I use adobe lightroom. It has an enhanced algorithm that really does a very good job at upscaling images. You might also try https://imglarger.com/. Source: over 1 year ago

But this time I just googled and ended up with https://imglarger.com/ that did the job well. Source: almost 2 years ago

I don't, but try imglarger.com, it's A.I. That scales up an image, I always get amazing results. Source: almost 2 years ago

Hey, this picture looks so cooool!! I save your original image and upload it to imglarger.com to sharpen it. Here is the result. I am not sure if it is what you want. But I think the the color and contrast is better after the image is sharpened by imglarger. Source: about 2 years ago

Image was upscaled with imglarger.com as Dall.E's output images are way too small. Source: about 2 years ago

Rhasspy seems promising and I started to tinker with it, but didn't get to a functional state before I got distracted by something else. Source: 7 months ago

There's many voice control options for HA, both private ones like Rhasspy and the corporate spyware ones that only an idiot would use. Source: over 1 year ago

Rhasspy is amazing and more capable than Mycroft (e.g. Satellite support, something that’s mandatory imo), but even more DIY and beginner-unfriendly. That said, the docs are decent, the community is helpful. Source: over 1 year ago
