# AI Caption Generator
Public demo for generating captions from images and short videos.
## Secrets (recommended)
Set these in your Hugging Face Space **Settings → Secrets**:
- `OPENROUTER_API_KEY` (required) – the app enforces AI caption polishing.
- `BLIP_OFFLINE` (optional) – set to `1` only if you have a preloaded HF cache.
## Notes
- First run will download the BLIP model from Hugging Face.
- Video captioning uses OpenCV to sample frames.
