Overview
Image3D AI is an online AI-powered tool that transforms 2D images into 3D models and STL files, catering to 3D printing, game development, e-commerce, and architecture. It integrates multiple AI engines, supports single-image and multi-view modes, and generates low-poly models with optional PBR materials. Users can preview results instantly and export in STL, OBJ, and GLB formats. The platform offers free sample images for testing without login.
Very Good Calendar Sync is a native macOS app that runs in the menu bar, synchronizing events between different calendars (Google, Microsoft, Apple, CalDAV) without linking accounts or exposing sensitive data. It allows users to clone events with full details or redact them to show only busy status, ensuring privacy. The app works directly with Calendar.app, requires no extra setup, and runs entirely on the Mac with no servers or data collection.
