Zendesk and Intercom both offer a shared inbox, live chat, a help centre and an AI agent that answers customers. The real differences are how they price seats and AI, and which channels each plan includes.
The short verdict
Pick Zendesk if you want one tool for email, chat and phone, or you only need email tickets and want the lowest entry price.
Pick Intercom if chat on your site or app is your main channel, and you want an AI agent that is part of every plan and priced per outcome.
Both have a 14-day trial. Use the same week of real questions in each.

What you get at the entry level
Zendesk Support Team is the cheapest plan here, but it covers email and ticketing only. Chat and phone start at Suite Team.
Intercom Essential includes live chat, email support and its AI agent from the start. Intercom says every plan includes unlimited live chat, support email and in-app chat. SMS, WhatsApp, phone and email campaigns are charged by use.
So for chat plus email, the fair comparison is Intercom Essential at $29 against Zendesk Suite Team at $55, both billed annually.
How each one charges for AI
Intercom charges $0.99 per Fin outcome. An outcome is counted when the customer says the answer helped, does not ask for more help, or Fin completes a workflow you set up. You pay once per conversation. Its Copilot assistant for your team is $29 per agent a month billed annually, or $35 monthly, and each agent gets 10 Copilot conversations a month free.
Zendesk counts automated resolutions, which are requests its AI agent solves without a person. Support Team and Suite Team include 5 per agent per month. Suite Professional includes 10. Extra resolutions cost $1.50 each with a commitment, or $2.00 pay-as-you-go. Copilot is $50 per agent a month, billed annually, on Suite Professional and above.
At list price, each extra AI answer costs less on Intercom. Zendesk includes a small number in the plan. For a small team, both bills depend mostly on how many questions the AI can really answer, which depends on how good your help articles are.
Trials
Zendesk offers a 14-day free trial with the features of a higher plan. Intercom offers a 14-day free trial with no credit card, including Fin and add-ons. Intercom also runs an Early Stage program for startups. At the time of writing, its page mentions up to 93% off for eligible startups.
Who each one suits
Zendesk suits businesses with several channels, especially phone, and teams that expect to grow into many agents with detailed routing.
Intercom suits online businesses and software products where customers ask questions in a chat window, and teams that want the AI agent to handle the first reply.
Neither may be needed if you are one person answering a handful of emails. A normal inbox with good saved replies can work for a long time. Customer service email templates is a good place to start those.
How to decide
- Look at where last month's questions came from: email, chat or phone.
- Count the people who answer. Both charge per seat.
- Estimate how many questions a help article could answer, then price the AI on both.
- Write your ten most common answers before the trial, so the AI has something true to use.
- Run both trials with the same questions and compare cost and quality.
