This project is unfortunately dead, character.ai switched to websocket, and they implemented it into a IIFE which makes it impossible do access their socket reliably to modify it
the only way to revive this would be directly manipulating outgoing packets by self MITM
Install at here: https://greasyfork.org/en/scripts/467254-text-injector
inject text directly into your chats, useful for creating permanent memories, or just being wierd with the ai
whatever you write into that box, it's going to spit it to the ai together with you messages
Example: you write "Looks around" in the box
when you send a message to the bot
you are just going to see your message like regular, but the bot will actually receive:
looking around
your message here
