One thread, all the context

Messages, announcements and files
in the same place.

The conversation stops being just another tab. The announcement, the date, the note and the file live next to the decision that made them possible.

The problem isn't the chat

The work doesn't fit in fourteen tabs.

The conversation lives on one side, the announcement on another, the date in the calendar and the decision gets lost in a thread. ONMI brings the context together so your team doesn't have to hunt for where everything went.

01

Conversations with memory

Channels, DMs and threads with search, reactions, files and notes. Context doesn't leave when the meeting ends.

02

Visible decisions

Announcements with comments and mentions. What matters doesn't compete with fifty messages nobody remembers.

03

Your team, not a tenant

It runs on your domain and stays with your brand. Your data isn't another company's product.

One product, all the context

This is what working in ONMI feels like.

Real screenshots, not a smoke mockup. Explore the parts your team will use every day.

Private access, no noise.

Your team enters its own space with 2FA, revocable sessions and a door that is never shared with third parties.

  • 2FA with an authenticator app
  • Revocable sessions and devices
  • No hidden access and no chat readers

This is how it moves

The conversation
already does the work.

Write, mention someone and turn an idea into a task. Without jumping to another tool, without losing the thread.

    Ask in the channel.Context is in the conversation, not in a separate document.

Everything you need, nothing you don't

A smaller tool.
A more focused team.

No endless menus or integrations nobody set up. Just the right pieces to talk, decide and move forward.

Announcements people actually read

Publish with images, video, reactions and comments. Mentions notify the people who matter, not everyone.

Threads with a destination

Replies don't vanish into the channel. Every thread keeps its context and its latest reply.

Calendar with categories

Internal meetings, clients, projects or personal. Every event has a color and filters in one tap.

Notes that work

Tasks, tags, pinning and autosave. A personal notebook you can also share when needed.

In your pocket and on your desktop

Install ONMI as a PWA on mobile or download the app for macOS, Windows and Android. Your workspace, wherever you are.

Everything included

A complete platform.
No fine print.

This isn't a wish list: it's what already works in your installation. No add-ons, no per-user fees and no half-finished features.

Privacy by design

Real privacy,
not a promise.

ONMI has no chat reader for administrators. Auditing is separate from content: it records actions, not conversations. Private files can only be opened by members of the channel.

  • 01
    Metadata-only auditWho did what and when. Never the text of a message.
  • 02
    Attachments with membershipAn admin can manage the file, not read it if they don't belong to the conversation.
  • 03
    Revocable sessionsActive devices, remote sign-out and 2FA when the team needs it.
