The demo has three complete claim records. The full product has all 15, with their sources, limitations and recorded revisions. Every claim is AI reviewed; none has independent scholarly review. This is a small, uneven pilot, with modern reference locations rather than a reconstruction of the past.
Why I'm building this, and how I use AI
I want it to be easier to find out what we know about the past and why we think we know it. When people start from very different versions of reality, it becomes harder to understand and trust each other.
I've put a lot of care into the research pipeline and its evidence standards. I use AI for the parts I don't have time to do manually. The process is designed to keep sources, check what they support, distinguish evidence from inference, preserve uncertainty and make claims possible to reassess.
The ambition is to keep raising that standard and apply it consistently across a much broader history than any one source covers. That is a direction for the work, and something the results still have to earn. Corrections can mean changing a claim, researching it again or changing the process that produced it.
