The visual novel development tool allows you to use a script format closer to natural language (e.g., English) writing and create demos with minimum effort, enabling visual novel development with a smaller feedback loop (effort to outcome).
What you need to feed into the tool:
Story scripts (docx/odt documents, markdown, plain text)
(Optional) assets (backgrounds, character sprites, music, etc)
What you can get from the tool:
Game engine project files (scripts and converted/generated assets)
Statistics & Reports (WIP)
We currently support Ren'Py and WebGal (experimental) as backends.
This is a free-and-open-source project. We also had a paper, "PrepPipe: Prototyping Compiler for Attainable Visual Novel Development," DOI: 10.1109/CoG60054.2024.10645615
WARNING: This tool is still under development. This store page is not in its final shape, and we will update it during the development. The current release is mainly for testing. USE THIS TOOL AT YOUR OWN RISK. We will try hard to fix issues ASAP, however.
