Campaign Studio by CharGen - The campaign co-writer that can say "we do not know"

A writing room for tabletop GMs: campaign notes, session records, worldbuilding and an AI assistant in one place. It drafts, you decide. Nothing lands in your canon until you choose Insert, Replace or Apply. Answers cite your own notes, carry Known, Inferred or Proposed labels, and when the campaign genuinely does not answer something, the assistant says "we do not know" instead of inventing lore. Transparent gold pricing per run, and free accounts can try it.

Hi Product Hunt, I'm Nikita. I build CharGen on my own, and Campaign Studio is the piece I always wanted for my table: one writing room where my campaign notes, session records and worldbuilding live together, with an assistant that behaves itself. The design rule that took longest to get right: the AI never touches canon uninvited. It proposes; I choose Insert, Replace or Apply. Answers cite my own notes and are labelled Known, Inferred or Proposed, and when the campaign genuinely doesn't answer something, it says "we do not know" instead of inventing lore. If you've ever had a tool confidently rewrite your setting, you know why. Pricing is transparent: runs cost gold (1 for standard, 3 campaign-wide, 5 for Deep Prep), shown before you run anything. Free accounts can try it. I'd genuinely value feedback from GMs, especially where the assistant should refuse to guess and currently doesn't. I'll be here all day.
