Let’s build something that talks. In the next 5 minutes, you’ll create a voice agent and have an actual conversation with it — right in your browser. No phone number needed, no credit card, no complicated setup. By the end, you’ll have a working agent you can customize however you want.

​
Create your agent

1

Sign in

Head to blackbox.dasha.ai and sign in. If you don’t have an account yet, creating one takes about 30 seconds.
2

Create a new agent

From your dashboard, click Create Agent. You’ll see a form with a few fields to fill in.
3

Set up the basics

Here’s what to enter:
FieldWhat to put

LanguagePick English (USA) for now
System PromptTry: You are a friendly assistant. Keep your answers short and conversational.
4

Save it

That took about 2 minutes. Nice work!

​
Talk to it

Now for the fun part — let’s hear your agent speak.
1

Start a test call

Click the Test button in the top right corner. Your browser will ask for microphone access — go ahead and allow it.
2

Say something

Try: “Hello, what can you help me with?”
3

Listen

Your agent will respond — using the same voice and AI that it’ll use in production. This isn’t a simulation; it’s the real thing.
You’re at about 4 minutes now. One more quick thing.

​

Every conversation gets recorded, so you can review what went well and what to improve.
