How Nexus uses AI

We're a handful of developers who run tables together. Nexus uses AI. If that makes you wary, good. This page is for you. These are the lines we draw for ourselves and the record we expect to keep when they change.

The short version

You run the game. Nexus carries bookkeeping. AI appears in narrow places, such as drafting a name, finding a rule, or summarizing a session, only when you ask. Nothing enters your campaign unless you accept it, and the product remains useful with AI switched off.

Five commitments

The GM owns the story. AI suggestions are drafts to take, edit, or throw out. There is no automatic publishing and no auto-running your game.
We do not train models on your content. Not on campaigns, compendium content, or submitted artist-interest materials. Our providers process API requests under terms that prohibit training on that traffic.
Your campaign stays yours. AI receives only the context needed for the request you make. We improve product behavior from aggregate outcomes, not by reading your campaign writing.
AI costs are visible. Usage is measured in the product. During the closed beta, shared allowance use is observed without surprise charges or top-ups.
AI can be off. Campaign-level switches govern text, image, and transcription features. Compendium, maps, campaign management, and live play continue without an AI request.

Tools are not creators

A tool that finds a rule or drafts a recap leaves creative decisions with a person. We do not want an AI game master, AI players, or a substitute for the person behind the screen.

We do not sell AI-generated art. Our compendium uses original writing and openly licensed material, with attribution shown where it appears. Books we do not have the right to use are not fed into a model or reproduced in the product.

Human art has a different boundary

Public compendium placeholder images that are AI-generated remain visibly disclosed. They may only be superseded through approved human-art controls; a generated image is never silently presented as a human-made commission.

Artists can tell us how they want to participate in the Artist Network interest intake. That intake is not an account, commission offer, license, or request for artwork. It does not grant us training, reference, publication, or other rights in an artist's work. Invited beta artists can keep portfolio pieces, drafts, experiments, references, and works in progress private in Studio unless they later approve an exact controlled public derivative.

Artist Network interest intake

Why use AI at all?

Some narrow uses help people stay in the game. A running recap lets a table pick up the thread after a missed week. Transcription helps when speech moves faster than attention. Rules lookup keeps play moving. None of that replaces a creator. It clears the path back to the table.

We use the smallest practical model, retrieve instead of regenerate, and cache aggressively. If you want zero AI, the master switch gives you zero and the rest of the product still works.

Questions we expect

Did you scrape sourcebooks? No. The compendium is original writing and openly licensed material. Full attributions are on our Legal and Licenses page.

What leaves my campaign for AI? Only the content needed for the request you invoke, sent to a provider for that request. See the Privacy Policy for processors and rights.

Do you learn from my campaign? From aggregate signals about whether a suggestion helped, not from campaign content. Any study of real content would require a separate, explicit opt-in.

What about environmental cost? It is real. We do inference only when requested, use the smallest practical model, cache aggressively, and keep a useful AI-off product instead of treating offsets as an answer.

Will this page change quietly? No. Every substantive change gets a dated entry below.
