Planana AI
Prepare for coding interviews with daily lessons and practice shaped by your target role.
Interactive developer courses, system design, and interview preparation

Educative provides interactive technical learning for software developers. Courses cover programming, system design, cloud services, AI engineering, and interview preparation. Explanations and browser-based exercises let learners study a concept and try code within the lesson.
Learning sequences and practical work organize related subjects, while an AI tutor assists during study. Mock interviews provide practice with technical questions, and code feedback helps a learner inspect a submitted solution. The catalog includes both foundations and topics such as distributed systems, language models, and agent architectures, allowing developers to select material for a new subject or a forthcoming interview.
