Tutorials & Setup Guides
How-to guides for both KuaiJiZi teaching tools: from “how blocks become real C++ code” to “how to read the 3D grammar coordinates”, plus AI setup and troubleshooting.
Learn C++ with blocks
Snap blocks → real C++ code appears → compile and run locally, with topic cards and auto-checked practice.
How do blocks become real C++ code?
Block categories, live code preview and block snapshots explained — plus the three stages that take a learner from dragging blocks to writing code by hand.
Read the guideCompile & run modes: auto / local g++ / remote service
How the desktop build detects a local compiler, when code is sent to a remote compile service, and how to troubleshoot common build errors.
Coming soonHow does automatic practice checking work?
Load a practice project, add reference-answer code and let the app compare console output (✅ match / ❌ mismatch with a side-by-side diff).
Coming soonMake grammar visible
Block sentence building + 3D grammar coordinates + word cards; the core analysis works fully offline.
How to read the 3D grammar coordinates
Subject, predicate, object, predicative, object complement, adverbial, attributive and clause — where each role sits in the 3D view, plus the six sentence-pattern skeletons.
Read the guideWord cards and US/UK pronunciation setup
What each word card contains, how the five reading speeds work, and how to install the Windows speech packs so US and UK accents really sound different.
Coming soonWord-list management and the graded example library
Automatic registration versus manual entries and bulk import, plus how multi-part-of-speech words are disambiguated from context.
Coming soonTurning on the optional AI features
AI is an optional enhancement: DeepSeek (recommended in China) or OpenRouter (international). Keys are stored on your device only.
Where to paste your API key & which model to choose
The exact screens in both apps, recommended models, privacy notes, and what still works when no key is configured.
Read the guideHow to register and get an API key (DeepSeek / OpenRouter)
Sign-up, top-up, key creation and copying — with what to do about leaked keys, 401 errors and insufficient balance.

Both tools are available on Microsoft Store, and their core features work offline.
Learning paths & teaching methods
Practical guides for parents, teachers and self-learners.
C++ or Python first? A practical comparison
Four dimensions, three common routes and a self-check list.
Block-based C++ for beginners: how to start
A 30–45 minute first session and the path to typed code.
How to install g++ on Windows (step by step)
MSYS2 or a standalone build, PATH, verification, troubleshooting.
