## Key takeaways

- A business chatbot works best on a specific job, such as answering questions from your own documents or helping staff find information.
- It can give wrong answers with confidence, so plan checks, limits and a route to a person.
- The quality of the answers depends on the quality and freshness of the content behind it.
- Decide how you will measure it before you build it.

## What is a business AI chatbot?

It is software that answers questions in natural language, usually using a large language model, and often drawing on your own content such as help pages, product data or internal documents. It can be customer-facing or used by your staff.

## What can it do well?

- answer common questions from documents you give it
- help people find the right page, product or policy
- draft replies for a person to review
- summarise long information
- work outside office hours

These are narrow, checkable jobs. Our guide on [when a business needs AI development](https://www.cognivise.co.uk/blog/when-does-a-business-need-ai-development) covers how to judge fit.

## Where does it go wrong?

- **Wrong answers.** Models can state incorrect things in a confident tone.
- **Out-of-date content.** If your pages are old, the answers will be too.
- **Questions outside its scope.** Without limits, it may try to answer anything.
- **Sensitive requests.** Complaints, payments and personal data need careful handling.
- **Hidden cost.** Ongoing usage, monitoring and content upkeep all take effort.

## What should you plan for?

1. **Scope.** Write down what it may answer and what it must refuse.
2. **Source content.** Decide which documents it uses and who keeps them current.
3. **Handover.** Provide a clear way to reach a person.
4. **Data protection.** If it handles personal data, UK GDPR applies. Check the ICO's guidance on AI and data protection.
5. **Testing.** Try real questions, including awkward ones, before launch.
6. **Review.** Read a sample of conversations regularly.

## How do you connect it to your systems?

A chatbot becomes more useful when it can look up an order or a booking, and that needs an integration with your other systems. See [API integration: what it involves and what can go wrong](https://www.cognivise.co.uk/blog/api-integration-guide). Every connection adds scope, permissions and risk, so start with read-only access.

## How should you measure it?

Agree measures before launch: questions resolved without staff, handover rate, accuracy on a sample, and complaints. Avoid judging it on usage alone.

## Should you build one?

Build when there is a repeated, well-defined task, good content behind it and someone to own it afterwards. Wait when the content is poor, the process is unclear or the risk of a wrong answer is high.
