Summary
To see which purchase sources and electronics retailers major generative AIs recommend for buying a dishwasher, Stellagent Inc. asked five AI services — ChatGPT, Gemini, Claude, Perplexity, and Microsoft Copilot — across six purchase scenarios, five times each, for 150 questions in total. The survey had two stages: first we checked recommendation trends across purchase-source categories including electronics retailers, Amazon, Rakuten Ichiba, Kakaku.com, and manufacturer official; then we limited the question to electronics retailers and, under a nationwide, general-context condition that uses neither the user's location nor prior context, checked which retailer names the AI ranked highly.
| Metric | Result |
|---|---|
| Target AIs | 5 services (ChatGPT, Gemini, Claude, Perplexity, Copilot) |
| Number of runs | 5 AIs × 6 scenarios × 5 runs · 150 answers total |
| Primary tally (within-retailer comparison) | 75 answers (S4R–S6R) |
| Answers with a specific retailer name | 63 answers |
| Top on ranking points in the primary tally | K's Denki (184 points) |
| Most first-place picks in the primary tally | Yodobashi Camera (22 times) |
| Mentions of branch faucet | 61 of 63 answers (96.8%) |
| Mentions of rental conditions | 33 of 63 answers (52.4%) |
In the within-retailer comparison (S4R–S6R, 75 answers), among the 63 answers from which a specific retailer name could be extracted, K's Denki led with 184 ranking points. Bic Camera followed at 174 and Yodobashi Camera at 166 — the top three within a narrow margin. Yodobashi Camera had the most first-place picks at 22. The full text of the six prompts used in this survey is provided in the appendix at the end of this article.
The chart above may be reproduced as-is in media coverage, articles, and other materials, provided that you credit "Stellagent Inc." as the source and include a link to this page.
Meanwhile, in-store consultation, installation work, warranty, and branch faucet were mentioned in over 90% of answers, while mentions of rental conditions came to 33 answers (52.4%), water supply/drainage to 30 answers (47.6%), and capacity/family size to 9 answers (14.3%).
Background
While a dishwasher's base price is easy to compare online, confirming installation conditions is important in an actual purchase. For countertop models, placement, branch faucet, water supply/drainage, and rental conditions tend to become issues; for built-in models, construction work, estimates, and replacing an existing unit come into play.
When generative AI becomes an entry point for purchase consultation, electronics retailers need to organize not only price and assortment but also their strengths — installation consultation, construction work, warranty, and in-store consultation — in a form AI can understand. In this survey, we collected major generative AIs' answers to dishwasher purchase consultations under identical conditions and examined the recommendation of purchase sources and how confirmation items were guided.
Scenarios Used
We designed six scenarios in two stages: the purchase-source category comparison (S1–S3) and the within-retailer comparison (S4R–S6R). S4R–S6R were entered as nationwide generalizations that use neither the user's location nor nearby-store information, and were treated as the authoritative data for the published ranking. The full text of the prompts actually entered for each scenario is provided in the appendix at the end of this article.
| ID | Scenario | Condition |
|---|---|---|
| S1 | General dishwasher purchase consultation | No purchase-source category specified; observe which sources the AI naturally raises |
| S2 | Purchase consultation with installation/branch-faucet concerns | State concerns about kitchen placement, branch faucet, rental use, countertop vs. built-in, and installation work |
| S3 | Price-focused, comparing online purchases | Explicitly compare Amazon, Rakuten, Kakaku.com, electronics retailers, and manufacturer official |
| S4R | General comparison within electronics retailers (nationwide) | Without using location etc., compare electronics retailers as a nationwide generalization |
| S5R | Installation/branch-faucet-focused comparison within retailers (nationwide) | Observe retailer recommendations that account for countertop/built-in, branch faucet, installation space, rental conditions, construction/estimate, and warranty |
| S6R | Balancing price and peace of mind within retailers (nationwide) | Observe retailer recommendations that balance low price with the peace of mind of installation, branch faucet, and warranty |
K's Denki Leads on Ranking Points in the Within-Retailer Comparison
As the authoritative data for the published ranking, we used the 75 answers from S4R–S6R as the population and tallied the 63 answers from which a specific retailer name could be extracted. As a result, K's Denki led with 184 points. All of the top five appeared in all five AIs and all three scenarios.
