1 | # AI warning for Steam
2 |
3 | Shows the _AI Generated Content Disclosure_ on Steam store pages as a modal popup.
4 |
5 | 
6 |
7 | If a Steam store page contains an _AI Generated Content Disclosure_, this extension will display it as a modal popup, instead of just at the end of the page. Additionally, it will blur out the rest of the page until the popup is dismissed.
8 |
9 | ## Installation
10 |
11 | **AI warning for Steam** can be installed as a native browser extension for Firefox or Chrome, or as a userscript for any supported browser. All variants run the exact same code, so installation and updates are the only differences.
12 |
13 | ### Option 1: Install as a browser extension for Firefox or Chrome
14 |
15 | This is the easier option, but updates can sometimes be delayed, because Mozilla and Google need to approve them first. (Usually this shouldn't take more than a day.) Just follow the appropriate link for your browser and click the install button.
16 | - [Firefox Add-ons](https://addons.mozilla.org/firefox/addon/ai-warning-for-steam/)
17 | - [Chrome Web Store](https://chromewebstore.google.com/detail/ai-warning-for-steam/clegcobheppnnigaaeelfkeomjcngmnh)
18 |
19 | ### Option 2: Install as a userscript
20 |
21 | This option is slightly less straight-forward, if you've never used a userscript, but you get updates as soon as they're available.
22 | 1. If necessary, install a userscript manager for your browser, for example by following the instructions at [Greasy Fork](https://greasyfork.org/#home-step-1).
23 | 2. [Click here to install the userscript](https://github.com/seeeeew/aiwarningforsteam/raw/refs/heads/main/aiwarningforsteam.user.js) _or_ download [`aiwarningforsteam.user.js`](https://github.com/seeeeew/aiwarningforsteam/blob/main/aiwarningforsteam.user.js) to install it manually.
24 |
25 | ## Platform and Language Support
26 |
27 | The native browser extension should work in any up-to-date version of Firefox, Chrome, or any related browsers that can install extensions from the same sources, on any desktop OS. The Firefox version also works on mobile systems.
28 |
29 | The userscript should work in any up-to-date browser with userscript support on any desktop or mobile OS.
30 |
31 | The extension supports all languages officially supported by the Steam store, but the download/installation pages as well as metadata like the extension description are only available in English.
32 |
33 | ## Project Scope
34 |
35 | This extension's sole purpose is making the _AI Generated Content Disclosure_ impossible to miss on Steam store pages where it exists. Future updates might improve this functionality, but will not add unrelated features.
