I tried it out on a ten chapter story and the first few chapters came out empty except for the title and the word "settings". I agree with another reviewer that the pages really aught to be downloaded and converted locally, there's no good reason for it to send them out to a cloud server, and I suspect that's how I got broken chapters because they just didn't load properly on the cloud server (the broken pages were from the same site with the exact same formatting as the ones that worked). I tried again and the download button just won't even work now. Great idea in theory, I just wish it worked.

On Firefox: opens the settings, then works for a while then stops saying "Done !", but no download, nothing.
From then on, even with a new set of tabs and after closing and reopening the browser, never offer settings again. Just says "Done !". So am I...

Didn't work; just created an epub of legal jargon.

Liked the idea of the multiple tabs and being able to re-order them.

Needs more options to be able to add 'author', 'website' (for ability to link to again from ebook reader when it's months or years later), 'publisher', 'tags', etc.

Love the idea and was excited to try it. It lets me select the tabs to save in the book and then I click download. It appears to be working for a few moments and then I get an error message "Failed Sever Error." Every single time.
