Since launching Spellbook three years ago, and scaling to over 3,400 law firms and in-house legal teams as customers, we’ve heard one big piece of recurring feedback: “I want AI to sound more like me. I want it to understand my style and preferences.”

Fine tuning was an alright technique two years ago, but today lawyers don’t want a tool fine-tuned on all of law. They want a tool that deeply understands their own preferences.

Today, we’re launching Library at Spellbook—an answer to this plea and a way for transactional lawyers to power AI with their own knowledge and precedents, helping it draft and review like they do.

Library will soon power many contract review & drafting features across Spellbook.

Our first feature powered by Library is Smart Clause Drafting: the fastest way to find and reuse language from your past work—right in Word.

Good Clauses Shouldn’t Be Hard to Find

Every transactional lawyer knows this frustration: you need a particular clause for a SaaS agreement, and you know you saw a great one last month. But where was it? 

You end up interrupting your flow to spend 10 minutes digging through folders, opening documents, and skimming through hundreds of pages to find what you’re looking for. And even when you find it, it can be tedious to massage the language to fit the new deal.

Put Your Deal History to Work

Smart Clause Drafting changes that by enabling you to access your entire document history from a simple search experience directly in Word. Ask for what you need in plain language, and instantly see clauses that match your current deal—not just keyword matches from random documents. When you find the right clause, Spellbook automatically massages the language to fit your new deal.

Connect Documents for Indexing

Connect to OneDrive or Dropbox, or directly upload files to Spellbook. We’ll ingest, analyze, and index your contract language for search.

Search and Insert Relevant Clauses 


When drafting, use the clause search to find language from your past work, and insert it directly into your current contract.

 

Automatically Adapt Clauses to Fit

Spellbook helps revise the inserted clause to match the style, structure, and context of your current agreement.

 

Smart Clause Drafting is just the beginning for Library. As Library continues to evolve, all of your work with Spellbook will be grounded in your institutional knowledge—personalized, precise, and aligned with your practice.

 

Shifting from the Era of Global Tuning to Preference Learning

Our bet at Spellbook is that over the next couple of years, AI providers will shift from the strategy of tuning one global model for legal work, to personalizing systems for individual firms and users. Library is just the beginning of that shift for Spellbook.
