Everything a team needs to communicate
These are the core features. We can extend them or add new functionality on request.
Every device
Apps for phones and computers, plus a web version.
The whole company in one list
You always see all of your colleagues — no need to search for or add contacts.
Chats and groups
Message colleagues one-to-one or in groups.
Audio and video calls
Call any colleague straight from the chat.
File sharing
Send documents, images and other files in any conversation.
Personal notes
Send messages to yourself — just tap your own name at the top of the app.
Sync across devices
All messages, including your notes, are available on your computer and your phone alike.
Voice messages
Record voice messages of up to 10 minutes. With transcription enabled, the text appears right under each message.
Call transcripts
With call recording enabled, the sound of calls is transcribed in the background. The transcript appears in the chat with speaker names and times.
Secure by design. Users cannot register themselves, delete messages or change their display name or avatar — only the administrator can. This prevents impersonation and scams, and keeps a complete record of work communication.
Full control over your workspace
Users
Create accounts with a login, display name and avatar. Each login is unique across the whole server.
Disabling users
Temporarily block sign-in without deleting anything.
Removing users
Delete a user together with all their messages — or remove the user and keep the messages.
Companies
Create independent communication spaces whose users do not see each other.
Appearance
Choose a chat background for each company.
Limits
Set messages per hour and the number and size of files per day for each user.
Voice transcription
Turn automatic transcription of voice messages on or off.
Call recording
Turn call recording with transcription on or off.
Groups
Overview of all group chats in each company.
Statistics
Usage reports: messages, files, storage and calls.
Diagnostics
Connection history and app logs for each user to investigate connection problems.
App versions
See which app version each user has and make an Android update mandatory.
Using the app
Chats
A familiar chat window: pick a contact, then send messages, files and voice notes, or start an audio or video call.
Personal notes
Tap your own name at the top, above the contact list, to open your private notebook.
Creating a group
Open the menu (⋮) on the main screen, choose New group, enter a name and select members.
Group rights
Only the group creator can change its name and picture and add or remove members. Any member can leave; if the creator leaves, their rights pass to the longest-standing member.
Group details
Tap the group header to see its members and management options.
Read receipts
One check mark — delivered to the server. Two check marks — read by your colleague, or by every member in a group.
