Whatever you do, please please please ignore “5. Keep Track of the Game State”.
ChatGPT has a horribly short attention span. It will forget important details long before you reach an amount of notes where you would actually need an assistant. Here’s a source from the same website as the article that lists ChatGPT’s limit as 4096 tokens which is usually less than 1500 words. For reference, the Wikipedia synopsis for Critical Role Campaign One which is a lot less detailed than what you would need as a knowledge base has 760 words. Just adding the episode summaries from the same page would exceed ChatGPTs token limit by a lot.
If you’re a paying customer, you have access to the 32768 token version of GPT-4 but that’s still not a lot. About 10000 words. And the worst thing is that you might not even notice when it starts hallucinating incorrect details because it forgets older context. I also wouldn’t rely on OpenAI keeping old conversations accessible for more than a few months.
Do yourself a favor and keep your campaign notes in a proper knowledge base. The cheapest solution is just a pile of text documents in a good folder structure. My personal favorite is a personal Wiki. MediaWiki, the software Wikipedia is running on, is literally free and open source software and can run on just about any cheap webhost or even directly on your pc. There’s also specialized stuff like Campfire or World Anvil which may or may not be overkill for your needs.
Pssh. As often as my players are actually around to play, I doubt anybody would notice if my AI assistant started making shit up.
Edit: I’ll also recommend my personal favorite note taker: Obsidian. It uses markdown and it’s also a wiki that supports tags so it’s super easy to use quickly.
