Mona, tellme - AI-assisted analysis 🧠

With mona v3, debugger automation took a major leap forward. Now, with the new tellme / ai command, mona can collect crash context, heap information, registers, call stacks, disassembly, memory mappings, PoC files, heapdynamics logs, and more — and turn all of it into structured AI-ready analysis requests.

This article dives deep into how it works, how to customize it, and how to build repeatable, reusable AI-assisted exploit analysis workflows on modern Windows targets. Read more
