🧠 A speed bump for unnecessary AI use
When a prompt looks like a simple shortcut, MindShield introduces a short pause that gives you a chance to think before relying on AI.
MindShield
Use AI without letting it do your thinking for you.
MindShield adds a brief moment of reflection when you ask AI to do something you could easily think through yourself. It helps you stay actively involved while still using AI when it genuinely helps.

AI makes it easy to stop thinking.
AI can answer questions, write explanations, solve problems, and make decisions almost instantly. That's useful — but it's also easy to start asking AI for things you could have figured out yourself.
MindShield is designed to add a small amount of friction before that becomes a habit.
How MindShield works
A small pause when you need it. No interruption when you don't.
1
Write your prompt
Use your AI assistant normally. MindShield works in the background while you type.
2
MindShield evaluates it
An on-device model checks whether your request appears to be a simple shortcut or a more substantial task.
3
Pause or continue
Simple shortcuts can trigger a brief reflection period. More complex tasks can pass through immediately.
Designed to keep you thinking
MindShield is designed to support AI use, not eliminate it.
⚡ Don't interrupt productive work
Complex prompts, educational requests, debugging, research, and other substantial tasks can bypass the reflection delay.
🔒 Your prompts stay on your device
Prompt evaluation uses an on-device machine-learning model. Your prompts aren't sent to an external server for classification.
🌐 Works across popular AI assistants
MindShield supports ChatGPT, Claude, Google Gemini, and Grok.

AI should be a partner, not a replacement for thinking.
MindShield is built around that idea.
You don't need to stop using AI. You just don't want to automatically outsource every small decision, calculation, explanation, or problem to it.
MindShield creates a small moment where you can decide: "Do I actually need AI for this?"
Your prompts stay private.
MindShield performs prompt classification locally in your browser using a machine-learning model compiled for WebAssembly.
Your prompts are not sent to an external classification server.
No tracking. No analytics. No cloud prompt analysis.
The project is open source, so you can inspect how it works yourself.

Frequently Asked Questions
Everything you need to know about MindShield.
What is MindShield?
MindShield is a privacy-first browser extension designed to help you avoid unconscious AI dependence. By introducing a gentle, brief pause before simple queries, it encourages you to think independently while keeping AI readily available for genuine, complex work.
Does MindShield send my prompts anywhere?
No. Never. Your prompt text never leaves your browser. Classification runs 100% locally on your computer via an on-device machine-learning model compiled to WebAssembly. There are no analytics, no telemetry servers, and no cloud loggers.
Does MindShield block AI?
No. MindShield is not an AI blocker or website restrictor. It acts as an intentional speed bump. When a query is flagged as a basic shortcut, it simply pauses submission for a short reflection period. Once that moment passes, or if your prompt is substantial, you can submit immediately.
Why does MindShield pause some prompts?
Repeatedly using AI for minor tasks can make it easier to rely on AI automatically rather than attempting the task yourself. Pausing simple shortcuts introduces just enough friction to create a brief moment of awareness: "Do I actually need AI for this, or can I quickly think through it myself?"
What is cognitive offloading?
Cognitive offloading is the practice of delegating mental tasks—such as remembering, calculating, reasoning, or analyzing—to external digital tools. While it can be useful and efficient, researchers have raised questions about how repeated reliance on external tools may influence cognitive engagement and independent problem-solving over time.
Which AI assistants does it support?
MindShield currently supports ChatGPT, Claude, Google Gemini, and Grok web interfaces, with ongoing updates to support more platforms.
Is MindShield open source?
Yes. MindShield is entirely open source. You can inspect the classification logic, review extension permissions, or contribute directly on GitHub.
How does the local AI model work?
MindShield packages a compact, optimized classifier compiled to WebAssembly (Wasm). It assesses the complexity, intent, and depth of your query in milliseconds right inside your browser tab—achieving fast, privacy-preserving evaluation without requiring an external API key.
Keep AI useful. Keep your thinking yours.
Add a small moment of reflection to your AI workflow without giving up the tools you use every day.
About MindShield
MindShield is an open-source project created by Janis Flury that explores more intentional ways of using artificial intelligence without automatically handing over reasoning and decision-making to AI tools.
The project includes the MindShield browser extension, research and writing about AI and critical thinking, and interactive experiments exploring AI dependence and cognitive offloading.
