How Your Custom AI Agent Works

JOURNEY 1

The agent resolves it, end to end

A customer asks

The journey completes

Booked, applied, enrolled or checked out. Every action logged.

AI Helpdesk Without the Extra Fees

What a licensed desk charges

Intercom, now Fin

$29 to $132 per seat

Plus $0.99 each time Fin resolves a conversation alone.

Zendesk

$19 to $115 per agent

Plus $50 per agent for Copilot, and a metered AI rate reported near $1.50 to $2.00.

Gorgias

$10 to $750 by ticket volume

Plus $0.90 per AI resolution, which also counts as a billable ticket.

Published list pricing on annual billing, checked August 2026.

What you pay us for it

Per seat. Put your whole team on it.

Per resolution. Volume costs you nothing.

Inbox, tickets, routing, macros and CSAT, built as part of the agent and yours like the rest of it.

Already on Zendesk, Intercom, Gorgias, Freshdesk or HubSpot? Keep it. The agent sits in front and files what it should not answer as a normal ticket, so macros, SLAs and reporting stay as they are. Talk through both routes →

FAQ

Custom AI Agent FAQs

What exactly is a custom AI agent?

A conversational system built for one business, on that business’s own knowledge, rules, tone and connected systems, running under its own model keys. Its behaviour is defined during the build, not configured inside a vendor’s product.

Can I ask for something specific instead of a package?

That is how every build starts. You describe the outcome, we scope what it takes in writing, and you get one fixed quote against that scope before anything is built.

Which models and providers can it use?

Closed-weight models such as Claude, GPT, Gemini and Mistral, and open-weight models such as DeepSeek, Kimi, MiniMax, Qwen and Llama. They can run on AWS Bedrock, Google Vertex AI, Azure AI Foundry, OpenRouter, direct provider APIs, or your own GPUs. You hold the account and keys, and models can be swapped without rebuilding the agent.

Which channels does it work on?

Customers reach it on your website or app, WhatsApp, Telegram, Microsoft Teams, Slack and Discord. Messenger, Instagram DM, email, SMS and voice are scoped on request. One agent, one knowledge base, no per-channel licence.

What does it cost, and how long does it take?

Scope drives cost. Discovery and solution design is $999 flat and produces a written design plus a fixed build quote, credited toward the build. Industry ranges for custom builds run from roughly $15,000 to over $150,000. Scoping takes two weeks, most builds go live 6 to 10 weeks after that, and the demo is free.

Will it make things up?

It answers only from knowledge you approve and systems you connect. When it cannot, it asks one of your people rather than guessing, and the customer sees a reply a human signed off.

Do I own what you build?

Yes. The build, prompts, workflows, integrations and data are yours, documented and handed over. It can also honour login, membership and entitlement rules, so gated knowledge stays gated.

When are you the wrong choice?

If you need it live next week, if you want the cheapest option, if your knowledge is one FAQ page, if nobody on your side will take the pings or approve what the agent may say, or if you want AI to replace your support team outright.
