Letterbook vs. Zendesk
Our AI-native approach beats the traditional helpdesk every time.
| Letterbook | Zendesk | |
|---|---|---|
| How fast can I get started? | AI starts solving tickets in 15 minutes | 2 weeks to hire & train agents, write docs |
| Ticket resolution quality? | Improves significantly with every ticket | Highly depends on the quality of the hire |
| Management overhead? | None | Hours each week in meetings and hiring |
“The AI drafts save us so much time and it gets better over time. CMD+K to write is also a game changer. We have tried Zohodesk, Helpscout and Freshdesk, and Letterbook is by far the most intuitive. Our team loves it.”
