Cthulhu Investigation (CoC)
An online Call of Cthulhu horror case, hosted by an AI Keeper
In Cthulhu Investigation mode the AI plays the Keeper and runs a cosmic-horror case with sanity, real dice checks and layered clues, generating scene art on the fly.
How it plays
- 01Build your investigator: stats, occupation, skills
- 02Investigate the scene; actions trigger real skill rolls and dice
- 03Sanity drains through horror; combine multiple clues to deduce
- 04The world reacts to what you do and never spoon-feeds the answer
Why it is good
It is a genuine ruleset, not freeform chat — dice, suspicion and clue resolution happen server-side, so the AI narrates but cannot cheat or spoil the truth.
