What is Refract?

Refract is a LaTeX workspace with an editor, compilation, PDF preview, and an AI assistant. It helps you write and review articles, theses, and other documents without leaving your project.

Can AI change my work without permission?

Assistant suggestions appear as changes you can compare, accept, or reject. You decide what becomes part of your document.

Can I bring my existing LaTeX projects?

Yes. You can import a folder or a ZIP file, including exports from Prism. Your files stay LaTeX files, and you can export your project whenever you need.

Where are my documents stored?

In the self-hosted version, projects are stored in your own Refract instance. If you connect an external AI provider, requests and the necessary context are sent to that provider. Terms for the future subscription service will be shared before launch.

What will the subscriptions include?

Free includes up to 3 projects, 200 MB of storage, and 1 compilation at a time, without priority. Plus costs €6 + VAT and includes up to 100 projects, 2 GB, and 2 parallel compilations. Pro costs €15 + VAT and includes everything in Plus, plus AI through tokens. Every plan lets you connect your own AI with an API key. The Pro token allowance is yet to be confirmed.
