I Built FRIDAY AI (Iron Man) in Pure C++ - Fully Offline, No Python

I built FRIDAY - Iron Man's AI - but fully offline in C++ from Navsari, Gujarat.

No Python. No internet needed for core features.

I was tired of Python assistants that lag and need internet for everything. So I built one that runs 100% on my laptop.

Tech Stack:

• C++17 - Pure, no external dependencies
• Win32 SAPI 5.4 for voice input/output
• Multithreading for non-blocking speech
• Win32 API for system controls

Features I shipped in v14.0:

• Battery percentage voice report - "Battery at 85 percent"
• Voice time / date / weather
• Opens YouTube / Google with voice - "Open YouTube"
• Wikipedia search + maths solver
• STARK-43 L1-L4 shutdown protocol
• Non-blocking voice - You can interrupt it while it speaks

The hardest part - Non-blocking voice:

SAPI blocks by default. I fixed it with threading and a speech queue.

cpp
// My non-blocking core
void speakAsync(const std::string& text) {
    std::thread([text]() {
        pVoice->Speak(text.c_str(), 0, NULL);
    }).detach();
}

while (true) {
    listen();
    if (command) speakAsync(response);
}
