Are Enclessa direct messages end-to-end encrypted?

Yes. Direct messages and group direct messages are always end-to-end encrypted using MLS as specified in RFC 9420. There is no administrator override and no server-side copy of the plaintext.

Can administrators read channel messages in Enclessa?

In managed channels the server can read messages, which is what makes full-text search, retention policies and compliance export possible. Whether an administrator may read them is a permission the organisation grants or withholds, and every access is written to the audit log. Direct messages are encrypted and cannot be read by anyone outside the conversation.

Does Enclessa support threads and Markdown?

Yes. Replies collapse into threads with a dedicated thread inbox, and messages support full Markdown including tables, syntax-highlighted code blocks and LaTeX.

Can I search messages in Enclessa?

Yes. Managed channels are indexed on the server with PostgreSQL full-text search, covering message text and text extracted from uploaded files, with modifiers such as in:, from:, before: and after:. Encrypted rooms are searched on your own device against a local encrypted index.

Messaging that keeps its shape as you grow

Create your workspace See pricing

Enclessa messaging organises work into teams, categories and channels, with threaded replies, reactions, full Markdown and message search. Direct messages and group direct messages are end-to-end encrypted with MLS, while channels are readable by the server so that search, retention and compliance export can work on them. Which mode a room uses is fixed when the room is created and shown in the room itself, so nobody has to guess.

At a glance

Structure: Teams → categories → channels → threads
Direct messages: End-to-end encrypted, no administrator override
Search: PostgreSQL full-text over channels and file contents
Formatting: Full Markdown, code blocks, tables, LaTeX
Permissions: Bitmask checked in the data layer, not the interface

How is a Enclessa workspace organised?

A team is the top-level unit and holds its own categories, channels and roles. Channels can be public to the team or private to the people invited into them, and one level of sub-channel keeps a busy category readable without turning the sidebar into a filing cabinet.

Public channels, private channels, direct messages and group direct messages
Categories with an emoji, ordering and permissions of their own
Read-only channels and admin-enforced categories fall out of the permission model
Favourites, mute, unread-only view and channel bookmarks in the sidebar

What can a message do?

Everything a working conversation needs and little that it does not. Threads collapse under the message that started them and have an inbox of their own, so a busy channel stays a channel rather than a list of tangents.

Threads, reactions, pins, saves, permalinks and mark-as-unread
Edit and delete inside windows the organisation configures
Mentions for a person, a role, a custom group, @here, @channel and @everyone
Scheduled messages, reminders and voice messages
Link previews generated behind SSRF protection, never by fetching from your browser

How does search work when some rooms are encrypted?

The capability moves rather than disappearing. In channels the server can read the message, so the server indexes it: PostgreSQL full-text search covers message bodies and text extracted from uploaded files. In end-to-end encrypted rooms the server holds ciphertext and cannot index anything, so the same search runs on your own device against a local encrypted index.

Server-side full-text search across channels and file contents
File search over names and extracted document text
Client-side search for encrypted rooms, against a local index

What about files and attachments?

Uploads are scanned for malware before anybody can open them, images get thumbnails, and video and document uploads have their metadata and text extracted for search. Every file carries the organisation it belongs to, which is what makes an export or a deletion complete rather than approximate.

Drag-and-drop upload with image thumbnails and document previews
ClamAV scanning and media extraction in a dedicated worker
Attachments in encrypted rooms are encrypted with the message

What this does not do

Group channels are server-readable by design — that is what makes search and compliance export possible. End-to-end encryption covers direct messages and group direct messages.
There is no document co-authoring, wiki or spreadsheet. Files are stored, versioned and displayed, not edited.
A room cannot be switched between encrypted and managed after it is created, because either the old history would be exposed or it would become permanently unreadable.
