Reply to a message when you understand roughly what someone wrote but writing back in their language is the hard part. It happens all the time if you live abroad: the landlord asks when you can let the plumber in, your kid's school wants a form back by Friday, a buyer on Facebook Marketplace asks if the bike is still available, a client writes in German. Paste their message and get an answer you can send.
You can tell it what you want to say in any language, in a few words: “yes, but Thursday doesn't work for me”, “ask for the deposit back”, “say no politely”. If you leave that blank, you get a short, friendly reply that acknowledges the message and says you'll check and get back to them, or asks one simple question.
Next to the reply you get its translation into the language of this page. That way you never send something you can't read. The reply is kept about as short as the message you received and matches its tone: a chat stays casual, a business email stays formal.
By default the reply is written in the language of the message you received. If you want it in another language, pick one of 45. That helps when someone writes in English but you know they would rather read Spanish, or the other way around.
It doesn't invent facts. It won't say you have paid, signed, agreed or are free on a certain day unless you tell it to, and it won't make up dates or prices. Still, read the reply before you send it: AI writes it, and you know the situation better than it does.
The message is processed on our server and is not stored there. A normal message takes a few seconds. The reply and its translation are saved in the library in your browser, and from there you can make the reply more polite, shorter or more formal.
