EvenUp vs Supio

The short version

EvenUp and Supio are the two names most PI firms hear first when they shop for AI. Both started with the document work that eats a pre-litigation team's week: medical records, chronologies and demand letters. By 2026 both were selling much more than that, but in different directions. EvenUp moved toward doing the work for you. Supio moved toward an agent your own team runs inside the system you already have.

If your firm wants fewer people touching each file, EvenUp's direction will appeal. If your firm wants its own staff to move faster without changing case management systems, Supio's will.

How they differ in approach

EvenUp was founded in 2019 and sells a suite it calls a Claims Intelligence Platform. Its products include Express and Expert Demands, MedChrons, Medical Management, an assistant called Companion, Communication Agents that call and text carriers and providers, and executive analytics. In May 2026 it launched Pre-Litigation as a Service (PLAAS), which pairs its software with EvenUp's own US-based case managers for claim setup, treatment tracking, records retrieval, demand preparation and carrier negotiation, with lien resolution as an option. EvenUp says it is used by 2,000+ PI firms and, as of May 2026, by 30% of the top 100 PI firms. Its marketing names personal injury only.

Supio is based in Seattle. Its 2025 Series B release described AI paired with human expert verification for PI and mass tort firms. In May 2026 it launched Supio Agent, which works at the case, caseload and firm level with attorney oversight, and Supio Intake, a 24/7 intake agent that sends structured data to your case management system. Supio says it reads from and writes back to your existing system, with no migration required. It also powers the document analysis and first drafts behind LitifyAI Instant Demands, which Litify launched in June 2026.

Records, chronologies and demands

Both products build chronologies from medical records and draft demands. The practical differences are elsewhere:

• Research. EvenUp's Companion includes Lexis+ with Protégé after a September 2026 alliance with LexisNexis. Supio connects to Westlaw Advantage through Thomson Reuters, which is also an investor.
• Integrations. EvenUp's integrations page names Litify, SmartAdvocate and CASEpeer. Supio's names Litify, SmartAdvocate, MyCase, CASEpeer, Smokeball, Jove and Neostella. Neither page names Filevine or Clio, so ask either vendor how it works with yours.
• Who reviews the output. With EvenUp you can buy the work done (PLAAS) or run the software yourself. With Supio, your team reviews and approves what the agent produces.

Both vendors make strong claims about outcomes. Those numbers are self-reported; ask for references at firms your size and case mix.

Pricing and contracts

Neither publishes a price. EvenUp describes its pricing as case-based. A competitor's comparison page estimates EvenUp demands at about $300 base and $500 to $800 or more with add-ons; treat that as an estimate, not a quote. Supio sells by quote. Per-case pricing can charge for files that never reach a demand, so ask each vendor how a case is counted and what happens to cases that drop.

For a fair comparison, send both vendors the same ten closed files and ask for a written price for that volume. Our AI demand letter cost guide walks through what to ask.

Which one fits which firm

Choose EvenUp if you are a PI firm that wants output delivered, wants to hand pre-litigation work to an outside team, or already runs Litify, SmartAdvocate or CASEpeer and wants a well-funded vendor with a large PI customer base.

Choose Supio if you want an agent your own staff drive, run mass torts, use one of the systems on its integration list, or value Westlaw-backed research inside the same tool.

Both are PI-first. If a meaningful share of your docket is workers' comp or employment, neither markets a California WC workflow. For a three-way view that adds Eve, see EvenUp vs Supio vs Eve.

Where PlaintiffStack fits

PlaintiffStack is a third option for a different buyer: a firm that wants case management and AI in one system rather than an AI layer on top of another vendor's. It costs $250 per case with every app included and no monthly fee; AI usage is billed separately, and each tool shows an estimated cost before it runs. It ships California PI, workers' comp and employment practices. Agents propose facts, deadlines and tasks for a person to accept, and drafts cite the page each fact came from. It reads searchable PDFs, Word and text files only: there is no OCR yet, so scanned records and faxes are not read, which matters if your records arrive as scans.
