When you need to find specific patterns in large text — log files, code dumps, data exports or documents — scrolling manually is impractical. This tool keeps only the lines that contain your word or match your regular expression, with the number of matching lines and optional context lines around each one. Think of it as a browser-based grep that requires zero setup and works on any device.
Searching through application logs for error codes or stack traces. Finding all occurrences of a variable, function, or string in code snippets. Locating specific entries in large CSV or JSON data dumps. Checking if a document contains specific keywords or phrases. Counting occurrences of patterns in research data or text corpora. Quick lookups when you don't have access to command-line tools like grep.
Plain text or full JavaScript regex search, case-sensitive or not. Matching or non-matching lines (like grep -v), with 0 to 10 context lines (like grep -C). Windows (CRLF) and Unix line endings are both handled. A pattern that would backtrack forever is stopped instead of freezing the page. Copy the result or download it as a .txt file. Runs entirely in your browser — nothing is uploaded or stored.
