UzonCalc is an AI-oriented calculation report authoring tool. It enables AI to help engineers quickly generate and revise calculation reports, so they can be written once and reused indefinitely.

With UzonCalc, you only need to focus on the calculation logic. The framework automatically substitutes variable values, generates calculation steps, renders mathematical formulas, and lays out the document to produce professional calculation reports.

UzonCalc calculation reports are written in native Python syntax without proprietary conventions, making them easy to learn and quick to use.

Combined with AI, UzonCalc can dramatically improve your productivity.

Features

• 🤖 AI-Friendly - Includes a SKILL that lets AI quickly generate and revise calculation reports
• 🐍 Native Python - Uses Python syntax, making it easy to learn yet highly extensible because you can use Python to implement any idea
• 📐 Automatic Formula Rendering - Automatically substitutes variable values and displays calculation steps
• 📌 Automatic Layout - Automatically lays out content according to calculation results, with no manual adjustment required
• 📏 Unit Calculations - Automatically performs unit conversion and dimensional checks, so you do not need to track unit changes during calculation
• 📊 Chart Support - Supports many types of charts through ECharts, SVG, and Matplotlib
• 📋 Excel Reuse - Supports automatically invoking Excel for calculations and extracting results
• 📄 Multiple Output Formats - Uses standard MathML and supports conversion to PDF and Word

Quick Start

Windows

1. Download the software

   Download the win-x64 version from Releases · uyoufu/UzonCalc or the official download page. Extract the archive, then double-click UzonCalc.exe to start.

2. Click "New" to create a calculation report.

   

3. Copy the following code into the main.py file in the new calculation report screen.

   from uzoncalc import *
   
   @uzon_calc()
   async def sheet():
       doc_title("example")
   
       "Hello, UzonCalc!"
   
       w = 10*unit.m
       l = 5*unit.m
       A = w * l

4. Click the Run button to execute it.

   

5. Result

   

CLI

The CLI is primarily intended for calculation report authors. It provides automatic formatting and syntax checks to improve authoring efficiency. When editing calculation reports, VS Code is recommended, together with AI assistance for charts and complex calculation logic.

To use the CLI, follow these steps:

1. Ensure that Python 3.13 or later is installed.

   Check the Python version:

   python --version

2. Create a calculation report file named example.py.

   Add the following content:

   # example.py
   
   from uzoncalc import *
   
   @uzon_calc()
   async def sheet():
       doc_title("example")
   
       "Hello, UzonCalc!"
   
       w = 10*unit.m
       l = 5*unit.m
       A = w * l
   
   if __name__ == "__main__":
       view(sheet)

3. Run it to view the result.

   Run either command in a terminal:

   # Option 1: Run the Python script directly
   python example.py
   
   # Option 2: Use the uzoncalc command
   uzoncalc --serve example.py

   You will see Serving document at: http://127.0.0.1:32180/. Click the URL or open it in a browser to view the result.
