nuseum
nuseum is an AI-powered digital audio guide for museums. Visitors open a web app in their phone browser, with no download, and explore exhibits through layered content, open questions and personalised tours in up to 20 languages.
What is nuseum?
nuseum is a digital audio guide for museums and cultural institutions, published by KOHATECH FlexCo, a Vienna company registered in the Austrian commercial register on 22 February 2025 and run by its two founders, Julian Harbort and Florian Kowarsch. Its registered business purpose is software for museums, cultural institutions and their visitors, which matches the product exactly.
The tool comes in two halves. Copilot is the visitor-facing web app. It opens in a smartphone browser with no download, is offered in up to 20 languages, and carries interactive AI content rather than a fixed recording. Information is arranged in layers, from an introduction through themes and sub-chapters to open questions, so visitors choose how deep they go. They can ask anything in text or by voice and get an answer in real time with the exhibit context already loaded, follow a guided tour built by the museum, or have the AI assemble a personalised route from their own interests.
Curator Space is the content management side, used by the museum's mediation team. It generates guide content from documents the institution already owns, such as exhibition texts, guided-tour scripts and reference literature, which become the AI's knowledge base. It translates automatically into the target languages, and it reports back on visitor feedback and on which themes are most consulted. The stated point is autonomy: no developer, no voice talent and no budget approval needed.
The commercial model is unusual and central to the pitch. Under the revenue-share option the museum sells guide access to visitors as a paid extra and nuseum takes a share of that revenue, so the institution carries no upfront cost. A monthly subscription is offered instead when the museum wants to give visitors free access. Neither the share nor the fee is published.
The vendor argues from a specific problem: it says 90% of native museum apps reach fewer than 3% of visitors, and claims 15% usage and a 4.5-star rating for its own guide. Named references are the Klimt Villa, the Secession and the Ernst Fuchs Museum, all in Vienna. Rollout is announced within a few weeks.
What it does
- Generate audio guide content from a museum's existing documents in minutes using AI
- Answer visitors' open-ended questions in real time, with the exhibit context already in hand
- Translate the whole guide automatically into up to 20 languages at no extra production effort
- Deliver the guide as a browser web app that visitors use without installing anything
- Build guided tours, or let AI assemble a personalised route from a visitor's preferences
- Layer information from a short introduction down to sub-chapters and open dialogue
- Collect visitor feedback and reveal which themes actually draw attention
When to use nuseum / When not to
A quick filter to help you decide if nuseum is the right fit.
When to use nuseum
- Small and mid-sized museums with limited budgets, which the revenue-share model lets equip themselves without any upfront spend
- Curators and mediation teams who want to produce and update guide content themselves, without developers or voice actors
- Institutions running temporary exhibitions, where a conventional audio guide is never worth its production cost
- Museums welcoming international audiences, thanks to automatic translation into up to 20 languages
- Cultural venues looking to turn visitor mediation into an additional source of ticket revenue rather than a cost centre
When not to use nuseum
- Teams that need a native iOS or Android app: nuseum is deliberately a browser-based web app only
- Developers looking for an API or integrations, as no public API, documentation or third-party connector exists
- Buyers who need a published price list, since no amount whatsoever appears on the site and every path leads to a sales conversation
- Organisations with strict procurement rules, as no terms and conditions and no data processing agreement are published
- Anyone outside the cultural sector: the product, its content model and its vocabulary are built specifically around museums and exhibitions
How to use nuseum
A typical end-to-end flow, from setup to results.
- Reach out through the contact page, by email or by phone, as there is no self-service sign-up
- Discuss which of the two billing models fits: revenue share on guide tickets, or a monthly subscription
- Gather the institution's existing material, such as exhibition texts, guided-tour scripts and reference literature
- Load that material into Curator Space, where it becomes the knowledge base the AI draws on
- Let the AI draft the guide content from those documents, then review and adjust it as a mediation team
- Structure the content in layers, from introduction through themes and sub-chapters to open questions
- Assemble guided tours through the exhibition, and enable AI-generated personalised routes
- Trigger automatic translation into the languages the institution wants to serve
- Publish the guide, which visitors then open in their phone browser without any installation
- Review visitor feedback and the most consulted themes in Curator Space, and refine the content accordingly
Pros & Cons
Pros
- No upfront investment under the revenue-share model, which removes the usual budget barrier for small institutions
- Nothing to install for visitors, which sidesteps the download step that kills most native museum apps
- Up to 20 languages without extra production work, where a conventional guide would need a recording per language
- Mediation teams stay autonomous, with no dependency on developers, voice talent or budget approvals
- Rollout announced within a few weeks, working from documents the museum already has
- European vendor, with an Austrian controller, named subprocessors and a detailed GDPR privacy notice
- Named, verifiable reference institutions rather than anonymous testimonials
Cons
- No price is published at all: neither the revenue share percentage nor the monthly subscription amount
- No terms and conditions are published in any of the site's three languages
- No data processing agreement is offered, although the vendor explicitly describes itself as the museum's processor
- The 20 supported languages are never listed, so coverage cannot be checked before a sales conversation
- No API, no integrations and no native mobile app
- No security certification is claimed and no hosting region is disclosed, only that AWS runs the infrastructure
- A very young and very small vendor, registered in February 2025 and run by two people
Pricing & Plans
No price is published on the site. nuseum presents two billing models without attaching an amount to either. Under the revenue-share model the museum sells guide access to its visitors as a paid supplement and the vendor is remunerated solely from a share of that revenue, so the institution states no cost of its own. Under the subscription model, chosen when the museum prefers to offer the guide free of charge to visitors, a monthly fee applies. Neither the revenue-share percentage nor the monthly fee is disclosed, and there is no free plan, no free trial and no self-service sign-up. Pricing can only be obtained by contacting the vendor.

