NEM
NEM is a desktop AI assistant I am developing to help users decide what to work on next. Its priority assistant considers urgency, importance, deadlines, and overdue tasks to organise a task list and recommend the next action. Users can add tasks through natural language or voice, using terms such as “urgent,” “important,” or “later.” When timing is unclear, NEM asks for clarification and provides reminders to help users stay on track.
