AI search and law firms: the numbers that matter in 2026
The most useful independent figures on how clients use AI to find lawyers, which sources AI engines trust, and how far plaintiff firms have really adopted AI. Each figure links to its original source, with notes on where studies disagree.
Key takeaways
Five things every managing partner should know.
- Clients now ask AI for recommendations. 45% of US adults use AI for local business recommendations, up from 6% a year earlier (BrightLocal).
- AI engines rarely agree. Only 3.8% of cited sources were cited by all four major engines, and 72 to 73% were unique to one engine (Writesonic).
- Directories decide many answers. A legal directory was the first source in 77.8% of Perplexity answers, and 34.2% of firms named had no page of their own cited (InterCore).
- AI Overviews appear on fewer legal searches than claimed. Ahrefs measured Law and Government at 23.1% against a 20.5% baseline (Ahrefs), well below the 78% figure circulating in a 2026 press release.
- Plaintiff firms are curious, not committed. 78% have engaged with AI, but only 30% use it regularly (Supio).
Demand
How clients use AI to find a lawyer
| Finding | Figure | Source |
|---|---|---|
| US adults using AI for local business recommendations | 45% (up from 6%) | BrightLocal Local Consumer Review Survey |
| Consumers who asked AI a legal question and were told to contact a lawyer | 28% | Clio |
Engines
Every AI engine shows a different shortlist
Optimizing for one assistant does not cover the others. These studies measured how little the engines overlap.
| Finding | Figure | Source |
|---|---|---|
| Cited sources shared by all four major engines | 3.8% | Writesonic citation overlap study |
| Cited sources unique to a single engine | 72 to 73% | Writesonic |
| Sources shared by ChatGPT and Perplexity | About 13% | Writesonic |
| Overlap in named firms, ChatGPT vs Perplexity, same city and practice (38,173 answers, 25 practice areas, 15 cities) | About 6% | Forward Push study via National Law Review |
| Gemini naming a firm in personal injury answers | 69% in one study, about 12% in another | Citorian, Forward Push |
Sources
Directories and third-party sites carry most of the weight
| Finding | Figure | Source |
|---|---|---|
| Perplexity answers where a directory was the first source (540 queries, 6 practice areas, 30 metros) | 77.8% | InterCore |
| Firms named with no page of their own cited | 34.2% | InterCore |
| Share of citations from Super Lawyers and Justia combined | 53% | Citorian |
| Lawyers.com share of citations | 5.72% in one study, 0% in another | InterCore, Citorian |
| Reddit share of citations | 8% in one study, 2.04% in another | InterCore, Citorian |
AI Overviews and clicks
| Finding | Figure | Source |
|---|---|---|
| Share of all keywords showing an AI Overview, November 2025 | Under 16% | Semrush data via Search Engine Land |
| Law and Government queries showing an AI Overview | 23.1% (baseline 20.5%) | Ahrefs |
| Reduction in clicks when an AI Overview appears | 58% | Ahrefs |
A June 2026 press release claimed 78% of legal queries trigger an AI Overview and attributed it to Semrush. The Semrush study it cites does not support that figure.
Adoption
How far plaintiff firms have really adopted AI
| Finding | Figure | Source |
|---|---|---|
| Plaintiff attorneys and leaders who have engaged with AI (207 surveyed) | 78% | Supio 2026 |
| Using AI regularly | 30% | Supio |
| Experimenting on isolated tasks / still evaluating / no plans | 23% / 25% / 22% | Supio |
| Will not use AI content they cannot verify | 99% | Supio |
| Rank source-level traceability as a priority | 71% | Supio |
| Case volume regularly exceeds team capacity | 42% | Supio |
| Need a week or more to send a demand letter | 57% | Supio |

What it means
My read, after 14 years selling into law firms
The numbers point in one direction. Clients are already asking AI who to hire, but the engines disagree with each other, and they lean heavily on directories and third-party profiles rather than on firm websites. A firm can rank well on Google and still be missing from the shortlist an assistant gives a prospective client.
That changes where the work starts. Before writing more content, a firm needs to know which engines name it, which sources those engines trust in its market, and where its own profiles are incomplete or inconsistent. Directory profiles, reviews and consistent firm information now matter as much as the website itself.
On adoption, the gap between trying AI and relying on it is about trust. Firms move from experimenting to regular use when they can verify the output against their own files. Vendors selling to those firms should lead with traceability, not features.
FAQ
Quick answers
How many people use AI to find a local business or lawyer?
BrightLocal found that 45% of US adults now use AI for local business recommendations, up from 6% a year earlier.
Do ChatGPT, Gemini and Perplexity recommend the same law firms?
Rarely. One study of 38,173 answers found ChatGPT and Perplexity named overlapping firms only about 6% of the time for the same city and practice area, and only 3.8% of cited sources were shared by all four major engines.
What sources do AI assistants cite for lawyer recommendations?
Mostly legal directories and third-party sites. In one study a directory was the first source in 77.8% of Perplexity answers, and Super Lawyers and Justia together supplied 53% of citations in another.
How often do Google AI Overviews appear on legal searches?
Ahrefs measured Law and Government queries at 23.1%, against a 20.5% baseline across all queries. Claims that 78% of legal queries trigger an AI Overview are not supported by the Semrush study they cite.
How many plaintiff firms use AI regularly?
In Supio’s 2026 survey of 207 plaintiff attorneys and firm leaders, 78% had engaged with AI but only 30% used it regularly.
Figures are third-party research, compiled and checked against the original sources by Sagar Pratap Singh. Studies use different methods and dates, which is why some figures disagree. To cite this page: “AI search and law firms: the numbers that matter in 2026”, WhoBringsTheBusiness, October 2026.
