This is the fastest path to a working voice agent. You’ll create an agent, get a generated conversation flow, and talk to it in your browser — no phone number, no telephony provider, no configuration.
Using the hosted platform, go to app.dograh.com. Self-hosting locally? Use http://localhost:3010 instead, and follow Getting Started first to get the platform running.

​
Step 1: Create an agent

Go to app.dograh.com/workflow and create a new agent. Create a Voice Agent You’ll be asked for:
  • Direction — Inbound (agent receives calls) or Outbound (agent makes calls). Pick either; it only affects the starting prompt.
  • Use case — a description of what the agent should do, e.g. “Book a haircut appointment, ask for preferred date and time, confirm before ending the call.”
This description is sent to an LLM to generate a starting workflow. The more specific you are, the better the generated prompts and pathways will be.

​
Step 2: Land in the workflow editor

After generation, you’re dropped into the Voice Agent Builder with a graph already built for you — typically a Start Call node, one or more Agent nodes with prompts for your use case, and an End Call node, connected by pathways. You don’t need to understand the full graph model yet — the generated agent works out of the box. You can come back and customize prompts once you’ve heard it talk.

​
Step 3: Talk to it with a Web Call

In the agent editor, start a Web Call. This runs the full pipeline — speech-to-text, LLM, text-to-speech — straight from your browser microphone, exactly like a real phone call would, just without a phone number. While the call is active, you can watch:
  • The live transcript as the conversation happens
  • Node transitions as the agent moves through the graph
  • Any tool calls the agent makes
Talk to it like a real caller would. Try to get it off-script — say something unexpected — and see how it responds.

​
Step 4: Iterate

Didn’t go the way you wanted? Open the node whose behavior you want to change and edit its prompt directly. Save, then start a new Web Call to hear the change immediately. No redeploy, no restart. Common first tweaks:
  • Adjust tone or wording in an Agent node’s prompt
  • Add shared instructions (tone, objection handling) to the Global node
  • Add a Webhook node to send call results somewhere once you’re happy with the flow

​
Next Steps

You have a working agent that runs entirely in the browser. From here:
  • Take real calls — connect a telephony provider and trigger calls via API Trigger or inbound routing.
  • Learn the graph model in depth — see Voice Agent Builder for all node types and how pathways work.
  • Give it tools — let the agent call external APIs or transfer calls with Tools.
  • Embed it on a website — skip telephony entirely and let website visitors talk to the agent via Add to Website.
