Browser AI Lockdown: Disable Built-In Browser AI by Policy
Chrome, Edge, Brave, and Firefox now ship AI assistants turned on by default. ShadowLock disables them through enterprise policy — and blocks Google's conversational AI Mode in search — so no one approved an AI you can't see.
What is browser AI lockdown?
Browser AI lockdown disables the AI assistants that browsers now ship with — Gemini in Chrome, Copilot in Edge, Leo in Brave, and Firefox AI — using enterprise policy enforced by the ShadowLock agent. It removes an AI surface that arrives turned on by default and that web filters and DLP tools don't govern.
enterprise policy controls across four browser families — Chrome, Edge, Brave, and Firefox.
AI you never installed, already running
The AI in Chrome and Edge didn't arrive through an app store or a download you can block. It shipped with a browser update, enabled by default, with read access to whatever's on the page. To most security tools it's invisible — it's part of the browser.
ShadowLock disables it the way it should be disabled: through managed enterprise policy, locked so users can't flip it back, with drift detection if anyone tries. For web AI tools and the AI baked into specific sites, pair it with shadow AI detection.
How browser AI lockdown works.
Policy at the browser, the extension where policy can't reach.
Disable the AI built into the browser
The Windows agent writes enterprise policy that turns off the browser's own AI: Gemini in Chrome, Copilot in Edge, Leo in Brave, and the AI features in Firefox. 22 policy values across four browser families, applied silently.
Block Google's AI Mode in Search
Google Search's conversational AI Mode isn't reachable by browser policy, so the ShadowLock extension handles it directly — redirecting AI Mode back to standard results while ordinary search stays completely untouched.
Stays locked, and tells you if it drifts
If a policy value is removed or changed, the agent restores it on the next reconcile and the device shows an AI-drift flag until it's back. Enforcement is idempotent and quiet — it only acts when something has actually changed.
Pairs with app control for AI-native browsers
Built-in AI lockdown covers the mainstream browsers. AI-native browsers like Perplexity Comet, ChatGPT Atlas, and Arc have no policy lever to disable AI, so ShadowLock blocks those at the application layer instead — honest coverage, no gaps glossed over.
Browser AI lockdown FAQ
What is browser AI lockdown?
Browser AI lockdown disables the AI assistants that browsers now ship with — Gemini in Chrome, Copilot in Edge, Leo in Brave, and Firefox AI — using enterprise policy enforced by the ShadowLock Windows agent. It removes an AI surface that arrives turned on by default and that web filters and DLP tools don't govern.
Which browsers and AI features does it cover?
It covers Chrome (Gemini, "Help me write", AI in the address bar and history), Edge (the Copilot sidebar and Microsoft 365 Copilot chat), Brave (the Leo assistant), and Firefox (AI chatbot and related features) — 22 policy values across those four families. The extension additionally blocks Google Search's AI Mode, which sits outside browser policy.
Does it block AI-native browsers like Comet or Atlas?
Not through this control — AI-native browsers such as Perplexity Comet, ChatGPT Atlas, and Arc have no enterprise policy to switch their AI off, because AI is the product. ShadowLock blocks those browsers at the application layer with its desktop app controls instead, so the coverage gap is closed a different way.
Can users turn the AI features back on?
No. The features are disabled through managed enterprise policy, so the toggles are locked rather than merely flipped off. If someone deletes a policy value to re-enable AI, the agent detects the drift on its next reconcile, restores the value, and flags the device until it's compliant again.
Is this the same as blocking ChatGPT?
No. Browser AI lockdown governs the AI baked into the browser itself. Web-based AI tools like ChatGPT, Claude, and Gemini's own site are handled by ShadowLock's shadow AI detection, AI DLP, and data-sharing controls. Together they cover both the AI in the browser and the AI on the web.
