EvenUp cuts document drafting from 15 hours to 15 minutes with Claude

Overview

EvenUp, a legal technology platform for personal injury firms that has resolved more than 200,000 cases and secured more than $10 billion in damages for injury victims, built its AI Drafts product on Claude, with Opus 4.8 handling deep reasoning and consistency-checking, and Sonnet or Haiku handling everyday extraction from case records that can run 1,000-plus pages. Document drafting that previously took 8 to 15 hours of skilled paralegal work now returns as finished drafts in about 30 minutes, a roughly 99% time reduction, while settlement offers across EvenUp's customer firms rose 300% and one firm cleared a 45-day demand-writing backlog after drafting time fell from about a month to roughly ten minutes per case.

The challenge

A personal injury case runs on documents - demands, negotiation sheets, discovery responses, medical summaries - each of which has to be formatted correctly, factually airtight, and toned to match the firm. Before EvenUp, that was entirely manual: a paralegal worked through stacks of records that were weeks late and out of order, with the same visit sometimes documented three different ways by three different providers. One California firm ran its entire demand-writing function through a single person and carried a 45-day backlog; paralegals at an Ohio firm built medical chronologies and totaled bills by hand, taking 8 to 15 hours per case, forcing firms to choose between eating the hours or referring the case out.

The solution

EvenUp's AI Drafts reads each page of a case (often 1,000+ pages from a dozen providers) the most affordable way it can - real text, then standard OCR, then Claude's vision for scanned bills and checkbox forms - and sorts documents by type so the system only asks each page what it can answer. Every fact keeps a citation to its source page, duplicates are merged, and the record is settled once before drafting starts. Opus 4.8 sets the drafting blueprint (applicable legal rules, likely opposing arguments, the case's throughline) and checks it for consistency once; Sonnet then writes each section from that blueprint following state-by-state rules written in plain English. Everyday extraction runs on Sonnet or Haiku, reserving Opus for tasks where a subtly wrong argument could hide inside polished text. Every draft still ends with an attorney reading, checking, and signing it.

Reported business value

Drafting that once took 8 to 15 hours of skilled work now returns as finished drafts in about 30 minutes, a 99% decrease. Settlement offers across EvenUp's customer firms are up 300%. The California firm that ran all its demand writing through one person cleared its 45-day backlog, with demands that took a month now taking about ten minutes and attorney review moving 75% faster. An Oregon firm's drafting turnaround fell from months to days and its team reported 400% revenue growth in one year. Inside EvenUp itself, 200+ employees use Claude Enterprise and Claude Code is spreading through engineering.
