CyberTools Hub AI: Building a Privacy-First AI Security Log Analyzer with Open-Weight AI

LedgerShield is a local-first receipt and invoice categoriser for freelancers and micro-business owners, utilizing open-weight vision models to extract metadata from PDFs and photos without cloud platforms. It features a Python backend and SQLite database for CSV or JSON exports. Simultaneously, CyberTools Hub AI is being developed for the Hacktoberfest 2026 Open-Source AI Challenge. This project leverages open-weight AI models to simplify security log analysis for beginners and small IT teams during technical troubleshooting.
