Real-Time Collaborative Editing
Documents supported real-time co-editing with cursor positions and selections visible for all collaborators. Yjs CRDT ensured conflict-free merges even with offline edits. Rich formatting, embeds, slash commands, and @mentions created a Notion-like experience. Version history tracked every change with rollback capability. Templates accelerated common workflows (meeting notes, RFCs, sprint planning). Export to PDF/Markdown maintained formatting. Documents lived alongside relevant messages, eliminating the 'where did we save that?' problem.
Integrated Video Conferencing
One-click video calls from any message thread—no separate links or scheduling. P2P WebRTC for 2-5 participants provided crystal-clear quality with <200ms latency. Larger calls used SFU (Selective Forwarding Unit) architecture supporting up to 50 participants. Screen sharing included annotation tools for collaborative design reviews. Background blur and virtual backgrounds maintained professionalism from anywhere. Post-call transcripts with speaker identification and searchable content turned meetings into searchable knowledge.
AI-Powered Productivity
The AI assistant automatically summarized long threads when users caught up after being away, extracting key decisions and action items. Meeting transcripts were processed to generate action items assigned to specific team members. Intelligent search understood natural language ('pricing discussion with Sarah in March') and ranked by relevance considering recency, participant involvement, and user behavior. Weekly team digests highlighted accomplishments, bottlenecks, and suggested process improvements. Privacy controls let users opt-out of AI features if desired.
Enterprise Features & Security
SSO integration with Okta, Azure AD, and Google Workspace streamlined onboarding. SCIM provisioning automated user lifecycle management. SOC 2 Type II certification, GDPR compliance, and data residency options (US, EU, APAC) satisfied enterprise requirements. Granular permissions controlled access at team, channel, and document levels. Audit logs tracked all security-relevant actions. DLP (Data Loss Prevention) policies prevented sharing of sensitive patterns. Despite enterprise features, the core product remained beautifully simple for small teams.
