Matter
AI development companion for product teams
Skip the throwaway prototypes. Build what lasts.

Test new ideas faster – no coding required
Most prototyping tools create beautiful mockups that developers have to rebuild from scratch. Matter is different! It works directly in your codebase, so your prototype becomes your foundation.
Build a functional flow
Build quick prototypes and test business logic with the existing codebase.
Enhance the user experience
Explore and polish your prototypes visually – all without leaving your existing codebase.
Dive into new technologies
Experiment with 3D, interactive experiences and animations.
How Matter works

Connect your codebase
Link Matter to your existing repository and get a live preview running in minutes. Everything happens in an isolated environment, so there’s no risk to your production code.

Modify with Matter
Use simple prompts to modify your app instantly. Matter's AI agent handles the implementation, with no coding necessary.

Collaborate in real time
Say goodbye to localhost:3000 – Matter lets you share working prototypes instantly with teammates and stakeholders. Whether you're explaining ideas to decision-makers or validating with customers, you get feedback in minutes with functional demos instead of static mockups.

Hand off what you built
Matter integrates directly with GitHub and allows you to create a GitHub Pull Request from its interface. Used to a more traditional handoff? No problem – Matter creates an issue draft with generated code and documentation.
