Redlines, Reviewed by Machine

Automated review is good at coverage and bad at judgment. It will reliably tell you that an indemnity clause is missing a carve-out you usually require. It will not tell you whether this counterparty, in this deal, is going to accept it.

Use it for the first pass, never the last

The productive placement is early: run the document, get a list of deviations from your playbook, and hand a human a prioritized starting point. The unproductive placement is late — treating the tool's silence as approval, which is how a clause nobody read reaches signature.

• Write the playbook first; a review tool without defined standard positions has nothing to compare against.
• Keep a reviewer accountable per document, by name.
• Log the tool's misses — they tell you where the playbook is ambiguous.
• Never let a confidence score substitute for a decision.

The playbook is the real asset

Most of the value firms attribute to review software comes from the exercise of writing down their standard positions — fallback language, acceptable ranges, escalation triggers. That artifact keeps working when the vendor changes, and it makes junior lawyers useful faster than any tool does.

Automation is leverage on a standard you already wrote down. Without the standard, it's just faster guessing.

Evaluated that way, the question stops being which product to buy and becomes whether the firm has articulated what it actually wants in a contract. Firms that can answer that get value from almost any competent tool. Firms that can't get expensive dashboards.
