• Focus on biomedical field

Choose Elicit/Consensus if you:

• Are still in exploratory research phase (don't know what to write)
• Need to quickly understand research status in a field
• Cross-domain research (not limited to biomedicine)

Choose Semantic Scholar if you:

• Have budget constraints (completely free)
• Prefer traditional keyword search

Common Questions

Q1: What's the difference between LitSource and LitSense?

LitSource is an independent reverse citation search tool with two core capabilities:

1. Reverse Search: Input claim → AI semantic matching → Highlighted evidence sentences → One-click citation export (this is the core "claim-to-evidence" workflow)
2. Reference Verification (Verify): Paste reference list → Auto-validate DOI authenticity → Compare metadata consistency → Identify "real/suspicious/fake" citations (This is LitSource's unique feature that can prevent AI-generated fake references from entering your paper)

Additionally, LitSource provides:

• Sentence-level evidence highlighting (not abstract summaries)
• Multi-dimensional filtering (by section, year, journal impact factor, citation heat)
• Biomedical entity recognition (genes, diseases, drugs, etc.)
• Full-format citation export (including Chinese GB/T 7714)

If you're looking for "alternatives to LitSense," LitSource is a more comprehensive choice.

Q2: Will these tools fabricate papers (AI hallucination)?

• LitSource/Semantic Scholar: No, they return real papers with PubMed/DOI links
• Elicit/Consensus: Mainly summarize real papers, but AI summaries may have bias; recommend verifying original text

Q3: Which tool supports Chinese literature?

Currently these tools mainly search English literature. LitSource supports Chinese claim input (will translate and match English papers).
