EvenUp vs Eve

The short version

EvenUp and Eve are both well-funded AI companies selling to plaintiff firms, and both now describe themselves as more than a drafting tool. EvenUp is PI-only and has moved toward doing pre-litigation work for firms. Eve sells an AI system that a firm's own staff run, and it markets several practice areas, including employment. The two are also opponents in a federal trade secret suit, which buyers ask about, so we cover it below with its current status.

Products and practice areas

EvenUp sells demands (Express and Expert), MedChrons, Medical Management, the Companion assistant, Communication Agents and executive analytics. Its Pre-Litigation as a Service offering, launched in May 2026, adds EvenUp's US-based case managers who run claim setup through carrier negotiation. EvenUp says it serves 2,000+ PI firms. Its pages name personal injury only.

Eve (the company's legal name is Butler Labs, Inc.) launched EveOS in June 2026. Its site describes agents that draft demands, discovery and motions and chase records; an auditor that reviews active matters nightly for injuries, treatment gaps and next steps; a voice intake agent; and an analyst for firm-level questions. Eve's site lists personal injury, labor and employment, medical malpractice, Social Security disability and workers' compensation, and claims 1,200+ customers. Its employment page covers charge drafting, demand letters and discovery for employment firms.

If your firm does employment work, that difference matters: EvenUp does not market employment, and Eve does.

Integrations

EvenUp's integrations page names Litify, SmartAdvocate and CASEpeer, plus SharePoint, Google Drive and Dropbox, and says setup has no fee. Eve has a dedicated Clio integration page; its home page says it works with case management systems but names none. If you run Filevine or Needles, ask both vendors how cases and documents move, and whether the AI's work writes back to your system.

The lawsuit, stated carefully

On September 26, 2025, EvenUp sued Butler Labs (Eve) in the Northern District of California, case 4:25-cv-08199-YGR, under the Defend Trade Secrets Act. EvenUp alleges that Eve recruited EvenUp employees to obtain confidential information, and that a former employee downloaded more than 900 documents, including pricing models, customer lists and sales data, before joining Eve. These are allegations. No court has ruled on their merits, and we found no public statement from Eve about the suit.

The case is assigned to Chief Judge Yvonne Gonzalez Rogers. A June 2026 docket entry referenced an arbitrator's temporary injunction against one Eve employee. As of October 16, 2026, EvenUp had filed its reply in support of a motion for a preliminary injunction, which was pending. Separately, AI.Law sued Eve for patent infringement in June 2026, also in the Northern District of California; that suit is also unresolved.

For a buyer, the practical step is to ask Eve how it would serve your firm if a court restricts any product or staff, and to read both companies' data handling terms.

Pricing

Neither publishes a price. EvenUp describes case-based pricing; a competitor's page estimates about $300 base per demand, more with add-ons. Another competitor's page estimates Eve at roughly $100 to $500 per user per month. Both figures are estimates from companies that compete with them. Ask each vendor for a written quote on the same caseload, and ask how cases that never reach a demand are billed.

Which one fits which firm

Choose EvenUp if you are a PI firm that wants work delivered, wants the option to outsource pre-litigation, or runs Litify, SmartAdvocate or CASEpeer.

Choose Eve if you want an AI system your staff run across the case, if you handle employment or mixed dockets, or if you run Clio.

Where PlaintiffStack fits

PlaintiffStack is case management with AI built in, so it replaces the case system rather than sitting on top of one. It is $250 per case with every app included; AI usage is billed separately, and each tool shows an estimated cost before it runs. California PI, workers' comp and employment ship with their own phases, case tools and morning checks, including an employment chronology of protected activity and adverse actions. It reads searchable PDFs, Word and text files only; there is no OCR yet, so scans and faxes are not read.
