What's in the Demo

This is not a sliced-down trial. It is a snapshot of everything Chrongrid can do today.

• Five complete, fully-playable stories — The Cat Hunt, My Week, Goodnight, Tomorrow, The Vortex Core, The Night Tide Aquarium — different in genre, pace, and play, ranging from gentle to deep;
  
• The current narrative orchestration engine — the full narrative loop, state propagation, and world-response mechanism are all in place;
  
• Everything you need to play, included — no account, no extra setup, nothing more to buy; just install and start;
  
• Architectural support for dozens of languages — multilingual stability varies considerably by story and model;
  
• Dual-window and single-window modes — switchable at any time.

To learn what each story is about, see "What's Inside" in the About This Game section below.

How the Demo Differs from the Full Version

The Demo is complete in content — all five stories are finished, fully-playable pieces, and you experience the full engine capability Chrongrid has at this stage.

But Chrongrid is built to keep evolving, and we don't believe our narrative orchestration engine — its capability, stability, and pacing — has yet reached the level we'd stand behind as a paid release. So we're putting the current version out as a free Demo first; when it truly reaches that level, we'll meet you again in the full version.

The single biggest difference the full version will bring is the upgrade of the narrative orchestration engine itself:

• Stronger orchestration — combat, negotiation, ensemble scheduling, and other scenes that today can only be rendered roughly will gain finer orchestration; player–world interaction will grow deeper and more natural;
  
• Steadier engine behavior — fewer parsing failures, better pacing across long stories, improved multilingual consistency.

Around the engine upgrade, the full version will also bring more official blueprints — their texts made public alongside the product, visible to you and editable by you — and Steam Workshop, where players create and share their own blueprints.

About save data: Demo save data cannot be carried over to the full version — we will be making substantial changes to the engine and blueprints before then, and save compatibility cannot be guaranteed. The Demo, however, will not be removed once the full version opens; you can keep playing in the Demo if you wish.

About the AI

Chrongrid's in-game dialogue, scene description, and character responses are generated in real time by an AI model that comes with the Demo — there is nothing extra to obtain or configure before you play.

• The AI stays inside the story — it generates dialogue and descriptive text only within the world, characters, and rules the author wrote into the blueprint;
  
• Generation takes time — a single narrative turn can take anywhere from several seconds to a minute or more depending on your hardware; the wait is real-time AI thinking, not a hang;
  
• A commitment to compliance — at the product-prompt layer, Chrongrid actively steers the model away from content that violates Steam's policies, and we will keep refining this as models and rules evolve.

Start with the Demo

We've built this machine and put it in front of you. The five stories are what we believe is most worth playing right now — but they are far from all of Chrongrid.

How far this goes from here depends on you and us together. Start with the Demo. We can't wait to see what you'll bring with Chrongrid.

About This Demo

Chrongrid is an AI-driven narrative orchestration engine. Inside the stories it builds, you are not reading a pre-written plot, nor are you picking options from a menu of buttons — you enter the story the way you want to, the world responds according to its own logic, and events grow from there, one step at a time.

What you can do: enter a preset story world, make your own choices, and let the world fill itself in dynamically as it unfolds. No journey ever repeats — not because the branches multiplied, but because the story is no longer a script written in advance. You may even arrive at endings the author never anticipated.

This free Demo comes with everything you need to play — five complete stories and the AI model that brings them to life. Your story content stays with you; nothing is sent to us.

What's Inside: Five Fully-Playable Stories

The Demo contains five complete stories, playable start to finish. These five fully independent stories — different in genre, pace, and play — take you from gentle to deep, showing different facets of what Chrongrid can do.

• The Cat Hunt — An early-summer afternoon in a Beijing hutong. You are A-Chen, a fourteen-year-old boy. Grandma Zhang's orange cat has gone missing. A warm starter story, and the most fundamental narrative loop in Chrongrid.
  
• My Week — You are a 23-year-old freelance illustrator. This week you have a commercial commission to finish and a market-day product to prepare. Every block of time is a choice; every choice has a cost. You decide how these seven days are spent.
  
• Goodnight, Tomorrow — The last night in a small port town. A case already closed, an old journalist friend, drinks and stories — both within reach. What kind of night this turns out to be is up to you.
  
• The Vortex Core — A ten-kilometer-wide vortex appears in the western Pacific; a tsunami swallows the entirety of Japan. You are the chief scientist aboard the research vessel Qiming — the human being closest to the truth.
  
• The Night Tide Aquarium — You are the night security guard at an old aquarium. Tonight, for eight hours, you are alone with this place. The manager has handed you a list of eight rules and said: "Follow them, and you'll make it to morning."

These five stories are a snapshot of what Chrongrid can do today. We are still polishing — by the full release, we will bring richer, deeper stories with more replay value.

How to Play Chrongrid

About the AI

The Demo comes with its AI model included — you don't connect or set up anything to play; just launch and start. Generation speed depends on your computer's hardware (see "current limitations" below).

About presentation

Chrongrid offers two window modes, switchable at any time:

• Dual-window mode — the Launcher and Container windows run independently. You enter your actions in the Launcher, while the narrative unfolds in the Container. Strong sense of immersion. Dual-window mode is the recommended default.
  
• Single-window mode — only the Launcher runs. Your input and the narrative both appear inside the Launcher window. This is the traditional, classic approach.

About languages

On first launch you'll enter the Beilin — dozens of language stones laid out in sequence, from which you pick the one you want to play in. The multilingual capability during play is provided by the AI model.

About current limitations

Three things we want to say before you open the Demo:

• Multilingual experience is not yet stable — Chrongrid supports dozens of languages by architecture, but the AI's linguistic ability varies by language. Chinese and English are currently the most reliable. If, at the start of a story, the displayed language doesn't match the one you selected, we strongly recommend opening a new story and trying again.
  
• AI replies take time — a single narrative turn typically takes from several seconds to a minute or more, depending on your hardware. Chrongrid does not pre-generate content; the wait is the price of real-time AI thinking. We will keep optimizing it — but it will not disappear.
  
• Occasional parsing failures — when the AI returns malformed content, Chrongrid may not parse it correctly, and a scene can stall. This usually does not block you from continuing. If it happens repeatedly, opening a new story usually helps.

These are honest realities of AI-driven products today. We won't hide them — we'll keep pushing them down, one at a time, as the model and the orchestration layer improve.

Boundaries of Generated Content

The story content in Chrongrid is generated in real time by the bundled AI model. At the product-prompt layer, we actively avoid content that violates Steam's policies, and we'll keep refining this as rules and models change.

But the final output is decided by the model — its training and the way players guide it during play can push it to produce content beyond what we anticipate. Please keep your inputs within reasonable bounds — this is also the foundation for a good play experience.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Chrongrid Demo is a narrative experience product powered by a large language model (LLM). In-game dialogue, scene descriptions, and character responses are generated in real time by an AI model that ships fully bundled inside the Demo — no external service, no account, no API key, no internet connection required after install. The Demo includes llama.cpp (MIT) and the Qwen3.5-9B-Q4_K_M model weights (Apache 2.0) as part of the depot; all inference happens locally on the player's own machine. The AI generates dialogue and descriptive text at runtime, always within the constraints of pre-authored narrative blueprints, characters, and world settings.
