Hyperparam Desktop App

The Hyperparam Desktop app is the same application as hyperparam.app running as a native desktop app. The UI, features, and AI capabilities are identical. The desktop app adds connectors for private cloud storage and lets you bring your own AI model API keys.

Why Use the Desktop App?

  • Private cloud storage: browse and open files directly from AWS S3, Google Cloud Storage, and Azure Blob Storage using your existing credentials
  • Custom AI providers: use your own Anthropic or OpenAI API keys instead of the Hyperparam-managed providers
  • Local file access: open files from your local filesystem without uploading them

Installation

Download the latest release from hyperparam.app/desktop:

After installing, sign in with your Hyperparam account to get started.

Storage

The desktop app intercepts requests to cloud storage URLs and authenticates them using credentials from your local environment. No credentials are sent to Hyperparam servers.

AWS S3

The desktop app uses the standard AWS SDK credential chain, the same one used by the AWS CLI and SDKs. This includes:

  • Environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
  • ~/.aws/credentials and ~/.aws/config
  • IAM instance roles and SSO sessions

Open any s3://bucket/path URL in Hyperparam to browse or stream files directly.

In Settings, under AWS, you can optionally select a named profile to override the default credential chain.

Google Cloud Storage

The desktop app uses Application Default Credentials (ADC). Authenticate with:

gcloud auth application-default login

Or set the GOOGLE_APPLICATION_CREDENTIALS environment variable to a service account key file.

Open any https://storage.googleapis.com/bucket/... URL to access private GCS objects.

Azure Blob Storage

The desktop app authenticates via the Azure CLI. Run:

az login

Then go to Settings, open the Azure tab, enable Azure Blob Storage, and optionally enter a Subscription ID to override the CLI default.

This uses DefaultAzureCredential, which also picks up environment variables (AZURE_CLIENT_ID, AZURE_TENANT_ID, etc.) and managed identity in Azure-hosted environments.

Models

By default the desktop app uses Hyperparam-managed AI providers (no API key required). In Settings, under Models, switch to "Use custom providers" to supply your own keys:

ProviderFieldDefault endpoint
AnthropicAPI Key + Endpointhttps://api.anthropic.com
OpenAIAPI Key + Endpointhttps://api.openai.com/v1

The endpoint field can be left blank or overridden to point at a compatible proxy or local inference server.

To enable or disable individual AI tools in the chat interface, open Settings and go to the Tools tab.

Offline Mode

If the desktop app cannot reach hyperparam.app at launch, it shows an offline page. Reconnect to the internet and relaunch to resume.
