Summize provides AI contract summaries and key term extraction with Slack and Teams integration. Atticus manages your entire Ontario practice — matters, billing, trust accounting, and Canadian AI for all your client files. $149 CAD per lawyer per month.
Summize handles AI contract intelligence for business teams. Atticus manages your practice — from intake and conflict checking through matter management, trust accounting, and Canadian AI for your files.
Summize provides AI contract summaries and key term extraction with Slack and Teams integration for business teams. Ontario law firms need more: billing, trust accounting, matter management, client intake, and conflict checking. Atticus manages your entire Ontario practice.
Summize is a UK-founded 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.
Summize 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.
Summize AI summarizes contracts for business teams. Atticus AI reads all documents across your practice — corporate records, agreements, correspondence, wills — extracting limitation period triggers, key dates, and parties regardless of practice area.
Summize is a UK-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.
Summize charges per user for contract intelligence, and Ontario lawyers still need separate practice management, billing, and trust accounting. Atticus is $149 CAD per lawyer per month for the complete Ontario practice platform.
