"AI paralegal" now gets used for almost anything: a chatbot, a demand letter generator, an assistant built into a case system. That makes it hard to know what you are buying.
Here is a working definition. A paralegal's job is to keep cases moving across every place a case lives. So an AI paralegal is only worth the name if it works across those places too, not inside just one of them.
This guide covers what that should look like at a personal injury firm, system by system, and what to ask before you buy.
Where a PI case actually lives
Ask where the facts of one case sit, and most plaintiff firms give the same answer:
- The case system, such as Filevine, CASEpeer or Litify: status, deadlines, bills, liens, notes and tasks.
- Intake, such as Lead Docket or a CRM: the client's first account and everything said before the case was signed.
- Email: adjusters, providers, opposing counsel, and records arriving as attachments.
- Documents: medical records, police reports and photos in Dropbox, Google Drive or SharePoint.
- Billing and phones: payments, call logs and texts.
The AI built into a case system can be useful, but it sees only that system. The adjuster's email and the intake notes are outside its view. The questions that slow a firm down are usually the ones whose answers are split across two or three of these places.
What an AI paralegal should do in each system
In the case system
It should answer questions about one case or the whole caseload, in plain English:
- Which cases have a statute of limitations date in the next 90 days?
- Which clients have had no treatment update in a month?
- What is the status of every case assigned to one case manager?
It should also update the system when someone asks it to: add a note, change a status, create a task, enter a figure from a document.
In intake
It should read the intake record and brief the attorney before the consult: what happened, when, what injuries the caller described, and whether the caller is already a client. When a case signs, it should be able to open the client, contacts and matter in the case system from the signed engagement letter, so nobody types the same facts twice.
In email
It should find the one email that matters in a thread of hundreds, such as the IME notice or the policy limits letter. It should file correspondence and attachments into the right case. And it should draft replies for a person at the firm to review and send.
In documents
It should read the records where they already sit and cite the page behind every answer. Medical chronologies and demand drafts belong here, as two jobs among many, done in the firm's own format.
The questions only a cross system tool can answer
The real test is a question no single system can answer. For example:
- What is holding up this settlement? The answer might be a lien in the case system, a bill that never arrived, and an adjuster email nobody answered.
- Which providers did the client name at intake that we have no records from?
- Which hearing or deposition dates in email are missing from the calendar or the case?
A paralegal answers these by opening four tabs. An AI paralegal should answer them in one reply, and show where each piece came from.
It should run on its own, but only where you told it to
Answering questions is half the job. The other half is the work nobody asks for because it is always due. A good AI paralegal can be taught standing instructions in plain English, written as "when X, do Y":
- Each morning, list the cases with deadlines this week and what is still open on each.
- When records or bills arrive by email, file them in the client's case folder and note what came in.
- Every Monday, send the partner a status report on open cases.
The line that matters is what leaves the firm. An AI paralegal should draft the email to the client, the adjuster or the provider. A person at the firm reviews it and sends it.
It should learn how your firm works
Every firm has its own vocabulary, its own templates and its own way of doing things. When someone corrects the AI or explains how the firm does something, it should keep that and use it next time, rather than making the same correction necessary every week.
What it should never do
- Send anything outside the firm without a person approving it.
- See more than the person using it can see. It should act with each user's own permissions.
- Train AI on your clients' data.
- Make the judgment calls. Valuation, strategy and advice stay with the lawyers.
Questions to ask before you buy
- Does it work inside the systems we already use? Including the ones with no public API, and including intake and email, not only the case system.
- What has to move? The right answer is nothing. Your case system should stay the system of record.
- How long does connecting take? It should be minutes per system, not a migration project.
- Does it cite its sources? Every answer about a case should point to the record, email or field it came from.
- Can we teach it standing instructions? And can we see exactly what it did each time it ran?
- How is it priced? Per seat pricing charges again for every paralegal you add. Ask whether it is per seat or a flat fee for the firm.
- What happens to our data? Ask whether it trains AI, how each firm's data is kept separate, and whether every action is logged.
What this is really about
The value of an AI paralegal is not a clever answer. It is capacity: the same team keeping more cases moving, because the work that lives between systems gets done without someone tabbing through all of them.
CaseDelta built Delta to be that kind of AI paralegal. It works inside the case system, intake, email and documents a firm already uses, whichever ones those are, and a person at the firm approves what goes out.
