Cassidy AI - Pros & Cons
Pros

- ✗Real-time knowledge sync is locked behind the Enterprise plan — Starter users deal with 24-hour sync delays
- ✗No self-hosted or on-premises option for organizations requiring full data sovereignty
- ✗Limited to three user seats on Starter plan, making it impractical for team evaluation beyond a small pilot
- ✗Chrome extension dependency for some features limits accessibility for non-Chrome users
