About

Stacked AI

Features
Read full description

AI Stack Builder is a visual, hands-on learning app designed to help adults and beginners understand how modern artificial intelligence systems actually workβ€”from the computer basics all the way up to running real AI models. Most AI education jumps straight into coding or abstract math. This app takes a different approach: it teaches the entire AI stack, layer by layer, using clear explanations, interactive maps, and practical system-building exercises. What you’ll learn β€’ How CPUs, GPUs, RAM, and VRAM work together β€’ What operating systems, drivers, and runtimes actually do β€’ How CUDA, libraries, and frameworks fit into the AI stack β€’ How containers and Docker are used in real AI deployments β€’ How models, tokens, embeddings, and inference work β€’ Why things breakβ€”and how to reason about common errors Key features Visual Learning Map Progress through a node-based learning map that shows how concepts connect. Each lesson unlocks naturally as you build understanding from the ground up. Stack Builder (Interactive) Assemble AI systems by placing components in the correct order. Learn dependencies, fix broken stacks, and understand why certain setups workβ€”or fail. Short, Focused Lessons Each lesson is designed to be completed in just a few minutes, making it easy to learn consistently without overwhelm. Plain-English Explanations Concepts are explained in clear, practical languageβ€”no advanced math required. Built-in Dictionary Look up common AI terms, abbreviations, file types, and tools, all explained in context and linked to where they sit in the stack. Progress Tracking Track completed lessons, learning streaks, and unlocked topics as you advance. Who this app is for β€’ Adults transitioning into tech or AI β€’ Students learning modern computing systems β€’ Developers who want a clearer mental model of AI infrastructure β€’ Anyone curious about how AI software and hardware work together No prior AI experience is required. AI Stack Builder focuses on understanding systems, not hypeβ€”helping learners build real intuition for how modern AI is structured and used in practice.

MindForge AI makes you fluent in AI. Tokens, embeddings, context windows, RAG, the agent loop β€” the vocabulary and mental models that let you read a real tutorial, follow a real repo, and stop drowning in a field that reinvents itself monthly. Five minutes a day. EVERY PATH ENDS BY SENDING YOU SOMEWHERE ELSE Finish a path and it hands you a concrete thing to go build β€” in a real editor, on your own machine, with a time estimate attached. Not "keep learning!" β€” an actual assignment. This app is the warm-up and the memory layer; the real learning happens in the editor. FOUR PATHS, ONE ARC β€’ AI Fundamentals β€” what these things actually are AI, ML & Deep Learning β€’ LLMs & Prompt Engineering β€” how to talk to them LLM Foundations Β· Prompt Patterns That Work β€’ RAG & Embeddings β€” how to give them your data Embeddings Explained Β· Your First RAG Pipeline β€’ AI Agents β€” how to let them act The Agent Loop Six courses. Bite-size lessons that teach exactly one idea and bust one misconception beginners actually have β€” "RAG teaches the model" (it doesn't), "the model runs your tools" (it doesn't). Interactive quizzes build toward boss exams; pass one and earn a certificate with a completion code. EXPLAIN β€” A PLAIN-ENGLISH CONCEPT LIBRARY Nine core ideas β€” LLMs, neural networks, transformers, hallucination, embeddings, RAG, fine-tuning, agents, and MCP β€” each written out in plain English, browsable and searchable, with a "go deeper" technical version for when you want it. Hand-written, not generated. No chat, no model to wait on, no quota β€” free to read. READ CODE WITHOUT FEAR A built-in playground and a library of challenges with test cases. Run it, break it, fix it, see what the error actually means. The goal is literacy β€” being able to open a real repo and know what you are looking at. REMEMBER WHAT YOU LEARN Spaced-repetition flashcards (the same SM-2 method behind Anki) resurface concepts right before you'd forget them. Fluency is a memory problem, and this is the part of learning an app is genuinely good at. LEARNING THAT STICKS Streaks, XP, levels, daily quests, achievements, and leaderboards turn five minutes a day into a habit you keep. And Embry β€” the small anxious robot who runs the place β€” will have feelings about your streak. WHAT YOU GET, FREE Three lessons and fifteen code runs every day, plus the entire Explain library β€” free to read. The app is ad-supported and runs on your device β€” no account, no sign-up, no backend. Get fluent β€” then go build the thing.
