Text Tools Guide

Developers process text constantly — comparing config files, cleaning log data, sorting lists, counting characters for API limits. The right tool turns a 10-minute manual task into 10 seconds.

Text Diff

Uses the Myers diff algorithm to find the minimum set of changes between two inputs. Essential for comparing API responses, config files, or log outputs — without needing a full IDE.
