One of the most exciting developments in artificial intelligence over the past year is the emergence of natural language processing (NLP) models such as GPT-3 and GPT-4 by the OpenAI.

Companies are continuously seeking ways to enhance their operations and consumer experiences in a world where technology is constantly changing. According to a ResumeBuilder survey in the USA, 49% of companies currently use ChatGPT, and 93% of them plan to increase their use of chatbots. The popularity of ChatGPT, coupled with the right marketing strategy, has more than doubled the value of OpenAI in less than two years! In 2021, OpenAI was valued at $14 billion and is now valued at over $29 billion.

With the help of the OpenAI API, developers may leverage the GPT-3 and GPT-4 models to create SaaS solutions that enhance user experience, automate specific tasks, and boost productivity.

In this article, we'll examine the benefits and challenges of the ChatGPT API in more detail and demonstrate how you can use ChatGPT to improve your SaaS apps. We'll also go through how to integrate the ChatGPT API correctly. Let's start!


❓What is GPT-3 (& GPT-4)?

GPT-3 and GPT-4 are text generation models developed by OpenAI. GPT stands for "Generative Pre-trained Transformer," meaning that GPT models are based on the Transformer architecture and are pre-trained on huge amounts of text data to learn how to generate texts based on given contexts.

GPT-3 is a text generation model that was released in 2020. It has an enormous scope and depth, with 175 billion parameters, making it one of the most advanced text generation models in the world. GPT-3 can perform many tasks related to natural language processing, such as text generation, question answering, translation, text editing, and more.

In November 2022, OpenAI introduced ChatGPT. This chatbot was developed based on GPT3 (and other latest models). While GPT-3 excels at a variety of natural language processing tasks, ChatGPT has been specifically designed for interactive and dynamic conversations, with an emphasis on natural communication.

GPT-3 was trained on an enormous amount of text data, including books, articles, and websites.

In fact, GPT-3 was trained on a dataset containing over 570 gigabytes of text data, which is equivalent to about 60,000 copies of the complete works of Shakespeare!

In March 2022, the new ChatGPT-4 language model was released. OpenAI, at the time of the announcement, wrote on its blog that "GPT-4 is more reliable, creative, and capable of handling much more subtle instructions than GPT-3." Currently, access to ChatGPT-4 is only available through a paid subscription to ChatGPT PLUS, and access to the API is provided through a waitlist, which can be found here.


❔What is the OpenAI API?

The OpenAI API is a platform that provides access to several AI models and tools developed by OpenAI.

The OpenAI API includes numerous machine learning models, such as models for natural language processing, image processing, music generation, and other kinds of data. All these models are pre-trained on large amounts of data and can be used to create applications related to the processing of various data.

Thanks to the OpenAI API, you can access:

  • Model of natural language processing GPT-3 (GPT-4) - creating chatbots, auto texts, generating content, translating text, and much more.
  • DALL-E Image Processing Model (images based on text descriptions).
  • MuseNet Sound Processing Model (music generation based on given parameters).

📈 How can ChatGPT Improve a SaaS Application?

There are several ways to use ChatGPT to enhance a SaaS application. Let's take a closer look at them.

📝 AI Copywriting for Product Pages

This is one of the most popular use cases for ChatGPT. The language model can be used to create product descriptions, headlines, and other marketing materials. In addition to saving copywriter costs in your company, it’ll significantly speed up the process of filling out the product page.

For example, Alibaba has been using an AI-based tool since 2018 to create commercial product descriptions.

📧 Email Generation

ChatGPT can also be used to generate automated emails such as welcome emails, billing notifications, and acquisition/retention emails. By automating these processes, businesses can save time and ensure that their customers receive timely and personalized information.

🤖 Automated Customer Experience Service

ChatGPT can also be used to build automated customer service chatbots. By training the language model on a company's frequently asked questions (you can submit a PDF of your FAQ for this), it can generate responses to customer queries, providing a faster and more efficient service.

You will be able to process numerous requests at the same time without hiring additional employees for customer support.

To protect customers' privacy and give transparency about how their data is used, it is crucial for organizations to make sure their AI customer experience service is planned and deployed in this manner.

