Security-first web scraper that redacts sensitive information before you paste into LLMs Eliminate Data Exfiltration Risks. Secure Your AI Context. Every time you provide a raw webpage to a cloud-based Large Language Model (LLM), you risk leaking proprietary data. Webpages are saturated with non-essential identifiers: internal project names, personal contact information, API keys, and metadata that should never leave your local environment. Data Bouncer is a high-fidelity, local-first privacy layer. It intercepts web content, strips away noise, and redacts sensitive identifiers before they are transmitted to external AI providers. ==== Core Features ==== Deterministic Markdown Extraction: Utilizes industry-standard parsing to convert complex webpages into clean, structured Markdown. This reduces token consumption and improves the accuracy of AI responses. On-Device Automated Redaction: Leverages Chrome’s native Gemini Nano (on-device AI) to identify and mask PII (Personally Identifiable Information) and sensitive data strings locally. Non-Custodial Architecture: Unlike traditional scrapers, Data Bouncer operates entirely within your browser's memory. Your data is never stored, logged, or transmitted to our servers. Structured Context Bundling: Aggregate content from multiple sources into a single, sanitized prompt ready for immediate use in professional workflows. Compliance-Ready AI Usage: Bridge the gap between productivity and corporate compliance. Data Bouncer allows employees to use public LLMs while maintaining a rigorous security posture, preventing the accidental "Shadow AI" data leaks that trigger audits. Optimized for LLM Performance: Webpages are full of junk—navigation bars, ads, and tracking scripts. Data Bouncer extracts only the signal, providing the LLM with the exact context it needs for reasoning and synthesis. ==== Technical Specifications & Transparency ==== Open Source: Full source code transparency for security auditing and community contribution. Zero-Latency Processing: On-device execution ensures that sanitization happens in milliseconds, not seconds. Framework Integration: Built on readability.js and turndown.js for reliable content extraction. API-Free Security: No external API keys or subscriptions to third-party data processors are required for core functionality. The Standard for Secure AI Interaction Extract: Convert any webpage to clean Markdown. Sanitize: Automatically redact PII using local AI. Transfer: Move secure, high-fidelity context to your LLM of choice. Protect your proprietary data.
