The extension is compatible with chromium browsers (Opera, Opera GX, Brave, Vivaldi, Chrome, MS Edge) and Firefox (developer and Nightly versions only).
The extension can work on Android with browsers that allow loading extensions via zip like Kiwi Browser or Flow Browser.

The mobile versions have a design exclusively designed for mobile devices.

There are three versions of the extension with different accessibility.

• Free version (Google Chrome Store, coming soon)
• Patreon version
• Premium Patreon version

The free version (Lite) is available on:
Chrome Web store
Firefox Add-ons

And offers access to:

• Add custom chat background image
• Get detailed information from the bot
• Temporarily censor names and avatars for taking screenshots

The basic Patreon version offers access to most of the features on the feature list, including the powerful memory manager and access to the conversation history with a custom design that you can download.

The premium Patreon version offers extra cloud services such as a personal image gallery to change user and bot avatar images per session, change user and bot names per session, or store and auto-load memory manager files automatically in the cloud.

You can download the full version from here. (Requires login with a Patreon account with an active subscription)

Summary of features (as of version 1.7.1) - ALL features work for both cai+ and regular users.

Features of the Lite version
Features of the Basic version
Features of the Premium version
(*) Each tier includes the features of the previous tiers.





Features of the Lite version:
The Lite features work in both chat1 and chat2.

• Custom chat background image

With this option, you can change the chat wallpaper to have a unique design. This feature also allows you to make visible or not a darkening in the chat column to create a soft blur effect.

• Detailed information from the bot

By clicking on the bot's name in the top bar, you can open a window with detailed information about the bot. This includes the greeting and description of all bots regardless of their visibility, including the hidden ones. And their definition. The definition is only visible on bots that have definition visibility enabled.

• Temporarily censor names and avatars for taking screenshots

In the upper contextual menu, you have a couple of options to censor names and avatars of all messages, or just your messages, so you can take screenshots without revealing information you are not comfortable with.

Features of the Basic version:

• Powerful memory manager

The memory manager allows you to note down relevant facts that the bot should not forget.
Such as the features of your character or the bot itself, the place where it is, fundamental facts of the story (like you and the bot are dating, a secondary character died, etc).

The notes you jot down in the memory manager are injected into the bot in various ways.
By default, they are injected along with your message every 4 messages. You can configure the injection frequency or perform other advanced injections such as keyword or manual injections.

• Favorites System

Add your favorite bots to favorites. Bots added to favorites are registered in a special window that gathers your favorite bots and allows you direct access to them, even from the chat page of another bot.

You can also quickly check the bots you've added to favorites from the main page.

• Chat History

Opens a complete history with all messages from the current conversation.
You can also download it for local use while retaining the web layout.

• Large avatars

You can choose between traditional avatar images or large avatar images for greater immersion.

• Text customization

Customize the font type, its size, and the text and narration colors for a more pleasant and better visual experience.

• Swipe counter

With the swipe counter, you will always know which generated message you are on, allowing you to easily memorize or jot down your favorite messages before making a decision.

• Auto-close the "Try again" window

Self-explanatory. When the annoying filter popup appears, it goes away immediately and automatically.

Features of the Premium version:

If you are part of the wonderful premium supporters, you will have access to a new panel with extra features. Which for now are:

• Online memories

Gone are the days of manually saving and loading your memory files in each chat of each bot. If you are premium, not only are your files stored in the cloud accessible from any device and location, but the system also remembers which file you loaded/saved in each bot and automatically loads it when you enter the chat!



The buttons do the following:
Load: Fills the current memory manager with all the information from that memory file.
Save: Overwrites the selected online file with the current state of the memory manager. If you edit the memory manager, don't forget to save!
Delete: Permanently deletes a file from the list.
Create: Creates a new file based on the current information in the memory manager. It's similar to saving, but creates a new file instead of overwriting the current one.
Clear: Empties all fields in the memory manager. Useful if a file has auto-loaded but this time you want to opt for something else.

• Customize Session

Here you can configure the most personal and aesthetic part of the chat.
You can select a name for your character, another for your bot, and the same for the avatar images. The system will also remember the settings established for each bot and will automatically load them when entering a chat.



The buttons do the following:
Chose File: Select an image to upload to your gallery.
Upload Image: Upload the selected image to your gallery.
Reset to Default: Removes changes in images and names for the current bot.
Save Changes to This Session: Saves the current changes in images and names to the bot. If you don't do this, the changes will only be temporary and will be lost if you refresh the page or close the browser.
Load Changes from Previous Session: The changes apply to a chat session, not to the bot. This means that two chat sessions can have different settings. (So by switching sessions in the chat history you can have one set of names and images or another). If you're in an uncustomized session, this button will load information from a previous customized session, if it exists.

