Custom AI Development

Custom AI Development
Agents, Chatbots, and Workflows You Own

Anar Agency is a custom AI development company for businesses with 10 to 500 people. We build AI agents, chatbots and assistants, and workflow automations on top of the major models, connected to your data, with guardrails, quality tests, and spend caps. Delivery is 60 to 120 days for the first phase, $2,000 to $15,000 per month, and you own the accounts, the code, and the documentation.

Off-the-shelf AI tools stop where your data and your rules begin. Custom development starts there.

What we build

AI agents

Software that takes a goal, uses tools like your CRM, calendar, and email, and finishes the job inside limits you set.

Chatbots and assistants

Customer and staff assistants that answer from your real documents and policies, not from the open internet.

Workflow automations

Intake, routing, follow-up, summaries, and reports that run on their own and hand exceptions to a human.

Document workflows

First drafts, summaries, and checklists from your own templates, with a person signing off before anything leaves.

Integrations

The plumbing between the AI and the tools you already pay for: CRM, phones, calendar, billing, spreadsheets.

Evaluation and cost controls

A repeatable test that shows the output is right, and caps that stop a runaway bill.

When custom AI development makes sense

Buy a tool when a tool already does the job. Build custom when one of these is true:

If none of those are true, we will tell you to buy the tool. We say so on the first call; it is cheaper for everyone.

How custom AI development works

01

Scope (two weeks)

We map the workflow, the data it needs, the rules it must follow, and the before number we will measure against.

02

Build and test (30 to 90 days)

We build on the model that fits, connect your data, and write the tests. You see working output in the first month, not at the end.

03

Guard and cap

Guardrails on what the AI can touch, spend limits, and a review step for anything that leaves the building.

04

Hand over

Plain-language documentation, training for a named owner on your team, and the accounts in your name.

The agent patterns we use are the ones described in Anthropic's guide to building effective agents, linked below: simple, composable, and testable before they are clever.

Security and ownership

Every build is checked against the OWASP Top 10 for large language model applications, the industry list of the ways AI systems get attacked, and the review steps follow the NIST AI Risk Management Framework. Three rules never bend:

We keep systems model-agnostic so you can move between Claude, ChatGPT, and Gemini as prices and capabilities change. More on that in our model-agnostic AI strategy guide.

What custom AI development costs

Our engagements run between $2,000 and $15,000 per month, billed monthly, not by the hour. The first phase is 60 to 120 days and you should see a working, measured system inside the first month. Full detail on what moves the price is on our AI implementation services page.

Two things move the price on a custom build: how many systems the AI must connect to, and how much testing the workflow needs before a person can trust it. A chatbot over your documents is the low end. An agent that touches money is the high end.

Running cost is separate and we cap it. The habits are in Controlling AI Token Spend and How to Evaluate AI Agents.

Questions owners ask us

What does a custom AI development company do?

It builds AI software for your specific business: agents, chatbots, and automations connected to your data and tools, with rules and tests, and hands it over so your team can run it. That is different from selling a subscription to a general tool.

How much does custom AI development cost?

Our engagements run $2,000 to $15,000 per month. A chatbot over your own documents sits at the low end. An agent that connects to several systems and touches money sits at the high end. Running costs are capped separately.

How long does it take to build a custom AI agent?

The first working version lands inside the first month. The first phase, where the agent is built, tested, and handed over, takes 60 to 120 days depending on how many systems it connects to.

Do I need my own developers?

No. We build it, document it in plain language, and train one owner on your team. If you later hire a developer, the code and accounts are already yours.

Which AI models do you build on?

Claude, ChatGPT, and Gemini, chosen per workflow. We keep the build model-agnostic so you can switch when prices or capabilities change.

Is a custom chatbot safe to put in front of customers?

Only with rules and tests. Ours answer from your approved documents, refuse what they are not allowed to discuss, and hand off to a person on the topics you name. We test against the OWASP LLM Top 10 before launch.

Who owns the code?

You do. Accounts, code, documentation, and data are in your name when the engagement ends.
