MEET YOUR CREATIVE WORKSPACE

Your idea.
Every detail, editable.

Meet Form Studio, a fictional class-booking website. Shape the welcome page, build a reusable class card, and connect it to a booking screen. One project, from the first impression to the next tap.

Form Studio is a fictional design concept. This illustrative workspace shows a website and mobile booking screen you could create in LayoutLark.
01 / THE LAYOUT

Set the first impression.

Place the image, find the right headline, and adjust the spacing until the welcome feels right.

02 / THE DETAILS

Give every screen a shared style.

Reuse class cards, colors, and typography. Refine the original and keep linked elements in step.

03 / THE EXPERIENCE

Follow the visitor’s next step.

Connect “Reserve a mat” to the booking screen, then click through the prototype to review the journey.

FROM IDEA TO INTERFACE

Sketch the screen.
Find the flow. Keep building.

01

Start with the screen you need.

Choose a Web or Mobile project. Arrange your first screen on the canvas, or describe it to a connected AI agent.

02

Refine it. Then try the journey.

Adjust the layout, reuse components, and connect screens. Click through your prototype to see what feels right and what needs another pass.

03

Take the next step with your design.

Download images for feedback, save the design file, or export editable starter code to continue in your development tools.

YOUR AI AGENT. YOUR DESIGN TOOLS.

Talk through the idea.
Work on the real design.

MCP connects your AI agent to LayoutLark. It stands for Model Context Protocol: a standard way for AI applications to use tools and read context.

Describe what you want in your agent’s chat. It can read your project, edit screens, and render a preview. You see the changes in the same workspace—and can adjust any element yourself.

“Read my Form Studio project. Add a booking confirmation in the same warm style, and connect ‘Reserve a mat’ to it.”

From a request to editable screens.

Your agent uses LayoutLark’s tools to:

  1. 01
    Read the projectUnderstand the screens and shared styles.
  2. 02
    Make the changeAdd a screen and connect the booking button.
  3. 03
    Render and reviewInspect the preview, then refine the details.

Pick up any detail on the canvas yourself.

A fictional Form Studio example, showing how an MCP conversation can shape a design. The chat and screens above are illustrative.

A useful collaborator, from first draft to handoff.

Start with a clear brief. Then keep the conversation going.

01

Give the first draft a head start.

Ask your agent to read the design guide, create a Web or Mobile project, and build editable screens from your brief.

TRY ASKING“Create a Web project for Form Studio with a welcome page, class schedule, and booking screen. Use warm neutrals and generous spacing.”
02

Refine the details in plain language.

Change copy, spacing, typography, colors, and layout rules. Your agent can read existing elements and make focused edits.

TRY ASKING“Make the class descriptions easier to scan. Shorten the copy, increase the spacing, and give every booking button the same style.”
03

Build a design that stays consistent.

Turn repeated elements into components. Apply shared styles and refine linked instances across your screens.

TRY ASKING“Make this class card a reusable component with beginner and advanced variants. Use the same typography and button style in both.”
04

Work out what happens after the tap.

Connect screens, add overlays or back actions, and organize the flow. Open Preview to try the journey yourself.

TRY ASKING“Connect Reserve a mat to the confirmation screen. Add a back action to return to the class, then arrange the booking flow.”
05

Ask it to look at its own work.

Your agent can render a screen as an image, read layout warnings, and refine the result. Review the preview together.

TRY ASKING“Render the booking screen. Check for clipped text, overflowing elements, and missing images. Fix what you find, then render it again.”
06

Carry the design into development.

Ask for screen images or editable UI starter code for your project’s target. Keep the design and prototype navigation together.

TRY ASKING“Export this Web project as Next.js, React, and Tailwind starter code. Summarize any export warnings and what still needs to be implemented.”

BRING YOUR OWN AGENT

Connect once.
Keep creating together.

Use an AI client that supports remote MCP over Streamable HTTP and OAuth account connections. Setup and tool approval controls vary by client.

Create a free beta account, verify your email, and connect your agent. The ChatGPT marketplace listing is still in preparation.

  1. 01

    Add the MCP server.

    In your agent’s MCP or connector settings, add LayoutLark using the server URL below.

  2. 02

    Connect your account.

    Sign in to LayoutLark and review the requested permissions. Reading uses read access; changing designs also requires edit access.

  3. 03

    Choose a project and give it a brief.

    Ask your agent to list your projects and read the chosen design before editing. Keep the studio open to review the result.

REMOTE MCP SERVER URLhttps://www.layoutlark.com/mcp
Read the agent guide Connection help

Room to experiment.

Agent edits use the same undo history as your own. Automatic checkpoints save the design before edits; named checkpoints let you compare and return to an earlier direction.

You choose the connection.

Connected applications work within your account’s workspace and granted permissions. Review or disconnect them in account settings. Your AI provider’s own data policies apply to content it reads.

You keep the creative control.

Agent-created screens remain editable. Change the type, move an element, or take the design in another direction. Revision checks help prevent an agent from overwriting newer work.

A little more about the connection

Remote MCP is the editing connection. It exposes project, document, library, prototype, render, export, and checkpoint tools. The agent guide covers the recommended read → edit → render workflow.

WebMCP helps browser agents inspect. In supporting browsers, public pages expose product information. The signed-in studio also provides project listings and a bounded view of the open design. These browser tools are read-only; editing uses remote MCP.

Bring your own AI access. LayoutLark doesn’t bundle an AI model or chat subscription. Capabilities and results depend on your connected agent. Code exports are UI starters; you still build the backend and app behavior.

