How much does an AI agent cost to build?
Short answer: most AI agents we build cost between $5,000 and $100,000. A chat agent that answers questions from your own documents sits at the low end. A product with AI inside, web and mobile apps, and five systems to connect to sits at the top, and sometimes above it.

What the AI has to do
Answering questions in a chat is the simplest job. Reading contracts or forms and writing a reply takes more work, because the output must be checked against rules. A phone agent adds speech in and speech out, and it has to be fast enough that a caller doesn't notice the gap.
How many systems it connects to
An agent that only reads your website is quick to build. Each system it must read from or write to (a CRM, a booking calendar, a payment gateway, an ERP) adds testing, error handling and security work. In our projects this is often the biggest part of the cost, not the AI itself.
Volume and running cost
More conversations means more care with speed, caching and model cost. We set it up so the monthly AI bill stays predictable, and we show you that number before we start.
A person in the loop
We usually recommend that a person approves anything that leaves the building: a price, a contract change, a refund. It costs a little more to build, and it is why our clients trust the agent in the first place.
Real examples from our work
- Ask Ira: an AI lending advisor that turns a chat into a draft term sheet for LendVent
- PigeonM: an AI voice and chat agent for a US internet provider
- Indigo e-Sign: AI contract review inside an e-signature product
- InterpreterPro: AI-built practice sessions for court and medical interpreters
You can read how each one was built in our case studies.
Questions
Is the calculator price final?
No. It is a range for planning. We give a fixed quote after a call, once we know your data, your systems and how many people will use the agent.
What does it cost to run every month?
Two parts: the AI model usage (usually tens to a few hundred dollars a month for a small business) and hosting. We estimate both with you before the build.
Can we start small?
Yes, and we usually suggest it: one agent, one job, one system, live in a few weeks. Then add more once it has proved itself.
