Educative is an online learning platform built around interactive, text-based coding courses and browser-based practice for developers and tech professionals. Its library covers system design, generative AI, web development, machine learning and data science, with programming topics including Python, JavaScript, Java, SQL, C++, C and Go. Learners can use coding exercises and challenges, projects in preconfigured environments and AWS Cloud Labs. Coding assistance includes personalized hints and feedback, an integrated debugger, assessment feedback, roadmaps and an AI tutor that generates tutorials with executable code and diagrams. Interview preparation includes Grokking courses, personalized prep plans, AI mock interviews and an interview coach. Educative says every course has free lessons and offers some interactive free courses. Individual trials last 21 days and exclude interview preparation courses. Educative Go is free to download, though some courses and features require an active subscription; its selected mobile course content is optimized for review, and course progress does not sync between mobile and desktop. Enterprise is for software engineering teams, with custom onboarding plans, task and blocker notifications, progress dashboards and connections to Confluence and documentation. Subscribers can cancel auto-renewal but are not refunded for the paid period.
