro: $19 | — |
| Personalizado | Empresa: Contate o departamento de vendas | Enterprise Custom Plan |
Solicitar IA: Four steps between free and Enterprise give you room to grow slowly. The $9 entry tier is the cheapest paid option in this matchup. What you buy at each step is mainly extraction volume, not new modules.
Guia em papel: Plus costs $3 more than the Elicit AI entry plan, and Pro doubles that again. In return you get a writing suite, a reference manager, and the plagiarism check in one bill. If you would otherwise pay for two apps, the maths can still favour it.
💡 Cost tip: Both list a free plan. Run the same research questions through each for a week before you pay anything.

O que nossa avaliação não abordou
This comparison focused on individual students, academics, and small labs. We did not test institutional licences, single sign-on, or API access for either product. Paperguide carries no rating in our data set yet, so its scorecard entries rest on documentation rather than a scored review. Non-English literature and discipline-specific databases outside Semantic Scholar and PubMed also sit outside what we checked.

🏆 WINNER: ELICIT AI
Elicit AI wins 4 out of 7 categories.
Ideal para: Systematic reviews, batch data extraction, evidence-first research workflows
These two tools overlap less than the category name suggests. Elicit AI is a research assistant for finding and judging evidence. Paperguide is a research and writing workspace built around the finished document.
Paperguide is the better buy if your bottleneck is drafting, citing, and keeping references tidy. It replaces two or three apps, and that alone can justify the higher tier.
For most academic work, though, the harder problem is deciding what to read and what to trust. Elicit AI answers that better, costs less to start, and leaves your reference setup alone.
