What the tool does, how to run it, and what to expect from the result.
ROT13 rotates each letter 13 places: A becomes N, N becomes A. Because 13 is half of 26, applying it twice gives back the original, so one operation does both jobs. It hides spoilers, puzzle answers and punchlines from a casual glance; it is not encryption.

The alphabet has 26 letters, so two shifts of 13 add up to a full turn and land every letter back where it started.
No. It is a fixed Caesar shift anyone can reverse in a second. It is for hiding text from accidental reading, not from anyone trying.
