Exam Samurai is specifically designed for exam preparation, offering features like instant exam generation, real-time grading, and a tracking dashboard. It is tailored to help students convert their study materials into practice exams and improve their knowledge retention. On the other hand, Lightning AI is a platform focused on deep learning and AI model training, not exam preparation. Therefore, Exam Samurai is more suitable for students looking to enhance their exam preparation process.

Lightning AI is specialized in AI model training, providing an end-to-end platform for training, finetuning, and deploying AI models. It supports scaling models across multiple GPUs and facilitates team collaboration on the cloud. Exam Samurai, however, is focused on exam preparation and does not offer AI model training capabilities. Thus, Lightning AI is the better choice for AI model training purposes.
