AI-ML Companion - Learn AI & Machine Learning

# AI-ML Companion > AI-ML Companion (https://aimlcompanion.ai) is an interactive platform for learning AI and machine learning. 22 tracks and 300+ hands-on modules span Python and math foundations through deep learning, LLMs, agentic AI, MLOps, and cloud GenAI - taught with live animated visualizations, quizzes, and runnable Python, with narration in English, Hindi, and Spanish. Free tier: 8 complete tracks plus the first module of every premium track. Key facts: - Interactive visualizations, not passive video: learners watch algorithms operate (gradient descent stepping, attention weights lighting up) and experiment directly. - 22 tracks: Foundations, Jupyter & Colab, Python for ML, SQL for Data, Linear Algebra, Probability Theory, Calculus, Optimization, Statistics, Information Theory, ML Algorithms, ML Pipeline, Deep Learning, LLM, Git & Version Control, MLOps & Deployment, Software Engineering for AI, Agentic AI & Multi-Agent Systems, Interview Q&A, AI Tools, AI on Cloud, Forward Deployment Engineering. - Curated learning paths: Data Science and AI Engineering. - Interview preparation: scenario-based Q&A across ML, LLMs, agents, and ML system design. - Works in the browser as an installable PWA (mobile + desktop, offline-capable). ## Docs - [Curriculum](https://aimlcompanion.ai/curriculum): every track with its modules - [Learning Roadmap](https://aimlcompanion.ai/roadmap): structured paths from beginner to ML/AI engineer roles - [Blog](https://aimlcompanion.ai/blog): articles and deep dives on ML, LLMs, and AI agents - [Help & FAQ](https://aimlcompanion.ai/help): how the platform works, free vs premium - [About](https://aimlcompanion.ai/about): what AI-ML Companion is ## Guides - [What is RAG](https://aimlcompanion.ai/guide/what-is-rag) - [Transformer Architecture](https://aimlcompanion.ai/guide/transformer-architecture) - [Agentic AI](https://aimlcompanion.ai/guide/agentic-ai) - [Gradient Descent](https://aimlcompanion.ai/guide/gradient-descent) - [Gener
