"Chat With Me" Chrome Extension

Overview

The "Chat With Me" Chrome Extension is a simple browser extension that allows users to interact with a chatbot powered by OpenAI's API, using LLM. Users can send messages, receive responses, start new chat sessions, and manage chat history.

Functional Requirements

1. User Interface: A popup HTML page (popup.html) that includes:

   • A container to display chat sessions.
   • A container to display the chat conversation.
   • An input field for user messages.
   • Buttons for sending messages, starting new chats, and clearing chat history.

2. Chat Interaction:

   • User is asked to add the OpenAI API key the first time that the extension is run.
   • Users should be able to type messages and view bot responses within the chat container.
   • The chat interface should differentiate between user messages and bot responses with distinct styles.

3. Session Management:

   • The extension should save chat sessions persistently using Chrome's storage API.
   • Users should be able to view a list of saved chat sessions and select one to view its content.
   • Users should have the option to start a new chat session, which saves the current session and clears the chat container.
   • Users should have the option to clear all chat history after a confirmation prompt.

4. OpenAI API Integration:

   • The extension must be able to send user messages to the OpenAI API and display the bot's responses.
   • The extension should handle API authentication by storing and retrieving the OpenAI API key using Chrome's storage API.

5. Error Handling:

   • The extension should display an error message if communication with the OpenAI API fails.
   • The extension should prompt the user to enter their OpenAI API key if it's not already stored.

Technical Requirements

1. HTML/CSS/JavaScript: The extension must be implemented using standard web technologies: HTML, CSS, and JavaScript.

2. Chrome Extension API: The extension must use the Chrome Extension API to interact with browser features, such as storage and scripting.

3. OpenAI API: The extension must integrate with the OpenAI API, requiring the host_permissions to be set for https://api.openai.com/*.

4. Styling: The extension should use a styles.css file to define the look and feel of the chat interface, ensuring a user-friendly experience.

5. Manifest File: The extension must include a manifest.json file with the necessary metadata, permissions, and settings for a Chrome Extension.

Security Requirements

1. API Key Storage: The OpenAI API key should be stored securely using Chrome's storage.sync API.

2. Input Validation: User input should be properly sanitized before being sent to the OpenAI API to prevent injection attacks.

Testing Requirements

1. Functional Testing: Verify that all user interactions work as expected, including message sending, session management, and error handling.

2. Performance Testing: Ensure that the extension performs well, with no significant delays in message sending or session loading.

3. Security Testing: Test for potential security vulnerabilities, particularly in the storage and handling of the OpenAI API key.

Deployment Requirements

1. Packaging: The extension should be packaged as a ZIP file containing all necessary files for distribution.

2. Installation Instructions: Provide clear instructions for installing the extension in Chrome, including how to load an unpacked extension for development and testing.

3. User Documentation: Include a user guide explaining how to use the extension, manage chat sessions, and configure the OpenAI API key.

Support and Maintenance

1. Issue Tracking: Implement a system for users to report bugs or suggest enhancements.

2. Updates: Plan for periodic updates to the extension to address user feedback, add new features, and maintain compatibility with Chrome and the OpenAI API.
