Personal injury firms can now get AI demand letters and medical chronologies drafted inside the case file
Assembly Software's Neos Demands Plus gives personal injury firms AI demand letters and medical chronologies drafted from records in the case file.
Personal injury firms on Neos can now get AI demand letters and medical chronologies drafted from the records already in a case. Assembly Software made Neos Demands Plus generally available on November 10, 2026, with an attorney approving each demand before it goes out.
Key points
- Assembly Software says Neos Demands Plus builds medical chronologies and drafts settlement demand letters from the records already stored in a Neos case file.
- Citations in both drafts open the original records in Neos, and an attorney approves each demand before it leaves the system, according to the company.
- Assembly says beta reports and early estimates put drafting plus attorney review at about 30 minutes per demand, against three to 10-plus hours by hand.
- The feature is available now to Neos firms on the NeosAI Platinum tier, priced by caseload, and Assembly says case data is not used to train AI models.
How are AI demand letters drafted in Neos?
Demands Plus reads the medical records and case file a firm already keeps in Neos and drafts the demand from them, modelled on the firm's own past letters, Assembly says in its announcement. It covers motor vehicle, premises liability and workers' compensation matters, among other high-volume plaintiff work.
The chronology is the groundwork. According to Assembly, the tool refreshes it whenever new records come in, picks out the injuries and treatment that matter for the claim, and points out gaps in treatment and records that may be missing, such as the report for an MRI that was ordered. The demand is then written from that treatment history and the rest of the client's file.
Two details are aimed at how plaintiff firms run their books and their review. Citations in the chronology and the demand link back to the source records, so the reviewing attorney can check a fact without leaving the case. And once a demand is final, Neos posts what it cost to the case as a recoverable expense instead of firm overhead, the company says.
How much time does a demand letter take to prepare by hand?
Several hours for the demand, and far longer for the chronology behind it, according to one of the beta firms. At Pfeifer, Morgan & Stesiak, a Demands Plus beta firm, staff rebuilt the chronology whenever new records arrived.
| Task | Time | Source |
|---|---|---|
| Demand letter, by hand | three to four hours | Pfeifer, Morgan & Stesiak |
| Medical chronology, by hand | 10 to 20 hours | Pfeifer, Morgan & Stesiak |
| Demand letter, by hand | three to 10-plus hours | Assembly's estimate |
| Demand letter drafted and reviewed with Demands Plus | about 30 minutes | Assembly's beta reports and early estimates |
"We evaluated other AI tools, but they all operated outside Neos and would have added another system for our team to manage. Demands Plus brings AI efficiencies into the platform where our work already happens."
— Maggie Cuson, operations manager and Neos administrator, Pfeifer, Morgan & Stesiak
Cuson says the firm believes the tool could support as much as 10% growth by giving staff more capacity for cases and clients.
Paul Hernandez, a partner at Kalfus & Nachman, P.C., says his firm has 20 lawyers and 12 pre-litigation paralegals, and that he wanted the same standard on every demand the office sends.
"With Demands Plus, our team can move through medical records faster and produce chronologies and demands that are consistent, high quality, and authentic to the way our firm communicates, all inside the case management platform we already use."
— Paul Hernandez, Partner, Kalfus & Nachman, P.C.
How fast are lawyers adopting AI?
Quickly. In the State Bar of Texas's 2026 AI in the Practice of Law Survey, published on June 18, 2026, the share of Texas attorneys using AI rose from 30% in 2024 to 62%; legal research was the most common use, at 53%, and ethical concerns were the reason most often given by those who do not use it, at 59% (State Bar of Texas).
Assembly cites the same survey for personal injury practice, where it says AI use among respondents climbed from 35% in 2024 to 69% in 2026, and it names drafting, document management and summarization among the survey's most common uses.
What do Texas ethics rules say about AI-drafted legal work?
The lawyer stays responsible for it. In Opinion 705, issued in February 2025, the Texas Professional Ethics Committee said a lawyer should always verify the accuracy of what a generative AI tool returns, should be reasonably satisfied that a program will not reveal confidential information or else get the client's consent before entering any, and may not bill hourly for time the tool saved; for per-use AI costs, a lawyer generally may recover no more than the expense actually incurred (Texas Professional Ethics Committee, Opinion 705).
What Demands Plus means for personal injury practices
Our analysis: Opinion 705 sets out the questions a plaintiff firm has to answer before AI touches a client's medical file, and several features Assembly describes bear directly on them. Citations that open the source record give the reviewing attorney a way to verify each fact against the chart, and the requirement that an attorney approve every demand keeps that check in the workflow. Assembly's statement that case data does not train its models speaks to confidentiality. Posting each demand's cost to its case is the kind of per-use cost the opinion addresses, tracked matter by matter. With ethical concerns the top reason Texas lawyers give for not using AI (State Bar of Texas), those features are likely to be what a cautious firm looks at first.
