FAQ

Frequently asked questions

What types of sources can I find?

Our platform helps you discover a wide range of primary and secondary sources including historical documents, academic papers, and government records. We provide detailed information about these sources, including where they're housed and, when available, links to digital repositories where you might access them.

Can I access the original documents through Primary Source Finder?

Primary Source Finder helps you discover which sources exist and why they matter, but doesn't house the original documents themselves. For many sources, we provide links to digital repositories where the documents may be available. For physical archives, we provide information about where the sources are housed to guide your further research.

How accurate is the AI research assistant?

Sofia is designed to help you reason about sources, but like any AI it can make mistakes. We recommend verifying important conclusions against the sources themselves, and we improve quality continuously based on feedback.

Can I export my research findings?

You can save key takeaways and source notes as you work. Export options are evolving during beta as we learn what formats users need most.

Is there a limit to the number of searches?

Limits can apply depending on your plan and where you are in the beta. Our goal is to keep access affordable while managing compute costs.

How do you ensure source authenticity?

We prioritize reputable repositories and include source metadata when available. Because sources can vary in quality online, we encourage users to cross-check provenance (who created it, where it came from, and how it has been preserved) before relying on it.
