About the startup

API where you can generate professional YouTube, Instagram, blog, and Open Graph thumbnails directly inside your existing automation workflows using live datasets and real-time assets. The tool integrates seamlessly with n8n , Make.com , and Zapier , allowing you to create production-ready visuals in under 25 seconds without manual design work. Only the title and image type are required. The API handles the layout, styling, assets, and generation flow automatically. Key features include: Multi-channel support for YouTube, Instagram, blogs, Open Graph, and social media campaigns Output formats in both PNG and WEBP Faceless thumbnail generation Personalized visuals using uploaded photos Brand-ready thumbnails with logos and custom styling Custom datasets support, including your own assets and data sources Automated generation directly inside workflows and pipelines The system uses live datasets from platforms such as YouTube and Google Images to generate more relevant and trend-aware visuals. This helps improve CTR by aligning thumbnails with real-world content patterns while also reducing hallucinations and irrelevant AI-generated elements during image creation. Instead of relying purely on generic AI prompting, the generation process is grounded with contextual live assets and structured datasets for more consistent and accurate outputs.
