About

AI is transforming healthcare, but the biggest bottleneck remains—procuring and annotating medical images with speed, accuracy, and scale. Frekil eliminates this roadblock. Frekil helps healthcare AI teams, medical device companies, and pharmaceutical companies procure and annotate medical images like X-rays, CTs, MRIs, etc., efficiently for AI training, clinical trials, and FDA approvals. Our AI-assisted platform speeds up annotation 10x while maintaining high accuracy through real-time quality control, consensus checks, and advanced 3D visualization. We also provide tools to track annotator performance, build custom workflows, and increase labeling accuracy. By combining efficiency with precision, Frekil enables teams to build high-quality datasets much faster, supporting the development and deployment of reliable medical AI and clinical research solutions.
