Create a Voice Agent The Voice Agent Builder supports two editing approaches: a visual node editor for designing stages and pathways, and a raw text editor for writing the conversation flow directly. You can create a new agent from the dashboard. Describe your use case and Tig.ai generates a starting workflow with default prompts and pathways, which you can then edit.

​
The graph model

A workflow is a directed graph:
  • Nodes represent a stage of the conversation or an action (e.g. greet the caller, collect an address, transfer the call).
  • Pathways (edges) connect nodes and represent the routes the LLM can take depending on what the caller says. The LLM decides at runtime which pathway to follow.
A workflow should have only one Start Call node and typically ends at an End Call node, with Agent nodes and other node types in between. See Editing a Workflow for how nodes, pathways, and node-level toggles fit together.

​
Node types

Beyond nodes, you can extend an agent with:
  • Tools — let the LLM call external APIs or transfer calls mid-conversation.
  • Knowledge Base — attach documents the agent can reference during a call.
  • Pre-Call Data Fetch — enrich context with an HTTP call before the agent starts speaking.
  • Template Variables — reference initial_context and gathered_context values in prompts and payloads.

Where to start

  1. New to Tig.ai? Follow Editing a Workflow to learn the fundamentals of nodes and pathways.
  2. Want to test immediately? Use a Web Call from the agent editor — no telephony setup required.
  3. Ready to go live? Configure a telephony provider and set up inbound routing.
  4. Need the call to hit your systems? Add a Webhook node to sync results to your CRM or automation tool.
  5. Want to embed the agent on a website? See Add to Website.
