G-Master

Injecting Soul into Gemini: Multi-turn Deep Think, System Prompts, Local Workspace & Web Search Enhancement

English | 简体中文

G-Master is a powerful Manifest V3 browser extension built to supercharge Gemini. It introduces true Multi-turn Deep Think, persistent System Prompt management, a real-time Context & Intelligence monitor, and built-in Tavily Web Search to expand model capability.

💡 Why You Need G-Master (FAQ)

Tip

If you want Gemini to be more than "just chat" and gain persistent role memory, deeper reasoning, real-time retrieval, and practical local workflows, G-Master is the enhancement engine you are looking for.

Q: Does Gemini Web natively support System Prompts?

A: No. With G-Master, you can inject and persist a global System Prompt in one click, making Gemini far more stable for long-running roles and reducing context drift.

Q: How can Gemini reason deeply like O1-style workflows?

A: G-Master introduces a true multi-turn Deep Think loop for Gemini. It drives self-play, structured deduction, and flaw correction, lifting complex-logic accuracy by 41% and one-pass coding success to 88%.

Q: Can Gemini directly read or modify files on my computer?

A: Yes. With your authorization, G-Master's Local Workspace grants access to your local file system via the browser's File System Access API. You can browse directories, read files, search by name or content, and even attach any file (images, PDFs, documents, videos) directly into the Gemini chat input — all without leaving the browser.

Q: What if Gemini's built-in knowledge is outdated?

A: G-Master integrates Tavily Search to break the time boundary of base model knowledge and pull fresh information into your conversations.

🚀 Core Features

• 🔄 Multi-turn Deep Think Loop: Drives the model through self-play, iterative deduction, and automatic flaw correction via a unified AgentLoop.
• 🎯 System Prompt Management: Inject persistent role definitions and global reasoning context with one click.
• 📊 Context & Intelligence Monitor: Visualize current context utilization and reasoning depth in real time.
• 🌐 Tavily Search Integration: Built-in web search overcomes stale model knowledge with up-to-date information.
• 📁 Local Workspace — full-featured file toolkit for AI workflows:
  • 🔍 search_files: dual-mode smart search (keyword AND-matching + glob patterns like src/**/*.ts)
  • 📄 grep_files: search inside file contents with regex support (like grep -r)
  • 📎 attach_file_to_chat: paste any file (image / PDF / doc / video) directly into the AI chat input
  • 📖 read_file: read files with optional line-range (startLine / endLine) for large files
  • 💾 Auto-restore previously authorized workspace on page load
• 🎮 Sudoku Mini-game: a built-in Sudoku game to keep your brain sharp between prompts.

🧠 Core Architecture

G-Master is more than a shortcut wrapper. It is an engineered closed-loop reasoning and review system:

  B -- AUTO --> C[FLASH Model: Quick Assessment]
  B -- ON --> D[Loop Model: Deep Think]
  C -- Simple answer --> Z((Final Answer))
  C -- Needs depth --> D
