Persistent AI sandboxes

Give an agent a task. Open the result.

Millyard gives AI agents a real place to work — a sandbox with files, a shell, and a schedule that's still there tomorrow. Ask for a working app, not a wall of text.

A sandbox that doesn't forget

Most agent runs are disposable: the work happens somewhere temporary, then it's gone. A Millyard sandbox is durable — it sleeps between sessions and picks up where it left off.

Files that persist

Work an agent does today is still on disk next week. Build on Tuesday, revise on Friday, come back to it next month.

Real tools

Agents get a shell and a filesystem, not a text box. They install what they need, run what they build, and keep the results.

One sandbox per project

A project's files, jobs, and history live in one place. No hunting through transcripts for where the work went.

From request to running app

Ask for a small chore-planning app for your household. The agent asks a few questions, builds it in the project's sandbox, and hands back something you can open — a working app, not a code listing to figure out yourself.

Describe it in a sentence

"Make a small planning app for weekly chores — some repeat, some are one-off, and big ones take a few sessions." That's the whole spec.

Built where you can see it

The agent works in the sandbox in the open — you can watch the steps, answer its questions, and course-correct midway.

Yours to keep

The result stays in the sandbox. Ask for changes next week and the agent picks up the same files, not a blank slate.

Work on a schedule

"Every Friday at 3pm, send us suggestions on what to tackle this weekend." One sentence sets it up. Agents run on a schedule and report back in the conversation — reminders, checks, and recurring jobs written in plain language.
