# Build a custom AI agent yourself

Drag the steps, connect them, replay against real data, then ship. It runs in your browser and you don't need an engineer.

[Start free](https://certant.ai/register) See the templates

Drag and drop, with a code step when you need one.

Example

Drag a step from the library, drop it on the canvas, ship the run.

In one sentence

A custom AI agent is a workflow you _design_: which documents it reads, what rules it follows, which tools it calls, when it stops for a human.

Off-the-shelf chatbots don't know your policy book. Custom-coded agents take a quarter and a senior engineer. Certant gives you your knowledge and your rules on a visual canvas.

How to build it

## Five steps, start to production

What happens between wanting an agent and running one.

1. **Upload** Point Certant at the documents or systems the agent needs to know. Certant reads them and builds the map.
2. **Pick a template** Approval bot, Triage bot or Research bot. Start from one, change anything.
3. **Set the rules** "Escalate anything over the limit you set." "Always cite the source." "Pause when it isn't sure." Written in plain English.
4. **Replay** Run the agent over data you already have. See every step, and compare it against the previous version.
5. **Ship** One click. Every version is kept and you can roll back. Our cloud, or inside your own walls.

Three starter templates

## Pick the closest template

Each one is fully editable. The shape is the same; what changes is what it decides.

Approve

### Approval bot

Reads each incoming item (a contract, a leave request, a purchase), checks it against your policy, and either approves it, redrafts it, or hands it to a human with a citation.

- Best for legal, finance, HR
- Decision rules in plain English
- A person decides when it's unclear

Route

### Triage bot

Watches an inbox, ticket queue or webhook. Classifies the topic and urgency, routes to the right team, drafts a first response with a citation, and updates the system of record.

- Best for support, member services, IT
- Puts a first reply in the queue straight away
- Routes by topic, language and value

Research

### Research bot

Given a question, reads a set of documents you choose (your policy library, your case files, a specific archive) and returns a structured answer with citations. Same agent, different question every day.

- Best for analysts, advisors, knowledge work
- Returns a structured record or a written brief
- Always cites the source paragraph

Vs hiring a developer

## What this costs against hiring

You can hire someone to build this, or you can build it yourself this week.

Hire a developer

### A senior hire and a quarter of ramp-up.

A senior AI engineer, a backend engineer, and a quarter of integration work. Then the same conversation next year when the policy changes.

Build it on Certant

### One platform, and the person who owns the process owns the agent.

Build as many agents as you need. The non-engineer on your team owns them, and your engineers go back to the harder problems. See [pricing](https://certant.ai/pricing).

FAQ

## What buyers ask

The questions teams ask before they start building.

Do I need to know how to code to build an AI agent?

No, most workflows are built visually: drag a node, connect it, configure it. You can drop in code for the cases that need it: custom logic, or calling an internal system nothing else reaches.

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

Most teams have a first useful agent working in one sitting. A production rollout with integrations and approvals takes a few weeks.

What templates are available?

Approval bot (review and approve incoming items against your policy), Triage bot (classify and route incoming work), Research bot (read a document set you choose and produce a structured answer). Each one is fully editable.

How much does it cost vs hiring a developer?

Cheaper than a senior AI engineer, and you don't wait for a hire. Pricing is credit-based and published on the [pricing page](https://certant.ai/pricing).

Can I drop in code if I need to?

Yes. Any node can be a Python or JavaScript snippet. You keep the canvas, and you can still drop to code when you need to.

Can I try it without installing anything?

Yes. Sign up free, upload a document set, and build the first agent in the browser. Nothing to install.

## Stop waiting on IT. Build the agent.

Free to try, nothing to install, and it runs in your browser.

In one line

If your team can draw the process on a whiteboard, they can build the agent. The whiteboard is the spec.
