Order without bureaucracy
Your community. Your access rules.
Invite members, appoint administrators and revoke access in seconds. No vendor ticket and no waiting for someone else’s support team.
- Shared roles and channel owners
- Instant account blocking
- Password or Face ID, Touch ID and security keys
Private where it matters
Sensitive talks, encrypted end to end.
Create a secret web chat when even the server should not be able to read the conversation. Regular work chats remain searchable and easy to administer.
- Encryption keys stay on participant devices
- Secret chats are hidden from mobile clients for now
- Clear distinction between managed and confidential work

Suggested version
Could you please send the final estimate before lunch?
Only the current draftNo chat history · no participants · no files
External provider chosen by the administrator
Optional writing assistant
Turn a rough draft into a clear message.
Only when a user asks, Fiducio sends the current unsent draft to the external provider configured by the administrator. Chat history, participants, files and sent messages stay out of the request.
- Disabled by default; the administrator decides whether to enable it
- Works with GigaChat or an OpenAI-compatible service
- The assistant only suggests — the user reviews and confirms the replacement
- No local model or GPU is required on the Fiducio server
One conversation, every format
Meet face to face. Show the work live.
Start a private call or open one that everyone in a group or channel can join. Camera, sound and screen sharing work together in the same call.
- Audio and video with active-speaker indication
- Camera and screen sharing at the same time
- Full screen, picture in picture and local recording
