## What is MindForge AI?

MindForge AI makes you fluent in AI. Tokens, embeddings, context windows, RAG, the agent loop — 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 — in a real editor, on your own machine, with a time estimate attached. Not "keep learning!" — an actual assignment. This app is the warm-up and the memory layer; the real learning happens in the editor.

FOUR PATHS, ONE ARC
• AI Fundamentals — what these things actually are
   AI, ML & Deep Learning
• LLMs & Prompt Engineering — how to talk to them
   LLM Foundations · Prompt Patterns That Work
• RAG & Embeddings — how to give them your data
   Embeddings Explained · Your First RAG Pipeline
• AI Agents — 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 — "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 — A PLAIN-ENGLISH CONCEPT LIBRARY
Nine core ideas — LLMs, neural networks, transformers, hallucination, embeddings, RAG, fine-tuning, agents, and MCP — 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 — 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 — 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 — the small anxious robot who runs the place — will have feelings about your streak.

WHAT YOU GET, FREE
Three lessons and fifteen code runs every day, plus the entire Explain library — free to read. The app is ad-supported and runs on your device — no account, no sign-up, no backend.

Get fluent — then go build the thing.

## Version history (last 3 releases)

### 1.9.2 — 2026-08-20

Version 1.9.2 completes MindForge's premium Embry redesign. It adds a full-body mascot throughout the app, an animated branded launch, 221 synchronized and captioned lesson and feedback narrations, and a richer Arc Furnace path with checkpoints, chests, and practice states. Agent Loop lessons now cover durable graph state, routing, checkpoints, human approval, evaluator loops, parallel fan-out, and orchestrator-worker patterns. On-device translation supports 59 languages, including Spanish, Hindi, and Chinese. Purchases, consent, ad reliability, accessibility, and performance are also improved.

### 1.9.1 — 2026-08-18

Version 1.9.1 gives Embry the whole experience: refreshed launcher and in-app branding, an animated launch transition with reduced-motion support, narrated and captioned course pass/fail videos, and a richer winding lesson map with checkpoints, unit chests, practice-needed states, and Embry at the active stop. Agent Loop lessons now cover durable graph state, routing, checkpoints, human approval, evaluator loops, parallel fan-out, and orchestrator-worker patterns. Ad startup is more reliable.

### 1.9.0 — 2026-08-17

No release notes.
