Internal tools often begin as a spreadsheet, a checklist, or a prompt someone runs every week. The process works, but the interface does not: people copy values between tabs, remember status in their heads, and repeat the same setup each time. Construct can turn that repeated process into a small private app that lives inside the same workspace as the files and agent doing the work.

This is not a one-click path to a public SaaS product. A Construct workspace app is a focused internal interface for one workspace. You describe the job, the agent writes the app, checks that it builds, opens it in the desktop, and keeps the source available for inspection and later changes.

Start with the repeated process

The best request describes the work rather than prescribing a software architecture. For example:

“Build a research request tracker with an owner, priority, status, and link to the finished report.”

“Turn this recurring launch checklist into an app the team can update.”

“Create a dashboard for the JSON reports stored in this workspace.”

“Build an intake form for customer-review requests and keep the queue in one place.”

Construct can start from a list, form, dashboard, or blank interface. The agent creates the app package, writes the React and TypeScript source, declares the capabilities it needs, and validates the result. A successful build opens directly in the Construct web desktop instead of sending you to a separate hosting project.

The request still matters. “Build an operations dashboard” leaves important choices unresolved. “Show open research requests, let an operator assign an owner, and mark the linked report as reviewed” gives the agent a bounded workflow and a clear way to tell whether the app is useful.

The app lives beside the work

A workspace app is not a hidden artifact. Its source lives under an Apps// folder in Files, where it can be inspected and edited. After a successful build, the app appears as a private workspace install that can be reopened from the desktop, Launchpad, or Spotlight.

The app's durable state is kept separately under AppData//. That separation is important: changing the interface should not require overwriting the records the app already manages. Rebuilding can update the code while existing app data remains in the workspace and continues to count against the normal workspace storage quota.

This model also makes the surrounding agent useful after launch. The same workspace contains the source, relevant files, conversations, and diagnostics. If the interface needs another field or a runtime error appears, the next task can start with the actual app rather than a screenshot and a vague bug report.

What a workspace app can do

The current runtime is intentionally narrower than a general web-hosting platform. That keeps an internal tool close to its workspace purpose.

The app UI receives a small Construct SDK for workspace files, app-scoped storage, notifications, window controls, and explicitly permitted calls. It does not inherit every tool available to the agent that authored it. The agent can use broader execution surfaces while building, but the finished interface runs with its own narrower contract.

Permissions are part of the design

An internal tool should not gain broad access simply because it was generated inside a trusted workspace. A workspace app declares the native capabilities, connected apps, and network origins it intends to use. Calls outside those allowlists are denied at runtime.

The platform also rechecks current workspace membership and permissions when the app makes a gateway call. File operations remain subject to the user's workspace access, and an app cannot use its file access to rewrite another app's package. Direct network access is limited to exact HTTPS origins rather than wildcard domains.

For a request tracker that only reads and writes workspace files, that can mean declaring Files access and nothing else. A tool that posts an approved record to a connected service needs that specific app target as well. The useful default is the smallest permission set that completes the job.

Validation creates a build, not a guarantee

Before launch, Construct checks the package...
