How to Build a Custom AI Chatbot
Discover the step-by-step process of building a Custom AI Chatbot that truly fits your business. Learn what it takes, from content prep to tuning and deployment—plus how Nevolis makes it easier.
Now that we’ve covered what a Custom AI Chatbot is and why it’s worth the investment, let’s talk about how one is actually built.
While modern tools make chatbot creation more accessible than ever, building one that uses your data and follows your business rules still requires careful planning—and expert support can save you time and costly missteps.
Step 1: Define the Goal
Before anything else, clarify what you want your chatbot to do.
- Answer FAQs?
- Check order status?
- Book appointments?
- Guide new users?
This will shape the rest of the build process.
Step 2: Gather Your Content
Your chatbot learns from what you feed it. This could include:
- Help articles
- Product catalogs
- Company policies
- Internal SOPs
- Customer emails or support logs
All these become part of the chatbot’s “brain.” Nevolis can assist in organizing and structuring this information for better AI understanding.
Step 3: Set the Rules
Even smart chatbots need guidance. Define how it should behave:
- What’s the greeting message?
- When should it hand off to a human?
- What tone or language should it use?
- Should it ask follow-up questions?
This is where you set the flow and boundaries. We can help translate business rules into a functional and intuitive conversation design.
Step 4: Choose the Right Tools
To make everything work, you need the right setup. That includes:
- AI Engine: Like OpenAI, Google, Deepseek, or other LLMs
- Retrieval System (RAG): For pulling info from your content in real time
- Frontend Widget: To place the chatbot on your website or app
- Integration Layer: To connect with your database, CRM, or booking tools
- Multi-Channel API: To deploy your chatbot on WhatsApp, Telegram, Facebook Messenger, email, or even SMS—all from the same system. This multi-channel integration ensures your chatbot can reach users wherever they are, offering consistent help across platforms. Nevolis helps handle all of these layers—from selecting the best tools to integrating and tuning them into your operations.
- Tuning Parameters: Like chunk size, overlap, temperature, top-p, top-k, and memory buffer, which all influence how your chatbot understands and responds to user input. These parameters are critical to finding the right balance between creativity, accuracy, and efficiency. Nevolis helps fine-tune all of this based on your goals and the nature of your content.
Step 5: Test, Improve, Repeat
No chatbot is perfect from day one. Track real conversations, spot where users get stuck, and improve:
- Add missing answers
- Adjust the flow
- Update content
- Improve clarity or tone
- Refine tuning settings based on real-world usage
This step never truly ends—and that’s a good thing. Your chatbot grows with your business. At Nevolis, we support long-term improvement to ensure your bot stays relevant and helpful.
