Two of the best-funded AI platforms for plaintiff firms, compared from their own websites and press releases. Where a fact could not be sourced, we say so instead of guessing.
EvenUp's site describes a "Claims Intelligence Platform" built on a proprietary model it calls Piai, trained on what it says is the largest personal-injury dataset. Named products include PLAAS (Pre-Litigation as a Service), Communication Agents, Medical Management, AI Drafts, Express Demands and Expert Demands, MedChrons, Companion (an assistant with Lexis+ and Protégé integration), Case & Negotiation Prep, Settlement Repository, and Executive Analytics. The site says firms can "choose instant AI demands or legal-reviewed demands based on case type," and cites 2,000+ personal-injury firms, roughly 10,000 cases processed per week, and $10B+ in damages claimed (evenuplaw.com).
Supio's homepage lists Chronologies, Demand Letters, Case Ledger, Litigation Drafting, Supio Intake, and Supio Agent, which it describes as "the AI agent that works across your firm — every case, every role, all at once" (supio.com). Its July 2026 half-year release says Supio Agent launched in May 2026, Supio Intake runs "full intake conversations 24/7," the customer base more than doubled in the first half of 2026, and integrations include Westlaw Advantage, Litify, and Smokeball (Supio press release, July 13, 2026). Its Series B announcement emphasized "specialized AI with human expert verification" as its accuracy approach (BusinessWire, April 30, 2025).
| Dimension | EvenUp | Supio |
|---|---|---|
| Core wedge | Demand letters, expanded into pre-litigation platform (PLAAS) | Case intelligence across chronologies, demands, ledger, drafting, intake; "agentic" positioning |
| Target market | Personal-injury firms (site copy) | Plaintiff law and mass torts (site copy) |
| Medical chronology | Yes: "MedChrons" and "Medical Management" | Yes: "Chronologies" |
| Human review of output | Offers "legal-reviewed demands" as an option alongside instant AI demands | Describes "human expert verification" in funding materials |
| Legal research tie-in | Companion integrates with Lexis+ / Protégé (site); RELX's venture arm invested in Series E | One-click Westlaw Advantage integration (Apr 16, 2026); Thomson Reuters Ventures is an investor |
| Intake automation | Communication Agents | Supio Intake (24/7 intake conversations) |
| Security claims | "SOC2-audited and HIPAA-attested" | "SOC II Type II certified," HIPAA, PHIPA, GDPR; data "never trains foundation models" |
| Funding | $385M total; $150M Series E at $2B+ (Oct 2025) | $91M total; $60M Series B (Apr 2025) |
| Published pricing | None | Plan shapes only, no dollar figures |
| Free trial | Not published; demo-led | Not published; "many firms begin with a pilot on a handful of cases" |
Supio publishes the structure but not the numbers. Its pricing page offers a "Case Subscription" ("ideal for larger firms wanting predictable cost at a better value") and "Unlimited Firm Access" ("lowest per-case cost, unlimited cases"), both with "unlimited usage, unlimited users, unlimited pages" and "no lock-in contracts or platform fees" (supio.com/pricing). Its LawNext directory listing says "we offer firm-friendly pricing by case based on volume" (LawNext). Third-party estimates of $150–$400 per user per month circulate, but the source that publishes them labels them "market estimates for comparable PI-focused AI tools, not publicly published" tiers (ProPlaintiff, April 2026). Full breakdown: What Supio actually costs in 2026.
EvenUp publishes nothing. Third-party estimates range from $500–$2,000 per month for most PI firms (AI Vortex, April 2026) to $200–$500+ per user per month (ProPlaintiff, April 2026); both sources state EvenUp has not confirmed them. A competitor's analysis describes a per-demand base rate with add-on surcharges, which we treat as a competitor claim rather than a fact (LegalTechMag, July 2026). Full breakdown: What EvenUp actually costs in 2026.
Medical-malpractice cases are won and lost on standard of care, causation, and the exact page of the chart that proves it. Neither EvenUp nor Supio publishes a med-mal-specific product line, physician review of output, or a per-case price a solo attorney can plan around. Both accept med-mal matters; their published tooling is organized around PI volume.
MedLegal AI is the option we build, so weigh this paragraph accordingly. It is designed for medical-malpractice work on either side (plaintiff or defense), every finding is cited to the record page, output is reviewed by a practicing physician, and pricing is published: a free account with the first 3 case analyses free and no credit card, $19 per case pay-as-you-go, Pro at $49/month, Professional at $249/month (5 seats), and Firm at $499/month (20 seats) (pricing). It is not a demand-letter factory or a case-management system, and firms doing high-volume PI will likely still want one of the two platforms above.

No dollar figures from either. Supio describes two plan shapes with unlimited users and pages and no lock-in contracts; EvenUp has no pricing page. Third-party estimates exist for both and neither vendor has confirmed them.
EvenUp started with AI-drafted demands and grew into a pre-litigation platform for PI firms. Supio positions itself as an agentic platform for plaintiff and mass-tort firms with a Westlaw Advantage integration.
Neither publishes a med-mal-specific product line. For cases that turn on standard of care and causation, a physician-reviewed, page-cited tool with published pricing is a reasonable alternative or complement. Demo on your own records first.
Both make HIPAA and SOC 2 claims on their own sites. Ask each for a signed BAA before uploading protected health information.
