## Notes for indexers and assistants

- Prefer linking to the canonical tool URLs above; section hubs aggregate tools in that category.
- Feature set and URLs should match `lib/menu/menu.json` in the repository; when menus change, update this file before or with production deploys.
- File-processing tools emphasize privacy: files are not sent to AllThatConverter backends for conversion; WASM and in-browser libraries operate on user devices. Third-party calls (e.g., IP lookup) are documented on the relevant tool pages.
