Free! SLICK WRITE provides instant feedback on style, structure, and flow for any collection of text(s) up to 200,000 characters. The interface could use a makeover, but the feedback is helpful. We especially got a kick out of this warning not to use wordy or redundant phrases: "Think of Donald Rumsfeld. Do you want to sound like him? Of course you don't." To get started, copy and paste your text into the textbox under the 'Edit' tab (2nd from right) and click the 'Proofread' tab. Next click through the remaining tabs to view analyses for flow, structure, and grammar usage. Re-write if you fancy!
