Getting started

No. You describe what you want in plain language and the Builder makes every technical decision. Nothing in these docs assumes you can read code.
No. Restart runs entirely in your browser at app.restart.new.
No. Restart asks you to create an account before anything else: name, email, and password, or Continue with Google. An email sign-up is confirmed with a six-digit code (or the link in the same email) before you can sign in. See the Quickstart.
A few minutes. The whole loop — idea, conversation, build, publish — takes about twenty minutes the first time.

What Restart builds

A working web product: real pages, real copy written for your idea, and a design chosen to suit it. Good enough to show someone the same day.
First versions use sample data rather than a live backend — no customer accounts and no services wired in. The one exception is payments: with Stripe connected, the Builder can create a real payment link in your own Stripe account and put it on your site.
No. Restart builds web products. If your idea is a native app, the coach will say so and steer you toward the web version that proves it — a landing page with a waitlist, or a clickable demo.
You can browse everything the Builder writes under Files, and edit your business plan there. The app itself changes only by asking the Builder in the conversation.
Not yet. Code export is not available; your files are browsable in the app.

Agents

Two that you talk to: the coach, which follows you through the app and sharpens your ideas, and the Builder, which builds in a workspace. Daily task suggestions and automations are Restart working in the background, not extra agents to manage.
It genuinely cannot see your account, credits, or plan. Those live in Settings and on the Usage page.
Only when a choice would genuinely change what gets built. It never asks about technical decisions — those are its own.
No, by design. Restart sends or posts only when you ask in the moment, and automations never send anything — they leave drafts for your okay. See App permissions.

Publishing

A name you choose plus .restart.new — for example kilnwork.restart.new. You pick it on your first publish. You can rename it later under Manage domain on Home.
Yes. Open Manage domain on Home and connect a domain you already own under Your own domain; the dialog shows the records to add at your provider. Buying a new domain inside Restart is separate and may not be switched on for your account.
No. A published site is a snapshot and changes only when you publish again — and every publish waits for your explicit approval. That is deliberate: you can keep building without changing what visitors see.
Yes. Open Manage domain on Home, select Edit address, and save the new name. The old address stops working the moment you save, and it cannot be claimed again.
There is no unpublish button in the app. Deleting the workspace takes its site down permanently — or contact support if you need a site taken down without losing the workspace.

Running your company

Restart writes them from your business plan and what has actually happened in your company. They start after your first build. See Daily tasks.
Dozens — Gmail, Google Calendar, Stripe, Notion, Slack, HubSpot, and more, listed on the Apps page. Connect one and ask the coach to work it in plain language. See Connect your apps.
Yes — yourhandle@mail.skarmy.ai, with a real inbox in the app. See Your company inbox.
No. Credits are spent on building. Tasks, the coach, the inbox, and automation runs are covered by fair-use limits instead.

Credits and plans

Three things: the Builder working, the machine running your app while your session is awake, and each publish.
Daily and monthly allowances do not roll over. Purchased top-up credits never expire.
Work pauses. Nothing is deleted — your workspaces, files, and published site are untouched. Add credits or wait for the daily allowance to refill at midnight UTC.
Pro is $99 a month and Autonomous starts at $399 a month, with yearly billing at the equivalent of nine months; a Custom plan is priced on a call. The Billing page in the app is always authoritative. See Plans.
Yes. Set a Monthly spend limit on the Usage page. Usage pauses for the month once spend reaches the cap.

Teams and access

Yes, if they already have a Restart account. The owner or an admin adds a teammate by email under Settings → Members (and on the People page); the person becomes a member right away and gets an email. An email without a Restart account is refused, so ask them to sign up first. How many people a company can hold depends on the plan; the Billing page is authoritative.
No. Restart does not currently offer a public API or API keys.
Up to ten, switched from the top of the sidebar. Each has its own workspaces, tasks, inbox, and apps.
