SwiftLaw vs. Spellbook

Spellbook is an AI contract drafting assistant that runs as a Microsoft Word add-in, popular with smaller firms for clause-level suggestions and contract review inside the document.

SwiftLaw is a full matter platform: intake, research, multi-document drafting, negotiation, and attorney sign-off run as one pipeline — with the same native Word fidelity, plus everything around the document.

When to choose Spellbook

Consider Spellbook if individual lawyers want lightweight clause-level help inside Word on single contracts, with minimal change to how the team works.

When to choose SwiftLaw

Choose SwiftLaw when the work is bigger than one document: fund launches, deals, and contract portfolios that need multi-document consistency, research, review gates, and a record of every decision — while keeping native Word output.

What is the main difference between SwiftLaw and Spellbook?

Scope. Spellbook assists a lawyer drafting inside a single Word document. SwiftLaw runs the matter around the documents: a full document set drafts from a term sheet, redlines run against your playbook, research is citation-backed, and every output passes an attorney gate with an audit trail.

Does SwiftLaw produce real Word documents like an add-in does?

Yes — output is native .docx with tracked changes in a Word-grade editor, not text to copy out of a chat window. The difference is everything around the document: intake, multi-document pipelines, validation gates, and reporting.

Who is each product built for?

Spellbook is popular with solo practitioners and smaller firms working contract by contract. SwiftLaw is built for teams running matters — fund managers, in-house legal teams, and firms that need whole document sets produced, reviewed, and recorded as one workflow.
