Spellbook provides AI-powered contract drafting and review inside Microsoft Word. Atticus manages your entire Ontario practice — matters, billing, trust accounting, and Canadian AI for all your client files. $149 CAD per lawyer per month.
Spellbook handles AI contract drafting inside Microsoft Word. Atticus manages your practice — from intake and conflict checking through matter management, trust accounting, and Canadian AI for your files.
Spellbook provides AI-powered contract drafting and review inside Microsoft Word. Ontario law firms need more: billing, trust accounting, matter management, client intake, and conflict checking across your whole practice, not just the document you're currently drafting.
While Spellbook is Canadian-founded, it focuses on commercial contract drafting AI. Atticus is built specifically for Ontario practice management — Ontario Limitations Act, LSO By-Law 9 trust accounting rules, and LSO AI guidance on using AI in Ontario legal practice.
Spellbook has no trust accounting module. Ontario lawyers still need separate software for LSO By-Law 9 trust accounting. Atticus includes mixed trust accounts, monthly reconciliation, and trust ledger reporting alongside AI-powered drafting assistance.
Spellbook AI works inside the Word document you have open. Atticus AI works across your entire practice — corporate records, agreements, correspondence, wills — extracting limitation period triggers, key dates, and parties regardless of document type or practice area.
Spellbook requires Microsoft Word and Microsoft 365. Atticus is a standalone web platform — no dependency on Microsoft licensing or Word add-in compatibility issues. Access your practice from any browser on any device.
Spellbook is a drafting add-in, and Ontario lawyers still need separate practice management, billing, and trust accounting tools. Atticus is $149 CAD per lawyer per month for the complete Ontario practice platform including AI.
