Agent Types

Three Ways to Build a Voice Agent

Some calls need open conversation. Some need the same few steps every time. Some need both. Edesy gives you three agent types for those cases, and several ways to start one without a blank page.

The three Edesy agent types

Edesy offers three agent types. A prompt-based agent follows one system prompt and its tools in free conversation. A flow-based agent follows a node flow with keyword and phrase matching and uses the LLM only as a fallback. An AI Flow agent is a visual graph where each node has its own prompt and tools.

How to Choose

Three questions that settle it

  1. Step 1 of 5: 1. Can the caller say almost anything?

    Pick a prompt-based agent. A support line or a sales call where people ask open questions works best with one well-written prompt and the right tools.

  2. Step 2 of 5: 2. Is the call the same few steps every time?

    Pick a flow-based agent. Confirming a delivery or reading a balance works well with rules, with the LLM as a fallback for anything unexpected.

  3. Step 3 of 5: 3. Does the call need structure and open conversation?

    Pick AI Flow. Lead qualification or appointment booking can move through fixed stages while each stage still handles natural replies.

  4. Step 4 of 5: 4. Start from something that works

    Use a template, copy an existing agent, describe the agent and let Generate agent draft it, or ask Copilot.

  5. Step 5 of 5: 5. Switch later if you need to

    The agent type can be changed from the agent editor, behind a confirmation step, so you are not locked in by your first choice.

When Each Type Fits

Match the engine to the call

Prompt-Based (AI-Powered)

One system prompt with {{variables}}, a knowledge base and tools. The model leads the conversation. The most flexible type, and it works with native audio models.

Flow-Based

A node flow that matches keywords and phrases and moves step by step, calling the LLM only when no rule matches. Predictable for simple, repeatable calls.

AI Flow

A visual graph on a canvas. Each node has its own prompt and tools, and a tool call moves the call to the next node. Structure without scripted replies.

Template Gallery

Order status, appointment scheduler, reminders, surveys, sales, real estate, solar, OPD assistant, EMI collection and more, many in Indian languages and bilingual versions.

Copy an Agent

Duplicate an agent that already works and change what differs, such as the language, the offer or the tools.

Generate Agent and Copilot

Describe the agent and let AI draft it, or build it by chatting with Copilot and approve the preview.
