CS2 AI Chatter is a bot that reads the in game text chat during Counter-Strike 2 matches and replies automatically using an AI model, either a local model through Ollama or a cloud model through OpenRouter. It is controlled through a web dashboard that runs in your browser. The bot works without touching the game process itself. CS2 can be launched with a setting that makes it write every chat line to a plain text log file, and the bot watches that file for new messages. To send a reply, it writes a chat command into a config file and simulates a single key press that CS2 is already bound to execute that file, the same action a player would trigger by pressing a key. Because nothing is injected into or attached to the game, the README argues this avoids the kind of tampering that Valve's anti cheat looks for, though it is upfront that this does not make it allowed under the game's terms of service, and that FACEIT or ESEA accounts should not be used with it since their anti cheat systems are stricter and unverified against this tool. You can choose the bot's personality from nine preset tones such as witty, sarcastic, or friendly, and it uses a fast model for quick replies and a smarter model for more involved questions. It includes anti spam controls like reply cooldowns and repetition detection, plus a per player blacklist. The dashboard lets you test the AI outside of a live match, adjust personality and human like behavior such as random delays or typos, and browse OpenRouter models along with their price per message. Setup requires Node.js 18 or newer and is built for Windows, since it depends on simulating a key press through Windows specific code. The project is licensed under MIT.
