+Welcome! This interactive demo lets you denoise and enhance audio files using ai-coustics models.
+
+You can choose from three models, each designed for different needs:
+- [Quail](https://ai-coustics.com/2025/07/02/meet-quail-the-most-advanced-real-time-speech-enhancement-model/): Our smallest, most lightweight model, ideal for real-time voice isolation. Quail is available for free here and in our [SDK](https://docs.ai-coustics.com/sdk/overview).
+- [Finch](https://ai-coustics.com/2025/06/12/introducing-finch-2-the-new-aicoustics-model-for-studio-quality-speech/): A larger model specialized in voice isolation and background noise removal. Available via our [API](https://docs.ai-coustics.com/api-reference/quickstart) (API key required).
+- [Lark](https://ai-coustics.com/2025/07/29/lark-2-next-generation-reconstructive-speech-enhancement/): Our most advanced, universal speech enhancement model, capable of restoring audio artifacts such as distortion. Also available via our [API](https://docs.ai-coustics.com/api-reference/quickstart) (API key required).
+
+You get 120 minutes of free API trial usage. Learn more about our technology and capabilities at [ai-coustics](https://ai-coustics.com/).
 
 **How to Use:**
 
-Upload or record a (noisy) speech sample to enhance its quality. You can optionally add background noise to the input. To generate new enhanced audio, you'll need an API key. Alternatively, you can preview some enhancement results instantly by selecting one of the preprocessed examples below — no API key required.
+Upload or record a noisy speech sample to enhance its quality. Optionally, add background noise to the input. Adjust the enhancement level to control enhancement you want to apply. You can try Quail for free; to use Lark 2 and Finch, you'll need an API key. Alternatively, preview enhancement results instantly by selecting one of the preprocessed examples below.
