I'm not super into Data Science or ML side of things but if we had the data information, I could get this ready within a week or two max. Lot of readily available frameworks that provide plug-and-play interfaces for such bots.
Tell me about it... I've spent the last couple days watching youtube videos on the various AI tools available. It's hard to focus on one because new systems are coming out almost daily now. I saw a nice open source one that is meant to automatically scan the website and build an LLM off of it. It would need tweaking, since it cannot parse all off bct and will need historical training - but once it's up to date, the forum provides new posts to guests very easily, and the search engine can be just like Grok.

I'm not going to do any coding because by the time I learn how to do something, I discover there is an AI bot that will do it in seconds. :/ In fact, I'm pulling away from most parsing projects to instead focus on things I enjoy. I can be an idea guy if you ever need a different perspective of something.
I assume you have resources available for development? Most cloud companie give free trials. If it launches and is popular, you'll obviously need to charge per search, or have it forum sponsored.
