-OptiNiSt(Optical Neuroimage Studio) is a GUI based workflow pipeline tools for processing two-photon calcium imaging data.
+**Araya-OptiNiSt Cloud** allows researchers to process and visualize their calcium imaging data entirely online. It was built by [Araya Inc.](https://www.araya.org/en/) on top of [OptiNiSt](https://github.com/oist/optinist), an open-source calcium imaging pipeline tool originally developed in collaboration with [OIST](https://www.oist.jp/).
 
-OptiNiSt helps researchers try multiple data analysis methods, visualize the results, and construct the data analysis pipelines easily and quickly on GUI. OptiNiSt's data-saving format follows NWB standards.
+We believe in open, reproducible science and in making it easy to share results between labs. Araya-OptiNiSt Cloud is built around these principles:
 
-OptiNiSt also supports reproducibility of scientific research, standardization of analysis protocols, and developments of novel analysis tools as plug-in.
+- **Public Data Sharing**: Publish your experiments to the [public page](https://www.araya-optinist.com/public), where anyone can view your results and reproduce your workflows without needing an account.
+- **Cloud Computing**: Run analysis pipelines on cloud infrastructure without managing local hardware.
+- **Cloud Storage**: Store your data securely in the cloud with Amazon S3-backed storage and on-demand synchronization.
+
+### Plans
+
+Plans are available to suit different needs, from individual researchers to large labs.
+
+- **Free** -- Shared compute resources with limited storage.
+- **Premium** -- Dedicated compute resources with expanded storage.
+- **Custom** -- Any size of compute (CPU or GPU) and storage. Additional analysis methods and plots can be added on request.
+
+See the [Subscription page](https://www.araya-optinist.com/subscription) for full details.
