Get started

Build your first app

Start with one clear prompt, review the working preview, make a focused change, and publish when the result is ready.

This guide takes you from an idea to a live first app. You will build one focused page for a fictional coffee roaster, review it in Preview, make one improvement, and publish it.

Mythos is currently in private, owner-only access. This guide assumes that your account is already authorized. See Signing in and accounts.

Before you start

Have three things ready:

  • The outcome you want, such as a landing page, portfolio, or dashboard.
  • The content or sections that matter most.
  • Enough balance for the action. Credits and usage explains the current fixed prices and refund behavior.

You do not need a finished specification. A clear audience, purpose, and visual direction are enough for a useful first result.

Build the first version

Start a project

Open the dashboard and use the main composer. For this guide, enter:

Build a one-page website for North Slope, a neighborhood coffee roaster.
Include a hero, featured beans, a short wholesale section, opening hours,
and contact details. Use a warm, minimal visual style with generous spacing.

This prompt names the business, the page structure, and the desired feel while leaving room for Mythos to make sensible design decisions.

Choose Build or Plan

Choose Build when the brief is ready and you want to go straight to a result. Choose Plan when you want Mythos to ask focused questions and prepare an editable plan before it changes the project. See Plan mode.

Follow the progress

Mythos shows progress in the conversation while it creates and checks the app. Keep the workspace open; there is no need to resend the prompt while the run is active.

Review the preview

When the result card appears, inspect the page as a visitor would. Check the headline, section order, links, and the layout at more than one viewport size. A delivered result becomes the current project version.

Ask for one improvement

You do not need to repeat the original brief. Describe the exact section and the change you want:

In the featured beans section, add three roast cards with a short tasting note
and price for each. Keep the existing warm palette and spacing.

Review the updated preview when the edit finishes. If the change moved in the wrong direction, use Version history to inspect an earlier version or revert safely.

Focused follow-ups are easier to verify. Ask for one coherent outcome at a time, then look at the result before sending the next request.

Publish when it is ready

Choose Publish in the workspace, review the project name and URL, and confirm. Publishing uses the latest delivered version; later workspace edits do not change the live site until you publish again.

A published site is public on the internet. Remove private information and test the visible content before you confirm.
