SpeedChat Plus is a way of communicating with other players in Toontown Rewritten using typed phrases and messages. However, it is limited to a dictionary to limit profanity and giving away personal information, both of which are violations of the rules.
If a Toon doesn't have any True Friends, words that are not allowed will appear in red. If a Toon does, words that are not allowed will appear in italics and are visible. When a Toon says one or more words that are not allowed, those words are replaced with appropriate animal noises (woof, meow, squeak, etc.).
To make a thought bubble, type a dot in the beginning of your message. Thought bubbles stay above your Toon's head for longer than spoken messages, but unlike speaking, thought bubbles do not make sounds and stay above your Toon's head until he/she falls asleep or talks. Toons who join a room or a street region after the bubble had been said will not be able to see it.
All characters in the filter are non-control characters in ASCII. Characters not in that range (e.g. Arabic script) cannot be used, and when attempting to write them in the speedchat using Ctrl + V, the will be automatically converted to question marks. Since 2015, if the player types them using their keyboard and attempts to send them, a purple notification message would read "Toontown Rewritten does not currently support non-ascii characters.". Before this feature, sending non-ASCII characters would make the launcher of the sender crash.
- SpeedChat Plus is automatically enabled on all accounts, but can be disabled through the account preferences of the Toontown Rewritten website.
- In Toontown Online, numbers and number names could not be used. However, in Toontown Rewritten, numbers ranging from 1 to 137 (Laff levels, except for 69), promotions' values, as well as some other special numbers (e.g. 9001) can be said.
- Many words that were appropriate for use that were not allowed in Toontown Online's dictionary are allowed in Toontown Rewritten's dictionary.
- Any speech bubble can be instantly removed, rather than waiting for it to expire, by sending a message containing only a period (.). It was required to also type a space and then a backspace in order to do that in late 2014.
