CodeDuet — Demo video

This project solves the problem of needing an always-available pair-programming partner by giving you a real-time voice assistant for coding challenges. It supports both autonomous execution (bot_drives) and coaching mode (human_drives), with struggle detection that triggers targeted hints when you stall, repeat failures, or ask for help. It also solves progress tracking by combining sandboxed test runs, level-based challenge progression, and a Notion session log of what happened and why.
