For studios, agencies and prepress.
You set up catalogues, brochures and books with your team. Clients proof through a link, the printer gets a checked PDF/X-4.
I approve new profiles by hand.

Collaboration
Your team works in the same document. At the same time.

Proofing
Clients edit the text themselves. No account, no PDF.

Typography
Its own composition engine. Screen, PNG and PDF are set identically.

Data
Medusa fills the pages from your list and updates new prices.

Colour and print
Medusa checks while you work and writes PDF/X-4 only if the file passes.
Exchange
IDML both ways. You place Word, PDF, images and fonts directly.
Workflows
Examples
They are on the program's start page, in German and English. Rebuild them and output them.
Questions
For multi-page print work, catalogues and ads, yes: Medusa works with paragraph and character styles, master pages, spot colours and prepress checks, opens and writes IDML and runs in the browser. Medusa is in beta.
Yes, through IDML (in and out), with styles, tables and footnotes.
Yes. The print PDF is built to PDF/X-4, with output intent and XMP identification. Medusa reads the finished file back in and checks it; «PDF/X-4» is only written when the file passes. This is not an independent certification.
No. Medusa runs in current versions of Chrome, Edge, Firefox and Safari.
Create a profile with your name and email address. New profiles are approved by hand; after that you open a document and send the link.
Documents, images and accounts are currently stored with Hostinger, the provider of the medusa.id42.xyz server. The site has no trackers and loads nothing from third parties, not even fonts. Background removal runs in the browser; the image never leaves your computer. AI features only run when you switch them on.
No. A link is enough to correct and approve; the layout stays locked.
Reading, commenting, changing text, approving: yes. Designing on a bigger screen.
I am a designer and prepress professional, and I examine candidates in the Swiss professional exams for polygraphs (print media technologists). I have been to many Adobe MAX events and I write in prerelease forums.
There I read every week what annoys people about their tools. Medusa solves what annoys me in my own daily work.
