Like many of you, I love AI-assisted browsing—summarizing long articles, distilling key takeaways, extracting clean data tables, drafting quick replies, and fact-checking. However, I’ve always been uneasy with how traditional AI browser extensions work under the hood: 1. They inject permanent background scripts across every single tab and website you visit. 2. They ship every paragraph and personal document to remote third-party cloud servers. 3. They store private API keys in plain text directly on your disk. With Chromium introducing **Chrome Built-in AI (Gemini Nano)** directly into the browser engine, I wanted to build what a modern browser copilot *should* look like: 🚀 **True Local-First AI:** When your browser supports it, summarization, tone rewriting, and Q&A run 100% on your device hardware. Zero cloud latency, zero network calls, and absolute confidentiality. 🛡️ **Deterministic PII Shield:** Even when you optionally escalate a query to the Cloud, our built-in shield automatically masks Credit Cards (Luhn-validated), IBANs (Mod-97 checksum), Italian fiscal codes, phone numbers, and API tokens *before* anything is transmitted or cached. 🔐 **Zero-Persistence BYOK:** Want the extra depth of Gemini 3.8 Flash? Bring your own API key. It lives exclusively in volatile session RAM (`chrome.storage.session`)—it is never written to disk and vanishes the moment you close Chrome. 📊 **DOM Table Extractor:** Instantly converts nested HTML tables and lists into clean Markdown, CSV, TSV, or JSON with one click. ⚡ **Clean Manifest V3 Architecture:** No permanent global content scripts. Scripts are injected strictly on-demand when you explicitly invoke an action. 🌍 **6 Native Languages:** Full cognitive and UI localization in English, Italian, German, Spanish, French, and Portuguese. --- NanoPilot AI is lightweight, privacy-respecting, and completely free to use.
