Campaign Studio by CharGen

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.
