Cortex AI
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

Cortex is an Open-Source, Autonomous AI Operating System that bridges the gap between LLM intelligence and OS-level execution. Current AI assistants are trapped inside browsers, but Cortex actually controls your PC, executes terminal commands, debugs its own code, and interacts with GUI elements. In our hackathon demo, Cortex autonomously clones a GitHub repository (QuixBugs), reads the code, identifies a logical bug in a Quicksort algorithm, fixes the code using its file-editing tools, and runs a pytest suite to verify the fix (13 tests passed). Finally, using OCR + Windows UIA (Computer Vision), it opens Notepad, types a detailed bug report, and saves it to the desktop. Key features include: 1. Real-time Mid-Execution Interruption (Live Feedback). 2. Truncation Self-Correction (Detects broken JSON streams and self-heals). 3. GUI Grounding (Set-of-Mark prompting to click UI elements like a human). 4. 13 specialized OS tools (Terminal, GUI, Email, WhatsApp, Telegram, Files).
