Frequently asked questions

Not in the strict physical sense. HoloChron displays are not free-floating laser holograms; they are screen-based displays in which the character appears life-size, standing in space, which is why viewers experience it as a hologram. No glasses or darkened room are needed. On this site we use the terms “hologram-effect” and “spatial-effect” in that sense, to describe the visual experience.

A complex AI-driven character modelling system that integrates several technologies from voice cloning, speech recognition and language models to 3D character modelling. The result is a digital person who understands the question, answers from its own knowledge base and keeps the conversation on task with a guided storyline: receptionist, customer service agent, host, sales assistant, tutor or historical figure.

The assistant does not pick from pre-recorded videos and does not only write text: it understands speech in real time, answers from its knowledge base and live systems, with a natural voice and facial expressions, at life size. Thanks to the storyline it does not wander off; it brings the conversation back to the task and signals when a human colleague is needed.

Hungarian and the major foreign languages, naturally and without delay. The assistant answers in the visitor's language and can switch languages mid-conversation. The knowledge base is built once; languages do not multiply the development fee.

A narrowly scoped Basic assistant takes a few weeks. A Standard or Premium knowledge base spanning several topics averages four months, because it needs research, expert review, several test rounds and a live demo. We give the exact timeline once we know the specification.

All relevant information about the planned assistant's knowledge, tasks and tone: documents, frequently asked questions, product data, policies, access to the documentation of the systems to be integrated. For a digital twin of a real person, a studio interview and a questionnaire are part of the process.

Yes. New information, products, answers, documents and conversation flows can be added; the fee depends on the scope and complexity of the change. Updates do not have to be purchased in advance.

Yes: your own or a colleague's digital twin in appearance, voice and style. We work from existing footage or a studio recording, and quote the fee once we know the material. EU AI Act compliant: with written consent and transparent AI labelling.

HoloChron AI captures the essence of a historical personality from sources and reinterprets it digitally. Visitors can explore the great figures of the past interactively; they answer in a period voice and style, supporting education, heritage preservation or entertainment.

The Box is not just a display: it is a life-size, interactive spatial-effect surface that shows digital characters or live-streamed people lifelike, with a sense of depth. A 218 cm 4K screen, 20-point touch, a built-in 12 MP camera and speakers in a 208 × 123 × 60 cm unit weighing over 300 kg.

It is a specially lit display with a deep spatial effect: the character appears 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; we avoid direct sunlight and strong backlighting.

The Box is for a life-size assistant with the strongest hologram effect: lobbies, receptions, events, museums. The MiniBox (70 × 55 × 45 cm) is for counters, cabinets and shop windows and product presentation; it fits in a car. The Kiosk (192 × 64 × 50 cm) is a standing LED panel for a full-body character where space is tight. Details on the displays page.

The Box needs min. 500 Mbps download and upload or excellent 4G/5G coverage for delay-free conversation; a wired connection is recommended. The MiniBox and the Kiosk work with a stable wired or good mobile connection. At events we test the network in advance.

AC 110–240 V, 50/60 Hz reliable supply and uninterrupted power. For generator-powered venues we agree this in advance.

A closed, covered, dry space; a level floor bearing over 300 kg; a door, lift or corridor suitable for the 208 × 123 × 60 cm unit. You can attach a site photo to your request so we can check the route in advance.

No. We provide all the software and hardware needed, including the display and the AI platform. On site you only need power and stable internet; we handle installation and monitoring.

Yes, the assistant can also be deployed on your own display or a web interface; the hologram effect is strongest in the Box. We confirm compatibility once we know the existing equipment.

The displays need a closed, covered, dry space. At outdoor events a covered stand, tent or pavilion with controlled light can be a solution; we agree this in advance.

It consists of three items: the assistant's one-off development fee (Basic, Standard or Premium package by the depth of the knowledge base); the display's daily rental, which is tiered and cheaper for longer periods; and the monthly operating package. We quote exact prices in a tailored offer once we know the venue and the task. After sending the quote request form you also receive a link to the online configurator (Hungarian interface), where you can build your package item by item.

Yes. The Box, the MiniBox and the Kiosk can be rented for a single day with tiered daily rates. For short rentals the operation is charged pro rata, in proportion to the daily operating hours, with a short-term surcharge.

Box delivery and installation is a one-off item, waived for rentals longer than 30 days and for annual contracts. Beyond 10 km from Budapest we charge a distance-based travel fee; MiniBox and Kiosk delivery is cheaper. We specify the fees in the quote.

Operating hours are the system's active time per month. Start: 120 hours (about 4 a day), Basic: 240 (8 a day), Standard: 360 (12 a day), Premium: 720 (24/7). The package includes continuous monitoring, support and the cloud resources. We recommend a package based on the daily hours.

No. You pay once for the approved assistant, knowledge base, integration and content; later you use them at a new venue or event without a new development fee. Only the display rental, the operation and any delivery recur.

With an annual contract the lowest daily-rate tier applies and we waive the delivery and installation fee. It is the most favourable arrangement for a permanent reception, info point or museum.

The object and product presentation function (first topic free alongside an assistant) extends the character's knowledge. The spot, product video, photo, 3D object or animation actually shown on the display is a separate, one-off content production item, quoted by source material and quantity.

After the quote is accepted we sign a contract with milestones: the development fee in instalments, the rental and operation monthly or tied to the event. The details are set out in the quote.

Conversations are processed to the extent and for the time necessary for the service; the assistant does not collect personal data unless the task requires it (for example a booking). We design integrations according to your data-protection rules. Details in the privacy notice (Hungarian).

The assistant always discloses that it is an AI; for digital twins of real people we work with written consent and transparent AI labelling. You approve the content of the knowledge base; the character does not improvise outside the approved framework.

The operating package includes continuous monitoring: on a network problem the assistant tells the visitor it is temporarily unavailable and we intervene remotely. At events we provide a backup route and an on-site operator.

Yes. In the videos our own characters answer random questions, and in our Budapest studio you can test the Box and a working assistant live, with your own questions. Book an appointment.
