OneCompiler · Online programming lab
Write, learn, run.
Use the embedded OneCompiler editor to write code in a supported language and run it online. Study Hub AI can help draft, explain, or improve code; review its suggestion before loading it into the editor.
Keep your work safe: Code is sent to OneCompiler when you choose Run. The AI helper only receives the task and any code you explicitly paste into its context box; those requests are saved in your Study Hub chat history. Do not include passwords, API keys, or private data. AI-generated code is never run automatically.
