Spellbook is the contract specialist on this list. It lives in Microsoft Word as an add-in with five functions: Review to redline and catch risks, Draft to write clauses or full agreements from AI or saved precedents, Ask for quick answers, Benchmarks to compare terms to industry standards, and Playbooks to apply your team's standards as automated checklists. Associate, its agent, works through multi-document matters such as a set of transaction documents with the lawyer in control. For in-house teams, newer features pull contracts in from email and Slack for a first-pass review and keep signed agreements in a searchable repository with renewal monitoring. Spellbook says 5,000+ legal teams use it and cites zero data retention with its LLM providers, SOC 2 Type II and HIPAA. There is a 7-day free trial, but pricing is custom and quoted per team size, and it does not do case law research.