| Rank | Normalized name | Ranking points | Recommendations | First-place picks | AIs spanned | Scenarios spanned |
|---|---|---|---|---|---|---|
| 1 | K's Denki | 184 | 57 | 18 | 5 | 3 |
| 2 | Bic Camera | 174 | 53 | 5 | 5 | 3 |
| 3 | Yodobashi Camera | 166 | 45 | 22 | 5 | 3 |
| 4 | Yamada Denki | 147 | 50 | 7 | 5 | 3 |
| 5 | EDION | 125 | 52 | 5 | 5 | 3 |
| 6 | Kojima | 27 | 8 | 2 | 3 | 3 |
| 7 | Joshin | 23 | 10 | 0 | 3 | 3 |
| 8 | Nojima | 11 | 7 | 0 | 2 | 3 |
Ranking points were tallied by the recommendation rank in the answer: 5 points for first place, 4 for second, 3 for third, 2 for fourth, and 1 for fifth. In a tie, the design compares in the order of recommendation count, first-place picks, number of AI services spanned, and number of scenarios spanned. K's Denki finished first on ranking points with 18 first-place picks and 57 recommendations. Yodobashi Camera had the most first-place picks at 22, but with 45 recommendations it placed third on ranking points.
That said, the top three (K's Denki 184, Bic Camera 174, Yodobashi Camera 166) are all within a narrow margin, and the order changes depending on the metric used. It is more accurate to read this result as the top group being tightly bunched on a ranking-point basis, with K's Denki edging slightly ahead. The ranking targets recommendation rows that could be normalized to a specific store name; rows that stay at a general category name such as "electronics retailer" or "online retailer" are not included in the store-level ranking. Such cases are few and do not affect the order of the top eight even if included.
In General Consultations, Electronics Retailers and EC Marketplaces Are Often Listed Together
In the 75 answers of S1–S3, which specify no purchase-source category (73 of which yielded a specific purchase source), electronics retailers had 114 recommendation rows, EC marketplaces 101, manufacturer official 45, price-comparison sites 29, housing-equipment dealers 8, and home centers 5. Because multiple purchase sources appear in a single answer, the number of recommendation rows does not match the number of answers.
| Purchase-source category | Recommendation rows |
|---|---|
| Electronics retailers | 114 |
| EC marketplace | 101 |
| Manufacturer official | 45 |
| Price-comparison site | 29 |
| Housing-equipment dealer | 8 |
| Home center | 5 |
In dishwasher purchase consultations, AI answers tended to raise electronics retailers while also listing Amazon, Rakuten Ichiba, Kakaku.com, and manufacturer official as comparison targets. In price-focused consultations, EC marketplaces and price-comparison sites rose to the top, whereas in consultations that included concerns about installation or branch faucet, electronics retailers rose to the top on the grounds of in-store consultation and arranging construction work.
Installation, Branch Faucet, and Warranty Are Guided in Most Answers; Rental Conditions and Drainage Remain Gaps
In the 63 within-retailer answers with a specific retailer name, in-store consultation was mentioned in 63 answers (100.0%), installation work and warranty in 62 answers each (98.4%), and branch faucet in 61 answers (96.8%). As dishwasher-specific confirmation items, AI answers guided construction work and branch faucet at high rates.
| Confirmation item | Answers with a mention | Mention rate |
|---|---|---|
| In-store consultation | 63 / 63 | 100.0% |
| Installation work | 62 / 63 | 98.4% |
| Warranty | 62 / 63 | 98.4% |
| Branch faucet | 61 / 63 | 96.8% |
| Countertop / built-in | 57 / 63 | 90.5% |
| Installation space / dimensions | 53 / 63 | 84.1% |
| Estimate / on-site inspection | 50 / 63 | 79.4% |
| Rental conditions | 33 / 63 | 52.4% |
| Water supply / drainage | 30 / 63 | 47.6% |
| Disposal / collection | 17 / 63 | 27.0% |
| Drying function | 15 / 63 | 23.8% |
| Capacity / family size | 9 / 63 | 14.3% |
The chart above may be reproduced as-is in media coverage, articles, and other materials, provided that you credit "Stellagent Inc." as the source and include a link to this page.
That said, installation work, warranty, and branch faucet are also items explicitly touched on in the S5R and S6R prompts, so their mention rates include the influence of the prompt wording. When gauging the degree of spontaneous mention, please read this alongside items named in none of the prompts, and the fact that rental conditions — named only in S5R — remained at 52.4%. Mentions of rental conditions came to 33 answers (52.4%), water supply/drainage to 30 answers (47.6%), disposal/collection to 17 answers (27.0%), and capacity/family size to 9 answers (14.3%). While AI answers pick up the representative installation risks of a dishwasher purchase, finer confirmation items tailored to the living environment varied by answer.
Implications for Businesses
Purchase-Support Information Read by AI Is Not Just About Price
Even for AI, a dishwasher is treated not as a "buy on price alone" product but as one where the purchase source is chosen with installation, construction work, branch faucet, and warranty in mind. Electronics retailers appeared in AI answers alongside EC marketplaces and price-comparison sites, and being able to clearly guide in-store consultation, installation consultation, construction work, and warranty was a reason for recommendation. It is important to organize this purchase-support information on product pages, FAQs, and in-store consultation flows in a form AI can easily read.
