Stanford Team Unveils AromaGen: AI System for Real-Time Scent Transmission

Stanford's Percy Liang team has released AromaGen, an "AI-generated scent" system that claims to enable universal, real-time odor transmission: photograph a cup of coffee or describe a place in text, and someone on the other side of the world wearing the companion necklace can smell the corresponding scent.

Confirmed

Core method: a multimodal AI model is trained to decompose any input (a photo or text description) into mixture ratios of 12 base scents, which the wearable device then releases in real time according to the inferred blend; the language model's internal knowledge enables generalization to novel foods and beverages.
Results: in a three-way blind test covering 50 common foods and drinks across 12 scent categories, participants identified AI-generated scents correctly 71% of the time — more than double the 33% random baseline; users rated the generated scents' realism at 4.65/7 on average.

Why it matters

Scent is highly personal, subjective and hard to put into words, long making it a stubborn challenge for digital transmission; AromaGen's approach — decomposing into 12 base scents plus wearable release — offers a generalizable path forward.
If the approach matures, it could add an olfactory channel to remote communication, immersive entertainment and e-commerce smell-based shopping, complementing sight and sound, while also informing multimodal representation research on odor.
