Feature tour

Everything your team needs

Six integrated workspaces that replace a stack of disconnected tools.

Channels
Nook ChannelsNook MeetingsNook FilesNook Voice RoomsNook ActivityNook Admin

Organized channels for every topic — threaded replies, emoji reactions, inline file previews, and pinned messages keep conversations clear and searchable.

Structured meeting workflows with agendas, live notes, decisions, and action items. Every meeting ends with clarity on what was decided and who owns what.

A shared workspace for all your team's documents and attachments. Browse by channel, search across content, and preview files without leaving Nook.

Drop into persistent voice rooms for quick syncs, or host stage events for larger audiences. Screen sharing, participant management, and recording built in.

A unified Activity Inbox surfaces mentions, reactions, and task updates. Focus mode and quiet hours keep notifications from breaking your flow.

Fine-grained roles and permissions let you control exactly who can see and do what. Manage members, channels, and workspace settings from one place.

Persistent audio rooms for quick syncs and stage events for larger audiences. Drop in and out without scheduling.

Shared document workspace with full-text search across all attachments. Find anything in seconds.

Global Search

Find messages, files, decisions, and people across your entire workspace. Instant results, powerful filters.

Admin & Roles

Self-hosted

Your data stays
on your server

Nook runs on infrastructure you control under a paid self-hosted license. Your Portal customer account manages licensing and downloads but never grants access to local content.
