How the demo works

From website to a receptionist that knows your business, in one sitting.

No forms to fill out about your hours. No scripts to write. Otto does the homework.

01

Drop your site

Tell us your business name and website. That's the whole setup.

02

Agents go to work

Otto's agents crawl your pages, read your structured data and check what the web says about you.

03

Knowledge base, built

Services, prices, hours, policies and the questions your callers actually ask. Watch it assemble live.

04

Otto calls you

Pretend you're a customer and grill it. Like what you hear? Book a setup call right there on the phone.

What Otto does

The front desk that never takes a day off.

Every missed call is a customer calling the next business on the list. Otto picks up on the first ring, every time.

Answers every call

Nights, weekends, lunch rush. Callers get a real answer instead of voicemail.

Knows your business

Your services, prices, policies and hours, straight from the source, in your tone.

Books appointments

Connects to your calendar and books right on the call, no back-and-forth.

Captures every lead

Name, number and what they need, logged to your CRM or texted to you instantly.

Knows when to hand off

Urgent or complicated? Otto takes a clean message or transfers to your team.

Learns as you go

Anything not on your site, you teach it once in plain English. It never forgets.

The right builder + AI partner

Otto is what Outerstack builds in a week. Imagine what we'd build for you.

Outerstack designs, builds and runs custom software and AI agents for businesses that would rather grow than fiddle with tools. Otto is one of them: agents that research, a knowledge base that writes itself, a voice that answers your phone.

The demo you're about to see was built by a small team that ships. That's the point.

Questions

Good questions. Otto would answer them too.

Is this really AI on the phone?

Yes. Otto listens, understands and answers in real time using the knowledge base built from your site. Nothing is pre-recorded.

What do you do with my information?

We read your public website to build the demo, and use your contact details to reach you about Otto. We don't sell your data. You can ask us to delete your demo at any time.

Will Otto call me without asking?

No. Otto only calls the number you enter, once you tick the consent box, and only for this demo. You can also skip the call and talk to Otto in your browser.

What if Otto doesn't know an answer?

It won't make things up. It takes a message or offers a callback, and in a real setup you teach it the answer once and it remembers.

Do I need a new phone number?

No. Otto can answer overflow and after-hours calls on your existing number, or get its own line. We set it up with you.

Hear Otto answer for your business.

Sixty seconds from now it'll know your services better than your newest hire.
