From first draft to final signature, Spellbook covers your entire contract workflow
Spellbook drafts from your own precedents and clause library, so every agreement begins with language your firm already trusts. Your lawyers spend their time refining, not reinventing.
Spellbook flags risks, missing clauses, and off-market terms against your playbook right inside Word, turning the slow, low-value first read into a fast, high-confidence starting point.
Codify your house positions and preferred language once. Spellbook applies them on every review, so the work looks like your firm's regardless of who's at the keyboard and answers "is this market?" without the precedent hunt.
Spellbook Associate runs the multi-document work that eats weekends: data room reviews, financing packages, and disclosure schedules. It extracts and compares provisions across hundreds of documents and surfaces inconsistencies before the closing table.
Review and draft in Microsoft Word, then pull from the document repositories your team already relies on.
