I built this after noticing that existing tools for comparing constitutional law either have steep learning curves or only support keyword search. By combining Gemini embeddings with UMAP projection, you can navigate 30,828 constitutional articles from 188 countries in 3D and find conceptually related provisions even when the wording differs. Feedback welcome, especially from legal researchers or comparative law folks. Source and pipeline: github.com/joaoli13/constitutional-map-ai

Could you build this?
Yes The project uses Gemini API embeddings, off-the-shelf Python UMAP reduction, and standard 3D web libraries (like Three.js) to render parsed legal texts.
Discussion
4 comments analyzed.
Concerns raised: Constitutions fail without sufficient cultural and economic foundations, Rational design of legal frameworks doesn't work in practice, Surface-level documents are ineffective abstractions
Feature requests: Add historical constitutions from different eras (French Republics, U.S.S.R., imperial Brazil), Add temporal dimension to track semantic drift across political transitions, Filter for idealism vs pragmatism in constitutional design