About Model Context Protocol

WHAT’S IN YOUR TOOLKIT

Room for the big picture.
Control over the fine points.

Design, organize, prototype, and revise in one workspace. Explore the controls behind each part of the process.

A canvas for the details that matter.

Build screens from text, shapes, images, frames, and interface controls. Every element stays editable as your idea develops.

Explore the tools
  • Edit text in place. Drag, resize, duplicate, and copy elements between screens.
  • Fine-tune color, borders, corner radius, opacity, fonts, line height, and letter spacing.
  • Group, align, distribute, reorder, reparent, hide, and lock layers, individually or as a selection.

Layouts for screens of every size.

Arrange elements freely or use rows, columns, padding, and gaps. Set sizing rules so the layout responds the way you intend.

Explore the tools
  • Use fixed, fill, or hug sizing, plus constraints. Web projects also support grids.
  • Preview desktop, tablet, and phone presets, or enter your own dimensions.
  • Pan, zoom, snap to guides, and tidy artboards into a grid. Your canvas view is saved with the project.

Design once. Refine everywhere.

Turn a card, button, or navigation into a reusable component. Shared styles help colors, type, and spacing stay consistent.

Explore the tools
  • Create linked instances and named variants. Changes to the master carry through to its instances.
  • Override, reset, or detach an instance when a screen needs something different.
  • Save color, typography, spacing, and appearance styles; update linked elements from one place.

Keep your visual library together.

Bring in the photography, icons, and typography that give your app its character. Reuse assets across the project.

Explore the tools
  • Upload, drag, or paste PNG, JPEG, WebP, and GIF images. Animated GIFs are imported as still images.
  • Replace an image, choose cover or contain, and adjust its focal point and crop zoom.
  • Use built-in recolorable icons and the bundled Manrope and Space Grotesk fonts.

Test the experience one tap at a time.

Link screens into a clickable prototype. Try the menu, open a bottom sheet, and see whether the next step feels natural.

Explore the tools
  • Set a starting screen and add clickable actions or timed transitions.
  • Use overlays, bottom sheets, fades, slides, and back or close actions.
  • Try preview buttons, inputs, and switches. Use Back, Restart, screen selection, and device presets. Form values last only for the preview.

See the journey beyond one screen.

Use the Flow view to map where people go next. Review the main path, alternate routes, and screens that still need a connection.

Explore the tools
  • Draw, edit, or remove screen connections and choose their triggers.
  • Show connections on the canvas, focus on a screen and its neighbors, or automatically organize the flow map.
  • Arrange the map separately from your artboards. Flow positions are saved and changes can be undone.

Try another direction with confidence.

Keep separate projects, automatic saves, and a history of changes. Return to an earlier version when an experiment needs a reset.

Explore the tools
  • Undo and redo your edits and your agent’s edits. Automatic checkpoints preserve the design before agent changes.
  • Save named checkpoints, compare changed elements and properties, and restore an earlier version.
  • Search screens, organize them into sections, and import a saved design document as a new project.

Your designs, in your own workspace.

Your hosted projects belong to your account. Choose which AI applications can connect and what they can access.

Explore the tools
  • Verify your email, sign in and out, and reset your password.
  • Review or disconnect applications and sign out other sessions.
  • Delete your account and its workspace data from account settings. Shared team workspaces and multiplayer editing are not available yet.

A FEW PRACTICAL DETAILS

Good questions.
Clear answers.

Is LayoutLark free to use?

Yes. The current workspace is free to use, including visual editing, components, shared styles, prototypes, MCP design tools, project history, and exports. You do not need a paid LayoutLark subscription to use these features. LayoutLark is in beta. No credit card is required.

Does using AI or exporting code cost extra?

LayoutLark does not charge an additional fee to connect an agent or export your designs. Bring your own compatible AI client and model access; that provider may charge separately for its subscription or usage. Hosting and running the app you build from exported code are also separate services.

Who is it for?

Founders exploring a product idea, designers shaping a client concept, and developers planning an interface before implementation. Start with a single screen or build out a connected flow; you can edit directly on the canvas without an AI connection.

How does the AI connection work?

Add LayoutLark’s remote MCP URL in a compatible AI client, then connect your account through OAuth. Ask the agent to read your chosen project, make a change, and render the result. You and the agent work on the same editable design. The client needs remote MCP and OAuth support; setup varies. The ChatGPT marketplace listing is still in preparation.

Can I use LayoutLark without AI?

Yes. You can create screens, edit components, connect prototypes, manage projects, and export directly in the visual editor. An AI connection is optional. If you do connect an agent, its edits use the same undo history and checkpoint recovery as the rest of your design work.

What do I still need to build after exporting?

Exports give you an editable interface and prototype navigation. You add the backend, APIs, authentication, validation, and application behavior, then test before release. LayoutLark does not deploy or publish the exported app. External image URLs remain remote references. Hosted download links expire after 15 minutes, and anyone holding a link can download until then.

Should I choose a Web or Mobile project?

Choose Web for Next.js, React, and Tailwind CSS output. Choose Mobile for Expo, React Native, and NativeWind output. A phone-sized Web screen is still a web design. Layouts follow the sizing rules and constraints you set; mobile prototypes preview in the browser, and native output needs testing on actual devices.

Can my team work in the same project?

Each hosted account currently has its own private workspace. You and your connected agent can edit the same design. Shared team workspaces and live multiplayer editing are not available yet.

Can I create an account today?

Yes. Create a free beta account, verify your email, and open your own design workspace. No credit card is required.
