An AI Game Companion is one implementation of Companion Play.
An AI Game Companion is a product or AI actor that supports a human player through game-state interpretation, memory, strategy, routing and continuity. It may be a dedicated application, but it can also be a general-purpose LLM connected to a game-tailored contract, captured state, portable data and a continuation interface.
An AI Game Companion can begin with a screenshot and an AI chat. In a live multimodal form, it can see the game screen, listen to the player, interpret unpredictable situations, remember earlier sessions and respond while play continues.
Screenshot or save state → game-state interpretation → portable Companion Save → game-tailored renderer → next action → continuity for the next session.
Dedicated application modelA standalone app provides voice, screen perception, commands, game modules and memory during play.
LLM + continuation layer modelA player uses a general-purpose LLM, a game-specific contract, screenshots, portable state and a tailored web renderer. No separate companion runtime is required.
Working implementation
Liquid Power Fantasy
Torchlight II GPT Companion began with a player sharing loot screenshots with GPT. The finished system uses a Companion Contract that asks for the relevant stats, skills, loot and progress screens. GPT interprets the run, validates game-specific facts and returns one portable JSON session bundle. The website then connects that state to the correct game assets and renders the player’s build, current route, milestones, next decisions, session timeline and a replayable adventure skit.
Documented origin case. Liquid Power Fantasy emerged from an actual Torchlight II play practice rather than a hypothetical app concept. On 28 May 2026, KONA was publicly described as no longer being “just a save file,” but an AI-native companion with persistent progression memory, timeline, skits, loot provenance and build routing.

1. Companion ContractDefines which screenshots and state the LLM needs.
2. State CaptureThe player supplies actual skills, stats, loot and progress.
3. LLM InterpretationGPT reads the run and keeps the player’s build fantasy coherent.
4. Portable JSONSave, skit and asset index travel as one session bundle.
5. Game-Tailored RendererThe site resolves exact assets and presents the run inside Torchlight II’s visual language.
6. ContinuationThe timeline, route history, skit and GPT handoff make the next session resumable.
Diablo IV / Path of ExileRead item stats, compare loot with the current build and suggest whether to equip, reroll, trade, keep or discard.
FactorioInterpret a factory screenshot, identify bottlenecks, broken ratios, power pressure and possible expansion routes.
CivilizationRead the current map, cities, resources, diplomacy and military position to give match-specific strategic advice.
Elden RingGive location-aware, build-aware and spoiler-sensitive hints based on the player’s current progress.
AI Game Companion names the implementation. Companion Play names the broader human-led mode of play in which external AI carries interpretation, memory and continuity across moments or sessions.
