Some of these are a bit dodgy. I tried sudowrite and chibi ai. Sudowrite promises certain amount of free words - but takes you straight to a message that says 'you have used all your free words'. Chibi gives you 2000 free words to start but well before the 2000 words another message saying you have used your free words. appears. There is 'click to get chibi app' which takes you to twitter and no app. Does not engender confidence in the products. bi
