Text Frequency Filter

Filter log lines by how often words appear

When you paste server logs or chat transcripts, noisy rare tokens and repeated error keywords behave differently. This tool counts word frequencies across the entire input, then keeps only lines where at least one word (or every word, your choice) falls inside a minimum and maximum frequency band.

Example workflow

1. Paste multi-line text such as application logs.
2. Set minimum frequency to 2 to focus on words that repeat.
3. Choose any word matches to keep lines that mention a hot keyword.
4. Copy the filtered lines into a ticket or spreadsheet.

For character and word totals without filtering, open Character Word Counter. To compare two versions of a file, use File Diff.
