## Questions

### Should I add a standalone chatbot or use my help desk's AI?

A standalone agent such as Chatbase is quick to add to any site and has a free plan to start. Help desk AI, such as Intercom's Fin, sits inside the inbox your team already uses, so handovers keep the full conversation. Crisp and Help Scout also pair AI with a shared inbox for small teams. Pick standalone if you have no help desk yet, and built-in if you do.

### What content should I train the agent on first?

Start with your twenty most common questions and write a clear help article for each. Chatbase learns from your website, help articles and files, and Help Scout's AI drafts answers from your own articles. Leave out old pricing pages and outdated policies, since the agent will quote them. Review the questions it fails on each week and add an article for each gap.

### Can the bot do things, or only answer questions?

Chatbase agents can take actions, such as making a booking or looking up an order. Intercom's Fin answers from your support content and hands over to a person when it cannot help. Start with read-only lookups before you let a bot change anything for a customer. Refunds and account changes are safer with a human approving them.

### How much does an AI support agent cost for a small shop?

Chatbase, Crisp and Help Scout each list a free plan, so you can test an agent at no cost. Intercom has no free tier, and its cheapest seat is $29 a month. Crisp prices per workspace, which keeps costs flat as you add people. Compare the price against the hours your team spends on repeat questions each month.

### How do I stop the AI from making things up?

Keep the agent tied to your own content, which is how Chatbase and Fin are built to work. Tell it to hand over when it is unsure, and make the route to a person visible in the chat. Test it with awkward questions before launch, including ones about prices and refunds. Under the EU AI Act, tell customers they are chatting with an AI.
