Borrowed Brain
A searchable personal knowledge handoff tool for people who repeatedly explain the same niche process to friends, clients, family, coworkers, or online communities. Users record a quick voice note or write a short answer, then the app converts it into a reusable “brain card” containing the explanation, links, caveats, and follow-up questions. Examples include explaining how to use a camera setup, care for a pet, run a club event, configure software, or follow a favorite recipe. Unlike a generic notes app, it is optimized for sharing repeat answers and tracking which explanations confuse people. It can be built incrementally with transcription, card templates, public/private links, and basic analytics.
