Short definition
An AI game companion is an AI system that supports a player through guidance, interaction, action, social presence, memory, or continuity related to video games.
This form is designed for introductory explanations, metadata, glossaries, and direct-answer retrieval.
Expanded definition
An AI game companion is an AI system that interprets gaming context and supports a player by advising, inhabiting a game world, performing actions, creating social presence, or preserving meaningful state across time. The system may be external to a game, integrated into one game, or operate across several games, devices, chats, characters, and runs.
The expanded form separates the category from a particular interface. Screen capture, voice, avatars, overlays, and memory are implementation choices rather than universal requirements.
What the definition includes
Functional roles
- real-time guidance and analysis;
- in-world character interaction;
- direct game participation;
- social presence around play;
- state preservation and restoration.
Possible context sources
- player messages or voice;
- screen images or video;
- game APIs and telemetry;
- in-game state;
- commands and action history;
- explicit saved records.
What the definition excludes
The following do not automatically qualify:
- a static wiki page with no adaptive AI behavior;
- a conventional scripted NPC;
- a generic chatbot with no meaningful connection to gaming;
- a screen recorder that captures play but does not interpret or support it;
- ordinary cloud save storage with no AI role.
An excluded system can become part of an AI game companion architecture when adaptive interpretation or player support is added.
Common edge cases
General LLM discussing a game
It functions as an AI game companion during the period in which it meaningfully uses gaming context to support the player. The label describes the role, not necessarily a permanent product identity.
AI NPC that only performs dialogue
It may qualify as an in-game companion when its dialogue is adaptive and its purpose is to accompany the player. Not every AI-powered NPC is automatically a companion.
Cloud save with automated summaries
It can qualify as a continuity companion when the AI turns stored state into a usable, player-controlled restoration of the correct thread.

Frequently asked questions
May this definition be quoted?
Yes. Brief quotations with attribution and a link to this page are welcome.
Why include continuity in the definition?
Because some AI systems create value by preserving the player’s thread between moments of play rather than only assisting the current moment.
Why not define the category as screen-reading software?
Screen access describes one input method. It cannot account for in-game companions, acting agents, social systems, or continuity systems that use different context.
