As you may already know, artificial intelligence paves the way for business innovation. Nowadays, with increased accessibility and demand, businesses create various AI solutions to improve all sorts of their operations.

One such solution is an AI assistant, which is capable of a lot. At Codica, no trends move past us, so we made our very own AI-powered assistant. Today, we’ll share our experience developing AI solutions, especially an AI assistant. We’ll cover the idea behind it, the benefits it brings, and explain in greater detail how it works.

Why an AI assistant?

Naturally, our expertise is multifaceted, as we provide all sorts of custom development services to our clients. Namely, we are experts in building custom marketplaces, creating MVP, SaaS solutions, and much more. Besides, we employ our expertise in many domains. With such a broad expertise range, categorization and some kind of order is paramount.

Our clients, be they startup founders or well-established business owners, may not have enough time to study through our website if they’re interested in our services. Consequently, bits of important information are left unnoticed, which is bad, both for us and for them.

For this exact reason, our AI assistant has been built. It lets our clients get a breakdown of any of our services, articles, and case studies in a matter of seconds. AI, in turn, makes sure to provide all the necessary information about our expertise, including relevant links, tips, and suggestions. Here’s a neat example:

  • Consistent support. It reduces the frustration of inconsistent information, providing reliable assistance every time. Besides, AI also makes our website more accessible to users with different needs by offering premade text options and multilingual support.

Planning and strategy

When planning the integration of our AI assistant, it was essential to define clear objectives to guide the development process. We identified five key goals that would drive the design and implementation of the AI assistant.

Main goals driving the implementation of AI assistant

1. Reduce response time

One of our primary objectives was to reduce the response time for clients interested in our services. By automating the initial interaction with users, the AI assistant could provide immediate responses to common questions, minimizing the time customers spend waiting for assistance.

2. Automate FAQs

We aimed to automate the handling of frequently asked questions (FAQs), which often constitute a large portion of client inquiries. Therefore, our AI assistant was designed to provide accurate, consistent answers to these questions, freeing up our sales team to focus on more complex issues.

3. Deliver personalized recommendations

To further improve the experience, we wanted the AI assistant to offer personalized recommendations based on clients’ interests. As a result, our assistant can suggest relevant services, case studies, and blog articles to provide more information.

4. Provide a comprehensive overview of our services

We sought to ensure that the AI assistant could provide a thorough overview of all the services we offer. Whether a potential client is exploring our website for the first time or an existing customer is looking for more information, the AI assistant was designed to guide users through our service offerings, answering questions and providing details as needed.

5. Suggest blog articles and case studies

Recognizing the value of content in driving customer engagement, we wanted the AI assistant to suggest relevant blog articles based on clients' questions.

Choosing the right AI technology

Selecting the right AI technology was a critical decision in the planning phase. We needed a solution that was not only powerful and capable of meeting our objectives but also flexible and easy to integrate into our existing tech stack.

Codica AI assistant is based on the large language model (LLM). While traditional LLMs work by processing input text and generating output text, the chat model goes further by processing messages. These messages consist of content and roles that indicate the author, whether a human, AI, or system.

Regarding the details, we decided to use GPT-4o-mini, which is a version of the GPT model developed by OpenAI. This model specifically offers robust conversational capabilities, allowing the assistant to understand a variety of user requests and respond to them efficiently.

Besides, an assistant was designed with scalability in mind, allowing us to expand its capabilities as our company grows and needs change.

How it works

Moving from the theory, let’s see how everything coherently works together to deliver what is known as an AI assistant.

First of all, Codica AI assistant works on the principle of LangChain. This concept combines external data sources and computation with a Large Language Model. This allows to create logical sequences of operations, known as chains, that guide the assistant's behavior. Therefore, it uses a series of organized steps, including:

  • Input data processing;
  • Vector embedding generation;
  • Semantic search;
  • Contextualization;
  • Answer generation.

As a result, Codica AI assistant provides intelligent and contextually relevant answers to user queries. With the LangChain concept, the assistant combines multiple operations into coherent sequences, enriching its conversational capabilities and increasing user engagement.

Apart from the general work process, there are several aspects that are important to look into.

Prompts set up

For starters, let’s see what the prompt actually is. Basically, the prompt is a list of instructions you give to the model. It is a set of inputs that can help the model understand the context of your question.

Next, after understanding the question itself, the model can generate relevant and coherent outputs, such as answers to questions. Prompts can include rules, instructions, small examples, as well as specific context and questions appropriate for a particular task.

Yet, you may wonder why our model doesn’t answer unrelated questions. Say, if you ask it something out of the scope of our expertise at Codica, it will respond with a predetermined “Sorry, I don't know how to help you with this.”

