In 2025, Google isn’t just a search engine; it’s a generative AI powerhouse shaping how Americans interact with the internet. With Gemini (formerly Bard) now deeply integrated into Google Workspace, Android, Chrome, YouTube, Gmail, and Maps, and AI Overviews (SGE) increasingly taking over search results, the volume and sensitivity of the data Google collects have evolved dramatically. It’s no longer just about your browsing history or what you search for; it’s about what you ask the AI, your voice commands, your creative prompts, your location patterns, and how Google AI interprets and summarizes your personal world.

For users in the United States, online privacy has shifted from a preference to a necessity. Many people want more control—whether to stop their data from training Google’s LLMs (Large Language Models), reduce personalized ads, protect personal information from AI automation, or simply enjoy a cleaner and more private search experience. That’s where learning how to delete Google AI data becomes essential.

This guide will walk you step-by-step through a complete Google AI data deletion, including how to wipe Gemini chat logs, disable AI activity tracking, turn off AI Overviews in search, and prevent Google from using your information for generative AI model training. If you’re ready to reclaim your digital footprint and take back your privacy, this guide gives you everything you need—simple, actionable, and designed for U.S. users concerned about data collection, artificial intelligence, and online security.

Why Deleting "Old" History Isn't Enough Anymore

In the past, privacy meant deleting your browser history. Today, Google's AI models—specifically Gemini (formerly Bard) and the Search Generative Experience (SGE)—collect different types of data:

• Prompt History: The specific questions and creative prompts you send to Gemini.
• Interaction Data: How you rate AI responses (thumbs up/down).
• Contextual Data: Information from your Workspace (Docs, Gmail) if you have Gemini extensions enabled.

If you don't actively manage this, Google retains this data to "improve machine learning models." Here is how to scrub it clean.

The Difference Between "Search History" and "AI Data"

To rank for data privacy, you must understand what you are deleting. Google separates its data buckets:

• Web & App Activity: This is your traditional search history and Chrome browsing data.
• Gemini Apps Activity: This is a separate vault containing your conversations with Google’s LLM (Large Language Model), including uploaded images and document analysis.
• Voice & Audio Activity: Raw audio files from Google Assistant interactions.

Deleting one does not always delete the others. Below is how to handle each specific sector.

How to Delete Google Gemini Data (The New Standard)

Google Gemini is now the default generative AI system powering Google Search, Workspace, Android voice commands, and conversational searches in the U.S. Because Gemini logs include conversations, personal queries, and sensitive prompts, this data is treated differently from traditional browser or search history. To protect Google AI chat privacy, Google sometimes allows human reviewers to read anonymized conversations for improving responses and training the AI model—which makes knowing how to Delete Google Gemini history more important than ever.

Step-by-Step Guide: Delete Google AI Activity & Gemini Chat History

1. Go to Google Account Settings: Visit your Google Account → Data & Privacy dashboard.
2. Scroll to “History settings”: Look for a dedicated section labeled Gemini Apps Activity (This is separate from Web & App Activity or YouTube History).
3. To Delete Specific Gemini Prompts or Conversations:
   • Select Manage History
   • You’ll see a timeline of voice prompts, typed messages, and AI queries
   • Click the “X” next to any item to remove instantly from your account
4. To Delete All Google AI Data at Once:
   • Click the Delete dropdown
   • Select Delete all time
   • Confirm to permanently erase your Gemini logs from your account

This ensures your creative prompts, voice commands, and AI-generated content are wiped from Google servers improving your AI privacy protection and reducing unwanted personalization.

Important AI Privacy Setting: “Turn Off” vs. “Delete”

Deleting your history clears past conversations, but Google will continue storing future chats unless you disable activity tracking.

To stop Gemini from saving new conversations:

• Toggle Gemini Apps Activity → OFF

When turned off:

• Future chats are no longer stored long-term
• Data is excluded from LLM training (Large Language Models)
• Personalized AI Overviews and Gemini suggestions become limited
• Ideal for users seeking private AI search in the U.S.

Even when paused, Gemini retains AI conversations for up to 72 hours for moderation, abuse prevention, and legal compliance but they cannot be used for training Google AI during this temporary window.

