Langchats alternatives

amazing it is a very nice tool to use for a practise in everything i know whatever it does you can do it with chatgpt or anything else but for some reason that looks what i was looking for trained for an interview and also joked with it and it kept the "professional tone" all the way the only i want it to to is add more languages like dutch and greek and do not give that much of an "error" messages for . "blanks" and capital at the beginning and focus more in gramatic and the sentence suggestion like rephrased words keep at it!!
