Find and Replace

Search a document for a word or pattern and replace every occurrence at once. Toggle case sensitivity, match whole words only, or switch to regular expressions with capture-group substitution ($1, $2) — the live match count tells you exactly how many replacements will happen before you commit.

Frequently Asked Questions

Does it replace one by one?

No — every match is replaced in a single pass, and the live count shows how many that will be.

What do regular expressions enable?

Pattern search and capture groups: find (\d+) and replace with n$1 rewrites every number in one run.

Is searching case-sensitive?

By default it is not; switch on the case-sensitive option when capitalization matters.
