Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“This game utilizes a locally-running AI model, which is a technically demanding feature. Since performance can vary significantly depending on the user's PC hardware (CPU, GPU, and RAM), we decided to launch in Early Access to gather real-world performance data. This will help us optimize the AI execution and ensure a smooth experience for a wide range of machine specifications.”

Approximately how long will this game be in Early Access?

“We plan to keep the game in Early Access for approximately 6 to 12 months. This period will allow us to collect sufficient feedback, fix hardware-specific compatibility issues, and refine the AI's responsiveness before the full release.”

How is the full version planned to differ from the Early Access version?

“The Early Access version provides the core experience of the concept café simulation and local AI conversation.

The full version is planned to include:

Optimized AI performance for a broader range of machine specs.

Improved stability and bug fixes based on community feedback.

Additional customization options and expanded dialogue scenarios.
Our goal is to release a polished version where the local AI interaction is seamless and accessible to as many players as possible.”

What is the current state of the Early Access version?

“The current version includes the fundamental gameplay of the café simulator and the core local AI conversation system. Users can interact with characters through text and experience the VRM model import feature. While the main loop is playable, the game requires further optimization for various PC configurations, and some UI elements and additional content are still under development.”

Will the game be priced differently during and after Early Access?

“We plan to gradually raise the price as we ship new content and features. Early adopters will benefit from a lower price during the Early Access phase as a token of our appreciation for their support and hardware-specific feedback.”

How are you planning on involving the Community in your development process?

“Community feedback is crucial for our development, especially regarding the performance of the local AI on different hardware. We encourage players to share their experiences, bug reports, and hardware specs via our Steam Discussion forums. Your input will directly influence our optimization priorities and the addition of new features.”

About This Game

Welcome to Concept Café Simulator

Concept Café Simulator is an AI talk game where you create concept café staff members, known as “casts,” and enjoy conversations with them.
Because the AI responds as the cast, every conversation is different.

Cast Creation

Choose from five base avatars and customize details such as hairstyle, clothing, and accessories. The game also supports importing VRM files, allowing you to use your favorite 3D models as casts.

Create each cast’s personality by setting their name, first-person pronoun, and speaking style. You can choose from 10 speaking styles, including “Polite,” “Casual,” “Elegant Lady,” “Tsundere,” and “Yandere.” You can also set their favorite topics from over 100 categories, covering a wide range of genres such as anime, games, music, cooking, and sports.

Conversations with AI

The game includes a local LLM, allowing you to have conversations without an internet connection. Your conversation data is never sent to external servers. In addition to text input, voice recognition input is also supported.

Casts Remember You

Casts learn and remember information from your conversations with them. They can remember things you have talked about, such as your favorite foods, hobbies, and work, and use that information in future conversations.

Depending on the number of visits and the content of your conversations, 12 emotional parameters such as affection, trust, interest, and excitement will change, deepening your relationship with each cast.

Voice Synthesis

Japanese voice synthesis powered by VOICEVOX is included. You can choose from 15 different voices for each cast. Cast expressions change automatically based on the conversation, and lip-sync is also supported.

Five Cafés

The game includes five café spaces, each with a different theme. You can assign a different café to each cast.

AI Generated Content Disclosure

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

This game utilizes a locally-running Large Language Model (LLM) to power the conversation system with characters.

Live-Generated Content: The dialogue and text responses from characters are generated in real-time based on user input.

Local Execution: All AI processing happens locally on the user's hardware; no data is sent to external servers for generation.

Pre-rendered Content: Generative AI was not used for any visual artwork, UI, or music included in the game. All assets are handcrafted or created using traditional development tools.

Mature Content Description

The developers describe the content like this:

Mature Content Description:
This game contains content that may not be appropriate for all ages. Default characters may appear in swimwear or revealing outfits.

As this game supports custom VRM model imports, the presence of more explicit content depends entirely on the files the user chooses to load.

Important Note: This is a single-player offline experience. Users will not encounter any sexual content unexpectedly from other players. Explicit nudity or mature themes only appear if the user intentionally imports and uses such models.
