Have you ever seen jagged text on anything other than PC and old game consoles ?
Is it normal for characters to be jagged when viewed on a PC? With the evolution of display performance, the days when PC characters had to be rough dots are long gone. Despite this, the characters on typical browsers still look like those on retro game consoles. With the arrival of Sleipnir, you can finally browse the web with beautiful, modern characters on your PC.
The beauty of a professional graphic tool is a given with Sleipnir.
To maximize the beauty and readability of characters, Sleipnir uses a uniquely adjusted font rendering. The difference is immediately noticeable, and the display is on par with professional graphic tools. Being able to browse the web with beautiful, easy-to-read characters is a luxury on a PC, but with Sleipnir it's a given.
Compare it to your old browser now
You'll see how easy it is to read plain text now - there's no reason to go back to the jagged, outdated look of text.
Find tabs easily even if you have 100 open
Compared to when web browsers first got tabs, it is now common to have more and more pages open at the same time, including web apps and social networks. Sleipnir has been carefully designed down to the last detail so that you can quickly find the page you want to see. Even if you have 100 tabs open, or even none at all, you can quickly find the page you are looking for. Let's take a look at some of the many ingenious ideas.
