Additional information
How to use the acrostic extractor
An acrostic often hides a word or sentence in the first letters of a text. This tool also lets you test last letters or a precise position, which is useful for puzzles and treasure hunts.
Lines
Line mode analyzes each non-empty line. It is ideal for a poem, a clue list, or a message deliberately written across multiple lines.
Words
Word mode analyzes words separately. Use it to check whether initials or last letters in a sentence form a hidden message.
Nth letter
The maximum position automatically follows the longest line or word. If an item is too short, no letter is extracted for that item.
Example
With the lines Ancient, Mystery, and Old, 1st letter of each line gives AMO. For broader extraction by sequence, pattern, or mask, also use the letter extractor.
