This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass

What I Built

Cortex AI Puzzles is an adaptive, interactive puzzle platform designed to challenge cognitive thinking while breaking the cycle of endless digital doomscrolling.

Instead of keeping users glued to a screen with addictive loops, the app delivers short, engaging puzzles and outdoor-inspired observation challenges. The idea is simple: spend a few focused minutes exercising your mind, finish a round, and step away to "touch grass" and explore the physical world. It is built for puzzle lovers, students, and curious thinkers seeking mindful digital breaks.

How I Built It

Hosting & Infrastructure: Deployed as a web service on Render, delivering fast response times and dependable uptime without complex infrastructure management.
Open-Source AI Foundation: Built around open-source AI frameworks and open-weight models to orchestrate procedural puzzle generation, evaluate player solutions, and adjust riddle difficulty dynamically.
Clean UI/UX: Crafted with a clean, lightweight interface to ensure fast load times and make screen interactions concise, intentional, and distraction-free.

Why Does Open Innovation Matter?

Relying on closed, proprietary APIs introduces unpredictable pricing shifts, telemetry risks, and vendor lock-in. Open innovation makes Cortex AI Puzzles:

Independent & Accessible: The application can run on open models without ongoing per-token commercial tolls, ensuring the project remains accessible to everyone.
Privacy-Respecting: Users can solve problems without their inputs being collected for ad profiling.
Extensible: The community can easily fork the repository, integrate offline local LLMs (via Ollama or llama.cpp), or contribute new outdoor-themed puzzle packs.
