How long does it take to build a Voice & Chat bot?

About 5 minutes. Enter a website URL, scan it, customize the greeting, and deploy.

Can the bot answer questions it wasn't trained on?

No — the bot only answers from its knowledge base. When it doesn't know something, it says so and offers to connect the visitor with a human.

Do visitors need to install anything to use voice?

No. Voice works directly in the browser. Click the microphone button and start talking.

Can I give a bot its own phone number?

Yes. Enter a local area code, click Assign, and the bot gets a real phone number customers can call.

Can the bot book appointments?

Yes, on Starter plans and above. Connect Cal.com — the bot handles booking automatically via chat, voice, or phone.

Everything you need to build, customize, and deploy AI Voice & Chat bots with OurBotBuilder.

Getting started in 5 minutes

Create Bot

Scan Website

Paste any business URL — we crawl and train the bot on that content.

Choose Voice

Pick from 10 voice characters — see them all in the bot editor.

Test Demo

Talk to the bot in the demo tab. Type or click the microphone.

Deploy

Copy one line of code and paste it into your website's HTML.

Voice characters

OurBotBuilder ships with 10 OpenAI voice characters, each with a distinct timbre:

Alloy — neutral, balanced, approachable
Echo — calm, smooth, trustworthy
Shimmer — soft, warm, reassuring
Ash — casual, conversational, friendly
Ballad — expressive, narrative, engaging
Coral — warm, welcoming, customer-service-ready
Sage — calm, professional, knowledgeable
Verse — expressive, energetic, dynamic
Marin — clear, professional, articulate
Cedar — deep, authoritative, confident

Legacy Gemini voice names (Puck, Charon, Kore, etc.) are still supported for existing bots and auto-map to their OpenAI equivalents.

Dedicated phone numbers

Assigning a phone number

Any bot on the Starter plan or above can get its own real phone number. In the bot editor, scroll to Phone Number, enter a local area code (US or Canadian), and click Assign. Costs ~$1.15/month per number, billed via Twilio.

What the phone number does

Customers call the number and talk to your AI directly. The bot uses the same knowledge base, same voice, and same personality as the web widget. It answers 24/7, captures leads, and can book appointments.

SMS lead alerts

When the bot captures a lead's contact info in a conversation, instant SMS alerts fire to:

The business owner (so they know a lead came in)
The agency reseller (if applicable — hidden by default in white-label mode)
The lead themselves (a thank-you text)

Configure alert phone numbers in the bot editor's SMS Alerts tab.

Calendar booking

Setting up calendar

Connect a Cal.com account in the bot editor. Set your availability in Cal.com — the bot reads it live during conversations and books appointments automatically. Works in chat, voice, and phone.

How booking works

The bot detects booking intent, checks live availability, presents time slots to the customer, confirms, and creates the event in your calendar. All hands-free.

Website embedding

Copy the embed code from the bot editor's "Install on Website" tab and paste it before the </head> tag in your site's HTML. Works on any platform:

WordPress: use the "Insert Headers and Footers" plugin, or edit header.php
Shopify: add to theme.liquid before </head>
Squarespace: Settings → Advanced → Code Injection
Wix: Settings → Custom Code → Add Custom Code
Google Tag Manager: create a Custom HTML tag
Static HTML: paste before </head>

Frequently asked questions

How long does it take to build a Voice & Chat bot?: About 5 minutes. Enter a website URL, scan it, customize the greeting, and deploy. Large sites may take a few minutes longer to scan.
Can the bot answer questions it wasn't trained on?: No — the bot only answers from its knowledge base. When it doesn't know something, it says so and offers to connect the visitor with a human. This prevents hallucination and ensures accuracy.
Do visitors need to install anything to use voice?: No. Voice works directly in the browser. Visitors click the microphone button and start talking. No app, no download, no plugin.
Can I give a bot its own phone number?: Yes. In the bot editor, enter a local area code and click Assign. The bot gets a real phone number that customers can call. The AI answers just like it does on the website — same voice, same knowledge.
Can the bot book appointments?: Yes, on Starter plans and above. Connect Cal.com, manage availability there, and the bot handles booking automatically via chat, voice, or phone.
How do SMS notifications work?: When a lead is captured, SMS alerts go to your client and to you. The lead also gets a thank-you text. If the bot has its own phone number, texts come from that number.
Can my clients see OurBotBuilder branding?: Only if you leave it on. On paid plans, use the Brand Studio to hide "Powered by" and replace it with your own brand.
Does the bot work on mobile?: Yes. The chat widget is fully responsive on phones, tablets, and desktops.
Is there an API?: Yes, on the Enterprise plan. Get your API key from Settings and programmatically access bot logs and status.
What if my customer doesn't want to install a chat widget but has missed calls?: Use the Missed-Call Text-Back product ($29/month) — no widget, no changes to their phone number. Unanswered calls forward to a text-back number, and callers get an auto-text within seconds.
