You could also just let people choose the languages and offer a few interesting presets, like the english - hebrew - arabic you currently do.
Would be nice to offer an extreme example you found on the landing page as well, as it might be a bit empty and would attract more people.
Also maybe global stats for each language the percentage of text that is contradiction, percentage that is only in that version, percentage that is different framing. So people can then order them and compare percentages and stuff. Could be cool
