Comparison
KnownBase vs Slack AI
Slack AI summarizes what happened today. KnownBase remembers what happened 6 months ago — and who decided it.
| Capability | Slack AI ($15/user) | KnownBase ($12/user) |
|---|---|---|
| Channel summaries | Best in class | Good |
| Persistent memory (months) | Session only | 6+ months |
| Knows who each person is | — | 6-dimension profiles |
| Decision tracking with "why" | — | Temporal versioning |
| Cross-platform (GitHub, Jira, email) | Slack only | 12+ integrations |
| Pricing model | All seats required | Per active user |
| Price | $15/user (all seats) | $12/user (active only) |
The bottom line
Slack AI is great at "What happened in #engineering today?" — but it forgets everything when you close the tab. It doesn't know that Sarah is your payments expert, that the team chose Kafka in Q3, or that only Alex understands the billing code.
KnownBase is permanent memory that grows over months, connects to all your tools, and understands your people — not just their messages.
Plus: Slack AI forces you to pay for all seats. KnownBase charges only for active users — 20% cheaper even before you count unused seats.
