Personal injury case management software: 2026 buyer's guide and comparison

What PI case management has to do

General practice software tracks matters, time and bills. A PI firm needs more: it works on contingency, waits on records, tracks treatment and liens, and lives or dies on deadlines. Before you compare vendors, write down what your system has to do. Most PI firms need:

• Intake that captures the incident, insurance and treatment on the first call.
• Medical records and bills tracked per provider: requested, followed up, received, amount billed and paid.
• Treatment tracking, with gaps flagged.
• Liens from health plans, Medicare, Medi-Cal and providers, with reductions.
• Demands and offers, including time-limited demands and when they expire.
• Statute of limitations and claim deadlines, with the rule shown.
• A settlement statement that computes the fee, costs, liens and the client's net.
• Client updates that don't need a phone call.
• Trust accounting, in the system or in your accounting software.

Then rank the list. The features your team uses every day, like records tracking, tasks and deadlines, matter more than the ones it uses twice a year.

PlaintiffStack publishes this guide and is one of the platforms compared. Its limits: California rules only, no OCR for scans yet, SOC 2 Type II and ISO 27001 in progress, AI usage billed separately, no trust accounting, Outlook and Gmail not yet connected, and a young company. We checked the facts below on October 21, 2026.

The platforms compared

Notes on each

Filevine raised $400M in 2025 and has the deepest AI investment of the case systems: LOIS for case questions and agents, DemandsAI for demands, MedChron for chronologies. Reviewers praise its flexibility and note the setup it takes. Choose it if you have someone to configure and run it. See PlaintiffStack vs Filevine and Filevine alternatives.

Litify runs on Salesforce and began at Morgan & Morgan. Its demands now come from a partnership with Supio. It suits large firms that want Salesforce's reach and can staff it. See Filevine vs Litify and PlaintiffStack vs Litify.

SmartAdvocate is built for high-volume litigation, with a workers' comp module and a long integration list. SmartIntelligence, announced in August 2026, adds chronologies, demand generation and voice intake agents. See Filevine vs SmartAdvocate and Litify vs SmartAdvocate.

Neos is Assembly's cloud platform for firms leaving Needles or TrialWorks. Assembly says TrialWorks has no end-of-life date and that most firms moving from Needles are fully operational within a few weeks of go-live. See Needles vs Filevine and Needles and Neos alternatives.

8am CasePeer is PI-only and simpler to roll out, with settlement calculators and demand trackers. Its own AI was in early access as of a 2026 review, with production AI coming through integrations. See Filevine vs CasePeer.

CloudLex is PI-only, with Lexee AI for chronologies and demand drafting, and prices by quote. See PlaintiffStack vs CloudLex.

Clio is the general-practice leader. It fits firms with several practice areas and handles PI through add-ons, so volume PI firms often outgrow it. See Clio vs Filevine.

How AI fits into each

Case systems now handle AI in three ways, and the difference shows up in your bill and your workflow.

• Built in and priced as modules or tiers: Filevine, SmartAdvocate, Neos. One vendor, but the AI line on the quote can grow.
• Through a partner: Litify with Supio; CasePeer and Clio through integrations. You get a specialist's AI, and two vendors to manage.
• Built in, every app in one price: PlaintiffStack includes every app in the per-case price and bills AI usage separately, with an estimate shown before each run.

Whichever way, ask whether AI writes into the case on its own or proposes changes for a person to accept. In PlaintiffStack, agents propose facts, deadlines and tasks, and a person accepts them.

Implementation and switching

The license is rarely the hardest part. Moving years of cases, documents and deadlines is. Third-party reporting of G2 buyer data puts average implementation at about four months for Filevine and six for Litify. Litify's pricing page lists a minimum license purchase and setup fees. Assembly says Needles firms moving to Neos are usually running within a few weeks of go-live.

Ask for references from firms of your size and practice mix that switched in the last year, and ask them what took longest. A demo shows the best path through the product; a reference tells you about the rest.

Plan the move before you sign: what data comes over, who maps it, how you check deadlines during the cutover, and what it costs to leave. Our guide to switching case management software has a step-by-step plan.

How to choose, by firm size

• Solo to 5 attorneys, mostly PI: a PI-specific system with a short rollout (CasePeer, CloudLex) or, in California, PlaintiffStack. Avoid platforms that need a full-time admin.
• 5 to 25 attorneys, high volume: configurable platforms (Filevine, SmartAdvocate, Neos) or PlaintiffStack. Weigh AI pricing and migration time as heavily as features.
• 25+ attorneys or several offices: Filevine, Litify or SmartAdvocate, which have the integrations and admin tools large firms need.
• Several practice areas: Clio, or a PI platform with modules. PlaintiffStack covers PI, workers' comp and employment on California rules.

Questions to ask every vendor

1. What does year one cost, all in: licenses, AI, implementation, training, data migration?
2. Is there a license minimum or annual commitment? What happens at renewal?
3. Which AI features are included and which are extra?
4. Who migrates our data, what comes over, and how do we verify it?
5. Does it track records per provider, liens with reductions, and time-limited demands?
6. Does it do trust accounting, or connect to the system that does?
7. Does it sync with Outlook or Gmail?
8. How do we export everything if we leave, and what does that cost?

Where PlaintiffStack fits

PlaintiffStack is case management and AI on one record for California plaintiff firms. For PI, it ships California phases and pages, case tools for a missing records report, a treatment chronology and a policy-limits demand, morning checks for expiring offers and demands, untouched record requests and treatment gaps, lien tracking with reductions, and a settlement statement that computes the fee at 33.33%. It moves your cases, contacts and documents from your current system and checks the result with you. Live integrations today are Microsoft Word and Dropbox, with RingCentral in early access.

It is the wrong fit if you need trust accounting in the system, email sync today, OCR for scanned records, a SOC 2 report now, or rules outside California. See pricing, the personal injury page, integrations, and run your numbers with the case management cost calculator.
