PerceptaHeal is a local-first, AI-assisted multilingual UI quality auditor and CSS repair-preview tool. It uses Playwright to inspect local websites across different screen sizes and detect issues such as text clipping, horizontal overflow and overlapping controls. It integrates Meta's Llama 3.2 3B model locally through Ollama to generate CSS repair suggestions. A strict safety validator checks the generated CSS before applying it to a temporary browser preview. PerceptaHeal then runs another audit to verify whether the measured issues have improved. It also provides review notes for visual cases such as gradient and image contrast that cannot be reliably measured by its current DOM-based checks. The original website files are never modified.
