How the Narrator works

The dice are honest.
So is this page.

Markbound uses an AI model to write your Narrator's prose — and that's all it does. Below is exactly what the AI touches, what it never gets to decide, and what leaves your device. Plain language, no fine print.

The one promise

The AI never decides what happens in your saga. It only describes what your dice, your oracles and your choices already decided.

The Narrator's job

What it does — and what it never touches

Think of the AI as a writer sitting beside you, not a referee. It turns the table's results into story — it doesn't get a vote on them.

What the Narrator does

Writes the prose of each scene from your sheet, your dice and your journal.
Keeps the story coherent across sessions by reading recent entries.
Responds to the action or message you choose — and waits for your next move.

What the Narrator never does

Roll dice — every roll is crypto-grade randomness, in your browser.
Draw oracles — those are plain table lookups on your device.
Silently change your sheet, vows, momentum or tracks — every change is one you can see in the journal.

Your data

What leaves your device — and what never does

Each time you ask for a Narrator turn, we send the model just enough to write the next scene well. Nothing about your account goes with it.

Sent for each turn

The instructions that define the Narrator's role and limits.
A condensed slice of your sheet — stats, conditions, vows, assets.
A recent slice of your journal, so the story stays coherent.
The Living Codex and narrator memory needed for continuity, including known NPCs, locations, consequences, clues and inferred play-style signals.
The dice and oracle results the Narrator has to respect.
Your latest message or chosen action.

Never sent

Your email address or password.
Your billing or payment details.
Any other account's characters, sagas or journals.
Anything we don't need to write the next scene.

What you can count on

Three things that won't change

We never train on your sagas

Your characters, sagas and journals are never used to train any model — ours or anyone else's. We don't sell your content. Ever.

It's fiction, not facts

Narrator output is a story. It can be wrong, contradictory or odd. Treat it as a creative collaborator, never as factual advice.

The AI is opt-in, always

Dice, oracles, your sheet, the journal and PDF export all work with no AI in the loop. You call the Narrator only when you want to.

Under the hood

Which models we use

Narrator and summarizer turns are currently routed to the Kimi K3 model, accessed directly through Moonshot AI's API. Lovable Cloud still supports parts of the app infrastructure, but it is not the current production narrator gateway.

Prompts run under the provider's API terms. Providers may briefly retain prompts for abuse monitoring. Markbound does not train on your sagas, sell your content, or use your journal text outside the narration features. If we add a standing fallback model from another provider, it'll be named right here.

EU AI Act — Article 50

Transparency, stated for the record

The EU AI Act's transparency obligations apply from 2 August 2026. Markbound is a creative-writing tool, not a high-risk system, but the disclosure duties are simple and we meet them plainly:

You are interacting with an AI system. The Narrator is a large language model, never a human game master, and it is labelled as such wherever it writes.
Narration is AI-generated content. Every Narrator turn in your journal — and in any export — is machine-generated fiction, not a factual record and not human-authored text.
No emotion recognition, no biometrics, no profiling. We do not infer emotions, identity or personal characteristics about you from anything you write.
No deepfakes of real people. The Narrator writes original fiction about your characters; it does not generate audio, video, or imagery depicting real persons.
Human oversight is yours. The AI can be switched off entirely — dice, oracles, sheet, journal and export all work without it — and every rules outcome is decided by your dice, not the model.