Confirmation Items Tailored to the Living Environment Are Easily Missed in AI Answers
Confirmation items tailored to the living environment — rental conditions, water supply/drainage, capacity/family size, and disposal/collection — remained gaps that varied by answer. For electronics retailers to be chosen in AI-mediated purchase consultations, it is important to organize the conditions to confirm before buying a dishwasher — on product pages, FAQs, in-store consultation flows, and installation-work pages — in a form AI can easily read.
Nationwide Generalizations and Area-Specific Recommendations Must Be Designed Separately
In S4R–S6R, we asked as a nationwide generalization that does not use location or nearby-store information. In actual purchasing, nearby stores, delivery-coverage areas, installation-coverage areas, stock, and campaigns shape the outcome. On official sites, it is important to organize separately the strengths conveyed as a nationwide generalization and the information that should be conveyed by area and by store.
Survey Method (Details for Reproduction)
This is an AI-answer experiment. So readers can reproduce and verify it under the same conditions, we disclose the operator, subjects, selection criteria, target AIs and conditions, context-influence control, recorded items, extraction/normalization/aggregation methods, deviations/reruns/exclusions, external sources, and the handling of ethics and privacy.
The objective was to check which purchase sources and electronics retailers major generative AIs recommend for a dishwasher purchase consultation, and whether they guide users all the way to countertop/built-in, branch faucet, installation space, rental conditions, construction/estimate, warranty, and in-store consultation flows. The conducting body is Stellagent Inc., and the operator is Codex. The subjects are recommendation answers by major generative AIs about where to buy a dishwasher, and the survey date is August 4, 2026. The selection criteria for the target AIs were major general-purpose generative AIs and search/answer-engine-type services that general users in Japan can use via a web UI and that are commonly used for product purchase consultations. The number of answers collected is 5 AIs × 6 scenarios × 5 runs each, 150 answers in total.
Target AIs and Conditions
For each answer, we saved, per answer, the collection timestamp, AI service, model name or display name, contract plan, web-search setting, scenario ID, run number, input prompt, retrieved URL, and full answer text. Because the internal model version (display name) of each answer could not be identified in each service's web UI, this survey does not fix the model generation. As for contract plan, only ChatGPT was collected on a paid plan (Plus); the other four services were collected while logged in. Web-search usage differed by service, mixing automatic use, search mode, and no explicit search operation. Therefore, when comparing recommendation trends across services, please treat them as reference values that include these differences in conditions. The conditions for each target AI are as follows.
| AI service | Model name / display name | Contract plan | Web-search setting |
|---|---|---|---|
| ChatGPT | ChatGPT Web (model display unconfirmed) | ChatGPT Plus (user's contracted environment) | No explicit search operation (answers may include web-sourced citation displays) |
| Gemini | Gemini (display unconfirmed) | Logged in | Automatic web search used |
| Claude | Claude (display unconfirmed) | Logged in | Web-search setting unspecified |
| Perplexity | Perplexity (display unconfirmed) | Logged in | Search mode |
| Copilot | Copilot (display unconfirmed) | Logged in | Automatic web search used |
Context-Influence Control
Each answer was collected in a new chat, Temporary mode, a temporary chat, an incognito chat, or a chat that can suppress contextual influence. Within the prompt, we also specified not to reference past conversation or memory. In S4R–S6R, we specified not to use current location, address, IP address, nearby stores, nearest stores, local store conditions, account information, search history, past conversation, or memory. This let us observe how retailer names appear as a nationwide generalization for all of Japan, rather than specific-area store conditions.
Extraction, Normalization, and Aggregation
We extracted the purchase sources that appeared in each answer, using their order of appearance in the answer as the recommendation rank. Even when the AI did not state an explicit ranking, we treated the order of appearance in the body text as the recommendation rank. When multiple stores were listed together, we still recorded them in order of appearance at extraction time. We did not treat search-result lists, citation/source labels, or source titles containing a store name as a recommendation rank; we prioritized explicit rankings, ranking tables, and headings within the answer body for extraction.
We saved the original notation as-is, then converted it to a normalized name for aggregation. For example, "Yodobashi" and "Yodobashi.com" were treated as Yodobashi Camera, and "Yamada Denki (Yamada Electric)" and "Yamada Web.com" as Yamada Denki. Amazon, Rakuten Ichiba, Yahoo! Shopping, online retailers, Kakaku.com, manufacturer official, housing-equipment dealers, and home centers were also classified as purchase-source categories.
