Software for study and research.

Powerful desktop apps for writing, presenting and research, and for keeping private things private. Everything runs on your own computer, even without an internet connection.

Made to respect your work.

On your own computer

Every app is installed on your computer and works offline. Your files stay with you, not on someone else’s server.

No accounts or tracking

Nothing to sign up for, no advertisements and no telemetry, in the apps or on this website.

Free for non-commercial use

Personal, educational and research use costs nothing, under the PolyForm Strict licence. No subscription, no trial and no paid edition.
