Show HN: PoseUp – Turn Casual Portraits into Shots with AI (Free, No Signup) (poseup.ai)

Hi HN,

I built PoseUp – an AI tool that instantly enhances casual selfies or people photos into professional-quality images.

How it works:

Upload a selfie, portrait, or group photo

Our AI improves lighting, composition, colors, and overall quality

Optional: 4K upscaling, smart resizing, layout export (like 3x3 grids)

The goal: Help people get “magazine-style” photos from everyday snapshots — no editing skills or prompts required.

100% free, no login needed https://poseup.ai

Would love feedback — especially around photo quality and UX. Thanks!
