Desktop app for repetitive file work
Process PDFs, audio, video, and media links with guided steps and clear summaries before anything runs.
Diametheus is free while we are in public beta. Optional licenses are a way to support the project early and keep your tier pricing before version 1.0 ships.
Use the same predictable flow across documents and media: choose files, choose result, choose output, review, and run.
Download media from links and keep the same guided workflow with a final review step before writing files.
Diametheus keeps every workflow simple and repeatable.
Diametheus is built as a local desktop app. Your files stay on your computer while trusted helper tools do the heavy work behind a clean UI.
Creators, consultants, office teams, and technical users who want reliable batch workflows without re-learning commands every month.
Choose your platform and start with one workflow you repeat often.
