The original title is "Cortexa: a free open-access search engine for ML and robotics papers"
Original: # I got tired of hunting for free ML/robotics papers across 5 sites, so I built an aggregator
Short summary
A final-year engineering student built Cortexa, a free open-access-only search engine for robotics, ML, and AI papers aggregated from arXiv and CrossRef. The project runs on Next.js 16, TypeScript, Tailwind CSS v4, and Supabase. Key challenges included fixing misdirected PDF links and navigating complex open-access licensing rules across publishers.
- •Cortexa aggregates open-access ML/robotics papers from arXiv and CrossRef
- •Built with Next.js 16, TypeScript, Tailwind v4, Supabase
- •Licensing and PDF link resolution were the hardest problems
Generated with AI, which can make mistakes.
