About us
What is FD Finder?
FD Finder is a shared platform for working together against grapevine flavescence dorée (FD). Legislation is necessary, but on its own it cannot stop the disease: only the whole sector together can curb it – from growers to the authorities, at every level. For that, we provide shared knowledge and tools:
- FD Finder Expert knowledge base – the FD literature in one place; the Basic package is free with registration.
- Good practices – what was done against FD elsewhere in Europe, what worked and what did not.
- Phytoplasma Risk Index (FKI) – a monthly expert estimate of where the fight stands, with a European country map.
- Community pre-screening – in season, you photograph a suspicious vine, and the other members of the community indicate whether it is worth a closer look.
- FDsimulator – a teaching simulator on how the phytoplasma spreads and why control is a shared cause.
- Wine against FD – wineries’ wine donations for the work against FD.
The more of us share what we know and what we see, the sooner it becomes clear where the disease is spreading and what works against it.
The result is community pre-screening, not a laboratory diagnosis. A review does not determine whether a disease is present, and it does not replace expert assessment or laboratory testing.
We use the vine’s location to track the spread of the disease and for research. Reviewers and other users never see it, and we do not publish it either.
FD Finder is also a research project: the submitted photos and data also serve research into flavescence dorée and other grapevine diseases, as well as the development of AI systems that help recognise them – the Terms and the Privacy Notice set out the details.
Important: a submission to FD Finder is not an official plant-health notification. If you have a notification obligation under the law, you must fulfil it separately with the competent authority.
The project is currently in a development and testing phase: the interface, the way it works and the policies may change.
Initiator
I am Péter Mokos. I started out as an economist, but family tradition eventually led me to vines and wine.
In the Villány wine region, together with my siblings, my wife, our family and our committed colleagues, we run a family winery and a hotel. For us, vines and wine are not simply work: our family makes its living from them, our past is bound up with them, and the next generation sees its future in them too.
More recently, I have also entered the world of startup development. I learned a great deal from Péter Balogh – investor on Cápák között (a Hungarian television investment show) – and from the STRT team while working together.
That environment taught me that the best answer to a big problem is not necessarily a complicated system. Sometimes a simple tool, a good idea and the cooperation of many people can set real change in motion.
When flavescence dorée became an ever more serious threat to vines, for me it was no longer a distant plant-health problem. It was about our family’s future, our colleagues’ livelihoods and the values of an entire wine region.
That is why I started FD Finder.
I believe that if many vine growers share what they see in good time, we can notice trouble sooner – and together we have a better chance of curbing its spread.
Building the knowledge base taught me that legislation is necessary, but on its own it cannot stop the spread. Where Europe managed to slow it, growers, grower associations, the authorities, vine nurseries and researchers worked together. Today this is my goal: for FD Finder to support that cooperation – at every level.
The team
The FD Finder team consists of AI-supported team members. They are not real people and not employees: they are AI-based team members working in defined roles, whose work the initiator directs and checks.
Gepitechnical co-founder, architecture and deep review
Owner of the system’s structure and of the strategic technical decisions. Reviews a completed development round less often, but in depth: architecture, data model, security and data-protection questions. Supports the initiator in the big decisions.
Klaudiaautonomous developer
Sees long, continuous development rounds through from start to finish: designs, writes, tests and releases the features, then improves them based on the feedback. She writes the vast majority of FD Finder’s working code.
FD Finder Expertprofessional background in plant protection and viticulture
Owner of the professional content: the professional logic behind the symptomatological considerations, the survey protocol and the reviewer tutorial. This work is what connects the reality in the field with what the app asks.
FD Finder Expert’s knowledge base was built by processing more than 12,000 source documents: more than 82,000 pages of professional material, including more than 2,800 scientific papers (more than 1,300 of them in full text); documents of the official programmes and legislation against flavescence dorée in 28 countries and the EU; and transcripts of some 200 hours of professional video.
For the estimate of the Phytoplasma Risk Index (FKI), the three scoring expert models work with FD Finder Expert’s knowledge base, and FD Finder Expert prepares the written assessment for each sub-indicator. Publication is approved by the initiator. The FKI and its evaluation

Yogilegal officer
Our legal officer. His task is to make sure the app can operate in line with every data-processing and other legal requirement: he keeps watch that the policies and the way the system actually works stay consistent with each other, and he prepares the legal questions. The official legal opinion does not come from our legal officer – it is prepared by a practising lawyer.
Oktopuszproject manager and customer-service all-rounder
Our project manager and customer-service all-rounder. Has insight into the development processes, and keeps on top of our partners’ and users’ questions and cases. Like an intelligent, eight-armed octopus.
Manuellaresearch assistant
Supports the background work on the literature and research: organises the research materials, helps prepare the research plans and the data collection, and processes the professional sources. She is not an independent scientific decision-maker and not an accredited researcher – the collected material is always evaluated by a human.
Fannicommunity communications and press relations
Works on communicating the project in plain language: social media, the preparation of press materials and communication campaigns, and support for press relations.
How do we work?
The goals and the important product decisions are set by the initiator. The AI team members then work in their own roles: Klaudia sees long, connected development rounds through from start to finish, Gepi reviews the finished work less often but in depth, and the research and communications team members help in their own specialist fields.
Critical decisions and the release of every new version remain under human control: what users ultimately see is released by the initiator.
This way of working is what allowed a tool of this scale to come into being from a single professional initiative. But it has a limit, and we say so plainly: here, artificial intelligence does not replace the authority, the plant-health specialist, the research institute or the lawyer. FD Finder pre-screens and collects data – the professional decision remains a human one.
