Three platforms
Personal. Community. Business.
Each platform is fully isolated from the others. Your data, your members, your brand.
Community platform
For an association, club, neighbourhood, choir, or family. Bulk-invite members, share files, organize together.
Organization platform
For a company or NGO. Verified identities, admin roles, audit trail, your own AI provider.

FAQ
Frequently asked questions
Is the demo real?
The demo shows the real system shell (desktop, windows, system bar, app launcher) and the real UI for each app. There is no real backend: nothing you type is sent to a server, nothing is encrypted. The demo resets every 24 hours.
Can I sign in from the demo?
No. The demo is read-only and isolated. To use a real workspace, request an invite via the contact form.
Does it work on mobile?
Yes. The workspace is fully responsive and runs on tablets and phones.
