See how your app fits together.

Bring the screens into view

As you build with AI, layouts, wording and behaviour can drift between screens. Checking each one as you go only tells you part of the story. You also need to see whether they make sense together.

Seamling is a downloadable kit your coding agent sets up inside your project. For an existing app, it brings the screens it can safely connect into a local gallery, organised around the people using it and what they're trying to do.

Start with the person, not a list of screens

Ana follows worker welfare. Maria receives the welfare contact. An agency administrator looks after access and payment. They're using the same app, but each needs something different from it.

These are your personas: the people you're building for, their goals and the circumstances that shape what they need. Your agent drafts them from what you know about your app, keeping questions visible for you to resolve.

See the work from each person's side

Choose a person in the gallery to focus on their moments. Ana needs to begin her shift and follow up a missed reply. Maria needs to receive and answer the contact. Looking at both sides helps you ask whether those journeys actually meet.

Return to the overview to compare the parts of the app. The gallery separates available previews from work that hasn't been connected or created.

Give your agent something specific to work on

Compare the screens you have connected: do the same actions have the same names? Does the next step carry the right person and information? Is a missing screen an app gap, or has it simply not been attached to the gallery yet?

When you find something to change, ask your agent to trace the affected rules and neighbouring moments, update the relevant records and preview, then show you the result.

Starting with an idea

Your agent can map the people and journeys from your vision, then draft briefs, logic and previews as you work through the design. You don't need a finished app to begin.