Data, GDPR & hosting
A consolidated view of how nuseum handles your data.
GDPR overview
GDPR implementation is concrete and documented. The privacy policy is written under Articles 13 and 14 GDPR together with the Austrian Telecommunications Act, names KOHATECH FlexCo as controller under Article 4(7), and states a legal basis for each purpose under Article 6, including consent for Google Analytics. Data subject rights are listed explicitly: access, rectification, erasure, objection, portability and withdrawal of consent. The competent supervisory authority is named with its address. Non-EU transfers are addressed through the EU-US Data Privacy Framework and the Israeli adequacy decision. No Article 27 representative is designated, which is consistent with a controller established in Austria. Two gaps remain: the site never claims compliance in so many words, and no data processing agreement is published even though the vendor describes itself as a processor for museums.
Who owns the data?
The privacy policy names KOHATECH FlexCo, in Vienna, as the controller under Article 4(7) GDPR for the website. It then states an important reversal: when a museum or cultural institution uses the nuseum application, the institution is the controller and KOHATECH FlexCo acts as its processor. The museum therefore keeps the driving seat over visitor data and over the exhibition content it supplies, which the policy describes as texts, guided-tour scripts and literature. No terms and conditions are published anywhere on the site, in any of its three languages, so no contractual clause on content ownership, licensing or reuse could be examined. That contractual layer has to be requested directly from the vendor.
Reuse rights
No terms and conditions are published on the site, so nothing states whether an end user may reuse data without permission. Only the privacy policy speaks to use, and it stays within a processing logic rather than a licensing one. For the website, nuseum processes browser and device data, IP address, pages visited, appointment-booking details and contact information, on the basis of legitimate interest, contract or consent. For the application, it processes device data, timestamps and the content of prompts typed or spoken by visitors, and explicitly advises that no personal data should be entered into the application at all. Content used to build a guide comes from the museum itself, and the museum remains the controller of it. The policy also confirms that no automated decision-making or profiling takes place, and that no advertising cookies are used.
Data retention & training
Hosting summary
nuseum publishes no hosting country or region. Its privacy policy lists recipients and their corporate business locations, which is not the same statement. Amazon.com, Inc. is named for hosting the software infrastructure behind Copilot and Curator Space, with a business location given as the USA and coverage under the EU-US Data Privacy Framework, but no AWS region is disclosed. Wix.com Limited is named for hosting the marketing website, with a business location in Israel covered by the European Commission's adequacy decision, so the website and the platform do not share an infrastructure. Google LLC and HubSpot, Inc. appear as further recipients for workspace, analytics and CRM, both listed under the EU-US Data Privacy Framework. The controller itself is established in Vienna, Austria, and the Austrian supervisory authority is named. Anyone with a data residency requirement should ask directly which AWS region holds visitor and content data, since the site does not answer that question.
Things to keep in mind
Risks and trade-offs to weigh before adopting nuseum.
- No pricing is published anywhere, so the real cost of ownership only becomes visible inside a sales conversation
- No terms and conditions exist in any language of the site, leaving content ownership, liability and termination undefined
- No data processing agreement is offered although the vendor describes itself as the museum's processor, which a public institution will need contractually
- The privacy policy dates from 1 March 2025 and still describes Wix website hosting and Wix cookies, while the site is now served as static pages behind a different infrastructure: the document has not been kept current
- An AI answering visitors' open questions about artworks can state things confidently and wrongly, so curatorial review of the knowledge base and of the tone matters more than the setup effort suggests
- Usage figures are the vendor's own and unaudited, including the 15% usage rate, the 4.5-star rating and the 90%/3% claim about native museum apps
- Brand confusion to avoid: nuseum.io is an unrelated company operating a nutrition AI platform, with no connection to this museum audio guide
Setup & Integrations
Technical difficulty
Very low on the technical side. Visitors install nothing and simply open the guide in their phone browser. For the museum there is no API, no connector and nothing to configure, and the vendor stresses independence from technology, voice talent and budget approvals. Rollout is announced within a few weeks from documents the institution already holds. The real effort is editorial rather than technical: assembling exhibition texts, tour scripts and literature, then reviewing what the AI drafts from them so the tone and the facts match curatorial standards.

Should you pick nuseum?
nuseum addresses a real and well-identified problem. Conventional digital guides are expensive to produce, hard to keep current, and largely unused, and the vendor quantifies that failure rather than gesturing at it. Its answer is coherent on both sides: a browser web app that removes the download step for visitors, and a CMS that lets a mediation team build and translate content from documents it already owns, without developers or voice talent. The revenue-share model is the most striking part, since it converts what is normally a capital expense into a share of ticket revenue and makes the tool reachable for small institutions. Named Viennese references and a blog still active in January 2026 suggest a product genuinely in service rather than a pitch.
The reservations are mostly about what is not published. No price appears anywhere, so no institution can budget without a sales conversation. No terms and conditions exist in any of the site's three languages, and no data processing agreement is offered even though the vendor explicitly casts itself as the museum's processor: for a public body with procurement rules, that gap has to be closed contractually before anything else. The 20 languages are never listed, no hosting region is disclosed, and no security certification is claimed. The company itself was registered in February 2025 and is run by two people, which is normal at this stage but worth weighing for a multi-year commitment.
For a museum that wants modern, multilingual mediation without capital outlay, nuseum deserves the conversation. Go into it with a list: the exact revenue share, the language list, the hosting region, and a signed processing agreement.
