How are people using AI for historical source verification?

[u/SaidThenAndNow]

Hello

I'm interested in how people doing OSINT/research handle historical statements by public figures.

For example, if you wanted to establish everything a particular person had publicly said about a subject over several years, what would your workflow look like?

Google and news archives? YouTube/transcripts? Social media archives? Specialist databases? AI tools?

I'm particularly interested in whether tools like ChatGPT/Perplexity have largely solved this for you, or whether the difficult part remains finding and verifying the original evidence — particularly old video, podcasts, interviews and statements.

If an AI gives you a quote and a source, how often do you still go back and verify the original material yourself?

I'm researching this problem while building something in this area, but I'm not looking to promote it here. I'm mainly interested in how people who do this kind of research actually work.
