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

Click Save Agent — and that’s it! Your agent exists now.
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.

​
See what happened

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

Click Calls in the left sidebar.

Find your test call

It’ll be at the top — the most recent one.
