Assist is a platform where teams can build, host, and deploy internal AI software and agents in one place — giving companies a safe, controlled environment to standardize workflows and improve operations.

What are sandcastles?

Sandcastles are purpose-built internal apps created by non-technical teams on the Assist platform. They allow employees to build custom tools and workflows without engineering resources.

How much does Assist cost?

Assist uses pay-as-you-go pricing: provider costs + 5%, $0.17 per 1k tool calls, with no seat fees. Enterprise custom pricing is also available.

Do we need engineers to use Assist?

No. Assist is designed for non-technical teams to build and deploy AI tools. Engineers can use it too, but it doesn't require engineering resources to get started.

SSO, Multi-Provider AI, and Sandcastle State

Single Sign-On (SSO)

Workspaces can now require members to sign in through their company's identity provider.

Any OIDC provider -- Works with Okta, Azure AD, Google Workspace, and any OIDC-compatible identity provider
SCIM directory sync -- Automatically provision and deprovision user accounts when people join or leave your organization
Workspace enforcement -- Require all members to authenticate through SSO so no one bypasses your identity policies

More AI Models

Assist now supports models from additional providers, giving you more flexibility in how your tools and agents run.

New providers -- Google Gemini, Cerebras, Perplexity, and OpenAI models are now available alongside Anthropic
Choose per workflow -- Select the best model for each agent or tool based on speed, cost, or capability

Sandcastle Persistent State

AI-built apps (sandcastles) can now store and retrieve data that persists between sessions.

Read and write data -- Sandcastle apps can save records, update them, and query them with pagination
Survives sessions -- Data persists across browser refreshes and between different users

Slack Long Message Handling

AI responses in Slack are no longer truncated when they exceed the message size limit. Long responses are automatically split into multiple messages so nothing is lost.

Security Improvements

DNS rebinding protection for all outbound requests
Workspace deactivation now enforced across Slack, MCP, and all API endpoints
