Bring scattered AI use under one platform you control.
Assist turns your team's one-off prompts, tools, and workflows into shared company infrastructure owned by your org.
Software Is Something You Build Now
Ever wished for a tool that does exactly what you need and nothing else? That's a sandcastle.
A script to score inbound leads. A dashboard for one team. A workflow that matches how you actually work.
AI has collapsed the cost of building these. You don't need engineers anymore.
But when everyone can build, something else becomes the constraint.
Software That Solves Your Problem and Nothing Else
Sandcastles are quick, purpose-built apps that solve a specific problem for a small group of people. They don't need to serve millions of users. They don't need to be polished. They just need to work.
A tool to manage your team's hiring pipeline. An app that scores leads the way your business actually thinks about them. A dashboard that pulls together exactly the data your ops team checks every morning.
Coders have been building these for decades. Now everyone can.

More Than a Simple App
Every sandcastle on Assist is a full application with agentic workflows built in. They don't just display data. They act on it.
Built-in Agents
Every sandcastle can have AI agents attached that reason, decide, and take action on behalf of your team.
Agentic Workflows
Chain together multi-step processes that run on their own. Data collection, decision-making, execution.
External Connections
Hook your sandcastles into the systems you already use. Databases, APIs, SaaS tools, internal services.
When Building Gets Easy, Control Gets Hard
Security
Uncontrolled agents accessing production data.
Governance
No visibility into who built what, and how it runs.
Compliance
Audit trails, permissions, data boundaries.
The problem isn't building sandcastles.
It's governing what gets built.

Quick answers about Assist, sandcastles, pricing, and who can build.
Stop Buying Software. Start Building It.
Assist gives your team the power to build exactly what they need with the controls your org requires.
If you know how to code, you've probably built what we call sandcastles. Quick tools to solve a specific problem. A script, a dashboard, a workflow. Disposable, personal, and powerful.
AI means everyone can build sandcastles now. That changes everything about how software works.
Assist is the platform that makes this real for your whole organization.
