AI for small law firms: what is worth buying, in order of payback

The pitch arrives most weeks. A research tool that reads everything. A drafting assistant that writes the brief. A platform that does intake, billing and marketing in one login. Each is described as what small firms have been waiting for.

Some of it is useful. Almost none of it is useful first. The question for a firm of one to five lawyers is not which AI is best; it is which problem, solved, returns the most for the least risk. Ranked that way, the order is fairly stable.

First: the calls you are losing

A small firm’s most expensive problem is invisible. Someone searched, found the firm, read the reviews, called, reached voicemail and called the next name. Nothing recorded it. No tool that helps with the work you already have can touch this, because the matter never arrived.

The two automations that fix it are cheap and low-risk. A missed-call text-back sends the caller a text within a minute. An after-hours receptionist answers, takes details, asks the questions you approved and books a consult that a person confirms in the morning. Neither gives advice. Neither accepts a matter. Both are described in detail in AI intake for law firms, and the offer page sets out how a firm gets them without renting a seat on someone’s platform.

Everything below assumes this is done. A firm that buys a drafting tool while its phone rings out at 6pm has automated the wrong end.

Second: the work you already do

Once the matters are arriving, the next payback is in the hours spent on them. Here the useful tools are the general assistants most lawyers already have access to, used with a safe setup, and the useful habit is one check.

Drafting from your own precedents. A first draft assembled from the firm’s own prior work, in the firm’s own voice, is worth an hour a document on the right matters. The method is in a first draft from your own precedents. The condition is that the lawyer who signs it reads all of it.

Checking citations before you rely on them. Every assistant will, sooner or later, produce a case that does not exist. The check takes minutes and is the difference between a useful tool and a sanctions hearing. The check is here.

Summaries and extraction. The same fields pulled out of every document in a set, or a long record reduced to what matters. Useful once you have a way to test the output against a sample you have read yourself.

The ABA’s Formal Opinion 512 is the reference for what the existing duties require here: competence with the tool, confidentiality of what goes into it, candour with clients and courts about its use where it matters, and fees that reflect time actually spent. None of it is new law. All of it applies.

Third: research

Research tools built for lawyers are improving quickly and some are now affordable for a solo practice; the ABA has written up at least one aimed squarely at solo and small firms. They sit third not because they are weak but because a small firm’s research load is usually smaller than its intake or drafting load, and because the same citation check applies whatever tool produced the answer.

What to skip, for now

A platform you cannot leave. If the intake, the documents and the client records all live behind one vendor’s login, the firm has traded a problem for a dependency. Ask what you keep when you stop paying. If the answer is an export you have to request, keep looking.

Anything sold on accuracy without a test. “Ninety-five per cent accurate” means nothing until you know on what. Ask for the evaluation set, or make your own: twenty documents you have read, run through the tool, scored by hand. The case studies on this site show what that looks like, including where it was not done and what it cost.

Chatbots that answer legal questions on the website. A prospective client who asks “do I have a case” and gets an answer from a widget has received something that looks like advice from your firm. A widget that takes their details and books a time is intake. Know which one you are buying.

The governance a small firm actually needs

Not a committee. One page, kept current, that says:

• which tools the firm uses and for what;
• what never goes into a general-purpose assistant (client identifiers, privileged material, anything under a protective order);
• who checks output before it is relied on, and how;
• what clients are told, and when;
• how the firm handles a tool getting something wrong.

The D.C. Bar’s guide for small firms covers similar ground from the ethics side. The point is that the page exists and is read, not that it is long.

The order, on one line

Answer the phone. Then draft from what you already have and check every citation. Then research. Skip anything you cannot leave or cannot test. Write the page.

A firm that wants the order applied to its own practice, with the actual workflows mapped before any tool is chosen, is what the readiness assessment is for. A firm whose phone is the problem should start with the offer.
