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 Team Lead
The only chat evidence is one-to-one, group and managed user group conversations with attachments, push notifications, and the ability to mute and archive conversations; we found no public information on threading, message editing history, pinned items, or search across conversation history — the only search evidenced is live search of people profiles in the directory. That sits below the mark where basic channels and search are documented, so a decision made eighteen months ago is not something these pages promise to find. 8