Businesses can instantly assist clients with the use of AI, which can enhance client happiness and loyalty.

📊 Data Analysis and Normalization

GPT-3 is a great tool for SaaS startups that don't have access to data analytics expertise. Automatic analysis of unstructured data, viewing and summarizing data, analyzing text in tables - all this is possible with GPT-3. The model can identify relevant objects and concepts in the data, use natural language processing techniques to extract information and generate summaries and reports. Rapid trending, identifying customer segments, and identifying customer preferences are all available with GPT-3.

The model can also be used to create tables based on text and fill in missing information. It's an inexpensive way to increase efficiency and make better business decisions.

🔍 Semantic Search for your Products/Articles

Semantic search uses natural language processing to understand the relationship between words and provide better answers to queries. GPT-3 provides a high level of semantic search functionality that surpasses modern search engines. Semantic search can be used to curate archived business intelligence data, monitor news sources, analyze audio and video data, and solve complex technical issues that can't be resolved with a simple Google search.

🌐 Translate your Product Pages

With this tool, users can easily translate content from one language to another in a few simple steps. The user enters content to be translated, selects the target language and the GPT-3 engine automatically generates the translation in a fraction of a second. This translation feature can be used by SaaS companies to translate content such as contracts, web pages, articles, blog posts, e-books, and press releases for global distribution.

How (and Why) to Integrate ChatGPT into Your Mobile or Web Product


📲 How to Integrate the ChatGPT API

When it comes to integrating ChatGPT into your project, you have a multitude of options. The approach you choose depends on factors such as your current solution architecture, the time and resources you can allocate, and ultimately, the end goal you wish to achieve. It can also be integrated into your organization or communication tools to automize daily basics tasks.

Before integrating ChatGPT, you need to create an account and go to OpenAI platform to create API key. It’s shown only once, so make sure you save it in a safe place and can access it later. Also, keep in mind that you will probably need to configure a billing since the free usage is quite limited.

If you want to add ChatGPT to your current work tools with minimum effort, it can be a great option to use Zapier. Zapier is a popular automation tool that offers convenience and versatility in integrating various applications and services. It enables users to create "Zaps," which are automated workflows connecting different apps, without the need for coding or complex technical knowledge.

Using Zapier, we can easily integrate ChatGPT into your Gmail. Follow the link or create 2 triggers: a new email in Gmail and a conversation in ChatGPT:

With the help of Zapier, integrating ChatGPT into your Gmail becomes a seamless process.

The first trigger is a new email in Gmail.

Connect your Gmail account - give necessary permissions to Gmail for Zapier. You also need to connect ChatGPT using API key we created earlier. You can do both actions inside Zapier triggers. Once you are ready, test it and publish it when all tests are passed. Now you can make the most of its benefits!

Or for example, you need to find specific information in dozens of files, analyze it and provide detailed feedback. This is the case that can be easily achieved using Zapier workflow.

If you want more control, it’s better to use your own service with ChatGPT integration. We’ll also use ChatGPT as an email assistant. This is an example of how to start a conversation:

This is the response we get:

Once you have a new user message, you need to append messages list with a new entity:

and repeat the request.

There can be 3 roles: system, user and assistant in messages.

  • System - the system role is used to provide high-level instructions or context to guide the assistant's behavior. For example, you can set the system message to instruct the assistant to speak like Shakespeare or to adopt a specific persona. The system message helps to establish the overall behavior and tone of the conversation.
  • User - the user role represents the input or message from the end-user or the person interacting with the assistant. It can be a question, command, or any text-based input from the user. The user's message drives the conversation and serves as the primary interaction with the assistant.
  • Assistant - the assistant role represents the model's response to the user's message. It processes the user's input and generates a relevant response based on the context provided by the conversation history - this is ChatGPT itself.

If you want ChatGPT to answer respectfully to previous messages, it’s vital to keep all received and sent messages during the user session in the memory and send them in a messages parameter. Pay attention that with each request, this messages list length will be increased, which means the number of tokens will increase also. It’s leading to more costs spent.
