are you creating these from programs you intend to write?
here is a 7 day trial (they said free) utility to create flow charts. there are a lot out there and if you search you might find a total free one. but to be honest you can easily create these yourself using any number of graphic editing programs.
pseudocode as i know it doesn't really have any definite structure. it's in your own words, but sort of code orientated.
