Character.AI Legacy Chats is a Chrome extension developed by József Sallai. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. The extension adds a button to Character.AI chat pages, allowing users to create new chats using the legacy/old chat interface.

The purpose of this extension is to provide users with access to the old chat interface, which offers features that are currently missing in the new interface. For example, users can upload images in conversations using the old interface. Some users may prefer the old interface due to these missing features or because it simply works better for them.

The extension is safe to use as it only adds a button to the web page, which sends a request to the legacy chat endpoint for creating a new chat. It does access the user's authentication token from the browser's local storage, but this is only necessary for the request to function properly. The extension does not misuse or access any other user data.

However, it is important to note that using this extension may carry some risks. While it is unlikely, there is a possibility that using the legacy endpoint could be detected by Character.AI, and the consequences of this are unknown. Therefore, users should exercise caution and understand that they are using the extension at their own risk.

Unfortunately, the extension is not currently available for Firefox. However, it can be used on any Chromium-based browser such as Brave, Edge, or Opera. Additionally, users with knowledge of userscripts can create a basic userscript to achieve the same functionality.

Please note that this extension is not compatible with the mobile version of Chrome, as extensions are not supported on mobile devices.
