Frequently Asked Questions

How are queries counted?

Each submission of a question or hypothesis counts as one query. Anonymous users get 2 queries per 7-day window. Registered users get 5 queries every 72 hours.

Can I query multiple databases?

Yes! Each database is independent. You can query any active database within your rate limit. Queries count globally, not per-database.

What's the difference between Standard and Hypothesis mode?

Standard mode answers your question with evidence from the literature. Hypothesis mode evaluates your hypothesis against the published evidence, identifying supporting findings, contradictions, and gaps, then delivers a structured verdict.

How accurate are the citations?

Citations are sourced from verified bibliographic metadata. Each citation links to a real paper with DOI, authors, journal, and year. The system retrieves from actual paper text, not generated content.
