Use the interactive tool above, then read the setup and usage notes below.

IMAGE–TEXT SIMILARITY · RUNS ON YOUR DEVICE

Type several captions and see how well each one matches an image. MobileCLIP-S0 maps text and image into one embedding space; the cosine similarity is the match score.

## Questions

[More tools](/blog/apple-ai-browser-tools)**What does zero-shot mean?**

The model was never trained on your labels. It compares the image embedding with a text embedding of each label, so any phrase can be a class.

**How do I write good labels?**

Use short, concrete noun phrases and keep the template on. Add a catch-all like “something else” to see whether the model is unsure.

**Is this MobileCLIP2?**

No. The browser tool uses MobileCLIP-S0, the first-generation model ported to Transformers.js. MobileCLIP2 runs locally with Python; see the guide.

**Is my image uploaded?**

No. Embedding happens in a Web Worker in your browser. Only the model files are downloaded from Hugging Face on first use.
