Illustrative estimate - a directional figure for scenario framing, not a measured benchmark. Do not read these as measured per-vendor results.

Across eight legal workflows, the dataset shows a before-and-after time split with AI assistance layered in. Directionally, the largest gains cluster in document-heavy tasks: document summarization drops from 2.0 to 0.7 hours (65%) and e-discovery review from 8.0 to 3.2 hours (60%), while client communication moves less, from 1.8 to 1.3 hours (28%). This suggests AI compresses review and synthesis time more than relationship-driven work, pointing to triage and first-pass review as the more defensible near-term deployment, with lawyers retained for judgment calls and client-facing work.
