I built SilentGPT as a fully terminal-based ChatGPT client written in C.

Why? I needed something minimal that respects my privacy and runs anywhere — even airgapped or offline shells.

Features: - Written in C, single portable binary - AES-256-GCM encryption for chat history and API keys - Supports multiple tokens via `--token` - Optional password protection via `--secure` - No OpenAI logging – pure curl + OpenSSL - Export, list, delete, rename chats — all from CLI

This is my first real C tool at this scale — happy to hear your feedback or critiques.

Silent and precise.
