Control whether your conversations are used for Microsoft Copilot model training
Microsoft Copilot model training is a background process that uses your personal chat data from Windows 11 and 10 to teach its AI assistant and make answers smarter for everyone. Turning off this setting stops Microsoft from adding your private questions and personal details to public AI training sets.
You can opt out of this data sharing in a few clicks through your account privacy controls. Disabling the feature blocks Copilot from learning from any of your future chats.
Go to your Copilot Privacy settings and turn off “Training on conversation activity.” If you use voice commands, also disable “Training on voice conversations.” This prevents your chats and audio from being used for AI model training.
Find Your Privacy Settings
Privacy settings control whether Microsoft Copilot uses chats to train AI models. You can access these controls to manage your copilot training opt out preferences. Go to copilot.com, click your profile picture, and select your profile name to open the privacy menu where these options live.
- If you use Copilot on the web (copilot.com): Look for your profile picture. Click it, then choose your profile name. You should then see an option for “Privacy.”
- If you use Copilot built into Windows or macOS: Click your profile picture inside the Copilot window. Then, go to “Settings” and look for the “Privacy” section.
- If you use the Copilot mobile app: Open the main menu, tap your profile picture, and then go to “Account,” then “Privacy.”
Control “Training on conversation activity”
Training on conversation activity determines whether Microsoft Copilot uses your typed chats for AI model training. You can turn this switch off to complete your copilot training opt out for text chats. Locate this setting in your profile privacy menu and switch it off to stop sharing your typed conversations.
What to do: Locate the “Training on conversation activity” setting. Toggle this switch to OFF to prevent conversations from being used for AI model training.


Disabling the AI model training setting stops Copilot from using future chats for AI model improvement. New chat content remains excluded from refining Microsoft's AI models starting immediately after changing this setting.
Check "Training on voice conversations"
Training on voice conversations dictates whether Microsoft Copilot uses your spoken audio inputs for AI training. You need to turn off this toggle as part of your copilot training opt out if you use voice commands. Find this setting in your privacy menu and switch it off to keep your voice chats private.
To prevent Microsoft Copilot from using voice commands for model training, locate the "Training on voice conversations" toggle. Turn this specific toggle OFF. Voice command data remains excluded from future training processes as a result.

Voice recordings or text transcriptions will not improve Microsoft Copilot's ability to understand and respond to spoken language once disabled. Spoken queries stop training the AI model entirely.
