Independent tools. Shared philosophy.
One job each
Each app does one thing well: summarize, collect, or capture. Use the one you need.
Independent by design
Separate apps with separate accounts and data. Nothing is shared between them, and none needs the others.
Clear about your data
Each app says where your material is kept: in your browser, in your SourceClip library, or on your Mac.
Made for work with sources
For writers, journalists, producers and researchers who gather material online and come back to it later.
Made by Three Things Media
The Source Apps are built by Three Things Media, an independent software publisher in Ingolstadt, Germany. The apps share a look and a way of working, but each one stands on its own, with its own site, help and support.
