Audio_Cards vs GenAI Lab

Audio Cards is a completely free flashcard app built for learners who want to study without interacting with thier screen. Hear the front and back of each card with high-quality text-to-speech, then rate your recall with Anki-style spaced repetition. Enable hands-free mode and review by voice: flip, repeat, again, hard, good, easy, pause, and end. Hands-free review — Voice commands during study sessions (microphone used only when hands-free is on). Spaced repetition — SM-2 scheduling with Again, Hard, Good, and Easy. Fully offline — Decks and review history stay on your device. No account required. Import your decks — CSV paste/file import and Anki .apkg import (text/images; cloze not supported). Stats — Daily reviews, streaks, due forecast, and deck-level charts. Touch controls are always available. Permissions for microphone and speech recognition are requested when you turn on hands-free mode.

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?
