NanoPilot AI
Hybrid on-device & cloud AI copilot with strict privacy
NanoPilot AI is a privacy-first Chrome copilot powered natively by on-device Gemini Nano with optional Cloud escalation. Summarize web pages, rewrite text, and extract clean DOM tables into Markdown, CSV, or JSON with zero cloud latency. A deterministic PII Shield automatically masks cards, IBANs, tax codes, and API tokens. For Cloud mode, bring your own Gemini key—stored strictly in volatile session RAM, never persisted to disk. Fast, local-first, minimal MV3 permissions, and 100% free.
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.

Who hunted NanoPilot AI?
NanoPilot AI was hunted by Rocco Caruso. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.
