WorkZo AI

WorkZo AI is an AI-powered interview practice platform for job seekers who want more than a static question bank. It uses a candidate’s CV, target role, and job description to create voice or text interviews led by an AI interviewer. The system can ask follow-up questions, flag weak answers, and provide feedback on clarity, confidence, relevance, engagement, and a Trust Score. It also includes CV optimization, ATS checking, cover-letter generation, LinkedIn profile review, and resume templates. A free trial is available without a credit card, while the platform also offers plans for bootcamps, universities, training providers, and other organizations.

WhiteBridge AI Academy

WhiteBridge AI Academy is an AI training platform built for small-business owners rather than technical specialists. Its 58 practical courses span 18 industries and can be filtered by business goal, industry, or assistant, including Claude, Gemini, and ChatGPT. A 20-second quiz recommends a starting point, while each course highlights setup time, expected weekly effort, and tool costs. Most publicly listed lessons are marked “Learn for free,” making the platform easy to test before considering its paid clubs or done-for-you services. The approach is intentionally practical: users start with a business task, such as sales follow-up or bookkeeping, and then choose an AI workflow that fits.

AI ROADMAP AND PROGRESS TRACKER

The AI Roadmap and Progress Tracker is a free, structured learning tool offering a 10-month, 40-week curriculum for aspiring AI engineers. It covers essential topics from math and classic ML to PyTorch, Transformers, RAG, fine-tuning, agents, and ML system design. With built-in progress tracking, streak logging, and private data analytics, it's ideal for developers seeking a systematic path into AI.

CraftCourse

CraftCourse is an AI learning path generator that builds a custom curriculum from your goals, skill level, and weekly time budget. It can pull in YouTube, GitHub, Jupyter Notebook, and other formats, and adds an AI tutor named Sage for context-aware help. A pragmatic choice for self-learners tired of one-size-fits-all courses, though pricing and some technical details remain under wraps.

PrepGrind

PrepGrind is a free, interactive browser-based sandbox for mastering system design and data structures & algorithms (DSA). It features a drag-and-drop canvas for architectural diagrams, real-time traffic simulation, and 33 built-in system design case studies. The platform also offers step-by-step animated visualizations for common algorithms, making it an ideal tool for technical interview preparation and foundational architecture learning.

RotLearn
