Opus 2 is a transcription and hearings tool — not a practice management platform. Atticus gives Ontario solo and small firms full practice management, trust accounting, AI, and LSO compliance in one Canadian platform.
Opus 2 serves a specific niche — AI transcription for hearings and arbitrations. Ontario solo and small firm lawyers need a complete daily practice platform, not a standalone transcription service.
Opus 2 provides AI-powered transcription, annotation, and management of hearings and arbitration proceedings. It is not a practice management system. Ontario solo and small firms need billing, trust accounting, file management, conflict checking, and client intake — none of which Opus 2 provides. Atticus is built for managing your entire practice.
Opus 2 has no trust accounting functionality whatsoever. For Ontario lawyers, LSO-compliant trust accounting is not optional — it is a professional requirement. Atticus includes fully LSO-compliant trust ledgers, mixed trust accounts, and reporting as core features, ready from day one.
Opus 2 does not include billing, time tracking, or HST invoicing. Every client matter requires docketing, invoicing, and tax-compliant billing. Atticus handles all of this natively — integrated time tracking, HST invoicing, and CRA-compliant records — at $149 CAD per lawyer per month.
Opus 2 AI is optimized for transcription accuracy and hearing annotation. Atticus AI is built for Ontario legal practice: document drafting, file summarization, limitation period flagging, and LSO compliance checking. Purpose-built for the tasks Ontario practitioners perform daily.
Opus 2 is a UK-based company with data hosting that varies by deployment. Atticus stores all client data on Canadian servers by default — meeting PIPEDA requirements and Law Society data guidance without additional configuration or negotiation.
Combining Opus 2 with a separate practice management platform and billing system means multiple subscriptions, separate data silos, and no integration. Atticus delivers practice management, billing, trust accounting, and AI in one Canadian platform — one subscription, one workflow.