Note: Each premium user has a 40MB image quota. This means you can have 2 images of 20MB each, or 80 images of 512KB each. If you want to have the most images possible, try using small and lightweight images.

• Customized titles

If you click on the title of a memory box, you can customize the text to classify your boxes. For example, as "Appearance," "Current Location," etc.
This change is only for aesthetic and organizational purposes.
These changes are permanent and are saved and loaded with the specific memory file.

• Customized individual injections

This feature is included within the previous one.
Within the title name of the memory box, if you put a text in brackets at the end, that text will be used to display the injection instead of an asterisk.

• Review injection content

You can check the injected content in two ways:
1) Holding the cursor over the injection (desktop view only with mouse)
2) Clicking on the injection

(*) This also works in the chat history.

• Custom tags

You can use {{char}} and {{chr}} within the information of a memory box to replace the bot's name.
If the bot has a compound name, like "Hoshino Ai":
{{char}} will be equivalent to using "Hoshino Ai"
{{chr}} will be equivalent to using "Hoshino" (the first part of a compound name).

• Open favorites from within a chat

You can open the favorites window from the main menu on the homepage, but also from the chat page:

1) Right-clicking and selecting "CharacterAI Extra - Bookmarks" from the context menu (Desktop view with mouse)
2) Tapping with two fingers (mobile view)

These guides are only for the Patreon subscriber versions. (The Lite versions do not need an installation guide as they are installed from the stores).
It will be assumed that you have already downloaded the corresponding file for your browser from the download section.

Installation on Chromium browsers
Installation on Firefox
Installation on Android






Installation on Chromium:

The extension should work on any browser based on Chromium.
It has been tested for proper functionality on Edge, Opera, Opera GX, Vivaldi, Brave, and Chrome.

You must unzip the extension zip file in a fixed directory on your system (it must not be moved from there).
Then, in your browser you must go to the url and activate the developer mode:
chrome://extensions (If your browser is not Chrome, this may not work; simply go to the browser's extension section.)

After that, you can add your extension by clicking on this button, and selecting the folder where you unzipped your extension.
(the directory containing the manifest.json file)
Your extension is now loaded and ready to enjoy!
Make sure it is activated:

To update the extension, overwrite the files of your extension with the updated ones and click the reload extension icon.

Installation on Firefox:

Keep in mind that you can only install the extension on DEV or NIGHTLY browser versions (Dev highly recommended, which is the same version as the beta but with extra features).

You should note that consumer versions (stable and beta) do not support external extensions, so it is not possible to install the extension on those versions.
You can download Firefox Dev here

To install, follow the following steps in your version of Firefox Dev:
Enter the following url in the address bar of your browser:
about:config

enter the following:
xpinstall.signatures.required

Double-click on the row that appears to set it to false.
From this point the process to install and update the extension is the same (If you update, do not delete the previous version, so you will keep your configuration).
Go to extensions or enter this url in the address bar:
about:addons

Go to extensions menu and drag the extension you downloaded for Firefox (zip file) onto the extensions screen.
Click anywhere in the extensions window (or wait a few seconds) and the following window will appear where you can click on "Add".

Now you must go to the character.ai website, and on the extensions button at the top right allow the extension to work on the website:

Make sure that all permissions are enabled:

Your extension is now loaded and ready to enjoy!

Installation on Android:

The first thing you will need is a browser that supports loading local extensions. In this guide we will use Kiwi Browser. (Flow browser is valid too)

Click on the 3 dots and then select extensions.

On the extensions page, developer mode is probably enabled by default, but if it is not, make sure it is by checking the top right corner.

In my case it can't be seen in portrait mode, so I had to put my phone in landscape mode.
Once the developer mode is activated, select the "from crx" option.

You can install both the Android version (crx) and the Chromium version (zip).
The Chromium version may be more compatible. Try the Chromium version if you have problems with the Android version (which requires accepting all permissions in the extension details)


This will show our extension as loaded.

To update the extension just repeat the same thing. Add again a crx/zip file without deleting the current version of the extension.
Now we must go to a chat of our choice, and once in the chat, reload the page if you can't see the small blue box.

Then the blue button will appear that allows the magic to happen.

In this state (when the extension is loaded) you can check the content of the injections by clicking on them (it will not work if the extension is not loaded).



Now we will have access to all the functions of "Rinine CharacterAI Tools". Including a special mode of large images for mobile.
