What is an AI game master (AI DM)? Can it replace a human host?

In most tabletop games the exhausting seat is the host (DM, Keeper, Storyteller): prep the script, voice every NPC, adjudicate rules, guard the secret. An AI game master hands that seat to an AI.

What an AI host does

It generates the plot and cases live, plays lying and scheming NPCs, resolves dice and checks by deterministic rules, and strictly guards the truth only the host should know. It never speaks for the real players — you and your friends are the table.

Can it replace a human?

For the common case — can't gather enough people, nobody wants to DM, you want to start on demand — an AI host is close to essential, while it keeps closing the gap on a human host's live chemistry. Pick a mode and try it.
