Overview

Fusion is an AI-driven tool designed for streamlining the development and design process across varied teams. It plugs into an existing codebase and design files for a seamless experience, leveraging existing components, styles, and APIs.

It allows users to visually generate and edit content, with the AI building your UI in real-time. Fusion provides an environment suitable for fine-tuning every detail, ensuring precise control in design and alignment with user requirements.

Fusion also facilitates code generation from Figma designs by mapping Figma components to code, hence optimizing workflows that use Figma. A key feature of Fusion is platform integration; the generated UI can be transferred almost anywhere the team needs it, enabling live previews, instant creation of pull requests, or code export for local development.

Moreover, Fusion is built to interact with popular workflow tools like Slack or Jira, contributing to efficiency across the software development lifecycle.

Fusion supports a multitude of frameworks, among them React, Next.js, Vue, Svelte, Angular, which widens the tools usability. It stands out by offering enterprise-grade security and governance features, ensuring SOC 2 Type II compliance and providing granular access controls for user's data privacy and security.
