What Our Happy Customers Say

Emma Richardson
As a social media creator, I generate a lot of visuals with Nano Banana, especially for IG posts. Sometimes the original resolution isn’t sharp enough, so I usually enhance the images with Artguru on my phone before posting. No ads, just quick resolution upgrade. It’s so convenient.

Sophia L. Travel Vlogger
I‘ve been using Artguru for about 6 months. I generate a lot of concept art with Nano Banana and sometimes turn those pieces into prints for clients or small events. The original files looked fine but theyt wasn’t sharp enough for printing posters. Artguru helped me upscale to 4K without changing the colors or overall style. It helps me a lot.

Kevin Thompson
I work on game projects and will use images for demos and presentations. What I appreciate Artguru is that it keeps the details clean without oversharpening. The higher resolution option is useful when I need assets for large screens. I’ve recommended it to my teammates!
