Hoist protects your data, ensuring it is not trained into a public LLM and allowing you to ensure that client data does not leak between clients.
A workspace is a project, team or client within Hoist. Each workspace can have a collection of knowledge bases (ie data which is made available to the LLM as context) and apps (ie different jobs you want to do with AI). By creating workspaces, you are able to share apps and knowledge bases from your library, while also keeping some apps and knowledge bases private to the workspace.
Hoist provides OpenAI access but it will be rate limited. To use the Hoist API or to increase your chatGPT usage, you will need to provide your own OpenAI API key. This allows Hoist to charge a fixed price, while providing you with unlimited users and ChatGPT usage.
