All figures are illustrative estimates based on the inputs you choose — not measured customer results. The time-reduction percentage, reviewer rate, and per-page billing rate are your own assumptions; actual results vary by case complexity and document volume.
The ROI of AI in legal operations comes from three sources. Most firms focus only on the first — and undercount the real return.
The most visible savings. AI can sharply cut the time spent on first-pass document review. Multiply the hours your team recovers per case by your annual caseload and hourly burdened cost.
Illustrative example — not measured results
AI document processing can be treated as a billable litigation expense — just like court reporters, process servers, or expert witness fees. Firms set their own per-page rate and bill it to the case, directly offsetting the ProvaLens cost.

When your team recovers review time on every case, that time doesn't disappear — it goes toward intake, strategy, and new client development. By freeing up that time, ProvaLens can give your firm the capacity to support a larger caseload without adding headcount.

How a four-attorney personal injury firm could change the economics of document review
Illustrative example — a composite scenario, not measured customer results. All figures below are hypothetical.
The firm's two paralegals spent 15–20 hours per case reading medical records, building chronologies, and flagging inconsistencies by hand. With 90 cases per year and growing, document review was becoming the primary constraint on capacity — and the primary source of errors when things were rushed.
After adopting ProvaLens, the paralegals shifted from reading records to reviewing AI-generated summaries and timelines. ProvaLens processed each case in minutes, flagged possible treatment gaps and IME conflicts, and answered specific questions about the record via natural language search. First-pass review dropped from 18 hours to under 3.
The managing partner realized ProvaLens processing could be billed as a case disbursement at $1.00/page — the same rate previously billed for paralegal time on document review. For cases averaging 500 pages, that's $500 billed per case, versus $12 in actual ProvaLens cost. The subscription effectively paid for itself by the third case of each month.

"We're billing the cost back to clients anyway. ProvaLens is the first tool we've bought that actually makes us money."
