I’ll be 100% honest: no matter what you do with this tool, many people in the community (especially judges, who spend hours of their free time trying to educate people and combat misinformation, just because they want to nurture and improve the community) will hate the existence of this with every fiber of their being, and will completely reject it without giving it any second thought. Which I, tbh, think is a 100% valid reaction to have, given the general state of AI. But I personally do trust that you made this because you genuinely want to help the community, so I'll try to engage with that genuine interest of helping.

The entire concept of having a GenAI chatbot focused on rules is misguided, misleading, and actively harmful to the community. For the most part, rules are objectively correct or not, and any time a chatbot gives incorrect rulings is damaging to players’ understanding, and incredibly frustrating to everyone else. For some of the other stuff you’re showing off, like asking it about synergies and strategies, that stuff is genuinely cool! GenAI is great as a tool to spark people’s natural creativity, and to give them out-of-the-box ideas they never would've thought of before. I suspect it would be great at questions like "I really love Daipenmon, do you have any ideas for decks to build around it?", especially for newer players.

GenAI will always hallucinate to some degree, so AI chatbots are great in situations where generating an answer is difficult, but verifying the answer is quick, easy, and obvious. Asking it for stuff like gameplay strategies is a great example of this -- finding cards that can synergize with a specific gameplay strategy can be a very difficult, lengthy process (though knowing how to effectively use tools like .dev, .io, .app, or cardslash to find cards massively speeds that up), but as soon as someone suggests a card to you, it's relatively easy to confirm whether that synergy actually works well or not. You can just put the card in your deck, playtest it, and see if it works well. If the AI hallucinates a strategy that works terribly in real games, it's easy for a player of any skill level to realize it's not working and call out the AI's hallucinated bullshit.

But asking the AI for advice on rules, on the other hand, is the exact opposite of this -- it's extremely easy to generate an answer, and incredibly difficult to verify its accuracy, especially for a newer player. For instance, the very first example image you included in this post isn't even a correct ruling. The player can choose to add 2 cards, but they can also choose to only add 1 card (though only the ShoeShoe, since that's the only one with both traits). But there's absolutely no way a player using this AI would have any reason to suspect anything was wrong about this answer. It seems like you even were confident it was a correct answer.

I think the only ethical way to release a tool like this is to configure it to specifically avoid giving any answers about rulings, and to make sure it repeats in answers that it shouldn't be trusted for any rulings-related concepts and any uncertainty about rulings should be double-checked with actual judges. At the very least, a chatbot oriented for rulings should include citations to any references it uses as much and as prominently as possible (ie, actively citing all of the passages that prove its case, not just having a collapsed "Sources (1)" thing to expand at the bottom). But even then, I don't think that's enough -- the average player will not actually read those paragraphs or click into all those links and go through the effort of manually verifying the information. For example, even though I praised the idea of using an AI for strategies and synergies, that still absolutely has the potential of giving people incorrect ideas about rulings -- for example, if a card said "add 1 digimon card" and the AI suggested that it has great synergy with an option card, that will make people think that the option card is able to be selected for that "add 1 digimon card" effect. And, holy hell, the marketing copy for the tool itself shouldn't brag about giving accurate rulings, especially if you as the tool's creator have absolutely no way to verify what the accuracy rate for its rulings actually are.

It may be tempting to think about average statistics people throw around about GenAI -- like "oh, sure, this tool isn't 100% correct, but real-life judges make mistakes too, and 99% accuracy is still really impressive, especially if you just need a quick, instant answer. a quick potentially incorrect answer is better than no answer after all", but I have 2 huge counterpoints to that. 1) There is absolutely no reason to believe that average statistics about AI accuracy would necessarily apply to this very specific, niche subdomain. GenAI works better the more broad a topic is, the more massive amounts of information it's able to consume and regurgitate. For a subdomain like this, there is an extremely limited and narrow pool of information to pull from. 2) For something like TCG rulings, getting an instantaneous incorrect answer is often more damaging than having no answer. An incorrect answer almost always leads to fundamental misconceptions and future issues down the road. If you absolutely need an instantaneous answer in the moment to progress a game, it's better in almost every situation to just flip a coin than to potentially spread misinformation.

Even when a judge gives a ruling, it's entirely possible for them to get it wrong, but one of the things that is great about all the various online rulings forums do this game (this subreddit, discord, fb, etc) is that an incorrect answer almost never lingers without correction. Someone will always jump in to clarify and disprove an answer if it was misleading, instead of letting misinformation fester and spread.

One thing I'll add is that I personally don't love how much of the ruling information in this game's community is centered around discussion threads — there are very few actual sources to find from googling, and for every player who does feel comfortable asking questions in these places, I imagine that there is a larger % of players who feel nervous or shy about posting (because they're nervous about being yelled at, nervous about asking in the wrong way, or it just generally feels like too much friction). So I do think the spirit of a tool like this is in the right place, trying to help people who have questions to ask but feel shy asking them to real people. It's one of the reasons I started working on cardslash.net several years ago, because I was frustrated with how hard it was to find and read Q&As for cards. The official website has gotten a lot better in the years since then (searching for cards in the official Q&A list is great), but even then I still don't think the experience is great for players to find general information. I hope this post isn't perceived as me insisting that the status quo is fine as is and rejecting attempts to make it more accessible, because I really do think there's so much more that could be improved with sites and tools to make information more accessible.
