I’ve released **Notebook Injector (NI)**, a framework for modders who want to add new content to the in-game Notebook without having to rebuild the same system for every mod or rely on traditional XML overrides of EA’s notebook resources.



With NI, creators can:

* create custom categories and subcategories;
* add entries to custom or compatible existing sections;
* use built-in support for recipes, bait, animal feed, country items, gardening plants, and standard entries;
* build fully configurable **CUSTOM entries**, including text blocks, ingredient lists, footers, and custom tooltips;
* automatically allocate enum values and detect common name or value conflicts;
* validate integrations and generate detailed troubleshooting logs.

The goal is to make Notebook-based mods easier to create, safer to combine, and simpler to maintain after game updates.

For players, NI works as a shared dependency: install it once, and compatible mods can add organized new content to your Sims’ Notebook. NI does not add gameplay content by itself.

The source code, documentation, templates, and in-game screenshots are all available publicly on GitHub.

# I’d be interested to hear what kinds of Notebook-based mods creators would like to build with it.
