Chat with your custom AI personas and local on-device AI (Gemini Nano) anywhere on the web. Meet NanoBot: Your Lightweight, Privacy-First AI Assistant Built Directly Into Your Browser! Are you tired of opening a new ChatGPT tab every time you want to ask a quick question, breaking your natural web-surfing flow? Or are you worried about sending sensitive work texts, proprietary code, or personal information to external servers? NanoBot is a lightweight, secure Chrome extension that brings cutting-edge on-device AI technology and intuitive productivity tools directly to your browser—without compromising your privacy. ================================================== 🔥 Why Install NanoBot? ================================================== 100% Local AI for Ultimate Privacy Leverage Google Chrome's experimental on-device AI model (Gemini Nano) to process requests locally. Since not a single byte of your data is sent to external servers, you can safely analyze sensitive business documents and proprietary source code with absolute peace of mind. Seamless Workflow with a Flexible UI No more switching tabs. Use our clean "Floating Widget" overlay on any webpage, or pin the conversation to the "Sidepanel" to collaborate with AI naturally while keeping your focus exactly where it needs to be. An All-in-One Productivity Hub NanoBot is more than just a chatbot. It combines custom Skills, a Prompt Runner, smart memos, global bookmarks, a Lingo language tutor, real-time alarms, and a private AI Buddy—all in one lightweight extension. Strict Security & Extension Policy Compliance We prioritize browser safety. NanoBot strictly complies with Chrome Web Store security guidelines by completely avoiding unsafe dynamic code execution (eval()). Our built-in calculator and unit converter run on a secure, custom-built token parser. ================================================== 💡 Core Features ================================================== - Local Gemini Nano Engine: High-performance, on-device local inference that runs even when you are offline. - External LLM Bypass: Need deeper, more complex answers? Easily connect your own OpenAI-compatible API endpoint in the settings. - Custom Skills: Define any AI role (translator, code reviewer, summarizer, etc.) as a reusable prompt-based Skill. Activate it instantly from the sidebar with a single click to instantly shape the AI's behavior. - Prompt Runner: Select a saved Skill, type your input, and the AI executes it immediately. Results can be sent directly to the Memo or the AI Document Viewer. - Global Bookmarks: Register your most-visited sites (GitHub, ChatGPT, Stack Overflow, etc.) and open them instantly with one click—without ever leaving your current tab. - Lingo Tutor: A daily language learning coach that delivers a personalized expression card every day. Set your target language (English, Japanese, Chinese, Spanish, French, German, Vietnamese), difficulty, and topic. Cards include the sentence, pronunciation guide, vocabulary chips, and a tutor note with a real example dialogue in the target language. All cards are saved to your personal Vocabulary Archive. - Inspirational Quote Header: A rotating pool of 80+ famous quotes displayed at the top of the chat. Click any quote to instantly get a friendly AI explanation in your UI language. - Real-time Smart Alarms & Reminders: A background scheduler (Alarms API) that reliably delivers desktop push notifications at your scheduled times, even if the browser is closed. Lingo Tutor cards can also be delivered automatically on a daily schedule. - Shadow DOM Architecture: The floating widget works seamlessly on top of any webpage without interfering with or breaking the site's original CSS layout. - Standalone AI Buddy System: Launch an independent personal AI character with custom personas, memory, and an encrypted private diary—completely isolated from your main conversation session. - Smart Drag Actions: Select and drag any text on a webpage to instantly send it to the side panel for quick summaries, translations, or interactive AI feedback. - Smart Calculator & Unit Converter: Quickly convert common real estate and temperature units (Pyung <-> m2, Celsius <-> Fahrenheit) and solve expressions on the go. - Stunning Dark Mode & Customization: Features a premium, eye-friendly dark theme by default, with options to customize accent colors and chatbot profile names/avatars. ================================================== ⚙️ How to Activate On-Device AI (Gemini Nano) ================================================== To experience local AI inference, you will need to enable Chrome's experimental developer flags once.
