Supio is an AI platform purpose-built for personal injury plaintiff firms — medical chronologies, demand letters, and litigation drafting with human experts verifying every output. Casefleet is litigation software where you build and control the case yourself, with agentic AI inside the workspace. Plans start at $30/user/month with a 14-day free trial.
Supio is one of a small group of AI platforms built specifically for PI plaintiff firms — alongside EvenUp and Eve Legal. Its core products are AI medical chronologies, Instant Demands, and litigation drafting. Supio reports adoption by hundreds of firms across 27,000+ cases and over $1B in settlements. In April 2026, Supio announced a Thomson Reuters / Westlaw Advantage integration for connected legal research, and has launched Supio Agent, its agentic AI offering.
What sets Supio apart from the other PI-AI tools is human verification. Their pitch is that pure AI risks hallucinations on medical records, so human subject matter experts verify every chronology before delivery. That's a real safeguard — and a real cost and turnaround driver.
Casefleet is software, not a service. Every fact links through a citation to the source document. The AI proposes facts, tags sources, extracts entities, and drafts demand letters, summaries, motions, and correspondence — all inside the case file you control. There's no human-reviewer queue between you and your work product, but there's also no per-case service fee.
If you're an exclusively PI plaintiff firm and want medical-records-to-demand outsourced with human QA, Supio is built for that. If you want a workspace your team runs end-to-end across any practice area, Casefleet is built for that.

Worth weighing: pricing isn't public (sales call required), no self-serve trial, PI-only (you'd need a second tool for other practice areas), and modest review presence on G2/Capterra compared to more established legal software.
I have a very large network of legal nurses. What stood out to me was that we have control over reviewing and creating a chronology, versus other software that uses AI to do it. All the features of Casefleet were exactly what I was looking for.

Casefleet is the better choice if:
Both. Supio's customer-facing product is a software UI, but every chronology has human SMEs verifying the output before it's delivered. That distinguishes it from pure-software tools like Casefleet.
Yes. AI Suggested Facts, Document Intelligence, and the document reviewer build chronologies from medical records — see medical chronology software. The difference is your team is the reviewer, not a vendor's SMEs.
Yes — the agentic AI drafting toolkit drafts demand letters, motions, briefs, summaries, and correspondence grounded in your case facts. What it doesn't ship is Supio's productized, human-verified demand pipeline.
Supio does not publish pricing — a sales call is required. Casefleet's pricing is published: $30 Starter, $75 Advanced AI, custom Enterprise.
The Casefleet model is that you are the reviewer — per-record review of AI-proposed facts, batch review of bulk source operations, and a clean approve/edit/reject UI. Firms that want extra capacity bring in paralegals or legal nurse consultants directly via group permissions.
