Capsule VN Engine
Empower Your Stories. Build Your Visual Novel.
Welcome to the Capsule VN Engine!
Capsule VN Engine is a modern, web-based tool designed with one obsession: removing the friction between your idea and your players. Whether you are a seasoned developer looking for a rapid prototyping tool or a complete beginner writing your first interactive story, Capsule handles the technical complexity so you can focus on creating.
The Philosophy: Why "Capsule"?
The name "Capsule" defines the engine's unique architecture and purpose:
- All-In-One Containment: Just like a space Capsule carries everything needed for a mission, a Capsule game file (game.html) contains your entire game—engine, assets, scripts, and save system.
- Zero Dependencies: A Capsule game doesn't need a server, a database, or an installation wizard. It is hermetic and autonomous.
- Ultimate Portability: A Capsule is made to travel. Send your game via email, drop it on Discord, or host it on any static web page. If a device has a web browser, it can run your Capsule.
Bridging the Gap: For Beginners & Developers
Capsule VN Engine was built to solve specific pain points for both ends of the spectrum.
For Beginners: "Zero Code, Zero Stress"
If you have never written a line of code in your life, this engine is for you.
- Visual Interface: Everything is done via the Studio interface. You type text, choose colors with a picker, and select images from your folder.
- Real-Time Feedback: The "What You See Is What You Get" (WYSIWYG) preview window lets you see your changes instantly. No need to "compile" or wait.
- No Setup Required: Forget about installing Python, setting up a local server, or configuring libraries. Open the Studio, and you are ready to create.
For Developers: "Streamlined Efficiency"
For experienced devs, Capsule acts as a powerful accelerator.
- Rapid Prototyping: innovative architecture allows you to build and export a playable build in seconds.
- Asset Management: The engine handles Base64 encoding automatically, removing the need for manual asset bundling or path management.
- Clean Architecture: The output is standard, clean HTML/JS. It’s lightweight, performant, and follows modern web standards without the bloat of heavy frameworks.
Let’s write the future of Visual Novels together.

Seems fine, mechanics look good, but can't change the language to English...
Hi,
Thanks for your feedback. If you're referring to the application itself, it's normally set to English by default. Otherwise, you need to click the button to change the language in the menu at the top right.
If you're referring to the visual novel preview on the right, it's possible that the preview was displayed in French.
In that case, click on "Config." This will display the visual novel's start screen. There, click on "Options" in the preview screen and select English. This should fix the problem and save your preference locally in your browser. So, every time you log back in, it will be in English.
Let me know if this resolved the issue.
Thanks!
I tried all that. It didn't work.
Hi Goliard,
Can you add a screenshot please? I just tried with Edge, Opera and Chrome and it's working.
EDIT: I've been working on a new multilingual model; now the application appears in English by default, both the application itself and the preview. This should have resolved your issue.
To add other languages, you need to click the "CONFIG" button. If you change the interface language and have added the language via "CONFIG", the preview will change dynamically.
