ReelDone — Demo video

ReelDone is an AI-powered social publishing agent designed to eliminate repetitive content work for creators. A creator uploads one video and provides one idea or script. ReelDone uses Meta Muse Spark 1.3 through a Modal-powered inference pipeline to generate platform-specific content instead of copying one generic caption everywhere. From a single input, ReelDone creates YouTube titles, descriptions, keywords and tags; Instagram and Facebook captions and hashtags; LinkedIn professional copy; and adapted content for Pinterest and X. ReelDone also includes AI-powered posting-time recommendations based on the creator's content topic and niche. Facebook is the real API integration in this hackathon build, including authentication, Page authorization and real video publishing through the Facebook Graph API. Other social connectors and future scheduled publishing are transparently presented as Demo functionality. ReelDone's goal is simple: let creators spend their time creating instead of repeating publishing work.
