Programming path

KuaiJiZi C++ Tutor · Learning Path

From the first look at the interface to project practice — master C++ step by step with blocks.

1

Get to know the block interface

Install KuaiJiZi C++ Tutor from Microsoft Store, then explore the layout: the block toolbox, the build area and the code preview. Learn the block categories and colours.

Install from Microsoft Store User manual
2

Core programming concepts

Learn variables, input/output, loops and conditions with blocks. Snap and run — no hand-written code needed — and build programming thinking first.

Practice: basic blocks Tip: ~30 min a day
3

Blocks ↔ C++ code

Watch each block generate its C++ code in real time. Learn how logic maps to syntax, until you can read and write code with and without blocks.

Real-time code preview Search the toolbox
4

Functions, arrays & algorithms

Study functions, arrays and common algorithmic thinking, and use AI-assisted analysis to understand the ideas behind your code.

AI-assisted analysis Algorithms & data structures
5

Projects & practice

Combine everything in small projects — from a simple calculator to a mini game — and experience the whole build flow.

FAQ

Programming FAQ

How do I install KuaiJiZi C++ Tutor?
Open Microsoft Store, search for “KuaiJiZi C++ Tutor” or use the Store button on our product page, then click “Get / Install”. Launch it from the Start menu afterwards.
I've never programmed. Can I start?
Yes. The tool is built on drag-and-drop blocks, so no syntax memory is needed to produce runnable C++ programs. Code is generated in real time as you build — progress step by step.
How are blocks related to C++ code?
Each block maps to a piece of C++ syntax. Code updates live on the right as you snap blocks, so the relationship between logic and syntax stays visible.
How do I use the AI analysis?
Choose AI analysis in the code view and it will interpret your logic and suggest improvements — like an on-call programming tutor.
Which systems are supported?
The desktop version is distributed through Microsoft Store and supports Windows 10 and later (64-bit).
Where can I get help?
Check the user manual first; for personal support, scan the support QR code at the bottom of the page or email 48456900@qq.com.
English path

Kuaijizi 3D English Blocks · Learning Path

Start by building with blocks, understand structure with 3D grammar coordinates, then consolidate with word cards and word lists.

1

Meet the tool & free building

Install and open the app, then enter “Free building” (the block editor). The left toolbox is organised by grammar: phonics, sentence patterns, word classes, phrases and expressions, sentence components. Drag a “sentence frame” block and snap component blocks into its slots to build a sentence.

5 toolbox categories 🔊 Listen
2

Basic patterns & graded sentences

Browse the 80 graded sample sentences in “Project learning” — from basic patterns (subject-link-verb, SVO) to clauses, compound sentences, passives and emphasis. Send a sample into Free Building to see its block structure.

80 sentences Beginner → advanced grading
3

3D grammar coordinate analysis

Send a sentence to “3D analysis”: X = word class, Y = sentence role, Z = phrase & clause structure. Rotate the view, zoom, and let word spheres hang at their levels — grammar becomes structure you see. Use the static engine offline or AI analysis for more depth.

3D coordinates AI analysis / static engine
4

Word cards & vocabulary manager

Words you use while building are collected automatically and become one-tap word cards: phonetics, meanings, examples, word roots, derivatives, collocations, synonyms — with audio and archiving. Manage built-in, custom and add-on word lists (e.g. 3500 high-frequency words).

Word cards Three-layer word lists
5

Project learning & daily practice

Create your own sentence projects in “Project learning” (set a grade pattern, import/export block JSON), and keep typical sentences archived. Switch US/UK audio and reading speed, set your default view — build a few sentences and inspect a few 3D structures every day.

FAQ

English FAQ

What English levels is it for?
The tool supports English grammar learners from zero to advanced. Beginners can start with playful block-building; more experienced learners use 3D analysis and graded sentences to tackle complex structures.
What do the three 3D axes mean?
X = word class (what kind of word), Y = sentence role (subject, predicate, object…), Z = phrase & clause structure (single word or part of a phrase/clause). The axes are colour-coded red / green / blue so directions are easy to tell apart.
How does AI analysis work? Is it paid?
AI analysis needs an API key from a service provider (we recommend DeepSeek; the app is tuned for deepseek-chat / deepseek-v4-flash). Keys are stored locally only and never uploaded; usage fees are charged by the provider. Without a key, the built-in offline static engine still produces 3D analysis. API Key Guide
No sound when reading?
Check the system volume and the reading speed (too slow can sound stuck). On Windows make sure an English voice pack (US/UK) is installed; on Android check that a system TTS engine is available (Settings → Accessibility → Text-to-speech).
The interface language does not change?
Choose a language manually in Settings once — it stays. If you never chose one, the app follows your system language (when it is one of the 8); Arabic switches automatically to right-to-left layout.
Will my data be lost? How to back up?
Data is stored locally first and never uploaded. In Settings → Main folder you can bind a custom folder (a USB drive or sync folder); copying the folder is a complete backup. Back up before uninstalling.
Which platforms are supported?
Windows desktop (MSIX, Windows 10 1809+ 64-bit, WebView2) and Android tablets (Android 7.0+, best on 10"+). Both platforms share the same core logic.
