Replace every occurrence of a word or phrase across a large block of text in one click.
Manually replacing every instance of a word across a long document — a name that changed, a product that got rebranded, a repeated typo — is a task that scales badly by hand. Miss one instance and it's easy to overlook, especially in a document longer than a page or two. A find-and-replace tool exists precisely to make this operation reliable regardless of document length.
This tool scans your entire input for every occurrence of the text in the "Find" field and swaps each one for the text in the "Replace with" field, reporting exactly how many replacements it made so you can confirm the change matches your expectation. The optional case-sensitive toggle controls whether "Apple" and "apple" are treated as the same target — leave it unchecked for a broader replacement that catches every capitalization variant, or check it when you need precision, such as only replacing a capitalized brand name and not the common noun.
It's a staple for writers doing a global correction across a manuscript, developers cleaning up copy-pasted text or config values, students correcting a repeated mistake across an assignment, and anyone editing a document where a term, name, or phrase needs to change everywhere at once. Everything runs locally, so the tool is safe to use even on drafts or documents you haven't shared with anyone yet.
