Ukraine has launched Diia.AI on the Diia portal — the world’s first national AI agent that not only answers questions but also delivers government services directly in chat. For example, a user may request an income certificate and receive it instantly in their account with email notification. The initiative simplifies access, removes the need for forms or visits, ensures 24/7 availability, and aims to place Ukraine among leaders in public-sector AI.

Initiative overview

Diia.AI is a personal AI assistant that both advises users and delivers public services. Visually, it resembles familiar AI chatbots such as ChatGPT. In its initial phase, the assistant is available on the Diia web portal, with mobile app integration to follow.

  • As of today, Diia.AI can perform a range of tasks:
    Consultation & Navigation: it provides step-by-step guidance on accessing any service available on the Diia portal, as well as information about projects of the Ministry of Digital Transformation of Ukraine. For example, users may ask how to sell a car through Diia, submit an application under the eRestoration programme, or apply for a business grant via Diia.Business.
  • Service Matching Based on Life Situations: if a home has been damaged as a result of military actions, Diia.AI suggests the relevant service — eRestoration — and guides the user on how to upload photos and submit an application to the commission.
  • Service Delivery Without Extra Steps: the assistant enables services to be completed directly within the chat, making the process as simple and user-friendly as possible. The first available service is the income certificate. In future, more services will be added, ultimately making Diia.AI the single access point for all public services on the portal.

The assistant uses Google’s Gemini 2.0 Flash large language model, fine-tuned on Ukraine’s internal digital infrastructure.

It operates on a hybrid infrastructure: a local on-premise system within Diia’s secure perimeter, combined with cloud-based processing using Google technology. Importantly, data from state registries is not transferred to the cloud, ensuring privacy and security. In addition, all user queries pass through a guardrail filter that blocks potentially harmful or suspicious content, strengthening trust and safety."
