Eve is an AI workforce platform built for plaintiff firms — strong at intake, demand drafting, and discovery responses. Casefleet is a litigation workspace where every fact links to a citation and a source document, with agentic AI that works inside your case data rather than generating documents beside it.
Eve (Butler Labs, Inc.) is purpose-built for plaintiff law firms. Intake screening, demand letter generation, medical chronologies, discovery responses — all driven by AI, all designed to move PI and mass tort cases faster. It's adopted by 1,000+ plaintiff firms, rates 4.9/5 on G2, and has raised over $100M in venture funding. If your firm runs high-volume plaintiff work and your biggest bottleneck is drafting output, Eve is a serious product.
Casefleet is a different kind of tool. It's a structured litigation workspace where the fact is the atomic unit of a case. Every fact carries a date, links to issues and witnesses, and traces back to a citation in the source document you can open with one click. The AI doesn't sit beside your case — it works inside it, proposing facts, tagging sources, extracting entities, and drafting from your structured data. You review and approve every change.
The tradeoff is real: if you want a productized drafting pipeline for plaintiff PI work, Eve is built for that. If you litigate cases that depend on building a defensible fact chronology with hard citations — plaintiff or defense, PI or employment or criminal or family or complex commercial — Casefleet's data model and pricing transparency are hard to beat.

One note from the public record: in September 2025, EvenUp filed suit against Butler Labs (Eve) alleging trade secret misappropriation. That dispute is between two competitors and shouldn't drive your decision — but it's part of the landscape worth knowing.
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.
We are absolutely using the daylights out of the chat feature lately, and it's becoming my go-to legal AI. It seems to be getting better and better.
Casefleet starts at $30/user/month (annual) for the Starter plan and $75/user/month for Advanced AI, which adds Document Intelligence, AI Suggested Facts, full-text search, and unlimited documents. No seat minimums, no long-term contracts. Start a 14-day free trial with just an email.
Eve does not publish pricing. Independent estimates put it at roughly $100–$500 per user per month, with custom enterprise contracts and no public self-serve trial.
We'd point you toward Eve if:
If you litigate cases that go past the demand stage — employment, criminal, family, workers' comp, complex civil, plaintiff or defense — and your work depends on building a fact chronology with hard citations that holds up through trial, Casefleet's structured workspace and transparent pricing will serve you better.
Both use frontier models and both draft. The difference is what the AI is connected to. Eve produces documents you then fact-check. Casefleet's agentic AI works inside a structured case database — it proposes facts, tags sources, extracts entities, and drafts from the facts and citations already in your workspace, with you approving every change.
Casefleet's agentic drafting toolkit drafts demand letters, motions, summaries, and correspondence grounded in your case facts. What it doesn't ship is a productized, templated PI demand assembly line — that's Eve's core product.
Eve markets itself primarily to plaintiff law firms. Casefleet is used by plaintiff, defense, government, and corporate litigation teams across PI, employment, criminal, family, and complex civil matters.