Basically, it is programmed to do so. At Codica, we developed a basic template for an AI assistant, allowing it to know which questions are relevant and which ones are not. This way, our AI assistant provides comprehensive information only on matters we are experienced with.

After all, it works reasonably simply. The model remembers our template instructions, and after receiving input from the user, it produces an answer that addresses the question and makes sure the conversation is relevant.

Memory

An important part of all conversations with AI is the ability of the latter to “remember”. Essentially, it refers to information presented earlier. This feature allows AI to maintain context throughout the conversation, remember previous interactions, and provide more relevant and consistent responses.

Response generation

To provide actual valid information, AI has a specific way to gather and preprocess the data.

It utilizes web page and document loaders, which are services that can pull information from our blog, case studies, and service pages to provide a response. Here’s a short summary:

  • Purpose. Document and web page loaders are used to import and process data from static text files, and online sources, such as websites or web pages.
  • Functionality. They crawl or fetch web pages, extract the content (usually text and sometimes metadata), and convert this content into vector embeddings. The processed data is then stored in the vector store for retrieval.
  • Use case. Our AI assistant needs to provide up-to-date information from our company’s blog, service pages, and case studies. Therefore, these services provide access to content for AI.

With both loaders, the AI assistant can access a broad range of information, from documents to the latest web content, enhancing its ability to provide accurate and comprehensive answers to user queries.

Working with data

To extend its capabilities beyond its training dataset, Codica AI Assistant uses Retrieval Augmented Generation (RAG). This methodology includes a retrieval component that extracts external data that is then used during answer generation.

RAG allows our AI assistant to access and use information beyond its pre-existing training data. But why do you need it in your chatbot in the first place?

Well, most AI models, especially those focused on natural language processing (NLP), are trained on a fixed dataset that includes a vast amount of text data. However, this dataset has limits — it may not include the latest information, specific domain knowledge, or context-specific data that users might ask about. This can restrict the AI's ability to generate accurate and up-to-date responses.

RAG exists to address this exact issue. It works fairly simply, using two main components:

Retrieval component

RAG incorporates a retrieval mechanism that allows the AI to search for and retrieve relevant information from external sources like the web, databases, and various types of documents. This component acts like a search engine within the AI system, pulling in data that the model can use to enhance its responses.

Here, the retriever is the component responsible for searching and retrieving relevant information based on a query. It uses data stored in the vector store to find the best matches for the query.

In the vector store, the data is stored in the form of vector embeddings. The retriever accesses this store to retrieve the most relevant vectors (data) that match the query.

Generation component

Once the relevant data is retrieved, it is fed into the AI's generative model, which uses this external information to formulate a more accurate, context-aware answer. Essentially, the AI combines what it "knows" from its training with the newly retrieved data to generate a response.

The entire process explained

Once all important aspects are covered, let’s zoom out a bit and take a look at how the entire chain of commands works.

AI assistant workflow made by Codica

1. User input and initial processing

At the start, the user enters a query or data into the system. This input data is converted into vector embeddings, representing the semantic meaning of the user’s request.

2. Retrieval of relevant data

The retriever performs a semantic search using vector embeddings to find relevant data that closely matches the user's query. Next, it extracts the most relevant information from the vector database. This data often includes company articles, case studies, and service pages that were not part of the initial LLM training.

3. Context formation

The retrieved data forms the context that the model will use for further analysis. This context is crucial for generating accurate and relevant responses.

4. Chat history management

In our case, the chat history is stored in Redis memory (used for data storage), which helps maintain the continuity of the conversation by remembering previous interactions. During the next interactions, the system extracts the chat history from Redis to provide context for the ongoing conversation.

5. Prompt construction

The system combines several elements to construct a prompt. They include instructions and rules for the model, user data, chat history, and any additional retrieved context. This prompt serves as the basis for creating a query for the model.

6. Query submission

The constructed query is sent to the OpenAI API.

7. Response generation

The OpenAI model processes the query and generates a response that revolves around the context and the prompt given.

8. Response handling and continuous interaction

Once the answer is received, the generated response can be immediately delivered to the user. Alternatively, the response can be passed to an output parser. The parser, in turn, converts the response into the required format (e.g., JSON or CSV) before delivering it to the user.

The AI assistant continues to interact with the user, maintaining context through Redis memory and adapting responses based on ongoing input. This sequence ensures that the AI assistant can efficiently process user queries, retrieve relevant information, and generate contextually accurate responses, all while maintaining a continuous and coherent interaction.
