MI Diaries is an app developed by Michigan State University as part of the MI Diaries project. The app is dedicated to collecting audio diaries from residents of Michigan aged 3 and above during and post-lockdown periods. Participants can sign up for the project on the official website. Diarists receive regular email prompts with questions like "What headline caught your attention this week?" to inspire diary entries.

Users have the flexibility to choose which prompts to respond to or share about their day. Additionally, diarists can opt to have their stories featured on the MI Diaries website, showcasing a snapshot of their experiences. The app serves as a platform for individuals to document and share their daily lives during significant times.
