A repeated spelling or label can be changed quickly with a global replacement, but a short search phrase may also occur inside longer words. ERITHRA’s Find and Replace Text searches for literal text throughout the input. Checking the result and replacement count is part of the operation, not an optional finishing step.
Enter a precise search
Paste the source, fill Find this literal text, and enter Replace with. Leaving the replacement blank removes each match. The search field must contain a value; an empty search is rejected rather than inserting text everywhere.
Leave Ignore case unchecked when capitalization matters. Enable it when uppercase and lowercase versions should all match. The replacement is inserted exactly as entered, so it does not automatically preserve the capitalization of each original match.
Select Process text and inspect Replacements alongside the output. All matches are handled, rather than only the first. There is no whole-word checkbox, regular-expression mode, or preview selection for individual occurrences, so choose a search string specific enough for your actual text.
Trace a substring example
Enter red, redwood, Red as the source, red as the search, and blue as the replacement. With Ignore case off, the result is blue, bluewood, Red, and the replacement count is two. The match inside redwood is intentional under literal substring rules.
Enable Ignore case and process the original again. The output becomes blue, bluewood, blue, with three replacements. The final Red becomes lowercase blue because that is the exact replacement you supplied.
Punctuation in the search is treated literally. Searching for a period looks for an actual period, rather than using the regular-expression meaning of “any character.” Replacement strings are also used literally: a dollar-sign sequence is not a special capture-group instruction in this tool.
Verify wording in context
For an organization name or a technical term, use a sufficiently complete phrase and inspect every affected sentence. A replacement can be mechanically correct while making grammar awkward or changing an unrelated identifier. Copy the source elsewhere before making a large revision.
Processing happens in your browser and produces a new text result; it does not update a document in another application. Preserve intentional spaces if they are part of your search. Use Text Difference Checker to inspect changed lines against the original. If the issue is a broad capitalization style rather than one known phrase, Case Converter provides explicit sentence, title, upper, and lower case transformations.
