Problems it fixes
Good at
- Free, with no account for the desktop app
- Photos stay on your computer
- Runs on Windows 10+, macOS 12+ and Linux
Watch out
- Needs a Vulkan-compatible graphics card; many built-in (integrated) GPUs do not work
- Like every upscaler, it can invent detail that was never in the photo
