Complex government documents may confuse citizens, making it difficult to access services such as pensions or benefits. This work uses GenAI to rewrite these texts in plain language, maintaining legal accuracy while increasing clarity. Focused on the Service Pages of Italy's National Institute of Social Security portal, which serves 45 million users, AI-generated versions received strong user preference over the original texts, enabling the Institute to communicate inclusively and at scale.

Initiative overview

Clear and accessible communication is essential for ensuring that citizens can effectively navigate public services. This work examines the use of generative AI models to simplify administrative texts on the INPS, Italy’s National Institute of Social Security, web portal, which provides nearly 500 digital services related to pensions and welfare. As Europe’s largest welfare institution, INPS serves approximately 45 million citizens, making the clarity of its service descriptions crucial for accessibility and user experience.

INPS has been running a structured simplification programme aimed at making its content understandable to users with a middle-school education level. To date, over 700 texts have been manually simplified, using the Gulpease index to measure readability. The average score improved from 57 to 64, reflecting a substantial increase in accessibility.

Currently, INPS relies on a manual process to simplify the language of its Service Pages, a time-consuming and resource-intensive approach that requires specialised expertise. The need for clearer bureaucratic language has been recognised in Italy for decades. A 2002 directive, still in force, states that “all texts produced by administrations must be designed and written to be understood by those who receive them.” Despite this, institutional communication often remains complex, limiting citizens' ability to fully understand and access essential services.

While simplification enhances transparency and public trust, a major challenge is maintaining the legal precision required for official documentation. This work explores how Large Language Models (LLMs) can support INPS in transforming its manual simplification process into a semi-automated system that is both efficient and scalable. The goal is to develop a solution that can process large volumes of text while ensuring readability, accuracy, and compliance with legal standards.

To achieve this, the research establishes an evaluation framework based on text metrics and conducts user surveys to assess the accessibility and quality of AI-generated text compared with original and manually simplified versions.

Looking ahead, the potential for refining and expanding this approach is substantial. Possibilities include generating pre-simplified texts directly from legal norms, introducing a compliance-evaluation framework, and developing collaborative workflows in which AI and human experts iteratively refine simplifications, combining automation with expert oversight.

The experimentation on text simplification has been developed as a prototype and has successfully passed the evaluation stage. It is now transitioning into an operational business process within INPS and its technology partners, integrating a graphical interface to support a human-in-the-loop collaborative workflow.

Results, outcomes and impacts: The AI effectively simplifies text, delivering expert-level results in a fraction of the time. Its robust metrics framework accurately evaluates various aspects of simplification. A large-scale survey, including A/B testing with 1,620 participants, confirmed the AI’s effectiveness. AI-generated text was preferred to the original text in more than 70% of responses and outperformed the original across all metrics, scoring significantly higher in fluency (+14.1%), readability (+13.5%), clarity (+11.11%), and engagement (+12.3%). These findings highlight key benefits: scalable AI-driven simplification for public administration, improved accessibility and seamless integration into broader communication strategies. Challenges and lessons learned: The main challenge was simplifying administrative texts while preserving full semantic and legal completeness. Optimising readability metrics alone risked losing essential information or overestimating real user benefit. Initial closed-question comprehension tests proved unreliable, as users could often “guess” correctly. We therefore shifted to large-scale A/B testing comparing original, human-simplified and AI-simplified versions. Results showed a clear and consistent user preference for simplified texts, validating impact empirically rather than through metrics alone. A key lesson is that analytical indicators are necessary but insufficient: large-scale user validation is crucial. Another lesson is that human-in-the-loop oversight is indispensable to ensure legal reliability and institutional accountability. Success requires strong governance, multidimensional evaluation and rigorous user testing.
