## What is Athena AI?

**Athena AI** — a platform for creating AI agents that communicate with customers instead of a manager: they answer questions, collect leads, book services, and hand off complex conversations to a human. All conversations from messengers and the website are in one window.

AI agents for sales, support, HR, and operations. CRM integration. **No code.**

The agents use modern LLM models and your knowledge base to provide accurate and personalized answers — from simple FAQs to multi-step sales and booking scenarios.

### How it works

```
1. Connect channels          →  Telegram, WhatsApp*, MAX, website, social networks
2. Train the AI agent          →  role, instructions, knowledge base — in plain language
3. Connect CRM             →  amoCRM, Bitrix24, HubSpot, GetCourse
4. Scale              →  new channels, agents, and scenarios without development
```

**NPI (Natural Prompt Interface)** — Athena's technology: you describe the business and the agent's behavior in plain text, and the platform turns it into ready-made instructions. No need to be a prompt engineer.

## In what roles are agents used

Athena-based AI agents most often work in the following roles:

* **Sales agent** — lead qualification, product questions, converting to an inquiry
* **Support agent** — FAQ 24/7, escalation of complex requests to a manager
* **Admin agent** — booking services, reminders, collecting contacts
* **HR agent** — initial candidate screening, answers about the vacancy
* **Marketplace agent** — replying to buyers on [Avito](/documentation/documentation-en/channels/marketplaces/avito.md) and more.

Detailed examples by industry — on the page [**Use cases**](/documentation/documentation-en/use-cases.md).

## How payment works

Payment **based on the volume of AI messages** — you choose a plan with the required limit. All features (messengers, CRM, calendar, mailings) are included in every plan.

* **Free:** 100 messages / month — to get acquainted with the platform
* Discounts for payment for 3, 6, or 12 months

More details — on the page [**Pricing**](/documentation/documentation-en/prices/pricing.md).

### What is the average cost per month?

The cost depends on **number of conversations**, **volume of instructions** and **size of the knowledge base** — the more complex the scenario, the more context the model processes for each response.

Guidelines:

* **Simple cases** (FAQ, contact collection) — fit within basic plans
* **Complex cases** (multi-step sales, large knowledge base, integrations) — a plan with a larger message limit is needed

```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
