Horror one-shots for ChatGPT, Claude & Gemini
Solo dread one-shots that commit to the scare instead of chickening out — one shift, one night, no one coming. Free, no signup — each game is a card you load into your own AI assistant.
An AI horror one-shot is a single-session scare the assistant narrates while a card holds it to the consequences. The card fixes what the threat does and when, so the game commits to an ending instead of retreating from it once you are in trouble.

Making an assistant commit to the scare
Assistants are agreeable, and agreeable is the enemy of horror. Left to improvise, the thing in the dark stays a rumour: the danger is described, then quietly withdrawn the moment it would actually cost you something. You end up reading atmosphere rather than surviving anything.
These are one-shots with a fixed shape — one shift, one night, nobody coming. The card specifies what the threat does on a schedule, what your choices spend, and what is unrecoverable, so the escalation happens whether or not you engage with it. Vigil runs on a published dice tape, so its bad nights are dealt rather than authored in response to how you are doing.
Both cards are rated 16+ and are built for solo play in one sitting, 45 to 90 minutes. They are dread rather than gore, and the fear comes from the schedule being indifferent to you.
Questions about horror one-shots
Will the AI actually let something bad happen?
That is the specific problem the card solves. The threat's behaviour is written into the card on a schedule rather than left to the assistant's judgement, so an outcome you have earned is not quietly withdrawn for being unpleasant. Vigil goes further and takes its rolls from a published tape, so a bad night is dealt from a fixed sequence rather than chosen in the moment.
How intense are these, and can I set limits?
Both are rated 16+ and aim at dread and isolation rather than gore. You can tell the assistant at the start which subjects to keep off the table and it will route around them; the cards are written so the pressure comes from the schedule and the setting, not from any one image, so avoiding a topic does not defuse the game.
Do I need to finish in one sitting?
They are designed as one-shots of 45 to 90 minutes, which is the shape the dread is tuned for. If you have to stop, ask for a save and resume from the plain-text block later — Vigil's save carries its tape position, so the night picks up on the same roll it would have reached.
