I used pure C++.</p> <p>Why?</p> <ul> <li>Starts in &lt;1 second (Python takes 5-6 sec)</li> <li>Uses 10x less RAM</li> <li>Runs 100% offline — no API, no cloud, your data never leaves PC</li> <li>Voice + Chat + PC Automation like real JARVIS</li> </ul> <p>I built it for myself, but 20 friends wanted it. So I'm selling lifetime license for $50 one-time, not monthly.</p> <p>This is not a wrapper. It's 15k+ lines of pure C++.</p> <p>Tech stack:</p> <ul> <li>Pure C++ (C++17/20)</li> <li>Local STT/TTS, no OpenAI needed after install</li> <li>Windows native, fast, works on old laptops</li> </ul> <p>GitHub: <a href="https://github.com/gandhiprey13/FRIDAY-STARK-OS" rel="noopener noreferrer">https://github.com/gandhiprey13/FRIDAY-STARK-OS</a><br> Demo + Lifetime access: Click Sponsor button on GitHub (Dodo Payments)</p> <p>I'm 19, self-taught from Surat.
