HoloChron AI

The assistant that understands, thinks and answers

The heart of the system is a photorealistic digital person. It can be a receptionist, a guide, a tutor, a historical figure or your own digital twin. It works from a custom knowledge base, converses along a guided storyline and speaks with a natural voice in 74 languages.

What you get

Not a chatbot with a face: a digital person

Guided storyline

Directed conversation and storytelling: the character keeps attention focused and brings wandering questions back to the topic.

74 languages

Lifelike appearance and a natural voice in Hungarian and foreign languages. It answers in the visitor's language and can switch mid-conversation.

Custom knowledge base

The fee depends on the complexity of the knowledge base: from a single well-defined topic to an expert-reviewed simulation.

Pay once

You do not buy the finished character and knowledge system again when you use it at another venue or event later.

Packages

Three levels of complexity

We recommend a level based on the use case, but you choose freely. The final fee is determined by the scope of the knowledge base and is quoted after the needs assessment.

Reception, info point

Basic

  • Knowledge base for one well-defined topic
  • Natural conversation in 74 languages
  • Finished character with one appearance
  • A few weeks' lead time
Basic packageone-off development fee
Information, education, guiding

Standard

  • Everything in Basic
  • A more complex knowledge base spanning several topics
  • Custom appearance, several outfit variants
  • Later modifications and knowledge updates available
iFor complex topics the final fee can be a multiple of the base package: the scope of research and expert review determines it, and development can take several months.

Training, simulation

Premium

  • Everything in Standard
  • Complex, expert-depth knowledge base: training, simulation, tests
  • Several character appearances and outfits
  • Priority support, continuous development

Digital twin

An assistant modelled on a real person

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

Later

Knowledge updates

Nothing to buy now. New information, products, answers, documents and conversation flows can be added to the finished character later. The fee depends on the scope and complexity of the change.

Quoted on requestby the scope of the change
Add-ons

What else should the assistant know?

Object presentation, recommendations and connection to your systems. You pay once for the approved integration and content; later you reuse them at a new venue without a new development fee.

Object and product presentation, recommendations

The character talks about the product, answers questions and gives personalised recommendations. One topic is one coherent group of products or objects. The first topic is free with your first purchase.

The visual and 3D material needed (spot, product video, photo, 3D object, animation) is a separate, one-off content production item, quoted by quantity and complexity.

First topic freefurther topics quoted on request

System and API integration

  • Live information: opening hours, programmes, prices, stock, timetables, appointments
  • Booking and sales: appointments, tickets, quote requests, orders
  • Your own systems: CRM, ERP, product database, internal knowledge base
  • On-site processes: maps and routes, access control, queue numbers, event programme

One integration means the secure connection of one independent system; the final fee depends on the API documentation and the operations required.

How we work

Seven phases from needs assessment to project close

Depending on the package and the type of model, the full development of a character varies in duration; for complex knowledge bases it averages four months. We give the exact timeline once we know the specification.

First stepsneeds assessment, pricing, contract
Needs assessmentWe get to know your ideas in detail: audience, venue, goal, tone.
PricingWe select the most suitable package and send a precise quote.
ContractWe agree on the terms, milestones and deadlines.
Knowledgedata collection, profiling, training
Data collectionWe gather the information needed: documents, sources, product data, voice recordings.
Profiling and trainingWe shape the character's traits and systematically train the language models on the knowledge base.
Appearance3D modelling, beta version
3D modellingWe start building the character in space. For a real person, the first studio session happens in this phase.
Beta versionThe first beta is ready, about 45% complete in looks and basic interactions.
Communicationtest interface, feedback, second studio session
Communication platformWe provide a test interface where you and your team can talk to the character.
Testing and feedbackWe test the character and collect feedback.
Studio work, session 2For a real person: detailed voice recordings, video interviews and motion analysis for a lifelike result.
Refinementsuggestions, live demo, fine-tuning
Integrating suggestionsWe build in the findings of the test phase.
Live demoWe test the character live in the HoloChron Box so you can assess progress directly.
Fine-tuningWe finalise the character based on the consolidated feedback.
On siteinstallation, handover
InstallationWe deliver the display to the venue and put it into operation.
HandoverFull presentation of the character and the system, training for your on-site staff.
Closingoperation, project close
OperationWe ensure smooth operation, monitoring and support as agreed in the contract.
Project closeAt the end of the contract we dismantle and remove the display; the character remains yours for the next venue.
Good to know

What do we need from you?

The success of a project depends on fast, precise communication and knowledge sharing. Our developers collect every available piece of information, but for the most lifelike result we ask our clients to share everything relevant about the planned character's personality, knowledge and tasks.

For living people, in addition to the studio life-story interview and our questionnaire, further detailed information may be needed.
