Bard.py

Python Client for Bard, a Chat Based AI tool by Google.

Note

This is an unofficial client.

Features

• Connect to Bard, Google's AI-powered personal assistant.
• Ask questions and have a conversation.
• Improve responses by defining the conversation tone and length.
• Use asyncio for efficient and non-blocking I/O operations.

Requirements

• Python 3.10 or newer
• Google account with access to Bard

Installation

To install Bard.py, run the following command:

pip install bard-py

or, if you use poetry:

poetry add bard-py

Tip

Make sure you're using the latest version of Bard.py to ensure best compatibility with Bard.

Usage

Prerequisites

To use Bard.py you first need to extract the __Secure-1PSID and __Secure-1PSIDTS cookies from the Bard web page. These cookies are used to authenticate your requests to the Bard API.

To get the cookies, follow these steps on Chrome:

• Go to the Bard web page.
• Write a message on the chat dialog that appears.
• Open the developer tools in your browser (usually by pressing F12 or right-clicking on the chat dialog and selecting Inspect).
• Select the Application tab and click on the Cookies option to view all cookies associated with https://bard.google.com.
• Look for the __Secure-1PSID and __Secure-1PSIDTS cookies and click on them to expand their details.
• Copy the values of the cookies (they should look like a long string of letters and numbers).

Then, set them as environment variables in your shell:

export SECURE_1PSID=<your-cookie>
export SECURE_1PSIDTS=<your-other-cookie>

or, in your Python code:

os.environ["SECURE_1PSID"] = "<your-cookie>"
os.environ["SECURE_1PSIDTS"] = "<your-other-cookie>"

Example

You can use Bard.py to easily create a CLI client for Bard:

import asyncio

from bard import BardClient


async def main() -> None:
    async with BardClient() as bard:
        while True:
            prompt = input("You: ")

            if prompt == "!reset":
                await bard.reset_conversation()
                continue
            elif prompt == "!exit":
                break

            response = await bard.ask(prompt)
            print(f"Bard: {response}")


if __name__ == "__main__":
    asyncio.run(main())

Bard Client

You can create a Bard Client and initialize a connection with Bard which starts a conversation:

bard = BardClient()

await bard.start_conversation()

# Conversation

await bard.end_conversation()

Alternatively, you can use the async with statement to keep the code compact:

async with BardClient() as bard:
    # Conversation

Reset Conversation

You can reset the conversation in order to make the client forget the previous conversation:

async with BardClient() as bard:
    # Conversation
    await bard.reset_conversation()

Ask

You can ask Bard questions and get the results:

async with BardClient() as bard:
    response = await bard.ask("When was Bard released?")
    print(response)

Tone

You can set the tone when having a conversation with Bard:

async with BardClient() as bard:
    _ = await bard.ask("When was Bard released?")

    response = await bard.ask("When was Bard released?", tone="Professional")
    print(response)

The available options for the tone parameter are:

• Professional
• Casual

Note

It is recommended to use the tone parameter on subsequent prompts and not in the first one. This is because this feature is typically used to change the previous response, rather than define the entire conversation tone.

Length

You can set the response length when having a conversation with Bard:

async with BardClient() as bard:
    _ = await bard.ask("When was Bard released?")

    response = await bard.ask("When was Bard released?", length="Short")
    print(response)

The available options for the length parameter are:

• Short
• Long

Note

It is recommended to use the length parameter on subsequent prompts and not in the first one. This is because this feature is typically used to change the previous response, rather than define the entire conversation length.

Exceptions

When something goes wrong, Sydney.py might throw one of the following exceptions:

Exception	Meaning	Solution
CreateConversationException	Failed to create conversation	Retry or use new cookies
AskException	Failed to get response from Bard	Retry or use new cookies
NoResponseException	Received an empty response from Bard	Wait and retry
