How does the diff algorithm work?

It's a classic LCS (longest common subsequence) diff that operates on lines. Identical lines stay put; added lines are flagged with +; removed lines are flagged with -.

Can I use this for large documents?

Yes, but the LCS algorithm is O(mn) in memory and time. For documents under ~5,000 lines per side it runs in milliseconds. Above that, expect some delay.

Is this like git diff?

The output is similar in spirit — same unified format (+ / -) and same line-level granularity. The algorithm is simpler (no heuristic context trimming, no --color-words mode).

Is my content uploaded?

No. Both documents are processed entirely in your browser. Neither is ever sent to a server.
