This tool uses a powerful AI model (ViT-GPT2) running entirely in your browser to analyze images and generate natural language descriptions. Since the AI runs locally, your photos are never sent to a server.
How to Use Image Caption Generator
1. Upload an image
2. Wait for the AI model to load (first time only)
3. The AI will analyze the image and generate a caption automatically
Common Use Cases
- Generating alt text for accessibility
- Creating metadata for image libraries
- Social media content creation
- Testing AI computer vision capabilities
Frequently Asked Questions
Is my image uploaded?
No. The AI model runs directly in your browser using WebAssembly. Your image never leaves your device.
Why is it slow the first time?
The browser needs to download the AI model (~300MB) once. Subsequent uses will be much faster.
