Xplain is an open-source AI assistant with one smart input box. You type, paste or attach something, and it decides what to do with it.

Code tutor: paste code in any language. It names the language, explains each line in simple words, and shows step by step how the output is produced. It adds an interactive execution tree, a flowchart or an image only when they actually help, plus a short quiz and a beginner glossary.
File actions: upload a screenshot, PDF or document, and it turns it into options. A bill becomes “Explain” or “Pay”, which opens the payment page. A note saying “email this person” opens Gmail with the address already filled in. You can also add a due-date reminder or export the data to CSV or Excel.

It’s built for beginners, in Arabic (Modern Standard Arabic) first, plus English and Turkish. It runs Gemma 4 locally through Ollama, so there’s no API key, no cost, and your code and files never leave your computer. Built with Python and Streamlit, MIT-licensed.
