I had a couple of followups to my blog post from last night, so here is a quick update to that post.

Dave Flanagan has created a plugin to Simon Willisons llm tool that checks references from LLMs against Crossref https://github.com/DWFlanagan/llm-citation-verifier

Chris Reid pointed me towards https://www.undermind.ai/ and https://platform.futurehouse.org/, both of which follow an approach that I outlined yesterday. 

For bonus points Futurehouse helpfully tells me if a references is "peer reviewed ", a "clinical trial", "domain leading", or "highest quality".
