Supio vs EvenUp: Which PI Demand Platform Fits Your Firm
EvenUp and Supio both turn a personal injury case file into demand packages and medical chronologies, but they are built around different working models. EvenUp's public pitch is pre-litigation work, including a choice between instant AI demands and legal-reviewed demands, backed by a large verdict and settlement dataset. Supio's public pitch is one agent working the whole case from intake through trial, with firm-level reporting and integrations into the case management system you already run. Neither publishes a price: both are "pricing on request" in our directory. If your firm lives on demand volume and wants a reviewed deliverable back, start with EvenUp. If you want your own staff working inside one platform from intake to litigation, start with Supio. Then test both on your own closed files.
Nearly every head-to-head page for this pair is written by a plaintiff-AI vendor, including one of the two companies being compared. That is not a criticism, it is just a conflict of interest, and it shapes what gets emphasized. LegalizeAI does not sell a demand product and takes no revenue share from either company, so this comparison sticks to what a firm can verify: what each vendor states on its own pages, what a third party reported, and what you still have to ask for in a demo. This is software evaluation, not legal advice.
What does each platform actually deliver?
EvenUp is built for personal injury firms. Its site describes a platform that spans the case lifecycle, from intake and treatment tracking through demands, negotiation, discovery and trial. The demand step is where it is best known. EvenUp says firms can choose instant AI demands or legal-reviewed demands depending on case type, and it points to a verdict and settlement dataset of more than 250,000 records as the basis for its valuations. The site also lists SOC 2 auditing and HIPAA attestation, line-level citations so you can check a fact against its source, and a figure of 10,000 cases processed weekly. That last number matches what the CEO told LawNext when the company raised its $150 million Series E, a round that Artificial Lawyer also covered.
Supio is built for plaintiff and mass tort firms. Its site describes a single agent that works at the case, caseload and firm level, covering demands, medical chronologies, case valuation, deposition preparation and trial exhibit organization. It connects to case management systems, document storage, email and phone tools, and QuickBooks, and it advertises Westlaw Advantage access through its Thomson Reuters relationship so citations can be checked against the law. Supio says every draft and chronology links back to its source document.
Both vendors say what they do in similar words: draft the demand, build the chronology, show the source. The difference is where each one puts its weight. EvenUp leads with the demand and the dataset behind the number. Supio leads with the agent and the firm-wide view. Our directory lists EvenUp and Supio under case intelligence, and Eve as a third plaintiff-side option if you are building a shortlist of three.
Service or software: how does each work day to day?
This is the question that decides most of the buying experience, and it is the one marketing pages blur.
With a service-leaning workflow, your staff uploads a case file, waits for a deliverable, and a reviewer on the vendor side has checked the output before it arrives. EvenUp's legal-reviewed demand option is the clearest public example of that model among the two. You are buying a finished work product with a human in the loop on the vendor's side, and your attorney still reviews it before it goes out under your name.
With a software-leaning workflow, your paralegals and attorneys operate the tool. They run the case through it, edit the output, and own the review. Supio describes this model: an agent your team works with, trained on your firm's templates and prior cases. You gain control and a closer fit to how your firm writes. You also take on the review work, so the savings depend on how fast your staff can check and correct a draft.
Neither model is better in the abstract. It comes down to who has the spare hours.
| Question | Service-leaning (EvenUp's reviewed option) | Software-leaning (Supio's model) |
|---|---|---|
| Who reads the draft first | Reviewer on the vendor side, then your attorney | Your staff, then your attorney |
| Best when | Demand volume is high and your team is the bottleneck | You want one system from intake to litigation |
| Main risk | You depend on vendor turnaround and cannot tune the style | You carry the editing time and the learning curve |
| What to test | Turnaround on your hardest file | Hours your staff spends correcting a draft |
Note that EvenUp also offers instant AI demands without legal review. A reviewed deliverable is a choice you make per case type, not something you get automatically. Ask which option applies to your caseload.
How do they handle medical records?
Medical records are the hard part of a PI demand. A real file runs to hundreds or thousands of pages, with duplicated bills, handwritten notes, treatment gaps and prior injuries hiding in the middle.
Both platforms say they turn records into structured chronologies. EvenUp's site describes interactive chronologies and a care timeline that tracks treatment status. Supio's site says its platform distills medical records, bills and police reports into structured insights and pushes them back into your case management system, so nobody re-keys the facts.
What neither claim tells you is how it behaves on bad records. Before you sign, run the same difficult file through both and check four things:
- Completeness. Does the chronology catch every provider and date, including the ones in the middle of a 600-page PDF?
- Gaps. Does it flag a six-week treatment gap or a prior injury that the other side will raise?
- Citations. Can your paralegal click from a statement to the page it came from? Both vendors say yes, so test it.
- Billing. Do the totals reconcile to the bills, or only to the summary?
One more point sits upstream of both products. Neither is a record retrieval service. If you are waiting weeks on records, the best demand tool in the world sits idle. Count retrieval time in your own timeline before you compare drafting speed.
What do firms report paying?
Nobody publishes a verified price for either tool, and our directory lists both as pricing on request. We will not print a number we cannot source, and you should be skeptical of any comparison page that does.
Here is what is on the record. Supio's page says it offers predictable pricing without page limits, demand-type tiers or edit fees. That is a claim about its own structure and a pointed one about EvenUp's, and EvenUp does not publish its terms, so you cannot check it from the outside. Treat it as a question for the quote: ask each vendor to put in writing how a demand is priced, whether edits or revisions cost extra, and what happens when a case type changes.
