# Agent Overview

An agent is an AI that can engage in a conversation and/or do work. Spara enables you to leverage multiple multi-channel agents that work together to engage your buyers and push them through your funnel.

Spara's agent types are:

* [Chat Agents](/agents/chat-agents.md) — website chat widgets (Navigator, Smartbar, Fullscreen)
* [Email Agents](/agents/email-agents.md) — automated email replies and outreach
* [Voice Agents](/agents/voice-agents.md) — inbound and outbound AI phone calls
* [Text Agents](/agents/text-agents.md) — SMS conversations

## Agent capabilities

Every agent is configured through the Agent Editor — a split-screen interface with the prompt on the left and the testing/AI panel on the right. The capabilities available to each agent type are summarized below.

| Capability                                                   | Chat | Email | Voice | Text |

## Shared behaviors

All agents share the following:

* **Knowledge** — Agents draw on your [Knowledge](/platform/knowledge.md) base (scraped webpages, uploaded documents, key questions) to answer factual questions. You control what's included and how frequently it's refreshed.
* **Analytics** — Every agent automatically tracks its conversion metrics in [Analytics](/platform/analytics.md). No setup required.
* **Drafts and publishing** — Edits create a draft. Leads interact only with the published version. Test drafts before publishing via the [Testing](/agents/agent-overview/testing.md) interface.
* **Starting criteria** — Each agent has conditions that determine when it activates. A chat agent might activate only on specific pages; a voice agent is attached to a phone number.
