Chat²GPT is a ChatGPT chat bot for Google Chat 🤖💬. It's designed to amplify the experience in your Google Chat rooms by offering personalized user sessions for coherent dialogues, a manual reset capability, the power to generate images via OpenAI's DALL·E 2 API, and dynamic interactions through mentions or direct messaging. Moreover, with the integration of ElevenLabs' Text-to-Speech API, Chat²GPT now brings voice interactions, letting users convert textual prompts into audio. User input and text output is moderated with OpenAI's Moderation API.

🛠️ Setup

This bot is intended to be deployed on Google Cloud Functions, with audio data temporarily stored in Google Cloud Storage. Its continuous deployment pipeline is managed using GitHub Actions.

Follow these steps to setup your Chat²GPT bot:

1. Clone the Repository 📁

Clone this repository to your local machine using the command:

git clone https://github.com/RAHB-REALTORS-Association/chat2gpt.git

2. Create Google Cloud Project ☁️

Create a new project in your Google Cloud Console or select an existing one.

3. Create a Service Account and JSON Key 📑

In the Google Cloud Console:

• Head to "IAM & Admin" > "Service Accounts".
• Click "Create Service Account".
• Assign a name and description, then hit "Create and Continue".

• Click "Continue" and then "Done".
• From the list, select the new service account.
• Under the "Keys" tab, choose "Add Key" > "Create new key".
• Opt for "JSON" as the key type and hit "Create". This auto-downloads the JSON key file to your device. This file, containing the service account credentials, facilitates GitHub Actions in deploying your function. Handle with caution.

When assigning roles to your service account:

• For the bot to read/write objects and metadata in the Cloud Storage bucket, grant the "Storage Object Admin" (roles/storage.objectAdmin) role.
• For the GitHub action to create and delete the bucket, grant the "Storage Admin" (roles/storage.admin) role.

👷 Development

The server.py script included in this repository serves as a lightweight, local development server for Chat²GPT. This enables you to test new features, debug issues, or get a firsthand experience of the chatbot's capabilities without deploying it to a production environment. Running the server starts a web service that you can access at http://127.0.0.1:5000.

Setup

The following are only applicable if using the server.py script or Docker:

• Additional environment variables:
  • LOG_FILE: Path to save server log file to. Default: None (disabled)
  • LOG_LEVEL: Enable Flask server debugging mode by setting to DEBUG. Default: INFO
  • HOST: Interfaces to bind server to. Default: 0.0.0.0
  • PORT: Port to bind server to. Default 5000

🧑‍💻 Usage

• Dynamic Interactions: Chat²GPT is attentive to its surroundings. You can invoke it in chat rooms by directly mentioning it using @botname. Alternatively, for more private interactions or queries, you can send a direct message to the bot.

• Interactive Sessions: This bot remembers multiple rounds of a conversation per user, creating an illusion of continuous dialogue. It can even reference past questions or answers, mimicking a natural conversation flow.

• Session Management: To maintain efficient performance, each conversation is limited by a configurable setting, recommended at 5-10 turns. Moreover, the bot keeps an eye on the time since the last message, auto-resetting the session if a set time limit is surpassed. And if needed, users can manually reset their own session anytime with the /reset command.

• Image Generation: Want to visualize an idea? Use the /image <prompt> command. Based on the given prompt, which can range from a word to a paragraph, the bot leverages OpenAI's DALL·E 2 API to generate a relevant image.

• Text-to-Speech (TTS): Utilize the power of Eleven Labs TTS API with the /tts <voice> <prompt> command. This command will return a voice response based on the given prompt in the specified voice. To see a list of available voices, use the /voices command.

• Optimized Performance: We prioritize a smooth experience. Before processing any message, the bot checks its size by counting its tokens. If found too lengthy, an error message suggests the user to condense their message. This ensures uninterrupted bot interactions without straining the system.

• Help On-Demand: Have questions on how to use Chat²GPT? Just type in the /help command. The bot fetches content directly from the docs/usage.md file, ensuring users get accurate, up-to-date information.

Remember, Chat²GPT is flexible, suitable for deployment on Google Cloud, FaaS (Function as a Service), or PaaS (Platform as a Service) environments, ensuring it's a perfect fit for all your Google Chat endeavors.

Commands ⌨️

Use the following commands for Chat²GPT:

• /reset: Reinitialize your session.
• /image <prompt>: Generate an image using OpenAI's DALL·E 2 API.
• /tts <voice> <prompt>: Get a voice response with ElevenLabs' TTS API.
• /voices: View available voices for TTS.
• /help: Access accurate, up-to-date information from the docs.

🛡️ Privacy

Data Practices 📝

• Ephemeral Conversations: Chat²GPT doesn't store or retain conversation history. Every session is temporary, ending when a conversation concludes or times out.

• Temporary Audio Storage: Audio files are stored temporarily in Google Cloud Storage to allow users enough time for downloading. To ensure data privacy and efficient storage utilization, these files are deleted with each app redeployment.

• Reactive Responses: The bot only reacts to direct prompts, such as @mentions or direct messages, and doesn't "read the room".

• Anonymous Sessions: Users are tracked using anonymous ID numbers solely for session consistency. These IDs are cleared with each app redeployment.

AI APIs and User Awareness ℹ️

• OpenAI's Commitment: We use OpenAI's APIs, which, as per OpenAI's policy, don't use user inputs for model training. More details are on OpenAI's official site.

• ElevenLabs' Commitment: We use ElevenLabs' APIs, which, as per ElevenLabs' policy, don't use user inputs for model training. More details are on ElevenLabs' official site).

• User Awareness: Discussing sensitive topics? Exercise caution, especially in group settings. Chat²GPT doesn't log conversations, but your organization or platform might.
