This is a Next.js project that helps content creators transform audio recordings and text documents into marketing materials and publish them online.
MktgBuddy is a web application that automates the process of converting audio recordings and text documents into marketing content. Users can upload text documents or audio files, which are then transcribed, analyzed, and transformed into various marketing materials ready for distribution across multiple platforms.
Content creators, marketers, podcasters, and businesses who want to efficiently repurpose audio and text content into marketing materials.
