The AI assistant that greets your customers at life size
HoloChron is a photorealistic digital colleague: receptionist, customer service agent, event host, sales assistant or trainer. It understands the question, answers from your own knowledge base, books, guides and informs, in 74 languages, up to 24/7. We build, install and operate it.
Digital colleague, display and operation in one system
HoloChron is a Hungarian-built technology package: a photorealistic digital assistant appears at life size and holds a real conversation with your customers. Not a pre-recorded video and not a chatbot with a face: it understands speech, answers from your knowledge base and live systems, and keeps the conversation on task with a guided storyline.
Language model, speech recognition, natural voice and context-aware reactions, connected to your knowledge base and systems.
Box, MiniBox and Kiosk: hologram-effect, life-size or counter-top displays.
Delivery, installation, monitoring and support in monthly operating-hour packages, up to 24/7.
Speaks Hungarian and foreign languages naturally; handles live data, bookings, queue numbers and directions.
Four building blocks, combined as you need

From the quote request to the live assistant
A narrowly scoped assistant takes a few weeks; a complex, expert-level knowledge base several months. We give you the exact timeline after the needs assessment.
You describe the venue, the audience and the goal; we recommend a package and send a precise quote.
Data collection, profiling, training, 3D modelling, voice, integrations. Beta version, test interface, fine-tuning on your feedback.
We deliver, install and demonstrate the display on site. Box delivery is free for rentals longer than 30 days.
Monthly operating-hour package with continuous monitoring. The finished assistant can be reused at new venues without a new development fee.
Three items, a transparent fee structure
The assistant and the integrations are one-off development fees; the display and the operation are rental-type items. The exact quote is prepared once we know the venue, the period and the task, typically within one business day.

Read the articleWhat most people ask first
Is it really a hologram? What does the visitor see?
The Box is a specially lit 4K display with deep spatial effect: the character appears at life size, standing in space, which is why people perceive it as a hologram. No glasses or darkened room needed, only a covered space with controlled light.
How long does it take to build an assistant?
A narrowly scoped Basic assistant takes a few weeks. A Standard or Premium knowledge base spanning several topics takes about four months on average, because it needs research, expert review and several test rounds.
Can it be rented for a single day, for example for an event?
Yes. The Box, the MiniBox and the Kiosk can be rented for a single day with tiered daily rates. Delivery beyond 10 km from Budapest is charged by distance; Box installation is free for rentals longer than 30 days.
What internet and power do we need on site?
The Box needs a stable, preferably wired connection (500 Mbps recommended) or excellent 4G/5G, plus continuous 110–240 V mains power. The MiniBox and the Kiosk work with a good mobile connection as well.
