Frequently Asked Questions
No. This is the critical distinction between consumer AI (like ChatGPT) and enterprise legal AI. Platforms like Spellbook and Definely operate under strict SOC2 Type II compliance. They guarantee, contractually and technically, that your proprietary legal documents are never used to train the baseline public models.
While both have auxiliary web interfaces or PDF capabilities, their primary value proposition and deepest integration exist explicitly inside the Microsoft Word ecosystem, which remains the undisputed operating system of the global legal profession.
