Comparing two sources

Comparison works on study projects you already have. Build one from a Wikipedia topic, a web page, an uploaded document, a paper or a video, then build a second from a different source, and bring the two together.

Both projects stay on your device. Nothing is uploaded to compare them, and neither project is changed by comparing it.

It compares the words two sources use. Where two sentences share enough of their content words, they are shown side by side with the words that caused the pairing.

That is a real signal and a limited one. It cannot tell you that two sources agree, because agreement is about meaning. It cannot tell you they contradict each other either. What it gives you is a pair worth reading yourself.

Points that cover the same ground are the pairs. Everything else is listed under the source it came from.

A sentence appearing under only one source does not mean the other source omits the point or disagrees with it. It means no sentence in the other source shared enough words to be paired, and the same idea may well be there in different language.

Every sentence shown is quoted from one of the two sources exactly as it stands. Nothing is summarised, paraphrased or generated, which is the same rule the rest of the site follows.
