Whether you’re an experienced developer or someone with no coding background, Layout leverages AI to remove the traditional barriers to building software and enables users to bring their ideas to life faster and more easily. Our mission is to democratize software creation by providing AI-powered tools that transform ideas into functional prototypes in minutes—empowering innovators of all skill levels to experiment, build, and launch their ideas.

Builder.io Fusion is a cutting-edge visual development platform designed to help teams build web apps and UIs from Figma designs, existing repos, or scratch, accelerating the path from idea to production. It seamlessly integrates with any codebase and leverages your design tokens and components to generate clean, consistent code that matches your development standards. The platform allows both developers and non-developers to visually modify generated experiences with drag-and-drop functionality and fine-tune styling at a granular level. Fusion also prompts with backend context to create fully interactive designs and supports publishing through API for flexible deployment. Enterprise features include granular roles and permissions, customizable workflows, and the ability to bring your own LLM API key without training on your data, prioritizing privacy and control. Major brands such as Everlane, Zapier, and J.Crew have used Fusion to boost development efficiency by 20%, shorten time to market, and free engineering capacity. Fusion’s security compliance with SOC 2 Type II ensures robust protection for enterprise workflows. The platform empowers cross-functional teams to collaborate and innovate faster while maintaining high standards of code quality.

Paper is a collaborative design platform that connects design, development, and AI-driven workflows within a single digital canvas. Built on open web standards, the platform enables teams to create visual designs that translate directly into functional HTML and CSS code. This approach reduces the friction between designers and developers by ensuring that visual work and production code stay synchronized. Paper integrates with development environments, APIs, and AI agents so that components, styles, and design tokens can be automatically updated across the design canvas and the codebase. Teams can bring real data, content, and application context into the design environment, allowing them to build interfaces using actual information rather than placeholder content. The platform supports collaboration between humans and AI agents that can assist with tasks such as layout adjustments, responsive variants, and repetitive design work. Paper Desktop expands this capability by connecting the canvas to apps, repositories, and development tools used throughout the workflow. Designers and developers can iterate quickly while maintaining a continuous loop between design and production code. This unified system helps reduce translation errors and keeps projects aligned across teams. By merging design, code, and AI assistance into one environment, Paper enables a more fluid product development workflow.

Fusion serves as an AI-driven development platform that seamlessly merges design, product management, and engineering processes by linking directly to your codebase, design system, and tools. This innovative platform empowers teams to visually create and modify responsive, production-ready user interfaces by utilizing existing repositories, design tokens, and APIs; users can easily import Figma designs, connect their GitHub or other Git providers, and issue changes using natural language, which the system converts into pull requests or live previews. It features real-time canvas editing with exceptional pixel precision, comprehends your components, styles, and backend architecture, and allows any team member—including designers, project managers, and developers—to construct features, prototypes, and fully interactive experiences without the need to manually code each element. With built-in workflow integration, users can trigger builds through Slack mentions, Jira tickets, or discussions around design, while also tracking progress, reviewing generated branches, and merging into standard CI/CD pipelines. This streamlined approach not only enhances collaboration but also increases efficiency across teams, making the development process more intuitive and accessible for everyone involved.

Mentor by Skippr is a real-time AI product critique platform designed to help teams improve UX, accessibility, design, and content before launch. The tool works directly in the browser so builders can receive feedback while they are creating or reviewing a product. Mentor analyzes websites and interfaces through AI product experts that provide actionable recommendations, go/no-go guidance, annotations, reports, and workflow-ready issues. Its expert agents include a Head of Design for high-level strategy, a Product Manager for goals and priorities, a Product Designer for UI and visual details, a Content Strategist for copy and narrative, and an Accessibility Lead for usability gaps. Teams can use Mentor to check spacing, typography, hierarchy, imagery, contrast, text sizing, touch targets, copy clarity, SEO relevance, and product alignment. Feedback can be converted into tasks through workflow integrations with Linear and Jira. Mentor also creates customizable online and PDF reports that can be shared with stakeholders. Its MCP integration sends product feedback to coding agents such as Claude, Cursor, and Copilot so issues can move from critique to implementation faster. By combining AI design review, accessibility checks, content analysis, reports, tickets, and coding-agent workflows, Mentor helps teams ship better products with fewer post-launch revisions.

Pencil.dev is an innovative design-in-code platform that utilizes AI to seamlessly integrate visual interface design within development environments such as Cursor, VS Code, and various other IDEs, allowing designers and developers to collaborate without the need for tool handoffs. Centered around an agent-driven Model Context Protocol (MCP) canvas and an accessible design format embedded in your codebase, Pencil enables users to create, refine, and produce pixel-perfect UI screens with the aid of AI, all while maintaining version control in Git alongside their source code, which facilitates branches, merges, and rollbacks akin to traditional coding practices. By incorporating a Figma-like canvas directly into the IDE, it significantly reduces the hassle of switching between different tools, supports the import of frames and assets from Figma while preserving vectors and styles, and allows for manipulation of design elements through intuitive editing panels, layers, and CSS-like properties. Furthermore, AI models assist in the simultaneous generation of screens, flows, and components, enhancing productivity and creativity in the design process. This integration fosters a more cohesive workflow, making it easier for teams to innovate and iterate on their projects efficiently.
