SK Telecom Newsroom released three winning entries from its "Everyone's Promp.T" Life AX (AI transformation in daily life) prompt contest, showcasing solutions for everyday inconveniences such as suspicious text messages, mobile carrier membership benefits, and malicious comment management [1].

What happened

• SK Telecom Newsroom announced three Life AX category winners on September 1, 2026 [1].

• The contest received a total of 480 entries [1].

• Three winning prompts were selected for solving everyday inconveniences through structured AI design [1].

Why it matters

The contest is part of SK Telecom Newsroom's "Good Change" campaign, which aims to drive work and cultural innovation through AI transformation (AX) and rebuild trust through customer value innovation [1]. Following a first installment featuring Work AX winners who solved workplace problems, this second installment focuses on Life AX solutions for daily life [1]. Global readers should note that prompt engineering involves structuring text instructions to guide artificial intelligence to perform specific, multi-step reasoning tasks rather than just giving direct, single answers.
