American state legislatures have long served as the laboratories of democracy, but they have modernized unevenly. Generative AI is now testing that gap in real time. In January 2024, POPVOX Foundation's Representative Bodies in the AI Era: Volume 1 documented how Congress and parliaments abroad were beginning to adapt to AI, and flagged state-level adoption as a thread worth following.
This report does three things.
First, it assesses state legislative adoption against the approaches, use cases, and institutional timeline outlined in Representative Bodies in the AI Era: Volume 1. The central finding is that state legislatures are simultaneously ahead of and behind the trajectory Representative Bodies anticipated, depending on which dimension is measured. A handful of domain-constrained platforms, including Iowa's Legible and Arizona's Skywolf, have reached the medium-term integration Representative Bodies projected years out. At the same time, most legislatures have not completed the basic immediate-phase work of issuing use guidelines or funding experimentation, and the most advanced implementations documented in this research are frequently the product of individual legislators or staff members rather than institutional strategy. Where formal capacity is thin, adoption does not disappear; it becomes privatized, improvised, and unevenly distributed.
Second, it documents how legislators and staff are actually using AI across twenty-two states, creating an initial field-based inventory of state legislative AI adoption. The unevenness of AI adoption this report documents traces directly back to four capacity dimensions this report examines: people, institutional knowledge, the broader network of relationships extending past the legislature's formal borders, and technology readiness. Thin staffing leaves offices no bandwidth to evaluate tools, so Microsoft Copilot becomes many staffers' default first experience with AI and, by several accounts, their most discouraging one. Institutional knowledge in state legislatures still lives mostly in individual memory rather than documented systems, leaving little for AI-assisted work to draw on and nowhere for training to live. Legislatures depend heavily on the executive branch, peer states, and outside organizations to fill research and drafting needs the institution has not built internally, a dependency now repeating itself in AI governance. Finally, technology readiness — digitized records, procurement processes built for AI, and clear governing policy — determines the ceiling on what any tool can do, regardless of how powerful or well-designed it is.
Third, it examines what those adoption patterns reveal about legislative capacity itself and proposes additional dimensions for assessing whether representative institutions are equipped to adapt to rapid technological change. This report's findings indicate that traditional political science comparative legislative capacity metrics of salary, session length, and staff numbers are no longer adequate to assess legislatures' ability to adapt to changing conditions. Section 5 proposes additional dimensions for assessing legislative capacity as part of a new Legislative Adaptive Capacity Index (LACI), including demand capacity, knowledge infrastructure, network capacity, and technology readiness. While beyond the scope of this paper, the prospective framework may serve as a guide for what legislatures should build, not only a way to measure what they already have.
Section 6 carries this into thirteen recommendations, adapted from Representative Bodies and organized around three priorities:
- Building the institutional foundation
Treating data as a strategic resource, issuing agile AI guidance, customizing AI tools, and giving technology capacity an institutional home
- Moving the adoption curve
Initiating early, phasing integration, investing in upskilling, and engaging resistance on its own terms
- Governing what adoption produces
Retaining human oversight, treating caucus AI procurement as an institutional rather than partisan decision, and deepening interstate and cross-branch collaboration
The choices state legislatures make on these fronts over the next several sessions will shape whether AI expands their capacity to govern or deepens the asymmetries this report documents.
