Scanning a long document for every mention of a specific word or pattern is tedious using Ctrl+F alone, especially when you want to see all matches at once rather than clicking through one at a time, and this highlight text tool solves that by visually marking every occurrence instantly. It supports both plain substring search and full regular expression matching, making it useful for editors checking word usage across a manuscript, developers searching logs for a pattern, and researchers scanning documents for keyword mentions. Paste your text, enter a search term or regex pattern, and every match gets highlighted in place along with a total occurrence count. Since the search runs entirely in your browser, your document is never uploaded. Paste your text below and start searching instantly.

Frequently asked questions
How is this different from a browser's built-in Ctrl+F search?
This tool highlights every match simultaneously and shows a total count, while Ctrl+F typically cycles through matches one at a time without a persistent highlighted view.
Can I search using a regular expression instead of plain text?
Yes, the tool supports full regex pattern matching, so you can search for patterns like email addresses, phone numbers, or custom formats, not just literal text.
Does the search support case-insensitive matching?
Yes, you can toggle between case-sensitive and case-insensitive search depending on whether case matters for your search.
Is there a limit to how long a document I can search?
No practical limit, since searching and highlighting run locally in your browser rather than through a server request.
Can I use this tool to count how many times a word appears?
Yes, it displays the total number of matches found alongside the highlighted occurrences in the text.
Is my document uploaded anywhere when I search it?
No, all searching and highlighting happens client-side in JavaScript, and your text is never sent to a server.
