Thanks for checking out **RailMystery**.

**What it is:** a cloud Host for short AI murder-mystery nights. You buy one Host seat, open a browser room, share a code — guests join free on their phones (no app). Private clues on mobile; Host runs the terminal.

**Why we built it:** freeform AI hosts sometimes rewrite the culprit mid-session. Ours is locked to a **fixed story rail** (legal edges only) so the mystery stays fair and solvable.

**Debut pack:** *Midnight Ferry* — original English short, commercial-safe (no fan IP).

**Early seats (one-time):** $7 Early Host · $12 Launch Pack · $15 Founding Host — guests never pay.

Happy to answer Host / session questions in the comments. Honest “wouldn’t buy because ___” helps too.
