Frequently Asked Questions

Have another question? Contact us at [email protected]

How accurate is citation verification? How do you ensure these aren't AI-fabricated?

We don't rely on LLMs to blindly generate results. Instead, we cross-reference your input against PubMed, CrossRef, OpenAlex, Semantic Scholar and other authoritative databases in seconds. Our core algorithm locates and highlights real supporting sentences, eliminating AI hallucinations at the source.

Is my research data and drafts safe on LitSource?

Academic privacy is paramount. LitSource uses end-to-end encrypted transmission (SSL/TLS) to protect your data. Your unpublished drafts, outlines, and search history are never used to train any external public models. You retain full intellectual property rights.

Which databases does LitSource cover? How often is data updated?

We integrate major global databases, covering 100M+ biomedical and life science papers, PMC, CrossRef, and more. Data syncs daily, ensuring the latest publications and Online First research are available for immediate search and verification.

Does it support non-English claims?

Yes. With our built-in bilingual cross-referencing model, you can input claims in Chinese or other languages. The system automatically converts them into precise English search queries to retrieve global literature.

Which reference management tools are compatible?

Export verified references directly to EndNote, Zotero, Mendeley and other major tools, or export in standard BibTeX and RIS formats. We also provide APA, MLA, Harvard, Vancouver, and other standard citation styles.

How are credits used? Am I charged for failed searches?

Each successful literature search costs 1 credit. Citation verification costs 3 credits for each batch of up to 10 references. Search credits are not deducted when no qualifying results are found.

Is there a free tier? How do I get more credits?

The Free plan includes 10 credits per month. Higher-volume users can choose a monthly or annual Pro plan, or purchase the one-time Trial Plan with 300 credits and Pro access for 30 days.
