Grab Text

A Go CLI tool that downloads YouTube subtitles, converts VTT to plain text, and summarizes the content using a local GGUF language model. Uses CGo bindings to call llama.cpp directly for on-device inference — no cloud APIs, no network requests for AI. Replaces a prior shell script + Python + opencode pipeline with a single compiled binary.
