How it works

From idea to tested prototype in four steps

A prototyping workflow designed for speed, real feedback, and confident decisions

Step 1

Describe your idea

Just describe what you want to prototype — a flow, a feature, or a full product concept. No design experience required, just your idea.

Step 2

Get a clickable prototype

Greta generates a fully interactive prototype with real screens, navigation, and flows — ready to share within minutes.

Step 3

Test with real people

Share a link with users, clients, or your team. Collect real reactions before writing a single line of production code.

Step 4

Iterate and ship with confidence

Update the prototype instantly based on what you learn. Ship only the version you know works — not the one you hoped would.

Core Capabilities

Everything you need to move fast

Every tool you need to go from idea to live product — build, test, iterate, and grow with Greta.

Prompt to Prototype

Describe any product idea in plain language and get a fully navigable, interactive prototype in minutes.

Iterate in Real Time

Update layouts, flows, and copy instantly as you learn. Feedback loops now take minutes, not days.

Test With Real Users

Present live, working prototypes to clients or teams instead of slides, wireframes, or long explanations.

Experiment without risk

Try new features, flows, or ideas freely, without affecting your main product or roadmap.

Everything you need to know before you start prototyping with Greta.

No. Just describe what you want to prototype. Greta handles the design and structure — you bring the idea.

Update instantly and re-share the same link. Feedback recipients always see your latest version without any friction.

Build Something Real

If you can describe it, you can build it.
