About Add Anything

Add Anything lets you customize any website by adding your own HTML, CSS, and JavaScript — no developer console required. Features: - A side panel editor for writing HTML, CSS, and JavaScript snippets - Apply a snippet to all pages, or restrict it to specific sites using comma-separated regular expressions (partial or fully-anchored matches) - Enable/disable individual rules without deleting them - Changes apply live — no need to reload the extension Everything you create is stored locally on your own device via Chrome's storage API. Add Anything does not collect, transmit, or share any data, and makes no network requests of its own. See the privacy policy for details. Typical uses: personal dark-mode overrides, hiding annoying page elements, quick prototyping of CSS/JS tweaks, accessibility fixes, or adding small widgets to pages you use often.
