I recently dug up some old family photos and wanted to keep them on my phone, but photographing them directly turned out blurry.
Luckily we live in the age of AI. Just tell ChatGPT: "increase the clarity" and it will repair and colorize the photo for you.
Free accounts can process three images per day — if you don't want to pay, simply register a few extra accounts to handle more pictures. The prompt itself is universal and works with other image-capable AIs too, but in my experience ChatGPT gives the best results.
