World Card: an open JSON draft and browser-local Lorebook converter

[CrushOnAI]

Hi everyone — we have published an early World Card draft and a small, free converter for experimenting with portable worldbuilding data across roleplay tools.

This project is maintained by CrushOn.AI and shared as an open draft for technical feedback from the wider roleplay tooling community.

The current tested path accepts a SillyTavern Lorebook JSON and converts supported entries into a documented normalized structure. The web version runs entirely in the browser: the selected file is not uploaded to an application server. Generated output defaults to Private visibility and Filtered rating.

• Live converter: https://huggingface.co/spaces/CrushonAI/world-card-converter
• Repository and specification: https://github.com/CrushOnAI/world-card
• Conversion example: https://github.com/CrushOnAI/world-card/blob/main/docs/conversion-example.md

The adapter currently handles entries supplied as an object or array, skips disabled or empty entries, and maps Characters, Locations, Organizations, Events, Rules, and Items. Unknown categories need an explicit fallback note type.

We are deliberately describing the result as normalized structural JSON, not as an official native CrushOn export. The repository documents the tested scope and includes SFW fixtures and automated tests.

Feedback would be especially useful on:

1. Lorebook fields or edge cases that should be preserved but currently are not.
2. Whether the proposed note-type mapping feels predictable.
3. Additional sanitized fixtures we should add before calling the adapter broadly compatible.

Update: World Card Converter v0.2.0 is now available.

The browser-local converter now shows a conversion and field-mapping report before download, including:

• source, converted, and skipped-entry counts;
• disabled, empty, and invalid skip reasons;
• fallback categories and duplicate keywords removed;
• unsupported source fields and the tested field mapping; and
• JSON line and column details when the browser exposes a parse position.

Release notes: https://github.com/CrushOnAI/world-card/releases/tag/v0.2.0

Live demo: https://huggingface.co/spaces/CrushonAI/world-card-converter

The compatibility boundary remains unchanged: the output is a documented normalized structural JSON target, not a claim of lossless conversion, full SillyTavern compatibility, or official native CrushOn import/export support.

Feedback is especially welcome on unsupported Lorebook fields, confusing fallback behavior, and sanitized edge cases we should add to the fixtures.
