About

PrompTessor is a web-based SaaS platform that transforms AI prompt optimization through an intelligent analysis engine delivering deep insights, detailed metrics, and actionable optimization strategies. Users submit their prompts to receive a comprehensive effectiveness score, often on a 0–100 scale, that highlights strengths and areas for improvement across core dimensions such as clarity, specificity, context, goal orientation, structure, and constraints. The system offers granular feedback with visualization of performance metrics over time, continuous progress tracking, and side-by-side comparisons of optimized prompt variations generated to enhance AI performance. An intuitive interface guides both beginners and experts through prompt refinement: interactive dashboards display heatmaps of prompt components, while automated recommendations suggest rephrasing, restructuring, or adding context to maximize output quality.
