Just wrapped up my 14-day trial of both Zendesk’s Advanced AI and Intercom’s Fin. I was specifically testing the AI deflection features and, more importantly, how easy it is for a human agent to jump in and take over.
Here’s what I found on agent override:
**Zendesk:**
* The "take over" button is right in the ticket interface. One click and the AI stops, you’re in.
* **Big pro:** The agent gets a clear summary of what the AI already discussed. Saves so much time.
* **Con:** The override feels a bit "final." Hard to put the AI back on the thread smoothly if you want it to handle follow-ups.
**Intercom:**
* Agents can seamlessly type into the same chat thread. The AI recognizes the agent’s input and steps back.
* **Pro:** The handoff feels more natural and collaborative. You can let the AI handle the routine bits and jump in only for complex parts.
* **Con:** Less obvious visual cue that an agent has taken over. Could lead to confusion if multiple agents are watching a conversation.
For pure agent control and clarity, Zendesk wins. For a fluid, blended human/AI conversation, Intercom’s approach is more flexible.
What’s everyone else seeing? Any teams have data on deflection rates holding up after enabling these overrides?
Trial number 47 this year.
I run support for a 60-person SaaS company, and we've been in production with Zendesk Advanced AI for about eight months. I tested Intercom Fin extensively during our selection process.
Here's my side-by-side on the points I think matter most:
**Agent Takeover UX:** Zendesk's one-click button is unambiguous and logs an internal note, which is great for compliance. Intercom's implicit handoff is fluid but caused occasional "who's talking?" moments in my trial. For a high-volume team, Zendesk's clarity reduces errors.
**Pricing & Setup:** Zendesk AI add-ons start around $50/agent/month on top of Suite licenses, which gets steep. Intercom's Fin is bundled into their Pro plan ($99/seat/month), making it simpler but tying you to their ecosystem. Both have annual commit requirements.
**Context Retention:** You noted Zendesk's summary for agents - it's solid. Intercom's context window felt longer in practice, keeping more of the conversation history useful for the AI when you step back in. For complex, multi-turn issues, Intercom's "memory" was better.
**Workflow Integration:** Zendesk's AI actions integrate natively with Sunshine objects and ticketing flows. If your workflows are deep in Zendesk, it's powerful. Intercom shines in pure chat scenarios; for tying AI actions to backend systems, we found it required more custom code.
My pick is Zendesk for traditional support teams where agent accountability and ticket hygiene are paramount. If you're a conversational, sales-heavy team that lives in chat and values fluidity, Intercom's model is the better fit. To make it clean, tell us your average conversation length and whether your agents handle one or multiple conversations simultaneously.
Yeah, I noticed the same thing with Zendesk's "final" override. It's almost too clean. I tried using it to let the AI handle a follow-up ticket update, and it just wouldn't re-engage without me manually re-triggering the bot.
Have you found any workaround for that? I'm thinking something like tagging the ticket so the AI picks it back up on next customer reply, but Intercom's implicit handoff just felt more natural for those back-and-forth bits. The lack of visual cue in Intercom spooked me though - almost had two agents talking at once once.
