How much does an AI chatbot or AI agent cost to build?
Short answer
Custom AI builds at AtomikEngine start at $2,500 for a starter chatbot, $7,500 for a professional agent with retrieval over your own documents and CRM integration, $15,000 for multi-agent workflows, and $25,000+ for an enterprise AI platform. Model usage and hosting are billed separately.

What changes the price
How much private knowledge the agent needs (a pricing page versus a document library), how many systems it writes to, whether it needs human handoff, and how strict the evaluation and guardrail requirements are.
Ongoing costs are model tokens, vector storage where used, and optional managed monitoring. These are usage-based and disclosed before build.
What a chatbot is genuinely good at
Answering repetitive pre-sales questions instantly, qualifying and routing leads into your CRM at any hour, and deflecting support volume. It is not a replacement for a sales team — it is the first response that keeps a lead warm.
