Using Tbot – the Messenger Bot powered by Microsoft Translator


Tbot is an automated buddy that provides translations for Windows Live Messenger. It was first launched in 2008 as a prototype pre-dating many other bots and has since become immensely popular. You can have one-on-one conversations with Tbot or invite friends (group conversation) who speak different languages with Tbot translating for you.

Following is a set of frequently asked questions about the bot. If you have any technical questions, please post them in our user forums.

[Q1] How to install/add Tbot in your Messenger?

1. Open your Live Messenger and look for the Add a contact or group icon.


2. Type in as your contact.  Tbot will now show up as one of your contacts.


[Q2] How to use Tbot commands?

1. Type TBot ? to see all the Tbot commands.  You will see the following list of Tbot commands.


2.  To see your current translation language setting, type TBot lang. For instance, if you were translating from French to English in your previous session, you will see the following.


(If you're going to use Tbot for the first time, this is not applicable.)

3. To change your translation language setting, type TBot change.  Tbot will first show you the list of source languages (FROM languages) as shown below.

You have to select your source language here!!  Otherwise, Tbot won't understand any commands.  In other words, commands such as Tbot ?, Tbot lang, etc. won't work until you select your source language.


4. Once you select your source language, Tbot will ask you to select your target language (TO language).  Please select your target language.  Again, if you don't select your target language here, Tbot won't let you move on.  In other words, commands such as Tbot ?, Tbot set, etc. won't work until you select your target language.


5. Once the source and the target languages got selected, you're ready to translate.  Start typing any sentences.

Here is a snapshot for TBot translating from English to Japanese.


6.  Now if you want to change your language pairs, you can just type TBot change, and do #3 and #4 above.

     If you want to list all the TBot commands, you can type TBot ? 

7. How to use TBot set

One of the TBot commands is TBot set.  Please note that this is to set up the language for your user interface, not for your translation language(s). 

For instance, when you type TBot set, you'll see the language list as shown below.


If you are a Korean and want to see TBot's instructions in Korean, you select Korean, so that you can see TBot's instructions in Korean as shown below.

[Q3] How to talk to someone with Tbot's help?

Here is an example of how Takako who speaks Japanese is able to talk to Erik, who speaks Portuguese.

(1)   Takako invites Erik, and then invites Tbot.  You’ll see both Erik and Tbot on your conversation pane as shown below.


(2) Takako set the language pair using the Tbot command, “Tbot change”.

She set the source language to Japanese and the target language to Portuguese.



(3)   Takako and Erik can start the conversation using Japanese and Portuguese, respectively.

For instance:



That's it!

    Thanks. What would be VERY useful: how exactly can a conversation between 2 persons speaking different languages be translated? I mean, which steps have exactly to be taken to make the tbot translate between them? Who has to speak to tbot 1st and iniate the translation commands? If there's any tutorial on this, would be mighty happy about this. Again thanks, in advance. Regs, Rob

  2. Grodan says:

    I has problems adding tbot to a group. Is it posible?

  3. Musa turky says:

    Hi. I was looking for another  langauge to translate. the langauge is Argentin. it is possible from Tbot to   translate?

    thanks alot

  4. Hello Musa,

    the major language of Argentina is Spanish. You can use TBot to translate from and to Spanish.

  5. Hello Rob,

    You would add Tbot in your contact list. When you start a conversation with one of your contact, you would invite Tbot as well. It is as you are having a 3 way conversation with 2 friends. Whatever you type in your message, Tbot will translate it so that your friend can see the translation. What I would suggest is that if you were the person who initiate a conversation, invite Tbot and your other friend(s) and vice versa. Hope this helps.

  6. Hello Grodan,

    After you add TBot as your contact, when you open Windows Live Messenger, locate Tbot from your contact list. You should then be able to drag and drop it to any of your existing groups.

    Does TBot work across IM types?  I am using LCS 2005 and it doesn't seem to play well with MSN, so i just thought i'd check.

  11. Hi Rob,

    The three-way conversation (2 persons + Tbot) is explained at

    Look for the section called "How to talk to your friend using Tbot?". Hope that this is helpful.

  12. Hi cbaker0220,

    Tbot doesn't work 100% with LCS; 1:1 session with Tbot seems to work but multiple session (i.e., inviting another contact) doesn't work.  Hope that this helps.

    How do you fix it?

  15. a person says:

  16. Jim says:

    The bot went down yesterday and has not been working for me since then!  Whats up??

  17. Tbot is now back online.  Please try it again!

  18. Robbie says:

    is Tbot down? does this happen a lot?

  19. MSR-MT Team says:

    We were rolling out a update to Tbot, which inadvertently brought it down.  It should be functioning again.  Please try now.

  20. says:

    So, in the meantime I got some help by the Buddies. It works that way: you initiate a chat or get invited to one, then you invite the Tbot in addition. Separately or before you configured your language pair as needed, e.g. English – Spanish. When invited Tbot now recognizes you and the language pair you configured before. You start activating Tbot by greeting him (e.g. Hello), from this point of time on he will translate for you. And the point is: he automatically translates for the other person too, but in different direction (in that case Spanish – English). That way the whole conversation can happen without any limit. Thanks to all of you wanting to help, maybe this info is useful for you too 🙂

  21. Mike says:

    How can I keep TBot active after I have not typed anything for awhile? I have MSN Messenger on my 4G iphone and I do not know how to invite contacts  using TBot, can anybody help me?

  22. Hello Mike,

    Unfortunately, there is no "keep alive" feature for Tbot.  After a period of inactivity, Tbot itself will go inactive.  However, it should become active again if you ping it with a simple "Hello".

    In response to your second question, tbot is designed to support group conversations.  The gating factor is which messenger client you are using.  I suspect you may be using the IPhone WL messenger, which does not support group chats, so tbot will not work in that context.  We're in contact with the messenger team to have this problem resolved.

  25. Randall says:

    How do I connect the BOT with the person I want to translate with. I want to set up between myself(english) and a friend(spanish) what do I do?? to get translating ??  When do I bring Bot in?? After myself and contact are connected  ???

  26. Hi Randall,

    you invite the person you want to talk with and TBot into the same conversation. TBot will translate everything either of you says in the conversation. You can also invite additional people into the conversation.

    thank you so much

  28. says:

    All these instructions seem so simple but when I'm attempting to use the bot with my foreign friends I can never get it to work. My friends always have to initiate the mtbot. I have no idea why it will not work for even after I follow the detailed instructions.

  29. Hello Tweetalig,

    It would be helpful if you can specify where/at which stage you usually get stuck.  That way, we can provide you more specific instructions.  Thank you.  Takako (Translator Team)

  32. Hi mfmd,

    Pardon my pre-long weekend foggy mind. To use the Tbot,  please simply add to your Messenger contacts. If you go to, there is a short intro about the Tbot.

  33. Hi Will,

    You would first need to add as one of your Messenger contacts. Then you can invite him in the conversation just by clicking the "Invite" button in Messenger.

    every time i invite someone to join me with tbot it doesnt work, and visa versa, if i am conversing with someone and invite tbot, that other person is kicked out. why? what am i doing wrong

  37. Hi Dave,

    Does the other person have Tbot as her/his contact list?  This might be the reason…

    By the way, Tbot will retire on Feb. 26, 2013.  For more details, see Announcements on our forum site (…/threads).  Thanks, Microsoft Translator Team
