Current coding assistants ignore the developer's mental state. A tool that detects focus levels and mood could suggest different types of help.
Build an IDE plugin that uses typing patterns, camera input (optional), or wearables to gauge developer state. Offer calming suggestions when frustrated or complex ones when focused.
Individual developers and teams would pay for improved productivity and reduced burnout.
MVP could just use typing speed and pauses as input. Add more sensors later.
Risk is accurately detecting states without being intrusive.
