By model
How each assistant handled Doulas questions.
Reading the 120 answers model by model shows how differently the three assistants treat the same doulas questions. On the most consequential behavior — whether to send the buyer to a professional at all — the rate ranged from 67.5% (ChatGPT) down to 55% (Gemini), a 13-point gap on an identical question set.
Across the 40 doulas answers it produced, ChatGPT recommended hiring a professional in 67.5% of them and suggested a DIY approach first 2.5% of the time. It named a specific provider in 0% of answers (about 0 distinct providers per answer) and included price or cost information 7.5% of the time. ChatGPT asked a clarifying question before answering in 50% of cases, warned about red flags or scams in 12.5%, and told the buyer to verify credentials in 32.5%, averaging 454 words per answer. On the remaining cues it told the buyer to check reviews in 20%, pointed to case studies or a portfolio in 10%, and framed the choice around local proximity in 30%; a selection-criteria checklist appeared in 57.5% of its answers and a recommendation to gather multiple quotes in 7.5%.
Across the 40 doulas answers it produced, Claude recommended hiring a professional in 60% of them and suggested a DIY approach first 0% of the time. It named a specific provider in 10% of answers (about 0.5 distinct providers per answer) and included price or cost information 10% of the time. Claude asked a clarifying question before answering in 35% of cases, warned about red flags or scams in 12.5%, and told the buyer to verify credentials in 10%, averaging 286 words per answer. On the remaining cues it told the buyer to check reviews in 7.5%, pointed to case studies or a portfolio in 2.5%, and framed the choice around local proximity in 20%; a selection-criteria checklist appeared in 45% of its answers and a recommendation to gather multiple quotes in 12.5%.
Across the 40 doulas answers it produced, Gemini recommended hiring a professional in 55% of them and suggested a DIY approach first 0% of the time. It named a specific provider in 10% of answers (about 0.4 distinct providers per answer) and included price or cost information 5% of the time. Gemini asked a clarifying question before answering in 0% of cases, warned about red flags or scams in 7.5%, and told the buyer to verify credentials in 5%, averaging 293 words per answer. On the remaining cues it told the buyer to check reviews in 5%, pointed to case studies or a portfolio in 2.5%, and framed the choice around local proximity in 10%; a selection-criteria checklist appeared in 22.5% of its answers and a recommendation to gather multiple quotes in 0%.
Taken together, ChatGPT is the assistant most likely to route a doulas buyer to a professional (67.5%) and Gemini the least (55%). ChatGPT produced the longest answers, at 454 words on average. Specific providers were named most often by Claude (10%) — even there, roughly one answer in 10 carried a name.
Where they disagree
The behaviors where the choice of model changes the answer.
The divergence index for this study is 20.6 points — the average distance between the most and least likely model across the coded behaviors. The gaps below are where which assistant a doulas buyer happens to ask matters most:
- Asks a clarifying question: from 0% (Gemini) to 50% (ChatGPT) — a 50-point spread.
- Gives selection criteria: from 22.5% (Gemini) to 57.5% (ChatGPT) — a 35-point spread.
- Tells the buyer to verify credentials: from 5% (Gemini) to 32.5% (ChatGPT) — a 28-point spread.
- Mentions local proximity: from 10% (Gemini) to 30% (ChatGPT) — a 20-point spread.
- Tells the buyer to check reviews: from 5% (Gemini) to 20% (ChatGPT) — a 15-point spread.
The widest single gap — asks a clarifying question, 50 points — means a doulas buyer can receive materially different guidance on the same question depending only on which assistant they happen to open, so any visibility strategy built on a single model's behavior describes only part of the doulas market.
Where they agree
The points of near-consensus in Doulas.
On other behaviors the three models move almost in lockstep — the points of near-consensus for doulas, where all three landed within a few points of each other:
- Suggests a DIY approach first: 0%–2.5% across all three (a 3-point spread).
- Gives price or cost information: 5%–10% across all three (a 5-point spread).
- Warns about red flags or scams: 7.5%–12.5% across all three (a 5-point spread).
- Mentions case studies or portfolio: 2.5%–10% across all three (a 8-point spread).
Measured question by question, the three assistants coded a response the same way most consistently on "suggests a DIY approach first" (identical coding in 97.5% of questions) and least consistently on "gives selection criteria" (22.5%).

Trust signals
How well the models protect the doulas buyer.
Beyond whether to hire, the rubric codes how carefully each assistant protects the doulas buyer once a decision is made. Telling the buyer to check reviews or ratings appeared in 10.8% of answers on average. Verifying credentials or certifications appeared in 15.8%. Warning about red flags or scams appeared in 10.8%.
On structuring the decision, a selection-criteria checklist showed up in 41.7% of answers on average and a recommendation to gather multiple quotes in 6.7%. The single least-reproduced protective signal for doulas is "recommends multiple quotes" at 6.7% on average — the clearest opening for content that supplies it, since the models are not yet reliably surfacing that guidance on their own.
Referral behavior
Do AI models name Doulas providers?
For service providers the decisive question is whether these systems name anyone at all. Across 120 doulas answers, a specific provider was named in 6.7% of responses on average — roughly 0.3 distinct providers per answer. In practice the assistants behave far more as an explanatory layer than as a referral engine for doulas: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.
The question set
What these 40 Doulas questions cover.
The 40 questions behind every percentage on this page were drawn from real doulas (healthcare services; buyer hiring decisions for this specific service) buyer journeys. Each was put to all 3 models once, with identical wording, so the rates above describe how the assistants handled this exact doulas question set — not a general prior or a hand-picked subset. The full list is shown earlier on this page; the coded percentages are what those specific questions produced.
How to read this
A note on the numbers.
A percentage here is the share of a model's 40 answers in which the behavior appeared at least once — not a confidence score. Because each model answered every question exactly once on 2026-07-06, the figures describe this specific doulas question set and snapshot rather than a general prior. The full protocol and coding rubric are documented in the study methodology.
Methodology
A controlled snapshot, documented end to end.
40 standardized buyer questions per industry, one response per model per question (ChatGPT (gpt-5-mini), Claude (claude-sonnet-5), Gemini (gemini-3-flash-preview)), collected 2026-07-06, coded against a fixed 12-behavior rubric with human QA. AI outputs vary with model version, location and time — figures describe this sample and window, and are refreshed each edition. Read the full methodology →
