About this extension
Do you often spend a significant amount of time reading web pages? Do dense policies or highly technical articles leave you feeling overwhelmed? Do you struggle through foreign-language texts, only to end up with a partial understanding? Or perhaps you need to extract specific information of interest from lengthy articles, or transform a serious, formal piece into engaging social media copy that instantly grabs a reader's attention?
Why not give Firefly AI a try?
It helps you browse the web with ease, offering real-time translation and intelligent content analysis. It can extract data from tables within a page—and even effortlessly transform web content into various writing styles.

🌟 Key Features:

Analyze the web page you are currently viewing—or extract specific content of interest—either by utilizing specialized "Agents" or by engaging in a direct conversation with the AI.

Pre-set Agents include:
* Search: Scan the web page content for specific keywords or phrases, helping you quickly locate the information you need.
* Explain: Clarify the web page content to help you better understand its meaning.
* Summarize: Condense the web page content to help you quickly grasp the main points.
* Translate: Convert the web page content into other languages, enabling you to understand pages written in different tongues.
* Extract: Pull specific information or data points directly from the web page content.
* Convert: Transform the web page content into different formats or types, making it easier for you to utilize the information.
* Rewrite: Rephrase the web page content to help you better understand and apply the information.
* Reply: Automatically generate responses for emails or chat messages within web-based interfaces.

Custom Agent Feature:
In addition to Firefly AI's built-in agents, you can create your own custom agents by defining specific AI prompts and quick-access options tailored to your unique needs. Click the gear icon in the top-right corner to open the Settings page -> select "Agents" -> then click the "+" button in the bottom-left corner to begin creating your own custom agent. Your custom agents will appear within the menu of the "Run Agent" button located in the bottom-left corner of the chat interface, as well as in the floating toolbar positioned on the right side of your browser window.

Chat History:
Your conversations with the AI ​​are automatically saved as a historical record. You can use the "New Session" button located in the bottom-left corner to start a fresh, distinct conversation for each different web page you visit. You can access your past conversation records via the "Session History" button located in the top-right corner. By selecting any specific record, you can view the previous exchange and resume the conversation from that point.
Note: While the session history does record the specific webpage URL that was being read at the time, new conversation content is always contextualized to the currently open webpage. This means that if you resume a session while a different webpage is open, subsequent responses will be based solely on the content of that new page, and the webpage URL recorded in the session history will be updated accordingly.

Multi-language Support:
Supports English, Simplified Chinese, Traditional Chinese, Japanese, and Korean.

🌟 How to Install and Use
  • Install the Firefly AI extension either directly from the extension store or by downloading and installing it manually.
  • Open any webpage containing content you would like the AI ​​to read.
  • Click the extension icon in your browser's toolbar, or click the floating toolbar button positioned on the right side of the webpage (this floating button feature is not available in Firefox) to open the extension's sidebar.
  • Enter any questions you have regarding the current webpage into the chat box within the sidebar.
  • Alternatively, you can access the list of available "Agents" by clicking the "Run Agent" button in the bottom-left corner, or by typing the / command into the chat box; simply select an agent to execute a specific task.
  • Click the "Session History" button in the top-right corner to view a complete record of all your past conversations with the AI.
  • You do not need to log in to use Firefly AI; however, logging in grants you access to additional features and increased usage quotas. Click your user avatar in the top-left corner to navigate to the login page, where you can log in using your mobile phone number and a verification code.

🌟 Privacy and Security

To ensure your convenience while using Firefly AI, the extension displays a floating toolbar on the webpages you visit (this floating toolbar feature is not available in Firefox). This toolbar allows you to quickly initiate a conversation to read and analyze the webpage content. It will not interfere with or alter the webpage you are viewing. If you find the position of the floating toolbar inconvenient, you can click and drag it vertically with your mouse to reposition it.

Firefly AI will only read the content of a webpage when you actively launch an Agent or initiate a conversation. It will never automatically read or interact with a webpage without explicit user action.
