+## Demo of SimCSE 
+Several demos are available for people to play with our pre-trained SimCSE.
+
+### Flask Demo
+<div align="center">
+<img src="../figure/demo.gif" width="750">
+</div>
+
+We provide a simple Web demo based on [flask](https://github.com/pallets/flask) to show how SimCSE can be directly used for information retrieval. The code is based on [DensePhrases](https://arxiv.org/abs/2012.12624)' [repo](https://github.com/princeton-nlp/DensePhrases) and [demo](http://densephrases.korea.ac.kr) (a lot of thanks to the authors of DensePhrases). To run this flask demo locally, make sure the SimCSE inference interfaces are setup:
+```bash
+git clone https://github.com/princeton-nlp/SimCSE
+cd SimCSE
+python setup.py develop
+```
+Then you can use `run_demo_example.sh` to launch the demo. As a default setting, we build the index for 1000 sentences sampled from STS-B dataset. Feel free to build the index of your own corpora. You can also install [faiss](https://github.com/facebookresearch/faiss) to speed up the retrieval process.
+
+### Gradio Demo
+[AK391](https://github.com/AK391) has provided a [Gradio Web Demo](https://gradio.app/g/AK391/SimCSE) of SimCSE to show how the pre-trained models can predict the semantic similarity between two sentences.

+        SimCSE is a novel framework for contrastive learning of sentence embeddings. This demo shows how our pre-trained sentence embeddings can be directly applied to sentence retrieval tasks. You can type any natural language sentences and click the search button to see which sentences in the example database are semantically similar to the provided sentence. Here are some details about this demo:

+              <li>Retrieved sentences are coming from STS-Benchmark dataset</li>
+              <li>Two hyperparameters can be adjusted: (1) Top-K: the maximum number of sentences to be displayed (2) Threshold: the minimum similarity score for a sentence to be retrieved </li>
+              <li>We use Faiss to accelerate the sentence retrieval process</li>
