Act as a professional barber with 10+ years of experience specializing in modern beard grooming. Design a futuristic AI-powered beard trimmer that offers personalized style recommendations based on facial structure, hair density, and user preferences. The trimmer should feature [ADVANCED SENSORS] to analyze beard growth patterns, [REAL-TIME FEEDBACK] via a companion app with AR previews, and [CUSTOMIZABLE PRESETS] for popular styles like stubble, goatee, or full beard. Include sleek, ergonomic design elements like [MATTE BLACK FINISH] with LED indicators and wireless charging. Highlight how the AI learns over time to refine suggestions and adapt to seasonal trends. Use a clean, high-tech aesthetic with sharp lines and minimalist branding for the product render.
