Compare literature search, evidence extraction and citation checks
For a literature review, start with one question and a small set of papers you know. Compare what the tools discover, extract and cite, then trace one finding back to the original paper.
Scroll the table sideways for all limits and official sources.
| Your task | Tool | Why consider it | Conditions and source |
|---|---|---|---|
| Discover scholarly papers | Consensus | Find studies for a focused question and use plan-dependent synthesis features. | Paper discovery and advanced analysis have different limits. Read the underlying studies.Official source |
| Screen papers and extract evidence | Elicit | Organize literature-review evidence into structured fields. | Check screening and export access, and verify extracted values against the paper.Official source |
| Inspect citation context | Scite | Investigate how later work discusses a finding, including supporting and contrasting citations. | Citation labels assist reading; they do not replace judging the study design or conclusion.Official source |
| Web research with source links | Perplexity | Research mode investigates a question across web sources and prepares a sourced response. | Free users have limited Research access. Open the sources and check their dates and relevance.Official source |
| A multi-step research report | Gemini | Deep Research uses web search and can work with added files or connected sources. | Source access and usage limits depend on the account. Review the research plan and original evidence.Official source |
| Understand your own documents | Claude | Ask questions about supported uploaded documents and compare passages with a focused brief. | File type, size and account limits apply. Verify quoted passages against the original file.Official source |
| Find an initial paper by title or author | Semantic Scholar | Search for a known paper or topic, then open the paper record and inspect references and citations. | Database coverage and full-text access vary. Open the publisher record to check the paper before citing it.Official source |
| Explore citations from papers you already trust | ResearchRabbit | Start with one or more seed papers and use the citation graph to discover earlier work and related publications. | The graph depends on your starting papers. Use a separate keyword search if you need broader coverage.Official source |
- Choose paper discovery, evidence extraction or citation checks first; use web and document tools for the material those tasks require.
- Set the question, date range and sources you need before starting a report.
- Check file permissions, connected-source access and the actual plan allowance.
- Distinguish a web citation, a paper abstract and full-text evidence.
- Open important sources and check the precise passage supporting each claim.

Questions before you choose
Is AI research only for academic papers?
No. Web research, reports on your own files and scholarly literature reviews are different tasks. Choose a tool with access to the material your question needs.
Do citations guarantee an accurate report?
No. Open the source and check its date, methods and the passage supporting the claim. A correct link can still be used for the wrong conclusion.
Are all research modes free?
No. Search, multi-step reports, file uploads, extraction and export can have separate limits. Use the checked-free filter, then confirm the exact feature at its official source.
