Lexion provides AI-powered contract intelligence and metadata extraction for in-house teams. Atticus manages your entire Ontario practice — matters, billing, trust accounting, and Canadian AI for all your client files. $149 CAD per lawyer per month.
Lexion handles AI contract intelligence for in-house teams. Atticus manages your practice — from intake and conflict checking through matter management, trust accounting, and Canadian AI for your files.
Lexion provides AI-powered contract metadata extraction and obligation tracking for in-house teams. Ontario law firms need more: billing, trust accounting, matter management across all practice areas, client intake, and conflict checking. Atticus manages your entire Ontario practice.
Lexion is a US-focused AI contract intelligence platform. Atticus is built specifically for Canadian and Ontario legal context — Ontario Limitations Act, LSO By-Law 9 trust accounting rules, Canadian case law references, and LSO AI guidance on using AI in practice.
Lexion has no trust accounting module. Ontario lawyers using Lexion for contract management still need separate software for LSO By-Law 9 trust accounting. Atticus includes mixed trust accounts, monthly reconciliation, and trust ledger reporting.
Lexion AI reads contracts for in-house teams. Atticus AI reads all the documents across your practice — corporate records, agreements, correspondence, wills — extracting limitation period triggers, key dates, and parties regardless of practice area.
Lexion is a US-based platform. Atticus stores all Ontario client files and trust records on Canadian servers by default — aligned with Law Society of Ontario guidance on cloud storage of client confidential information.
Lexion charges a per-user subscription for contract intelligence, and Ontario lawyers still need separate practice management, billing, and trust accounting software on top. Atticus is $149 CAD per lawyer per month for the complete Ontario practice platform.
