ContentDNA — Creative Fingerprint Engine

ContentDNA is a multimodal AI application that generates a unique creative fingerprint for any media content. Just like DNA reveals a person's identity, ContentDNA reveals the hidden creative identity of your work. Upload an image, video, or audio file and instantly receive a deep structured analysis: a DNA Score (0–100 distinctiveness rating), a 5-dimensional mood profile (energetic, optimistic, cinematic, melancholic, intense), pacing and rhythm analysis (cut rate, BPM, visual density), a style fingerprint with 8 descriptive tags, color palette breakdown, the top 3 real-world creative references it most closely resembles with match scores, target audience prediction (age range, lifestyle, best platform), and a plain-language AI creative brief. The application is built on a React 18 + Vite frontend with a Node.js + Express backend. Media preprocessing uses ffmpeg for video frame extraction and Sharp for image optimization. The AI vision layer uses Gemini 1.5 Flash for multimodal understanding across image, video, and audio inputs — architected to run on AMD Instinct MI300X via ROCm and Qwen-VL when AMD Developer Cloud credits are provisioned. ContentDNA targets filmmakers, content creators, brand teams, and audio producers who need to understand the emotional and stylistic DNA of their creative work in seconds. The project is fully open-source and deployed as a Hugging Face Space.
