What Problem Does Each Tool Solve?
Slack AI
Makes Slack channels easier to search, summarize, and navigate.
Good for: quick channel catch-up, thread summarization, basic Q&A on channel context.
Limitation: Only works inside Slack. No proactive cross-meeting or cross-tool intelligence. No source links for critical decisions/commitments.
Marzo AI
Solves the “coordination tax” problem: engineers waste hours in meetings, searching Slack, and hunting for updates.
Delivers proactive, role-based insights across all your work apps—not just Slack.
Key use cases:
Start every morning with a Daily Brief of what matters (decisions, risks, blockers, deadlines, overdue tasks) with direct links to source.
Skip meetings, get Follow Updates (only what’s relevant to you—no FOMO).
Pre-Meeting Intel so you show up prepared with all the latest context.
Ask Marzo: Ask “Why did we move this launch?” and get answers with receipts—across Slack, meetings, GitHub, Jira, etc.
