About EngiLipi

EngiLipi is a free place to learn engineering by doing. It brings programming, computer science, electronics, embedded systems and the core engineering branches together in one workspace, so you can read a concept, try it in a simulator or calculator, write the code and test yourself — without switching sites.

What you will find here

• Complete courses for more than 70 programming languages, from C, Python and Java to Rust, Go, Haskell, COBOL and Solidity, organised from basics to advanced.
• Computer-science tracks: data structures and algorithms, operating systems and architecture, compilers, memory, concurrency, security and more.
• Structured lessons for engineering branches such as electrical, mechanical, civil, electronics, chemical, aerospace and many others, with worked examples and formulas.
• Engineering calculators that show the formula, the substituted values and an explanation, and interactive simulators for logic circuits, SPI, I²C, UART, CAN, RTOS scheduling and microcontrollers.
• Code Studio for writing, running and testing code in the browser, coding practice problems, a project atlas and interview preparation for every branch.

How it works

Everything runs in your browser. Your progress, completed lessons and settings are saved on your own device (and, if you sign in, to your account so they follow you to other devices), and the EngiLipi AI assistant answers from the site's own lessons without sending your questions anywhere.

The name comes from lipi, the word for script or writing in Sanskrit and Hindi. EngiLipi is the script of engineering: the place to learn to read and write its language, from formulas to code.

The site is free to use. It is supported by advertising.

We work hard to keep the lessons accurate, but mistakes happen. If you spot one, please tell us through the contact page — corrections are always welcome.
