Dobby
Overview
A free house elf running on local Gemini Nano
v0.4 — May 2026 - Adding custom system prompt feature. — Dobby is a tiny, friendly AI helper that lives in Chrome's side panel and runs entirely on your own computer. It uses Chrome's built-in Gemini Nano model — no API keys, no signups, no cloud round-trip. Your prompts and conversations never leave your device. What you get: - A clean side-panel chat that streams replies as they're generated - Markdown rendering — bullet lists, **bold**, code blocks, tables - A memory bar showing how full Dobby's context window is, with a warning before it overflows - A "↻ New" button to start fresh whenever you want - Language toggle between English and 繁體中文 (Taiwan vocabulary) Requirements: - Chrome 138 or newer - Windows 10/11, macOS 13+, Linux, or Chromebook Plus - ~22 GB free disk space (Chrome downloads the Gemini Nano model on first use) - A GPU with more than 4 GB VRAM, OR 16 GB RAM + 4 CPU cores - Unmetered network for the first model download Privacy: Dobby does not collect, transmit, or store any user data. All inference happens locally via Chrome's on-device Gemini Nano. The extension makes zero network requests of its own. Open source vibes — built as a small, readable Manifest V3 extension. If something breaks or you have ideas, feedback is welcome. v0.4 -- 2026/05更新 加入個人化系統提示功能。繁體中文使用者建議保留語言鐵律。 多比是一個住在 Chrome 側邊欄的迷你 AI 小幫手,全程在您自己的電腦上執行。它使用 Chrome 內建的 Gemini Nano 模型,不需要 API 金鑰、不需要註冊帳號,所有對話完全不會離開您的裝置。 主要功能: • 簡潔的側邊欄聊天介面,逐字串流輸出 • 支援 Markdown 排版 — 條列清單、**粗體**、程式碼區塊、表格 • 記憶條顯示目前的對話上下文使用量,超載前會提醒 • 「↻ 新對話」按鈕,隨時可以重新開始 • 語言切換:繁體中文(台灣用語)/English 系統需求: • Chrome 138 或更新版本 • Windows 10/11、macOS 13+、Linux 或 Chromebook Plus • 約 22 GB 可用硬碟空間(Chrome 首次使用時會下載 Gemini Nano 模型) • 顯示卡 VRAM 大於 4 GB,或 16 GB 記憶體 + 4 核心 CPU • 首次下載模型時需要未限流的網路連線 隱私說明: 多比不會收集、傳送或儲存任何使用者資料。所有推論都透過 Chrome 內建的 Gemini Nano 在本機執行,擴充功能本身不會發出任何網路請求。 以小巧、易讀的 Manifest V3 擴充功能打造。歡迎回報問題或提供建議。
