gemma-media-study：用本地 AI 把视频音频变成学习资料

🧠 gemma-media-study - Master videos with local AI tools

gemma-media-study turns video and audio files into learning resources. It runs entirely on your Windows computer. It uses artificial intelligence to transcribe speech, analyze scenes, and answer your questions about the content. You keep full control over your data since the application processes files on your local drive.

🛠️ What This App Does

This tool assists you with deep study sessions. You can import YouTube links or local video files. The application generates precise subtitles using the built-in Whisper engine. It then breaks down the video frame by frame. You can chat with a built-in AI tutor based on Gemma 4 to clarify complex topics or summarize long lectures.

• Transcribe audio to text with high accuracy.
• Ask questions about specific video segments.
• Review content with frame-by-frame snapshots.
• Benefit from local processing for privacy.
• Receive automatic software updates.

💻 System Requirements

Your computer must meet these basic standards to run the application well.

• Windows 10 or Windows 11.
• At least 8GB of RAM.
• 10GB of available disk space for the AI models.
• A stable internet connection for the first-time setup and downloading media.
• Ollama installed on your system (the installer handles this step for you).

📥 Download and Install

Follow these steps to set up the software on your machine.

1. Visit the official releases page.
2. Look for the file ending in .msi or .exe under the latest release.
3. Click the link to download the installer to your computer.
4. Run the downloaded file. Windows might show a security prompt because this is a desktop app. Click "More info" and then "Run anyway" if the system protects your machine.
5. Follow the on-screen instructions to finish the installation.
6. The application launcher will appear on your desktop once the process ends.

🚀 Getting Started

The first time you open the app, it needs to configure the AI brain. This takes a few minutes depending on your internet speed.

1. Open the app from your desktop shortcut.
2. Wait for the initial model download to finish. This gives the app the intelligence it needs to chat.
3. Paste a YouTube URL into the input field or click "Upload File" to select a video or audio file from your computer.
4. Wait for the engine to transcribe the audio. You will see a progress bar near the bottom of the window.
5. Click the "Analyze" button once the text appears.
6. Type your questions in the chat window on the side. The AI tutor provides answers based on the transcript and video content.

🔍 How to Analyze Content

You get more out of your media when you use the frame-by-frame feature. Select any part of the video timeline to view the exact frame. The AI labels the objects and actions in that moment. You can ask for a summary of a specific chapter by highlighting the text in the transcript pane and clicking "Ask about this selection."

⚙️ Settings and Management

You can change how the app handles your files in the settings menu.

• Model Folder: Pick where the app saves the large AI model files. Use a drive with plenty of space.
• Data Storage: Set where your study projects live on your hard drive.
• Language Settings: Adjust the target language for transcriptions if you need to study content in another language.
• Update Frequency: Toggle automatic updates to ensure you always have the most stable version of the app.

🔧 Frequently Asked Questions

Does the app send my videos to a server?

No. All processing happens on your computer. Your videos and chats never leave your local machine.

Why does the app use so much disk space?

The app downloads the Gemma 4 AI model. These models are large files that allow the app to function without an internet connection once the download completes.

The app runs slowly. What can I do?

Close other programs while using the app. High-definition video processing requires significant memory. If you have many applications open, the AI might struggle to give fast responses.

Can I use the app offline?

Yes. Once you complete the first-time setup, you do not need the internet to process files or ask questions.

How do I update to a newer version?

The app checks for updates automatically. A notification will appear in the top-right corner when a new version is ready. Click "Update" to refresh your installation.

🛡️ Privacy and Safety

This project follows a local-first philosophy. We do not track your activity, gather your analytics, or store your study data. The code runs inside a secure shell on your Windows environment. You own all the files produced by the app. If you delete a project folder, the app and all associated data vanish from your system completely. This ensures total control over your digital workspace.
