WHAT MAKES CollabNowPro

Everything for the workday.

None of it with an outside platform operator.

One app instead of many

Mail, appointments, tasks, contacts, notes and files share one search and one Today view.

Your own servers

The app works with your organization's mail server and Nextcloud. No account with a cloud provider is needed.

Private mesh

The servers do not have to be publicly reachable on the internet. Each device is admitted individually; in mesh mode there is no direct fallback route.

Assistant under control

The app executes, not the model. Every change appears as a card that you confirm.

Reliable offline too

Recently loaded data remains readable in an encrypted cache. Changes count as done only after the server confirms them.

Open protocols

IMAP, SMTP, CalDAV, CardDAV and WebDAV. Your data stays in formats and on servers you can change at any time.
