GTools

A growing collection of small utilities I've built to solve problems I kept hitting. Each one is open source, single-purpose, and (usually) takes only minutes to install.

beta

A transparent inspector and rule engine that sits between your AI clients and their upstreams — logs every request, threads them into conversations, and applies rules that fix model behaviour on the way through.

BinaryExplorer

beta

A WinUI 3 desktop app for inspecting Windows binaries (.exe / .dll / .sys / .winmd / .msi) without running them — language detection, signatures, hashes, imports, capabilities, ETW providers, strings/IOCs, packing, resources, disassembly, decompilation, and embedded files.

DriveVisualizer

stable

A fast, WinDirStat-style disk usage analyzer for Windows (WinUI 3 + Win2D) — scans a drive in parallel, draws it as a treemap, sunburst, or icicle, and lets you clean up straight from the map.

PixelPet

alpha

A customizable 8-bit pixel-art desktop pet for Windows — a little cat that lives on your desktop, sits on top of your windows, wanders around, naps, and reacts when you hover, click, or drag it.

ProcMonClone

experimental

A Process Monitor–style activity monitor built on kernel ETW (and the Procmon minifilter) — a learning project that captures live process, file, registry, and network events across the machine.

Simple Event Viewer

A modern WinUI 3 replacement for the Windows Event Viewer — fast streaming reads, cross-aware filters, EVTX file support, and an optional MCP server so an LLM can query your logs.

Simple PCap Viewer

beta

A WinUI 3 viewer for pcap/pcapng capture files that's easy to search — and, primarily, exposes packet captures to an MCP server so an AI assistant can search and analyze network traffic for you.
