Train modern CS, programming, systems, AI, DSA, security, and product engineering skills with short lessons, active recall, and private local-first tutoring. Ouxa is a mobile learning app for modern computer science, programming, and real-world software engineering. Learn through short lessons, active recall, concept cards, quick checks, daily review, XP, streaks, hearts, achievements, and private AI-assisted hints. Ouxa is built for serious learners who want practical engineering fluency, not passive tutorial scrolling. Ouxa focuses on the skills developers use today: programming languages, algorithms, CS fundamentals, local-first tools, terminal workflows, production debugging, software architecture, AI-native product work, and system design judgment. Tracks include: Rust: memory safety, ownership, borrowing, systems programming, performance, and practical backend foundations. Python: clean syntax, scripting, automation, data structures, backend patterns, and applied programming fluency. TypeScript: typed JavaScript, frontend/backend patterns, API contracts, async programming, and production code organization. Node.js: JavaScript backends, server runtime behavior, APIs, package workflows, deployment habits, and production debugging. Go: simple concurrent programming, services, tooling, backend systems, and practical infrastructure code. C++: low-level programming, performance, memory, compiled systems, and modern C++ engineering basics. LLM Apps: prompt structure, API usage, tool calling, retrieval concepts, AI product workflows, and safe AI-native software design. Data Structures and Algorithms: arrays, strings, hash maps, trees, graphs, recursion, dynamic programming, complexity, and interview-style problem solving. CS Math: discrete math, logic, probability, combinatorics, graphs, number systems, and the math behind algorithms and computing. Core CS: operating systems, compilers, databases, networking basics, memory, concurrency, and computer science foundations. Systems Architecture: system design, scalability, reliability, queues, caching, observability, failure modes, and tradeoff analysis. Distributed Systems: replication, consensus concepts, consistency, coordination, latency, fault tolerance, and distributed design patterns. Networking: protocols, DNS, HTTP, TCP/IP, SSH, ports, routing concepts, debugging, and production connectivity. Developer Systems: terminal workflows, Git, CI, deployments, logs, observability, incident response, and real-world developer operations. Product Engineering: user-facing software, product thinking, UX tradeoffs, iteration, analytics judgment, and shipping useful features. Cybersecurity: security basics, threat modeling, authentication concepts, vulnerabilities, secure coding habits, and defensive engineering. The tutor is local-first. Ouxa can work with deterministic offline hints, optional on-device model downloads, and an optional private LAN model server for advanced users. Normal learners do not need a cloud AI account or paid API key. Privacy and access: - No required account - Privacy-first progress storage - No forced ads - No subscriptions - Free foundation lessons - Optional one-time purchases for advanced Mastery depth - Purchases restore with the same App Store account Ouxa is free to start. Foundation lessons stay useful before purchase. Advanced Mastery lessons use a one-time purchase model: standalone mastery packs unlock deeper advanced lessons for specific tracks, while Founder Lifetime Unlock unlocks broader paid depth in the app. Ouxa is for developers, computer science learners, self-taught programmers, students, interview prep, and builders who want to train real engineering skill one focused session at a time. Local AI note: Ouxa includes optional on-device model support for richer hints on capable phones. Local inference speed and quality depend on your device, available memory, selected model, and current context. If a model is unavailable, slow, or not suitable for the task, Ouxa falls back to deterministic offline hints so core learning still works without a cloud AI account.
