AI Analysis
●●●BangerWizardryBig BrainZero to One
3D UMAP visualization finds conceptually similar constitutional provisions across 188 countries.
Strengths
- •Gemini embeddings + UMAP projection enables semantic search beyond keyword matching
- •30k articles from 188 countries with country filtering and geopolitical bloc presets
- •Export result sets and shareable research views with comments for collaboration
Weaknesses
- •Legal researchers may need citation verification tools not mentioned in the demo
- •Niche audience limits broader adoption despite impressive technical execution
Category
Target Audience
Legal researchers, comparative law scholars, policy analysts

Post Description
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.
