So I'm very sceptical about AI in general so I appreciate that this isn't a product aimed at me, but I'd figured I'd engage a bit.
My main question is... What do you think the main value add for the AI is? The main one I can see is being able to generate lore quickly, and then manually tweaking it to your liking. But you could use a general purpose genAI to do that.
For managing character sheets, you have the problem of accuracy. GenAI chatbots are just bullshitting machines and are programmed to be convincing, not correct. How are you going to prevent your chatbot from saying wrong things? How are you going to get players to trust it?
Most rules conflicts in ttrpgs are due to people having different interpretations of the rules. Is your bot going to be just another voice in the argument as to whether you can split a jump over two turns?
What advantage does a chatbot bring over a dedicated system specific wizard? Sure they need specifically programmed for each new system, but then they work perfectly and can display fancy user interfaces.
Since you are using genAI, how ethically and legally sourced is your training data? Are things we type going to be used to train the bot? You have a summary feature to summarise sessions, how does that work if players use voice chat to run their games? Will voice chat we use when interacting with the platform be recorded?
A fun little challenging question you need to figure out sooner rather than later: Will NSFW stuff such as porn and bdsm be allowed in the platform? :P
And a more practical question: How much does the subscription cost? If it's "free", what's your monetisation strategy?
Lastly... Stop throwing the word "proprietary" around so much. It comes across as super clingy.
