How much does an AI chatbot or AI agent cost to build?
Short answer
Custom AI builds at AtomikEngine are fixed-scope: AI Essentials $5,000 for a lead assistant plus one workflow, AI Automation $10,000 for up to five workflows and internal assistants, AI Business Platform $20,000 for custom models and an operations layer, and Enterprise AI from $50,000 for bespoke AI infrastructure. Model usage and hosting are billed separately at cost.

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.
