Chester is a chat-bot that can be added to your server. Players can chat to him and from what us, the developers, have found, the responses can be hilarious!


  • Logs all messages by players.
  • When Chester is mentioned, he replies with one of his saved messages.
  • Works in any language (except in the beginning, where he stores 3 English sentences)


  • Just chat like normal, and say 'Chester' when you want him to respond




  • Negate chester.trigger to stop Chester from logging them (eg. -chester.trigger)
  • Negate chester.log to stop people from being logged by chester

How does Chester work?

Chester logs every single message said by players and collects them in a database. Whenever a player mentions his name, he responds with the most appropriate reply, as selected from his database.

If your Chester doesn't seem to make sense at first, this is normal, Chester will learn from chat and it may take some time for him to gather enough information in his brain.

Chester's responses can be highly intelligible and amusing :D!

    25KiB plugin requires 35 coders? Does chester also hack into the N.S.A. for me?

    no it isn't, i tried to program a plugin like this but i couldn't because it was too hard to program something that can make connections between things in different players's sentences and reply accordingly. And also, why would it take time to learn before it started working properly, if it was simply sending the player a random message this would be pointless.

    I am guessing they all added random chat messages to it. And like half of them are prominent java plugin devs and even retired bukkit staff.

    No Offence,
    but You have a LOOONG list of authors, who made this plugin.
    Isn't this plugin basically;
    Checking if someone wrote something in chat.
    Get Player.
    Get Message.
    If Message is "Chester", then send a random message to "Player".
    If Message is not "Chester", then ignore.

    Why would you need like 50 authors?
    True, it might be easier with more people, but I really think that list is too long.

    public void onEnable() {
    getLogger().info("Bringing out Rex the Test Dog...");
    getLogger().info("Feeding him...");
    getLogger().info("Reasurring him...");
    getLogger().info("Sending Rex the Test Dog...");
    getLogger().info("Buying new Rex...");
    getLogger().info("Plugin intialization complete.");
    } ZBDH80da9df1ac9a4c11872f7d782aa9084c

    Will this work in a 1.8 server? Or is it too outdated?
