Channels, threads & search
How this is scored
The daily surface: channel model, threading, mentions, files, and whether search can find a decision made eighteen months ago.
0 — Flat group chats with no threads; search covers recent messages only, and history is capped.
3 — Channels and direct messages with basic search, but threading is awkward or absent and file handling is a plain attachment list.
5 — Public and private channels, real threads, mentions and reactions, file sharing with previews, and full-text search across the whole history.
8 — Cross-organisation or guest channels with clear boundaries, message editing history, pinned and saved items, search with filters by channel, person and date, and a documented history limit or none at all.
10 — The archive is a working knowledge base: search that ranks well across years, threads that stay readable, channel lifecycle management (archive, rename, merge) without losing history, and export of a conversation in a form a human can read.
The Works Council Advocate
The captured page sells a mobile-first communication home for frontline teams, with targeted updates by role, shift or location and no corporate email required. We found no public information on channels, threads, mentions, search over history, or any history limit; an archive whose searchability is undocumented cannot be treated as a record of who spoke to whom. 1
