Bloom / Beebo — Matthew Jörke & Emma Brunskill (Stanford)
Shows an AI advisor that helps real people own their health goals rather than dictate them — a counter-model to optimization-obsessed wellness tech.
Stanford grad student Matthew Jörke and Prof. Emma Brunskill built Bloom, an LLM-coached fitness app whose agent 'Beebo' uses motivational interviewing instead of prescriptive plans. In a 4-week field study with 54 users, the LLM version shifted people's mindsets toward sustainable activity. Won Best Paper at CHI 2026.
