How do you stop the bot making things up?
Retrieval plus a threshold. The bot answers from your own documents, not from the model's memory, and every answer has to clear a confidence bar before it's shown. Below that bar it says it doesn't know and hands over.
What does an AI chatbot cost to build and run?
The build is one fixed price, quoted after a free 30-minute call. Running costs are model usage, usually $30 to $200 a month depending on volume, and I size that against your real traffic before you commit.
Which model do you use?
The cheapest one that clears your quality bar. Claude for a nuanced support tone, a smaller model for high-volume sorting, open-source and self-hosted if data can't leave your servers. I have no reason to prefer one vendor.
Will my customer data go to an AI provider?
For most builds, yes: that's how the APIs work. Anthropic and OpenAI both offer terms that keep your data out of training, and I set those up. For legal, medical or financial use, I can self-host an open model so nothing leaves your servers.
Can it hand over to my team?
Yes, and I wouldn't build one that couldn't. Handover goes to Slack, your helpdesk or email with the full transcript and customer record attached, so nobody starts from zero.
