How will people find lawyers in the age of AI?

I’m Dan Toombs, a lawyer and founder of FirmRanker. I’m studying how AI systems discover, evaluate and recommend law firms — and what that means for how people find and choose lawyers.

01 The change

The shift

From search, to answer, to recommendation.

For most of the internet era, finding a lawyer online meant searching. A prospective client typed “personal injury lawyer Sydney” and received pages of choices.

AI changes the interaction. A person can describe the problem itself and ask which firms they should consider.

Traditional search presents choices. AI can increasingly narrow those choices — and sometimes make a recommendation.

That introduces a new layer between the prospective client and the law firm: the AI recommendation layer.

01 · Search

Find possible firms

“personal injury lawyer Sydney”

02 · Answer

Narrow the field

“Who are the leading firms in Sydney?”

03 · Recommendation

Make a choice

“I have this problem. Which firms should I consider?”

The further along this line a client goes, the fewer firms they see — and the more the AI’s view of your firm matters.

The commercial question

AI doesn’t have to replace Google to matter.

Legal services are unusual. A single instruction can represent substantial fees. AI only needs to influence a meaningful proportion of legal discovery for its recommendations to matter.

The old question

Does your firm rank?

The new question

Does AI know who your firm is — and does it consider you when someone asks for a lawyer like you?

For law firm leaders

What should a law firm do about this now?

The answer isn’t to panic. It also isn’t to wait until every uncertainty disappears.

The sensible starting point is to understand whether your firm is appearing in the AI systems your prospective clients may increasingly use — and what those systems appear to understand about you.

02 The research problem

The new object of study

What happens between the question and the recommendation?

We cannot see every internal weighting. We can measure the information environment and the outputs.

Observable — recorded directlyInferred — studied from the outside

A The question

01

Client question

A person describes a legal problem in their own words.

Observable
02

Intent

The system interprets what kind of help they need, and where.

Inferred

B The information environment

03

Retrieval

It may search the web or rely on what it already knows.

Partly observable
04

Sources

What it reads — and what it chooses to cite.

Observable
05

Firm entities

Names, lawyers, places and practices resolved into firms.

C The answer

06

Consideration set

A short list of firms worth considering.

Observable
07

Recommendation

Sometimes, an explicit choice.

Observable

We should not pretend we know how every model weights every signal. We don’t.

That is exactly why the work starts with measurement before optimisation — recording what goes in and what comes out, repeatedly.

How we measure it→

The work

I’m studying how AI chooses lawyers.

01

Recommendations

Which firms are actually surfaced and recommended?

02

Stability

Does the same question repeatedly produce the same firms?

03

Cross-platform differences

Do ChatGPT, Gemini, Claude and Perplexity agree?

04

Prompt sensitivity

Does wording or client intent change the consideration set?

05

Sources & authority

What does AI search, cite and use around law-firm answers?

06

Change over time

How stable is visibility as models and the web change?

03 The evidence

The research engine

Don’t guess. Measure.

FirmRanker treats AI visibility as something to be observed repeatedly, not as a permanent search ranking.

04 The perspective
Dan Toombs

The perspective

I’ve spent more than 20 years inside this problem.

AI is new. The underlying problem isn’t.

I’ve worked across law, legal publishing, law reform, technology, legal marketing and law-firm growth. Each shift changed the tactics. The deeper question stayed remarkably consistent.

“How does someone who needs legal help decide which lawyer to trust?”
