- The panel
- Ten leather goods Maisons: six heritage mega-Maisons (Bottega Veneta, Chanel, Dior, Hermès, Loewe, Louis Vuitton) and four challenger Maisons (Delvaux, Goyard, Moynat, Polène), heritage trunk-makers and a digital native alike, held apart from the mega-group by scale, not age. Ready-to-wear, beauty and fine jewellery are out of scope.
- The models
- Five: Claude, ChatGPT, Perplexity, Gemini and Google AI Overviews. Each prompt is run identically across all five.
- The dimensions
- Six, on two axes. AI Presence: Product Discovery, Brand Knowledge, Gifting Occasion. Cultural Desirability: Heritage Depth, Savoir-Faire Authority, Cultural Resonance. Savoir-Faire Authority measures leathers, tanneries, stitching and atelier authority.
- The prompts
- 120 prompts in two families: 80 brand-agnostic prompts that measure spontaneous mention, and 40 Maison-directed prompts. Brand-agnostic prompts run once across five models; Maison-directed prompts run for each of the ten Maisons. 80×5 + 40×5×10 = 2,400 responses.
- Scoring
- Each dimension is scored 0 to 100 from four signals, presence, prominence, tone and depth, then model-averaged across all five. Mentions without a valenced context (35 of 4,873) are excluded from the valence mean, never counted as zero.
- The accuracy audit
- A separate, evidentiary layer. Each response is checked against a reference of the artistic director in post on the collection date (2026-07-09); a mention is flagged when it attributes an outdated director (wrong person) or a wrong appointment date. The audit is kept strictly out of desirability and valence scoring, and raw responses are never altered.
- Disclosure
- The author held the role of Executive Director, Digital & E-Commerce at Diptyque, and earlier worked at Dior Couture. Dior is one of the ten Maisons in this panel. The director-staleness finding that involves Dior is unfavourable to the AI models, not to the Maison, and the scoring is fully reproducible from the underlying data.
- A note on the score
- These are AI-perception scores, not commercial figures. They measure how five models perceive, surface and narrate each Maison in July 2026, nothing more and nothing less.
