For years, lawyers have voiced a consistent complaint about AI drafting tools: “It doesn’t understand my style.” While AI has made strides in speed and efficiency, it has largely failed to mirror the nuanced preferences, structure and tone of individual legal practitioners.

Now, Spellbook—a leading player in AI-assisted contract drafting—may have cracked the code with its latest feature launch: Spellbook Library. This new functionality  enables lawyers to turn their past work into a rich, searchable knowledge base, giving the AI a smarter foundation for drafting and review. 

Smart Clause Drafting

At the heart of Library 1.0 is Smart Clause Drafting, a feature that surfaces relevant clauses from a lawyer’s own document history—and makes them instantly reusable.  No longer will transactional lawyers need to scour deal folders or email colleagues trying to dig up the perfect language.

Instead, Smart Clause Drafting allows users to:

  • Search for Clauses in Natural Language: Simply ask for what you need (e.g., “termination clause for software agreement”), and the tool pulls up relevant examples from similar documents—not just keyword matches.
  • Insert and Adapt Instantly: The selected clause is adapted to fit the current agreement’s style, structure, and language, minimizing editing and review time.
  • Realtime Syncing: Users can connect their OneDrive, Dropbox, or upload documents directly to Spellbook, creating a personalized clause repository that grows over time.

This approach turns years of institutional knowledge into a searchable, practical resource embedded directly in Microsoft Word.

 

Personalization Without Prompt Engineering

What makes Library 1.0 notable isn’t just the tech—it’s the shift in user experience. Rather than forcing lawyers to become prompt engineers or retrain models, Spellbook uses precedent-based search and contextual language adaptation to reflect how an individual (or firm) actually writes.

The result is language that sounds less like ChatGPT and more like the lawyer who’s actually responsible for the deal.

 

A Foundation for Future Features

Library and Smart Clause Drafting are the first in a series of personalization-focused improvements that Spellbook has on its roadmap. As the Library expands, the company says future features will help embed a firm’s entire knowledge base—style preferences, deal history, institutional standards—into every aspect of legal drafting and review.

For those already using Spellbook, Library is rolling out starting today. And for those still relying on Ctrl+F through old Word docs to find their best work, this may be the moment to take AI-assisted drafting seriously.
