What Legal Tasks Is AI Performing?
Top 20 legal tasks by AI usage percentage, based on O*NET task classification across global platforms.
Measured data - pre-processed from HAQQ's real Legal AI Index usage dataset (134,000+ data points across 30 countries) or HAQQ's own /50 cross-model legal benchmark.
HAQQ's usage data shows one task dominating the mix: reading and rewriting legal documents into specified languages accounts for 16.59% of AI-assisted legal work, more than five times the next-ranked task, monitoring regulatory compliance, at 3.10%. Below that pair, usage fragments into a long tail of narrower tasks (reviewing laws and policies, assessing liability, customs documentation) each under 3%. The pattern suggests translation and document reformatting are the clearest, most repeatable use case lawyers have found for AI so far, while higher-judgment tasks like liability determination stay far less concentrated.
