+# AI Disclaimer
+
+*Last Updated: February 11, 2026*
+
+## What the AI Study Assistant Does
+
+This site includes an AI-powered study assistant available on certification study pages. It offers two features:
+
+- **Q&A Mode** — Ask questions about the content on the current page and receive contextual answers
+- **Flashcard Mode** — Generate interactive flashcards from the current page's study material
+
+## How It Works
+
+When you use the assistant:
+
+1. The **text content** of the current page is extracted from your browser
+2. Your question (or a flashcard generation request) is sent along with the page content to a proxy server
+3. The proxy forwards the request to **Google Gemini** (an AI language model) for processing
+4. The response is returned to your browser and displayed
+
+The proxy server is a **Cloudflare Worker** that validates requests and enforces rate limits. It does not store any data.
+
+## What We DON'T Store
+
+- ❌ **No conversation history** — Each page visit starts fresh; nothing is saved between sessions
+- ❌ **No personal data** — No login, no accounts, no identifying information
+- ❌ **No cookies** — The assistant does not set any cookies
+- ❌ **No page content stored** — Content is sent per-request and discarded immediately
+- ❌ **No training on your data** — Your queries are not used to train AI models
+
+## Usage Limits
+
+To ensure fair usage and manage costs, the assistant has rate limits:
+
+- **10 requests per minute** per user
+- **100 requests per day** per user
+
+If you exceed these limits, you will receive an error message. Limits reset automatically.
+
+## Accuracy Disclaimer
+
+::: warning Important
+AI responses **may be inaccurate, incomplete, or outdated**. The assistant generates answers based on the page content and an AI model — it is not a certified instructor or an official exam resource.
+:::
+
+**Always verify answers** with official vendor study materials:
+
+- [Microsoft Learn — Certifications](https://learn.microsoft.com/certifications/)
+- [AWS Certification — Exam Guides](https://aws.amazon.com/certification/)
+- [Google Cloud — Certification](https://cloud.google.com/learn/certification)
+- [GitHub Certifications](https://resources.github.com/learn/certifications/)
+
+The AI assistant is a **supplementary study tool**, not a replacement for official exam preparation materials.
+
+## Limitations
+
+- Answers are scoped to the **current page only** — the assistant cannot search across the entire site
+- The AI may **hallucinate** facts, especially for nuanced or edge-case topics
+- Generated flashcards may not perfectly match exam objectives
+- The assistant does not have access to the latest exam updates unless the page content has been updated
+
+## Powered By
+
+- **[Google Gemini](https://ai.google.dev/)** (Flash-Lite) — AI language model
+- **[Cloudflare Workers](https://workers.cloudflare.com/)** — Serverless proxy
+
+## Questions?
+
+If you have concerns about the AI assistant, open an issue on [GitHub](https://github.com/gobinathm/Notes/issues).
+
+---
+
+**Summary:** The AI assistant answers questions and generates flashcards from page content using Google Gemini. No personal data is collected or stored. Always verify AI responses with official exam guides.
