Fabulator is a platform for playing and authoring interactive stories narrated by an AI game master. Pick a published World Seed and play it directly, or author your own using the Creator SDK and no-code world-building tools. Every turn is continuous narrated prose, not a chat log — the AI adapts the story to your choices while an underlying rules engine keeps outcomes fair and consistent.

Play

Fabulator's narrator and rules engine run on AI providers you choose and configure yourself (bring-your-own-key), not a single house model that Fabulator operates for everyone.

AI narration and your content

We use first-party, self-hosted metrics to understand aggregate usage of the app — we do not use any third-party analytics vendor.

Analytics

We use Cloudflare Turnstile in invisible mode on sign-up, sign-in, and password-reset forms to protect the service from automated abuse.

We collect the minimum information needed to run the app and keep your campaigns available across sessions.

Content you create or generate through play — campaigns, characters, World Seeds, and related metadata, including narration generated during your sessions.

Data we collect

We use your data to provide and improve the service, and to keep it secure.

How we use your data

We keep your data for as long as your account is active or as needed to provide the service, and for legitimate business or legal purposes.

Retention

Bring-your-own-key credentials are encrypted on your device before storage, and our servers never see the plaintext key. Beyond that, we use reasonable measures to protect your data, but no method of transmission or storage is completely secure.

Security

We do not sell your personal data. We may share limited information only in the situations below.

Sharing

This policy explains what Fabulator, operated by Mystery Digital Limited, collects, how it's used, and the choices you have when playing or authoring on the platform.

Overview

Depending on your location, you may have rights to access, export, or delete your data.
