AI Transparency Index: Every AI Disclosure on Steam, Tracked and Searchable

We are utilising ElevenLabs’ text-to-speech tool, to generate some voice-over elements within Train Sim World 7. This is utilised in features such as training modules, as well as platform and onboard train announcements. All scripts and content are written by Dovetail Games staff, with ElevenLabs used to generate the audio in these instances.

3D models for props and buildings have been generated with code developed by AI. The game splash screens and logo have been generated by AI. Music is generated live with code developed by AI.

Background music and placeholder images

Some shipped visual assets, narrative text, localization, and store or marketing artwork were created or iterated with the assistance of generative AI tools. All output was selected, edited, reviewed, integrated, and tested by the developer. The game performs no live AI generation and sends no player input or data to an AI service.

This game does not generate or modify content at runtime. A small portion of assets (around 20%) was made with the help of some generative AI tools during development. All such assets were manually edited, reviewed, and finalized to ensure originality, quality, and compliance with copyright and safety standards.

Some BGM are AI-generated. Additionally, some textures were AI-generated based on human designs and fully refined by hand. AI tools were also used for translation and general development assistance.

The game uses AI for procedural dungeon generation, gameplay management, and realistic enemy behavior simulation.

Some store page artwork was created with the assistance of generative AI and manually reviewed and edited. All in-game content and gameplay systems are made by the developer.

Pre-generated generative AI tools were used during development to assist in creating and editing some 2D visual assets, including backgrounds, character images, scene variations, and promotional artwork. AI tools were also used to assist with drafting, editing, and localization of some text. All final content was selected, reviewed, and edited by the developer before inclusion. No generative AI is used during gameplay, and players cannot generate content in the game.

The team uses AI to speed up workflows such as coding and other difficult tasks

Generative AI was used during production of some visual and audio assets. All generated material is selected, directed, edited, and integrated through a human-led creative process. The game does not generate content with AI during play.

AI-assisted. Developer-directed. Generative AI was used as a production tool during development: Claude assisted with prototyping and implementation, while Google Lyria was used to create the game's original 15-track soundtrack. The music and all other AI-assisted material were selected, edited, integrated, and play-tested by the developer to serve Boiler & Blood's dieselpunk folk-occult world.

Train Trek uses generative AI in two ways. During development we used AI tools to help make some assets: the user-interface art (HUD and menu icons, menu artwork, frames, button plates, mouse cursors), the instrumental soundtrack, and some sound effects. All of it was chosen, edited and finished by hand before it shipped. The 3D models are built procedurally by our own scripts, and the design, world generation and balancing are authored by hand. Parts of the source code were written with an AI coding assistant, reviewed and tested by the developer. While you play, the game speaks using a text-to-speech model that ships inside the game and runs entirely on your own computer. It voices tutorial guidance, hints and menu narration instead of pre-recorded audio. It needs no internet connection, sends nothing anywhere, and never records or listens to you. It only reads lines we wrote and shipped with the game - it does not invent dialogue.

Generative AI was used to enhance marketing assets such as steam capsule & early sketch concept before offloaded & polished by Humans. All gameplay, art, and final content remain crafted by Human.

Generative artificial intelligence has been used to create store page thumbnails based on the developer's scene work. Generative artificial intelligence has been used by the developer to vastly improve the performance of the developers code with respect to loading times. The developer struggled for months to figure out how to reduce a 30 second+ loading time and thanks to the contributions of gen AI that has been brought down to 5 seconds.

Some development used generative AI tools to assist with writing code, shaders, and drafting some in-game text. All content was approved by the developer.

This game utilizes AI-generated tools for store page imagery, in-game graphics, and portions of the programming.

In EverRail, AI-generated voiceover is used only for machine characters: the train's AI board computer and robot enemies, voices that are artificial in the story itself, which also lets us offer them in multiple languages. Beyond that, our team uses generative AI as a tool to support development, with our artists, designers, and engineers refining and hand-building every asset that makes it into the game.

We used AI to generate additional chat message ideas based on the initial list we made ourselves. Relevant message ideas were added to the game, some messages were altered to fit, and rest were left on the cutting room floor.

AI is used to enhance images and icons by applying filters and visual refinements to assets we originally created ourselves.

We have used AI to create some of the background artwork and BGM.

Selected in-game textures were created using generative AI, and some voice lines were generated using AI voice tools.

Some of the images in the game were generated using AI during the prototype stage. Such assets may be present in the game up until the release of the demo (inclusive). During the development process, we gradually get rid of generated assets and replace them with hand-made ones. By the time of the official release, all generated content will be removed. This is a normal process for developing an indie game.

This game actively supports human creativity, notably musicians and programmers - but uses AI in the design of marketing materials and some aspects of software development. Neither the game itself - nor the procedural generation techniques used to create the world, music, or audio - use AI or AI-generated art.

The informant's AI audio files are used on trains.

AI tools were used in a limited capacity during the development of the game, primarily to assist with certain programming tasks and the creation of temporary assets. No AI-generated content is created in real time while playing the game.

Generative AI Disclosure Some visual concepts, promotional images, text drafts, and background music were created or edited with the assistance of generative AI tools. The final materials were reviewed, selected, modified, and integrated by the developer. The game does not include real-time generative AI features during gameplay.

AI was used to assist with early concept sketches for some backgrounds and characters. Final in-game assets were edited and adapted by the developer.

As an indie project, this game uses machine translation for some of the languages. No AI was used for the source text, artwork or sound.

Generative AI was used for a very limited portion of the programming and for most of the English translation. However, all textures and 3D models were created by human artists.

1. In-game artwork Some visual assets (e.g., character/decor sprites, UI icons) are generated with Google Gemini and OpenAI ChatGPT (image generation) and further edited, retouched, and composed by the developer in the final art pipeline. 2. Store page and marketing graphical assets Capsule art, library hero, library capsule, and promotional images are generated with Google Gemini and OpenAI ChatGPT, and further edited, retouched, and composed by the developer before upload. 3. In-game localization Text translations are AI-assisted using Anthropic Claude, with developer review for tone and accuracy. Runtime behavior: - No generative AI models are bundled with or called from the shipped game binary. - All AI-generated content is pre-rendered and baked into final assets at build time. - No user inputs are sent to any AI service during gameplay.

AI assistance was used in creating some 2D & 3D assets, plus portions of text.

The development of this game involved the use of generative AI tools to assist in producing art and music assets included in the game content.

Some additional support in development, there is no dynamic generated code

Some parts of development used AI-assisted workflows, including asset creation, image processing/background removal, voice work, and localization of in-game/help text into multiple languages.

I’m a good programmer, but a terrible artist. So some of the images were created with the help of AI. By the time of release, I’ll try to remove all AI-generated images from the Steam page and from some textures in the game.

Some visual assets in the game were partially generated using AI tools and further edited by the developer. No AI-generated content is created during gameplay.

Generative AI tools were used during the development of this game to assist in the localization of in-game text and store page descriptions into multiple languages.