Questions to put in writing:
- Is pricing per seat, per case, per demand, or a firm-level contract?
- Do page counts, case complexity or demand type change the price?
- Are edits and regenerations included?
- Is there a minimum term, and what is the exit if it does not work?
- What does onboarding cost, and who does it?
The pricing guide on our site explains why most legal AI vendors gate their numbers and how to budget around a quote, in Legal AI Pricing: What 50+ Tools Actually Cost.
Which caseload fits which tool?
Here is how the fit tends to break down, based on what each vendor says about itself. This is a starting hypothesis, not a verdict.
A high-volume pre-litigation firm. If most of your cases settle at the demand stage and your constraint is the number of demands your team can finish, EvenUp's model of demands plus a verdict dataset plus an optional reviewed deliverable lines up with that problem.
A firm that litigates. If a meaningful share of your cases move into discovery and trial, Supio's pitch of intake through trial in one agent is aimed at you. Check how well its litigation tools handle your jurisdiction's practice before relying on that.
A mass tort or large-docket firm. Supio positions itself for mass tort as well as single-injury work. EvenUp's own pages are written about personal injury. If you run a docket of many similar claimants, ask each vendor how it handles that structure.
A small firm with a handful of demands a month. Neither product is obviously built for you, and a per-demand service may cost less than a platform contract. Our guide to EvenUp alternatives covers the service-versus-software split for lower volumes.
A firm already tied to a case management system. This is where the diligence is boring and important. Supio lists integrations with Litify, SmartAdvocate, MyCase, CASEpeer, Smokeball, Jove and Neostella on its integrations page, and invites you to ask if yours is missing. EvenUp lists an integrations product on its site, but we could not open a detail page listing specific systems, so ask for the list in writing. If your firm runs Filevine, neither vendor's public pages we reviewed named it, so confirm it directly rather than assuming.
How do Supio and EvenUp score on the points you can verify?
This scorecard rates each point by how much of it a buyer can confirm from public information, not by how good the product is. A good product with a thin public record scores low here on purpose, because a thin record means more questions for the demo.
| Criterion | EvenUp | Supio | What to verify |
|---|---|---|---|
| Demand drafting | Stated on its site; instant and legal-reviewed options | Stated on its site; editable drafts tied to firm templates | Output on your own closed file |
| Medical chronology | Stated on its site | Stated on its site | Completeness and gaps on a messy record set |
| Human review layer | Stated: legal-reviewed demands for certain case types | Not stated as a vendor-side service; staff review in platform | Who reads the draft before you do |
| Integrations | Listed as a product, specific systems not confirmed by us | Seven case management systems named, plus document and email tools | Your exact system, in writing |
| Security | States SOC 2 audited and HIPAA attested | States SOC 2 Type II certified, HIPAA, PHIPA and GDPR controls, data centers in the U.S., UK and Canada | The report itself, not the badge |
| Pricing transparency | Not public | Not public, but states no page limits or edit fees | Written terms for edits and demand types |
On security, the wording matters. EvenUp says "SOC 2 audited" and Supio says "SOC 2 Type II certified." Those are not identical statements, and SOC reports are issued by CPA firms under the AICPA's SOC suite of services. Ask each vendor for the current report, check the audit period and the scope, and read any listed exceptions. A badge on a marketing page is not the report. Our post on legal AI data security walks through that review.
What should you do before you sign?
A demo is a sales presentation. A pilot on your own files is the real test. Here is a plain process that works for either vendor.
- Pick three closed cases. One clean, one messy, one that went to litigation. You already know the outcomes, so you can judge the output.
- Run the same files through both platforms. Same records, same instructions, same reviewer.
- Time the review, not the draft. The draft arrives fast in both cases. The number that matters is how long your attorney takes to get it to a version they would sign.
- Check every figure. Medical totals, dates of treatment, provider names. One wrong number that reaches an adjuster costs more than the time you saved.
- Get the terms in writing. Pricing, edits, term length, data location, and what happens to your data if you leave.

FAQ
Is Supio or EvenUp better for small PI firms?
Neither is clearly built for a small firm, and neither publishes pricing, so you cannot compare cost without a quote. EvenUp's reviewed demand option suits a firm whose team is the bottleneck. Supio suits a firm that wants one platform from intake onward and has staff to work in it. A firm with only a few demands a month should also price a per-demand service before committing to a platform contract.
Does Supio write demand letters?
Yes. Supio's site describes AI-assisted demand letters as part of its pre-litigation features, alongside medical chronologies and case economics, and says every draft links back to its source document. Run it on one of your own closed files to judge whether the demand reads the way your firm writes.
How do Supio and EvenUp price?
Both are pricing on request, and our directory lists them that way. Supio's page says it offers predictable pricing without page limits, demand-type tiers or edit fees. EvenUp does not publish its terms. Ask each vendor to put in writing how a demand is priced, whether edits cost extra, the minimum term, and the onboarding cost.
Does either integrate with Filevine?
We could not confirm it for either one. Supio's integrations page names Litify, SmartAdvocate, MyCase, CASEpeer, Smokeball, Jove and Neostella, and says to reach out if yours is not listed. EvenUp lists integrations as a product, but we could not open a page naming specific systems. If your firm runs Filevine, get a written answer from both vendors before you pilot.
