AI voice that sticks to the script.

With every line written and approved before it's spoken, Visibyl is voice interaction you can actually rely on.

A natural conversation

With no lag or awkward pause, responses come the instant someone stops speaking. And because every response is pre-recorded, real voice actors can bring every line to life.

That runs offline

Everything runs on your own hardware, so it keeps working even when the Wi-Fi doesn't. Nothing leaves the building, and there's no cloud bill that climbs with every conversation.

And drives the show

With the ability to trigger lights, effects or the next story beat, the conversation becomes an experience. Each response, a moment to remember.

For when every word counts.

Built for brands, licensed characters, cultural content and any experience where a wrong word carries real consequences. Nothing is generated live, so responses aren't improvised and can never drift off-brand. Safe for licensed IP, and anywhere accuracy and tone aren't optional.

Learn what your audience wants.

Every question is captured anonymously, building a clear picture of what visitors are curious about, which topics come up most, and where your content has gaps. Those insights feed back into the experience, improving it over time, without collecting any personal data.

Case study, The Met Collection:

When the Metropolitan Museum of Art released over a hundred 3D-scanned works into the public domain, we built a conversational experience around them. Visitors ask about the artifacts in their own words, and the objects respond, shifting from one to the next as the conversation flows.

Every answer is drawn only from the collection's own information. Ask something outside it and the system says so, and offers what it can talk about instead. Nothing is invented, and nothing is generated live.