This means:

• Your data is safer
• It won’t influence future AI responses
• It contributes less to your online behavioral profile

How to Turn Off “AI Overviews” in Google Search (U.S. Privacy Guide 2025)

By late 2025, one of the biggest frustrations among U.S. users is Google’s AI Overviews    previously known as “Search Generative Experience (SGE).” These AI summaries collect information from your searches, browsing behavior, and interaction patterns, then rewrite that content into a single AI response at the top of the page. While designed for convenience, many Americans want to remove AI summary Google features due to:

• Privacy concerns over AI data scraping
• Reduced visibility of organic search results
• Increased misinformation risk in generated answers
• Loss of full publisher context and source transparency

Although Google removed the ability to officially Turn Off AI Overviews , two proven methods still allow searchers to reclaim a clean, traditional results page.

Method A: Use the “Web” Filter (The Official Google-Approved Method)

The Google Web Filter strips away AI Overviews, shopping modules, and knowledge panels    leaving you with classic 10-blue-link results and better Google AI privacy control.

How to activate the Web filter:

1. Perform a search like normal on Google
2. Look under the search bar   tabs such as All, Images, News
3. Select Web

Result:

No generative AI content. No auto-summaries. Only real website results.

This method is recommended for users who:

• Want a familiar browsing experience
• Prefer original source content over AI rewrites
• Want to reduce AI data profiling

Method B: Use the “udm=14” URL Parameter (The Power-User Trick)

If you want to always disable SGE and skip AI Overviews automatically, this is the most effective workaround. The udm=14 flag forces Google into “Web mode” on every search.

There are two ways to use it:

Manual Method

Add the following parameter to any Google search URL:

&udm=14            

Example:

https://www.google.com/search?q=Delete+Gemini+history&udm=14            

Permanent Browser Fix (Chrome, Edge, Brave)

1. Go to Browser Settings → Search Engine
2. Select Manage Search Engines
3. Add a new custom search engine
4. Under URL, enter:

https://www.google.com/search?q=%s&udm=14            

5. Save and set it as Default

Benefit of Method B:

Every search entered from your address bar automatically removes AI Overviews , without adjusting settings every time.

This solution is especially useful for users prioritizing:

• U.S. Digital Privacy
• Regaining control over search results
• Blocking AI-generated rewriting of personal search queries

Why This Matters for U.S. Users

With Google increasingly using generative AI to log intent, monitor behavior patterns, and store query context, removing AI layers helps minimize:

• AI training on personal search activity
• Profiling for targeted advertising
• The risk of inaccurate or biased summaries influencing choices

Whether you're concerned about data collection, online safety, or just want AI-free Google Search, these methods work today   even after Google removed the original disable button.

Securing Voice Data: Google Assistant & Audio (Protect Your Conversations in the U.S.)

While text-based generative AI is dominating headlines, voice data may be an even bigger privacy concern. Every time you say “Hey Google” to your Android phone, Chromebook, Nest Hub, Nest Mini, or Pixel Watch   your voice commands can be recorded, stored, and sometimes reviewed by human evaluators to improve AI audio recognition. This raises major concerns for Americans who want to Stop Google listening , reduce AI profiling, and regain control of their personal conversations.

To protect yourself, you must take action directly within your Google Account settings.

How to Disable Google Assistant Voice Recording

1. Open your Google Account → Data & Privacy
2. Scroll to Activity Controls
3. Locate Include voice and audio activity
4. Turn this setting OFF

What this does:

When switched off, Google stops saving your audio clips long-term. Your voice will still trigger Assistant actions, but the recordings are no longer used for AI training or analysis.

Why Voice Privacy Matters in 2025

If this setting remains enabled:

• Google may store audio snippets from:
• Smart speakers (Nest/Home)
• Android devices
• Google Assistant–enabled apps
• These clips can reveal sensitive personal details like:
• Medical discussions
• Financial questions
• Children’s voices
• Home background sounds

Turning it OFF greatly reduces AI data scraping and voice surveillance risks .

Delete Google Voice Recordings Already Collected

For past conversations that may already be stored:

• Go to Manage Activity
• Review voice clips and press Delete
• Optionally choose Delete all time to wipe your Google Assistant audio history permanently

This is especially recommended for users with shared household devices .

Enable Auto-Delete for Smart Speaker Privacy

Even with everything turned off, Google may temporarily store audio to process requests. To prevent audio data retention longer than necessary:

1. Under Activity Controls → Auto-delete
2. Set to 3 months (Recommended for U.S. privacy laws)
3. Confirm to apply across all past and future voice activity

Benefit:

Your voice recordings are automatically removed quarterly    no manual cleanup needed .

