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 Skeptic
Channels come in four categories with permission controls over who adds participants or sends, and search is described as unified across messages, users, channels and departments with tags to narrow results. The word "threads" appears only in the AI server's list of what an agent can access, and we found no public information on threading in the interface, mentions, reactions, file previews, message history limits, or how far back search reaches. Search is a step above basic; the rest of what makes an eighteen-month-old decision findable is untested on these pages. 2 3 8
