Instead of spending hours redlining third-party paper, you can get a fully marked-up Word document back in minutes. The core of the platform is its ability to learn and enforce your specific negotiation playbook at scale. It codifies your firm's approved positions and historical edits, creating a source of institutional memory that prevents compliance drift.
