How much does AI demand letter software cost? 2026 prices and models

The short answer

Most of the larger AI demand vendors do not publish a price. EvenUp, Eve, Supio and the AI inside Filevine and Litify are sold by quote. Third parties estimate EvenUp's demands at about $300 base and $500 to $800 or more with add-ons, but EvenUp has not confirmed those numbers and moved to per-case pricing in 2025. At the published end, CaseMark lists medical summaries at $25 plus a cent a page, capped at $100, and some small-firm tools that once listed monthly plans, such as ProPlaintiff, now price by demo.

PlaintiffStack publishes this page and is one of the options in it. Its price is $250 per case with every app included, which covers case management as well as the demand tool, so it is not a like-for-like number with a demand-only service. AI usage is billed separately. Its other limits: California rules only, no OCR for scans and faxes yet, SOC 2 Type II and ISO 27001 in progress, and a young company.

Five ways vendors price demand letters

The pricing model shapes your bill more than the headline number does. Know which one you are being quoted.

1. Per demand. You pay each time a demand is drafted. Simple to budget per file, and you pay nothing for cases that settle early or never reach a demand. The risk is add-ons: expedited turnaround, extra records, revisions.
2. Per case. You pay once per case, whether or not it reaches a demand. EvenUp moved to this model in 2025, describing "one clear, predictable cost per case." It makes cost predictable but charges for files that never convert unless the vendor waives them.
3. Per seat subscription. A monthly fee per user, sometimes with a set number of demands included. Cheap for small teams with steady volume; expensive if you pay for seats that rarely use the tool.
4. Add-on or tier inside case management. Filevine sells its AI as modules, Neos puts AI in its top tier, and Litify's demands come through its platform. The demand cost hides inside a larger contract.
5. Service. You buy people plus software. EvenUp's Pre-Litigation as a Service, launched in May 2026, puts its own case managers on your files. You are paying for labor, sold as a subscription.

Published prices and third-party estimates

Two cautions on this table. First, a third-party estimate is often a competitor's estimate, so treat it as a range to test, not a quote. Second, the cheapest line is not always a demand: a medical summary is one input to a demand, not the letter.

What the sticker price leaves out

The number on a quote is rarely the number on the invoice. These are the costs buyers miss most often.

• Files that never convert. On per-case pricing, ask whether a case declined or dropped early is billed. On per-demand pricing, this cost is zero.
• Edit time. An attorney still reviews every demand. If a draft takes an hour to fix, that hour is part of the price. Measure it in a pilot.
• Turnaround. Some vendors charge more for faster drafts. Ask what the standard turnaround is in a busy week, not a quiet one.
• Records you don't have. A demand tool drafts from the records you give it. Retrieval is a separate service and a separate cost.
• Scans. If a tool cannot read scanned records, someone has to deal with them by hand. PlaintiffStack has this limit today.
• Contract terms. Annual commitments, license minimums and setup fees change the real cost per demand. Litify's pricing page, for example, sets a minimum license purchase plus setup fees.
• The case system. A demand-only tool sits next to a case management system you still pay for.
• Price changes. Prices and packaging in this market change often. A price-tracking site has logged several changes to CaseMark's summary pricing since 2025, for example. Ask for the price to be fixed for the contract term.

A worked example: 300 new PI cases a year

This is an illustration, not a quote. Assume a firm opens 300 PI cases a year and 60% of them (180) reach a demand. The vendor numbers come from the table above.

The comparison shows why a single "cost per demand" number misleads. A per-case price covers files that never reach a demand, but it may also replace the case system, the intake tool and the client portal. A per-demand price covers only the demand. Run your own numbers with the case management cost calculator, and read per-case vs per-seat pricing for when each model wins.

Questions to ask about price

1. Is the price per demand, per case or per seat, and what exactly counts as one?
2. What is included: chronology, bill summary, exhibits, revisions, rush turnaround?
3. Are files that never reach a demand billed?
4. Is there an annual commitment, a license minimum or a setup fee?
5. If people review drafts, is that included or extra?
6. What happens to the price at renewal?
7. Can we pilot on five to ten of our own files before we sign?
8. If we leave, what does it cost to export our data?

Where PlaintiffStack's price fits

PlaintiffStack publishes one number: $250 per case, every app included, no monthly fee and no long lock-in contract. That covers case management, intake, the client portal, e-signature, the settlement statement and the PI case tools (missing records report, treatment chronology, policy-limits demand). AI usage is billed separately: each tool shows an estimated cost before it runs, typically cents per run, and how usage is billed is part of your quote. Drafts cite the page each fact came from, and nothing is sent without a person.

It is likely to cost more than a demand-only tool if you already own a case system you like, and more than seat pricing if your firm opens many cases per user. It fits best when a California firm would otherwise pay for a case system, a demand tool and several smaller apps separately.
