Show HN: A metadata-driven UI for comparing AI image and video models

- Vioevo is a new web tool that lets users visually compare outputs from different AI image and video generation models side-by-side, using metadata (prompts, settings, model names) to organize the comparisons. - It was posted on "Show HN" (Hacker News), a common place where makers share projects for feedback from the tech community. - The rise of models like Midjourney, DALL-E, Stable Diffusion, and newer video generators (Runway, Pika, Sora, etc.) has created a need for side-by-side testing, since results vary greatly by prompt and model version. - Metadata-driven means the tool reads the parameters embedded in each generated file—rather than relying on manual tagging—to automatically display what prompt, settings, and model were used, making comparisons systematic rather than manual.
