Translate chatc99.chat can translate the comments in this chat automatically (paid feature, see ): Each comment will be translated into a language defined by you. Each participant in this chat can define his own target language.
You can add additional features here.These are paid features. The feature will be available for this chat. Payment is processed via an external payment provider (Stripe); no payment data is passed through c99.chat.
Automatic translation
Unencrypted chats will be translated automatically.
More informationThis is a paid feature. You will enable automatic translation for this chat (for every participant). Translation uses a Google Cloud service, so the chat entries will be sent to a Google server. Therefore automatic translation only works for unencrypted chats, not for surveys and only up to a certain number of characters (30.000 - this corresponds to the text amount of a small novel). The chat participants can choose their own target language, but note that translation counts for each target language. Supported languages are English, Arabic, Chinese,French, German, Indonesian, Italian, Japanese, Polish, Portuguese, Russian, Spanish, Ukrainian.

If you share this link via email, WhatsApp, SMS etc, you won't stay anonymous:
Configure here if your browser shall send you a notification in case of new activities in ANY of your active chats.
As long as your browser is open (even when in background), it will inform you.
You have to be away from this browser tab for 30 seconds or longer.
Upon first configuration your browser will ask for your permission.
This does not work (yet) on Apple iOS devices, or on anonymous (private) browsers.
Note that within a chat, you can also set chat-specific email notifications.
Play sound on new messageMore info
When you have an (ANY) open chat, each new comment will trigger a short notification sound. Use this for example when a chat is running on an unattended device. Note that comments will not be updated automatically when the chat window is not active (i.e. not in the foreground of the browser). Careful, this does not work on iPhones and some browsers, as these prohibit playing a sound without user interaction. Additionally the screen will flash briefly when a new comment arrives.
These email notifications are valid for this chat only. Use the notification icon at the top right for generic notifications.
Enter your email address here. You will receive a confirmation email from c99.chat, in which you have to click a link. Please also check your Spam-folder for this email in case you don't see it.
In the default setting ( set to 'Off') you will receive (exactly) one email for the first new comment in this chat which was created 30 seconds or more after you last read the chat. You will not receive further emails (also not if new comments are posted) until you have entered this chat in the browser.
If you set the icon to 'On', you will receive an email for each chat entry.
These notifications apply only to 'active' chats. Archived chats do not trigger a notification.
In the notification email you can unsubscribe again.
Your email address will not be disclosed to others, especially not to anyone else in the chat.
You can switch on/off notifications here, while your email address remains confirmed.
We have some games which you can play with your chat partners.
Connect4! There will be an entry in the chat for two players - allocation is random. Click on the respective player names. This game is based on code of Juan Bouquet.
Chess There will be an entry in the chat. The allocation of white/black is random. Click on 'New game' to start afresh, or click on the status button to continue an existing game. The board will refresh after each move; please take care whose turn it is! Only one chess game is possible in one chat. You can lock the 'scrolling' of the underlying page with the switch on the chessboard in case it disturbs you. This game is based on code of Greg Wilson; see also here.
