A lightweight Windows utility that records system audio directly from the sound card. I built it to record meetings and online courses without artificial noise. Developed with AI + Codex as a coding partner. Supports MP3 export (requires libmp3lame.dll). Download from GitHub releases.

PDF Tools is a lightweight desktop application for handling PDF files locally. Most online PDF tools have file size limits or require uploading sensitive documents. This tool runs completely offline, so your files never leave your computer. It supports common PDF operations such as merging, splitting, compressing, and converting PDFs, and works well even with large files (200MB+). Built for people who care about privacy, reliability, and simplicity.
