Exceptional understanding of EU legal vocabulary. Natural Spanish/French. Fast.
Highly structured summary. One minor translation slip on legal terms.
Outstanding analysis and deep contextual extraction. Slower response.
Methodology note. Each prompt was run three times in separate sessions, with no system prompt, at UTC 09:00. The score is the median of three reviewers blinded to the tool. See full methodology.
