Browse the organisations tracked by the PLI Observatory. Each profile shows a decade of linguistic measurement across ten PRISM™ dimensions.
Each dot is an organisation. The horizontal axis shows the current PLI score. The vertical axis shows drift from baseline (2015–2019 average). Click any dot to open the full profile.
Within each sector, organisations are ranked by how far their language has shifted from baseline. The steepest declines appear first.
AI-assisted writing is reshaping public communication in every language, every sector, every country. The Public Language Index tracks that change. The corpus currently spans seven languages and ten sectors, but our goal is to cover all 24 official EU languages. Every document collected strengthens a baseline that grows more valuable over time, creating a permanent record of how institutions sounded before generative AI entered the creative process.
