L'Oréal cut content costs 40% with OpenAI and is routing product discovery through ChatGPT. The same week, a Fractl study shows consumers using AI search more but trusting it far less. The funnel is moving into the assistant just as faith in its answers slips.
The AI-marketing pitch split in two this week. At VivaTech, L'Oréal and OpenAI signed a deal that routes product discovery, virtual try-on, and ad pilots straight through ChatGPT — the clearest sign yet that the assistant is becoming the storefront, not just a research stop on the way to one. The same week, a fresh Fractl study told marketers the quiet part out loud: people are leaning on AI search harder than ever, but the share who find it more helpful is collapsing. So the funnel is moving into the assistant exactly as faith in the assistant's answers slips — which means the brands that win here are the ones feeding it clean, verifiable, first-party data rather than hoping it scrapes them favorably. Build for the assistant; don't assume its answers still carry the trust they did a year ago.

Key Takeaways
The funnel is moving inside the chatbot. L'Oréal is feeding product data directly to ChatGPT so it doesn't scrape the web — if you sell anything, your product feed is now an AI input, not just a webpage.
Trust in AI answers is falling fast. The share of consumers who find AI search more helpful dropped from 82% to 54% in a year, even as usage rose — original research and named experts now beat AI-scaled content.
Proprietary data and named experts are the durable edge. AI can't fabricate first-party numbers or a real person's byline, so the assets LLMs can't synthesize are the ones worth investing in.
The ad infrastructure is hardening fast. At Cannes, Criteo, Taboola, and Higgsfield showed AI moving from a creative tool to the operating layer of campaign delivery — the plumbing, not the gimmick.
Accuracy beats scale. As agents make automated decisions at volume, a dirty dataset compounds errors — clean, verified data is the new competitive edge.
The Big Story
L'Oréal accelerates generative AI content engine with fresh OpenAI deal · Digiday · June 19, 2026
-> L'Oréal's CreAItech platform has already cut production costs 40% and crafted 50,000 marketing assets, and the new OpenAI deal extends GPT models across content, commerce, and discovery. Maybelline is set to bring its ModiFace virtual try-on directly into ChatGPT, while L'Oréal feeds up-to-date product data to OpenAI so the assistant answers from the brand's own feed rather than the open web. With €1.5B in 2025 tech investment and ~60% of its ad budget in paid social, L'Oréal is the clearest enterprise template for routing the whole funnel through an assistant — so audit whether your own product feed is structured for AI retrieval.
