Keyword frequency

A long time ago, in land far far away my friend and, at the time, colleague, Matt created a little flash tool to split text or list of keyphrases into individual keywords.

I needed a little keyphrase something that did the same thing, but more hackable and much faster. In hindsight JavaScript was an odd choice, but it seems to work okay, even on stupid inputs.

Paste your input in the box on the left. Press the button. Done.

Keywords, sorted by frequency are comma-delimited, making the output suitable for saving as a .csv and opening in a spreadsheet.

Notes:

If you're planning on using serious (10,000+ words) volumes of data you will probably want to disable the Firefox form spellcheck feature - simply right-click both of the above fields and uncheck the 'Check Spelling' option.

Your data is safe. All the calculations are performed in JavaScript in your browser, nothing is communicated back to me or anywhere else (other than an indication that you've been on the page)
