Overview
Image Upscaler 4K is a dual-engine AI image upscaling platform that lets you enlarge images to 4K resolution in seconds. It offers a fast mode (Recraft Crisp) for quick 4x enlargement in 3 seconds, and a pro mode with five specialized Topaz AI models for portraits, product photos, old prints, documents, and AI-generated art. Users can adjust sharpness, noise reduction, and face enhancement. It's designed for e-commerce sellers, photographers, digital artists, real estate agents, and graphic designers.
Taste Lab is an open-source tool that reverse-engineers the design taste of any website. It uses four specialized AI agents to extract precise design measurements (colors, typography, spacing, radius, shadows), detect systematic patterns, infer taste principles (with reasoning and trade-offs), and output a final design context. The output is two files: a .md and .json containing a Design Map and Taste DNA. It integrates with popular AI coding tools like Cursor, Windsurf, Claude Code, and GitHub Copilot.
