AI chatbots are no longer a novelty. In 2025, they are becoming a practical tool for SMEs that want to improve support, reduce repetitive enquiries and offer smarter self-service without hiring extra staff. The good news is you don’t need to rebuild your web app from scratch to benefit — you can add an AI chatbot to an existing system.

This guide explains where chatbots make sense, how to integrate them into your current web app and what to watch out for along the way.

Where AI Chatbots Actually Add Value for SMEs

There is a lot of hype around AI, but the use cases that work best for SMEs tend to be simple and focused. Common examples include:

Answering frequently asked questions about services, processes or pricing
Helping users navigate your web app (“Where do I find my invoices?”)
Providing basic technical support (“How do I reset my password?”)
Explaining documents or reports in plain English
Guiding staff through internal workflows or compliance steps

Think of AI chatbots as smart, always-available assistants that deal with repetitive questions — not as a replacement for your staff.

Types of AI Chatbots You Can Add

For SME web apps, there are three main styles of chatbot integration:

1. Website Support Chatbots

These appear as a chat bubble on your website and handle:

Pre-sales questions
Service explanations
Basic onboarding help

They can be trained on your website content, FAQs and documentation.

2. In-App Help Assistants

These live inside your existing web app (for logged-in users) and provide:

Context-aware help (“Explain this screen”)
Guidance on next steps in a workflow
Inline help for complex pages

They are particularly useful for staff-facing systems with complex functionality.

3. Domain-Specific Knowledge Bots

These are trained on:

Your internal documentation
Standards and regulations
Technical manuals

They allow staff (or sometimes customers) to ask detailed questions about a specific topic and get helpful summaries.

How AI Chatbots Work Under the Hood (High Level)

Most modern chatbots follow a simple pattern:

User asks a question in the web UI.
The app sends the question (and optional context) to an AI API.
The AI generates a response based on your content and rules.
The web app displays the answer and logs the conversation.

Underneath, you can use:

Large language model APIs (e.g. OpenAI or similar services)
A vector database to store and search your documents
Custom prompts that keep the bot aligned with your business

Integrating an AI Chatbot Into an Existing .NET Web App

If your app is already built with .NET Core and Razor Pages, you can integrate a chatbot without major changes. A typical setup might include:

A chat endpoint in your .NET backend that talks to the AI API
A JavaScript-based chat UI on your pages (a simple widget or panel)
A data store for conversation history, feedback and analytics
A document ingestion process if you’re building a knowledge-based chatbot

The chatbot becomes just another feature of your application.

Key Design Decisions

1. Who Is the Chatbot For?

Decide whether you are building a bot for:

Public website visitors
Existing customers inside a portal
Your own staff

The audience determines tone, permissions and content sources.

2. What Should It Be Allowed to Answer?

Define the scope clearly:

Only FAQs and public information?
Account-specific queries (e.g. “What is my balance?”) that require authentication?
Internal process and policy questions?

Well-defined boundaries make the chatbot more predictable and safer.

3. What Content Will It Use?

AI chatbots need high-quality content. You can feed them:

Website copy and blog posts
Help articles and manuals
Internal process documentation
Structured data from your database

Good inputs lead to good answers.

Handling Safety, Tone and Accuracy

A good SME chatbot should feel:

Helpful and concise
On-brand in tone
Clear about its limitations

Best practices include:

Explicit instructions to keep responses factual and relevant
Fallback messages when the bot is uncertain
Links to contact a human when needed
Logging and reviewing queries to improve prompts and content

Where AI Chatbots Can Go Wrong

AI is powerful, but not magic. Common pitfalls include:

Over-promising: positioning the bot as a human replacement
Under-training: not providing enough business-specific content
No guardrails: allowing the bot to guess about legal, medical or financial matters
No human escape hatch: users getting stuck with unhelpful answers

Good design and testing prevent most of these problems.

Practical Steps to Add a Chatbot to Your App

Define the use case (support, navigation, internal help, etc.).
Gather and clean your content (FAQs, docs, guides).
Choose your AI provider and integration approach.
Build a simple chat UI into your existing web app.
Create a backend endpoint to talk to the AI API.
Test extensively with real-world questions.
Monitor, log and refine based on actual usage.

Start small and iterate — you don’t need a perfect chatbot on day one.
