I don't think the previous comment was trying to be snarky - I can see where they're coming from.
Take my feedback with a grain of salt, as I am entirely not the target audience, but...
"Stay Connected, Always" - weird way to put it, given it's for offline situations. At this stage it sounds like it could be a 4G or portable wifi solution?
"Use our apps for offline content or the Kiwix Hotspot for reliable access." - so it's probably a desktop or mobile app, maybe a web app. What is Kiwix Hotspot, another app? Unclear there is a hardware at this point, or any on the home page unless I watch the video that hints at it.
The summary in the footer was a lot clearer to me: "Kiwix is an offline reader for online content like Wikipedia, Project Gutenberg, or TED Talks. It makes knowledge available to people with no or limited internet access"
Again, not trying to complain for the sake of it, I think this is a cool project helping under-served communities, but if people can't easily understand what you do, they may not dig deeper.
If I can't tell what is being offered without much thinking or digging, the home page isn't doing as much as it could be.
Perhaps it is ticking the boxes for your target audience if you have done some testing. Great! If not, some quick user testing could help optimise the messaging to make sure what you offer is landing.
