Inside Xebit's Zero-API Architecture

Most "AI demo" tools ask you to rebuild your product inside their SDK — re-create your screens, wire up their API, and keep both in sync forever. Xebit takes the opposite approach: it drives the real thing.

No SDK. No rebuild. Your live UI.

Xebit controls an actual headless browser instance and navigates your product the way a person would — clicking, typing, and scrolling through your live software. There's no integration to build into your product, no SDK to install, and nothing to keep in sync. "Open your pricing page" routes through the browser, not an API call. That's what we mean by zero-API: no API access into your product is required to demo it.

Three parts: a brain, a voice, and a pair of hands

Under the hood, the agent is split into three specialized layers, each doing one job well:

• The brain listens to the meeting and decides what to do next — which step to run, which question to answer, when to stay silent on a multi-party call.
• The voice is a real-time speech-to-speech model that understands interruptions and replies in under a second, in 20+ languages — so the conversation feels live, not scripted.
• The hands drive the browser through your product deterministically, executing the exact navigation the brain decided on.

Why deterministic control matters

The hard part of an AI driving real software isn't talking — it's not going off the rails. Letting a language model freely click around your UI is how demos break live. So Xebit separates the decision from the execution: the model decides intent, and a deterministic control layer carries it out reliably, the same way every time. You get the adaptability of an AI with the predictability of a scripted demo.

The model decides what to do. A deterministic engine makes sure it actually happens — every demo, the same way.

It runs where your buyers already are

Because the whole thing is browser-native, it runs anywhere a browser does: instantly in the page on your website, or inside a real meeting when the agent joins your Zoom, Meet, or Teams call. The moment the demo ends, the same architecture extracts the pipeline signals and syncs them to your CRM.