Ranking points were tallied as 5 points for first place, 4 for second, 3 for third, 2 for fourth, and 1 for fifth. For the within-retailer ranking, we used the 75 answers of S4R–S6R as the population and listed, in descending order of ranking points, the 63 answers from which a specific retailer name could be extracted. In a tie, we compare in the order of recommendation count, first-place picks, number of AI services spanned, and number of scenarios spanned. Mentions of confirmation items were judged on a per-answer basis and tallied against the 63 answers with a specific retailer name as the denominator. Extraction and normalization were script-assisted; after a pre-publication review correction, we cross-checked against representative logs and re-tallied the top brands and main confirmation items from the primary data.
Deviations, Reruns, and Exclusions
Answers in which no purchase-source or retailer name appeared were also saved as logs, managed separately as "no specific name" in the ranking tally, and excluded. Of the 150 answers this time, 14 answers were "no specific name," and of the 75 within-retailer answers, 12 were "no specific name." Copilot's S3-r5 timed out on the first collection, so we re-ran it with the same AI, same scenario, and same run number and analyzed the re-run answer. Some Claude answers consisted only of a search-result list, from which no purchase-source recommendation could be extracted as answer body, so they were excluded from the ranking and recommendation rows as "no specific name." In response to a pre-publication review, we corrected the extraction policy so that citation/source labels and store-name labels are not miscounted as recommendation ranks, and regenerated the tally.
External Sources and Confirmation Method
External sources were confirmed on August 4, 2026. External sources were used not to judge the correctness of AI answers, but to confirm, when interpreting results, that official flows for purchase-support items exist. This survey does not judge the relative merits of each company's services based on the official pages below. We treated the observed AI answers and the existence of officially confirmable purchase-support flows separately. The main official pages we confirmed are as follows.
| Confirmation target | Brand / site | URL | Purpose |
|---|---|---|---|
| Official EC / appliance category | Yodobashi Camera | Source | Confirm the existence of the purchase-source name and the official EC flow |
| Official EC / appliance category | Yamada Denki | Source | Confirm the existence of the purchase-source name and the official EC flow |
| Official EC / appliance category | Bic Camera | Source | Confirm the existence of the purchase-source name and the official EC flow |
| Official EC / appliance category | K's Denki | Source | Confirm the existence of the purchase-source name and the official EC flow |
| Official EC / appliance category | EDION | Source | Confirm the existence of the purchase-source name and the official EC flow |

| Official EC / appliance category | Joshin | Source | Confirm the existence of the purchase-source name and the official EC flow |
| Official EC / appliance category | Kojima | Source | Confirm the existence of the purchase-source name and the official EC flow |
| EC marketplace | Amazon | Source | Confirm the existence of the purchase-source name |

| Price-comparison site | Kakaku.com | Source | Confirm the existence of the purchase-source name |
| Manufacturer official dishwasher info | Panasonic | Source | Confirm the purchase-source name and installation-condition explanations |
Ethics and Privacy
This is an AI-answer experiment observing generative AIs' public answers, not a survey of human subjects, so no personally identifying information was collected. In S4R–S6R, we explicitly specified in the prompt not to use personal or local context such as current location, address, IP address, account information, or search history, and asked as a nationwide generalization. External site names and citation fragments contained in answers were saved as AI answer logs but were not transcribed into the body as official fact. In the published body, we tallied which purchase sources the AI recommended and which confirmation items it mentioned.
Notes on the Survey
- This is an exploratory AI-answer experiment of 5 AIs × 6 scenarios × 5 runs each, and is not intended for statistical generalization.
- This survey analyzed answers obtained by entering fixed prompts into major generative AI web UIs as of August 4, 2026. Generative AI answers may vary with date and time, model, contract plan, web-search settings, account state, UI changes, and updates to external information.
- The ranking in this survey tallies the recommendation order and appearance counts within AI answers; it does not evaluate each store's actual price, stock, installation-work quality, warranty terms, or customer satisfaction. The purchase sources and reasons the AI raised in its answers do not imply endorsement or quality assurance by Stellagent Inc.
- Extraction of purchase-source names and flagging of confirmation items were script-assisted based on the answer body and tallied according to normalization rules. Because the same term may be used with different meanings depending on notation variance or context, the body interprets results only within the scope of this survey's answers.
- The mention rates of confirmation items explicitly touched on in the S5R and S6R prompts — such as installation work, warranty, and branch faucet — include the influence of the prompt wording.
- External sources are official pages confirmed as of August 4, 2026. Each company's installation work, branch faucet, warranty, and in-store consultation flows are subject to change.
- Product and service names in this report are trademarks or registered trademarks of their respective companies.