Additional Tip: Mute Physical Microphones

For maximum protection:

• If your Nest or Google smart speaker has a hardware mic switch, toggle it OFF whenever not needed.
• This prevents accidental activations like misheard hotwords (“OK Google”).

Best practice for U.S. households concerned with always-listening devices

The “Results About You” Tool: Removing PII (Protect Your Identity in the U.S.)

With the rise of Google AI features like AI Overviews and Gemini-powered search highlights, personal details found online can now be automatically summarized and displayed to strangers. This includes highly sensitive PII (Personally Identifiable Information) such as:

• Home address
• Personal phone number
• Email address
• Workplace details
• Full legal name
• Private contact profiles

To help users in the United States defend their privacy, Google launched a dedicated Google privacy tool called Results About You. This system is specifically designed to Remove personal info from Google search results and reduce the chances of AI scraping your identity data.

How to Find and Use “Results About You” (Updated for 2025)

1. While logged into your Google account, search:
   Results about you
2. Click the privacy dashboard result (or access it through the latest Google App)
3. Provide the data you want monitored:
• Name
• Phone number
• Email address
• Physical home address
4. Google will continuously scan the public web for matching PII in search results
5. If a match is found:
• You will receive an alert
• Click Request Removal to de-index the harmful result

What Happens After Removal is Requested?

When removal is approved:

• The sensitive information is de-indexed (removed from Google Search)
• It becomes much harder for people  or AI systems  to find your personal data
• Your PII is less exposed to identity theft and doxxing attempts

This is particularly important for U.S. users because:

• Data brokers often publish and resell addresses and contact info
• AI models scrape the open web to train search intelligence
• PII appearing in AI summaries can spread faster than search listings

SEO + Privacy Win

Requesting removal doesn’t only enhance safety   it also helps Google’s algorithm learn that this data is private, making it harder for it to resurface later.

Bonus Benefit:

This signals US data privacy compliance, supporting stronger protections aligned with laws like CCPA and state-level digital rights acts.

Extra U.S. Protection Tips

To further increase your identity protection online:

• Enable Google’s Dark Web Monitoring (built into the same tool)
• Periodically review alerts from the Google Safety Center
• Lock down people-finder sites and data broker profiles
• Keep phone numbers and addresses off public social media

Advanced Tips for Website Owners: Block AI Scrapers & Protect Your Content

If you are a digital creator, blogger, publisher, or online business in the United States, your content has likely already been used to train Google’s generative AI   including Gemini. Traditional search engine crawlers like Googlebot only index content for search ranking, but Google now deploys new AI-focused crawlers designed to copy and process your content for LLM training and AI summaries.

To prevent this unauthorized reuse and protect your copyrighted assets , you must specifically block Google’s AI crawler   not the standard search crawler.

Google provides a special user-agent called:

Google-Extended

This user-agent is responsible for feeding Gemini, AI Overviews, and other generative AI systems.

How to Block Google AI Training (Robots.txt Method)

Modify your website’s robots.txt file by adding:

User-agent: Google-Extended
Disallow: /

What this does:

• Still allows Google Search ranking (your site remains visible as normal)
• Blocks Google AI from using your content to train its LLM models
• Stops content from appearing inside AI Overviews, summaries, and chat-style answers

Why Creators in the U.S. Must Use This Setting in 2025

Generative AI systems can:

• Summarize your content without credit
• Extract key information and rewrite it
• Replace clicks to your website with AI-generated answers
• Potentially harm your site’s revenue and traffic

Declaring content restrictions using Google-Extended robots.txt protects:

• U.S. copyright rights
• Brand-owned content
• Intellectual property value
• Legal compliance protections under DMCA

Optional: Allow Indexing but Block AI Everywhere

For maximum protection, creators can also block other AI crawlers and LLM data scrapers using:

User-agent: *
Disallow: /ai/
Disallow: /feeds/
Disallow: /private/

You may also add additional known AI crawler rules like:

User-agent: GPTBot
Disallow: /
User-agent: CCBot
Disallow: /
User-agent: Amazonbot
Disallow: /

These prevent major companies from retraining AI models on your work without permission.

Pro Tip for SEO-Conscious Creators

If you rely on search traffic and want to stay compliant with Google Search Essentials, make sure:

You do NOT block:

User-agent: Googlebot            

User-agent: Googlebot-Image            

Blocking these would remove your website from Google Search , not just AI systems.

In Short

Implementing these rules ensures your original work is not quietly absorbed into massive AI datasets that generate profit without proper attribution or reward.
