SimpleLegal is an enterprise legal operations platform for corporate in-house legal departments — it tracks outside counsel spend, manages vendor relationships, and processes LEDES invoices. Atticus is built for Ontario law firms doing the actual legal work, billing clients, and managing trust accounts.
Atticus includes trust accounting built specifically for Ontario LSO By-Law 9 compliance. SimpleLegal has no trust accounting functionality — it manages legal spend from an in-house budget perspective, not law firm trust fund management.
SimpleLegal does not include practice management, client intake, conflict checking, billing for law firms, or AI document analysis for legal work. Atticus delivers all of these in a single platform at $149 CAD per lawyer per month.
Atticus AI is trained on Canadian and Ontario legal context. SimpleLegal provides spend analytics and legal operations dashboards — not AI-powered legal work product analysis, document review, or Ontario limitation period intelligence.
Atticus AI extracts key dates from your client documents and applies Ontario Limitations Act 2002 rules automatically. SimpleLegal has no limitation period tracking — it is a legal spend and operations platform for corporate clients.
Atticus is $149 CAD per lawyer per month for complete Ontario practice management including AI. SimpleLegal is an enterprise platform priced for large corporations — not designed for Ontario solo and small law firms.
