[Haskell-cafe] Interactive chatbot

My students have the task to program an interactive chatbot. We have
run into a problem that I can't solve either:
When we read the user's input through
> t <- getLine
it is not possible to delete typos before hitting enter and thereby
sending the input off to the system (at least in OS X, bash). I didn't
find that terribly problematic, but of course it is a bit of a show
stopper from their point of view.
The input is then used to generate a reply in purely functional code,
and the reply sent to the command line via putStr. Is there a more
clever way to interact with the user that would allow editing ones
text before sending it to the bot?
I guess we could try with a website, but don't know off hand how to do
that, either, although I've seen beautiful webservers made in Haskell...
