ProjectCortex — AI Browser Co-Pilot that Goes Where You Go

ProjectCortex stands out by putting an AI co-pilot directly inside your browser — no tabs, no copying/pasting, no context switching. Just highlight and It intelligently summarizes, fact-checks, defines, and answers questions about any web page with built-in smart fallback across Groq and OpenRouter. </>

Key Features:
AI Co-pilot Panel : A draggable glassmorphic UI that lives on any page, offering 1-click summarization, instant fact-checking, context-aware definitions, MCQ solving, and free-form Q&A with typewriter streaming.
Smart Selection Bubble : Highlight any text on any website and get an instant contextual action menu — summarize, define, or fact-check without lifting your hands from the mouse.

Dual AI Provider Architecture : Auto-routes between Groq and OpenRouter free tiers with multi-model fallback chains (Llama 3.3 → Gemma 2 → Mixtral → DeepSeek) — zero downtime, zero configuration.

Full SaaS Backend : JWT-based hardware-bound licensing, admin dashboard for license lifecycle management, version control, API logs, and user feedback — all powered by Next.js + Supabase + Prisma.
Supported Languages: Python, JavaScript/TypeScript, Go, Rust, Java, C++, Ruby, PHP, and more.

AI Providers: Groq (primary), OpenRouter (fallback), plus any OpenAI-compatible custom endpoint.

Licensing: Hardware-bound JWT license keys with 24-hour offline grace period, periodic auth verification, and full admin CRUD console.

Built with: Chrome Extensions MV3, Next.js 16, React 19, Supabase, Prisma, PostgreSQL, Groq API, OpenRouter API, WebGL fingerprinting, MutationObserver, Turbopack, and javascript-obfuscator.
License: MIT — open source, self-hostable, extensible.
