Additional information

How to use the difference message tool

This tool compares two very similar texts to reveal a hidden message. It is useful when a clue is hidden in added, removed, replaced, accented or uppercase letters.

Two close texts

Paste one version in Text A and the other in Text B. The closer the texts are, the easier the useful differences are to read.

Usable modes

Modes that return nothing are disabled automatically, so you only try the readings that can produce an output.

Puzzles and variants

Try several modes: some messages are hidden in additions, others in case changes, accents or symbols.

What do the modes mean?

Mode	Reading	When to try it
A	Letters added in text B.	When the second text seems to contain extra characters.
B	Letters removed from text A.	When the first text looks more complete than the second.
C	All differences in comparison order.	For a first global reading.
D	Position differences, text B side.	When both texts have similar length and some letters change.
E	Position differences, text A side.	To read the same difference the other way around.
F	Replaced characters from text B only.	When one letter has been substituted for another.
G	Replaced characters from text A only.	To recover the original letters of substitutions.
H	Case differences from text B.	When uppercase or lowercase letters look suspicious.
I	Case differences from text A.	To read case variations from the other text.
J	Accent differences from text B.	When accented letters seem intentional.
K	Accent differences from text A.	To compare accents the other way around.
L	Modified or added symbols.	When punctuation or symbols seem to carry the clue.
