Designing a seamless Microsoft Word plugin to streamline contract review for legal professionals

Problem Statement
Legal professionals waste valuable time reviewing contracts manually, often repeating work and missing key issues. Existing tools are too disruptive or fail to integrate smoothly into their preferred working environments, especially Microsoft Word.
