ChatGPT / BARD API - Build a FREE Chatbot in Python w/ Google Colab

By Analytics Vidhya     Updated Feb 27, 2024

Dive into the world of chatbots with our guide to creating your own using the BARD API and Python, all within the user-friendly environment of Google Colab. No hefty subscription fees - just pure learning and experimentation.

1. Getting Started with Google Colab

The delightful journey to creating your chatbot begins with setting up Google Colab, a beginner-friendly Integrated Development Environment (IDE) that runs in your browser.

The beauty of Google Colab lies in its simplicity and accessibility. You can write and execute Python code, save and share your analyses, and access powerful computing resources, all for free.

To complement your toolset, you'll need the BARD and ChatGPT API keys, which we'll delve into obtaining later in the guide.

2. Building the Foundation: Simple BARD-Powered Chatbot

Our first milestone is crafting a simple yet compelling chatbot using the BARD API. We kick things off by installing the necessary Python packages and setting up environment parameters for BARD access.

Next, we carefully guide you through obtaining a '__Secure-1PSID' from your browser cookies – a crucial step for Bard API access. Following security best practices is paramount throughout this process.

Whether you're an eager learner or a seasoned pro wanting to experiment, our simple chatbot lays the groundwork. You'll learn to send queries and receive responses right within your Jupyter notebook environment.

3. Elevating the Game: Custom Text Summarization Chatbot

After acquainting ourselves with the basics, it's time to tackle a more advanced construct – a chatbot customized for the specific use case of text summarization.

By employing the power of the BARD API for text summarization, you'll learn to digest PDFs – from classic texts to scholarly papers – into concise summaries, a skill that has numerous practical applications.

This segment of the tutorial is not just instructive but interactive, encouraging you to blend code, creativity, and problem-solving to forge an efficient text summarizing bot.

4. ChatGPT API: Expanding Horizons beyond BARD

The allure of ChatGPT isn't overlooked, as we also discuss how to imbue your chatbot with the sophistication of the ChatGPT API for text summarization tasks.

While BARD is our primary focus, due to its free access for learning, we acknowledge the enhanced capabilities of ChatGPT. We provide code snippets for those with access to the OpenAI platform.

Encouraging comparative learning, we juxtapose the BARD and ChatGPT APIs, drawing insights into their unique strengths and how they can be leveraged for custom chatbot solutions.

5. Troubleshooting Common Hiccups

Diving into the experiencer's shared issues offers invaluable insights. Errors such as an undefined 'pdfFileObject' or elusive 'SNlM0e' value are typical stumbling blocks when crafting your chatbot in Google Colab.

These comments reflect the trial and error process essential in navigating technical journeys. By dissecting these stumbling blocks, you'll gain problem-solving acumen that's transferable beyond making chatbots.

Heed the advice of your fellow coders in the comments. Avoid generic background music that distracts from the content, experiment with different strategies for managing text, and share your successes (or setbacks) for collective growth.

6. Understanding the Ethical Use of APIs

One critical discussion points to the appropriate usage of Bard API, cautioning against unofficial methods to access it as they may be impractical or frowned upon.

It's essential to approach the creation and usage of APIs with legality and ethics in mind. The Bard API, while in beta, should ideally be accessed through the Google Cloud Platform console.

The comments echo a significant sentiment: while the eagerness to innovate is commendable, it's equally important to employ methods that are respectful of the technology and its creators.

7. Customizing and Advancing Your Chatbot

A lively discussion unfolds around customization, unveiling possibilities like tailoring your chatbot to niche topics such as agriculture or specific language support.

Enthusiasts express curiosity about advancing bot functionality, questioning access to features like 'input image' or fine-tuning within BARD's free version.

The exchange of ideas and concerns in the comment section is a goldmine for anyone looking to stretch the boundaries of their chatbot's abilities and adapt to diverse needs.


This rich tutorial guides you through the exhilarating process of building your very own chatbot. You'll be using Python powered by BARD API, which is perfect for beginners and free for learning purposes. From setting up your environment to constructing a sophisticated chatbot for custom scenarios, this article covers all bases. You'll even see how to employ Google Colab for your project, complete with tips on API keys and a use case involving text summarization.
