CaseMark vs Supio: pricing, features and which to choose

CaseMark builds AI for litigation teams, court reporters and litigation support companies. It first became known for AI deposition summaries, and its main product is now Para, which it describes as an AI colleague for legal teams; Para was formerly called CaseMark Operator. Its users include personal injury and commercial litigation firms, paralegals, legal nurse consultants and court reporting agencies that resell summaries under their own brand. CaseMark says it is SOC 2 Type II audited and HIPAA compliant, encrypts data with AES-256 at rest and TLS 1.2 in transit, and does not use customer data to train models on its Pro and Enterprise plans.

Para takes requests in email, Microsoft Teams, Slack, meetings and its web app, and it records meetings on Zoom, Google Meet, Teams and Webex. It connects to Clio, Smokeball, Google Drive and Microsoft 365 for documents. Teams assign it work such as reviewing medical records, drafting demand letters, writing motions for summary judgment or preparing deposition bundles, and Para keeps working after hours, then reports back with drafts and questions. CaseMark says Para checks with an attorney before anything leaves the firm and that work going to a court or client goes out under an attorney's name. Projects, automations, skills and meetings are included on every plan.

CaseMark's strengths are low entry prices, pay-per-file summaries with no subscription, page-level citations, multiple deposition formats, white label options for court reporters and Para's ability to work in email and chat tools lawyers already use. Its weaknesses are a smaller company than the major legal platforms, no case management of its own and inconsistent published rates for some summary types. Filevine and Litify include deposition and medical AI inside full case management. EvenUp and Supio focus on personal injury demands and case analysis. CoCounsel and Harvey offer broad legal AI for research and drafting. Choose CaseMark if you want affordable, cited summaries or an AI colleague without changing systems.

Supio is a Seattle legal AI company focused on personal injury and mass tort plaintiff firms. It emerged from stealth in August 2024 with a $25 million Series A, then announced a $60 million Series B on April 30, 2025, bringing reported total funding to $91 million. Sapphire Ventures led the Series B, with Mayfield and Thomson Reuters Ventures participating. Supio is built for firms processing substantial case records and portfolios, rather than for general legal question answering. Its named workflows include chronologies, demand letters, case ledgers, litigation drafting, intake, and agentic case operations. The company describes specialized, purpose-built AI models and human expert verification, but does not name the foundation model vendors behind the service.

Supio organizes case preparation around document intelligence and structured outputs. Case Economics, Case Signals, and the Drafting Suite address different stages of reviewing records and producing work product. Teams can create chronologies, demand letters, case ledgers, and litigation drafts. Supio Intake conducts intake around the clock, scores leads, and writes structured case data to a case-management system. Supio Agent, launched in May 2026, plans and executes finished work with attorney oversight at case, portfolio, and firm levels. Connectors support integrations and two-way CMS synchronization, while a Westlaw Advantage connection was announced in April 2026. The practical design is a shared operating layer for case preparation, lead handling, and drafting, rather than a single document-generation utility.

The main buying risk is opacity around commercial and technical details. Supio does not publish dollar prices, named model vendors, API limits, retention schedules, or self-hosted deployment options. EvenUp is the closest specialist comparison, covering plaintiff-injury intake, treatment, demands, negotiation, discovery, and trial, with MedChrons combining AI and professional or nurse review. Filevine’s LOIS is broader case-management software that acts on matters, deadlines, documents, and appointments inside its system of record. Litify combines Salesforce-based practice management with agentic workflows and a Supio-powered damages assistant. Supio should be picked by plaintiff firms wanting dedicated case intelligence, intake, drafting, and portfolio automation, provided a custom quote and contract answer their integration and governance requirements.
