GenAI Lab vs VanDraw

GenAI Lab is an offline, hands-on course for understanding and prototyping generative AI systems, one experiment at a time. Learn how modern AI actually works by exploring it visually and interactively, right on your iPhone. No internet, no account, no tracking. A GUIDED CURRICULUM The course spans 8 tracks and 52 short missions covering: - GenAI foundations - Transformers and LLMs - Prompt engineering - Retrieval-augmented generation (RAG) - Image generation - Fine-tuning - Evaluation and safety - Multimodal AI and agents Every mission combines a concept check, a matching activity, and a guided Python code fragment so you learn by doing, not just reading. TRANSFORMER ARCADE Six short visual games and six boss challenges bring the internals of transformers to life: - Tokenization - Embeddings - Attention - Multi-head attention - Transformer blocks - Next-token generation Arcade rounds are untimed, offline, replayable, and use deterministic simulations so you can inspect exactly what is happening. LEARN BY EXPERIMENT The built-in simulators use deliberately small, deterministic examples so you can inspect attention weights, prompts, retrieval, diffusion controls, and agent loops step by step. Code activities validate guided fragments to build your intuition; the app does not execute arbitrary code. PRIVATE BY DESIGN Your progress is stored only on your device. GenAI Lab has no account, no ads, no analytics SDK, and makes no network requests. Learn anywhere, even completely offline. WHO IT IS FOR - Students and self-learners exploring how generative AI works - Engineers who want a clear mental model of transformers, LLMs, RAG, and agents - Anyone curious about the ideas behind modern AI, in a focused, no-pressure environment Questions or feedback?

Ever wished you could draw like your favorite artists? With VanDraw, you can — no talent required. Pick a picture, point your phone at a sheet of paper, and the outline appears right on the page. Follow the lines with your pencil. A few minutes later you're holding a real drawing, made by your own hand. HOW IT WORKS 1. Choose a picture from the library — or use your own photo. 2. Point your camera at a blank sheet of paper. 3. VanDraw shows the picture on top of your sheet as a clean outline. Trace what you see, at your own pace. WHAT'S INSIDE • Guided lessons. The next stroke lights up on your sheet and a voice explains it. Steps go in order, and your progress is saved along the way. • A library of hundreds of pictures, sorted by category: anime, animals, places and nature, minimalist line art, characters and cartoons. • Your own photos. Any photo becomes an outline you can project onto paper and trace. • Camera tools that keep the picture steady: image lock, zoom, flashlight, autofocus and opacity control. WHO IT'S FOR • Adults who say "I can't draw." You don't need talent to start — the app leads, you follow, and the result is one you'll want to show someone. • Anime and manga fans who want their favorite characters to come out looking like their favorite characters. The lines are right there on your sheet, so the proportions hold. • Kids and parents. Here the screen is a tool, not the entertainment. The child draws with their own hand, and what remains is a real drawing on real paper. WHY IT WORKS Tracing is how artists have learned for centuries. When your hand repeats a line, it remembers the movement, and each drawing makes the next one easier. Nothing here stays behind glass: every picture you finish lives in your sketchbook, not in a file. Put a sheet of paper on the table, open VanDraw and see what you can draw today.
