What Should I Share With AI?
AI becomes more useful when you give it context. That makes understanding what you're sharing more important, not less.

The quick version
What you need to know:
Use the NEED → MINIMIZE → CHECK SETTINGS framework
NEED: Does the tool actually need this? MINIMIZE: Share only what it needs; redact names and account numbers. CHECK SETTINGS: Review privacy settings to understand what happens to what you share.
Different information has different sensitivity levels
Public information is lower risk. Personal details need more consideration. Passwords, account numbers, financial info, medical details, and other people's information are higher sensitivity.
Training is one privacy question, but not the only one
Ask also: Is conversation retained? Can humans review it? Are connected apps accessing other data? Can I delete data later? Different tools have different answers.
Share intentionally—not automatically
You wouldn't tell a stranger your password. Apply the same principle to AI tools: share what's needed to help you, keep everything else private until you understand why you're sharing it.

The framework and information sensitivity levels
NEED → MINIMIZE → CHECK SETTINGS
NEED
Does the AI tool actually need this information to help you?
MINIMIZE
Share what the tool needs, not everything you have. Redact names, account numbers, identifying details when you can.
CHECK SETTINGS
Review the tool's privacy settings. Understand what happens to what you share.
This is how you share intentionally. You're giving the AI what it needs to help you, while keeping unnecessary information private.
Information Sensitivity Levels
Lower Concern: Public information, general questions, brainstorming, basic information already shared publicly. Example: "How do I make pasta?" or general information about a public figure.
Think First: Personal preferences, opinions, descriptions of situations where privacy matters. Examples: Health concerns, work situations, family dynamics. These are reasonable to share depending on context and tool, but consider: Do I want this used to train the model? Will I regret sharing this later?
Higher Sensitivity: Passwords, Social Security numbers, account information, financial details, medical information, information about other people without consent, proprietary work information. These generally should not be shared with AI tools unless absolutely necessary, and you've considered the risks.
Use this framework with each tool. Different tools have different protections and default settings.
Privacy questions beyond training
Training is one privacy question. But there are others:
- Is the conversation retained or deleted?
- Can humans review what I shared?
- Are connected apps accessing other information?
- Can I access or delete my data later?
- Where is my data stored?
Different tools handle these differently. Check the tool's privacy settings and documentation.
Connected apps can share more than you realize
Many AI tools can connect to other apps and services—email, calendar, cloud storage, browsing history, photos.
Ask yourself: What can it access? What will it do with that access? Can I disconnect it later?
You can usually turn off connected-app permissions in the tool's settings.
Public sharing is different from private
If you use a "share link" or "public share" button in an AI tool, your conversation (or part of it) becomes public.
Remember: Private conversation + public share button = potentially public information.
Specific tool settings and general strategies
ChatGPT Settings (OpenAI)
ChatGPT has a "Data Controls" setting in Settings.
- "Improve the model for everyone": When ON, chats may train models. Turn it OFF to prevent this (personal-user setting).
- Memory: ChatGPT remembers details across conversations. Separate from model training. You can disable it.
- Temporary Chat: Retained 30 days then auto-deleted. Not used for training while temporary. Can still use existing personalization.
Google Gemini Settings
Gemini has a "Keep Activity" setting.
- Keep Activity ON (default): Chats saved and may improve Google services and AI models.
- Keep Activity OFF: Future chats not used for training (except feedback). Chats won't appear in activity; features requiring saved activity may be unavailable.
General Strategies
- Don't paste full passwords or account numbers. Share only what's needed or redact sensitive parts.
- Use pseudonyms instead of real names when describing situations.
- Review connected-app permissions regularly. Disconnect any you're not using.
- If sharing higher-sensitivity information, consider whether a public AI tool is right, or if the tool's privacy protections are sufficient.
Put it in context
Share intentionally. Give AI enough context to help without automatically giving it everything.
You wouldn't tell a stranger your password. You wouldn't email medical history to a random business. Apply the same principle to AI tools:
Share what the tool needs to help you. Keep everything else private until you understand why you're sharing it.
Do I have the right to share this with this tool? Is this information mine to share? Different answers lead to different choices. That's how you stay in control.
