Which One to Pick
Pick Gladly Sidekick if
- Consumer brands with loyal customers. Retail, travel, hospitality. High repeat contact is what makes the person-centred model pay for itself.
- Teams with significant phone volume. Voice as a first-class channel in the same thread is rare and genuinely useful here.
- Organisations that dislike ticketing. If your agents complain that ticket numbers obscure the customer, Gladly is the structural answer rather than a workaround.
Look elsewhere if: B2B support, low-repeat businesses and anyone needing published pricing. The person-centred model earns nothing when customers contact you once, and at that point cheaper ticketing platforms are simply better value.
Pick Zendesk AI Agents if
- Enterprises with accumulated tooling. If your support stack has a decade of integrations behind it, Zendesk's ecosystem advantage is decisive and no comparison of agent quality will change that.
- Teams that want one vendor. Zendesk now supplies the agent, the QA layer and the agent assist from one contract. In a fragmenting category that has genuine operational value.
- Buyers worried about vendor stability. Zendesk is the acquirer in this market, not the acquisition target. For a three-year commitment that matters more than most feature comparisons.
Look elsewhere if: Zendesk is the wrong choice for small teams and for anyone who needs cost certainty up front. At $69 per agent for Suite Team before AI add-ons, a five-person team is paying meaningfully more than Zoho Desk or Freshdesk would charge for a similar outcome. It is also the wrong choice if you want the best available agent rather than the best available platform — Fin is the stronger agent, and teams whose only problem is ticket volume should compare the two directly rather than assume the incumbent wins.

Gladly Sidekick pricing
Custom and private pricing. Gladly Sidekick does not publish a rate, so you have to ask. Request a demo ↗
Gladly does not publish pricing. Expect a sales cycle and enterprise-level quotes, with Sidekick likely priced separately.
The comparison set is Kustomer, Zendesk Suite at the upper tiers, and Salesforce Service Cloud — not Freshdesk or Zoho. If you are weighing it against a $18-per-agent platform, you are in the wrong bracket.
Ask how Sidekick is billed. If it is per resolution, the same dynamic that generates complaints elsewhere in this category applies here too.
Zendesk AI Agents pricing
- Support Team — $19 /agent/mo billed annually. Email and ticketing, automations and triggers
- Suite Team — $55 /agent/mo billed annually. Adds AI agents and AI knowledge base across unified channels
- Suite Professional — $115 /agent/mo billed annually. Adds admin copilot and app builder
- Suite Enterprise — Custom. Quoted
- Copilot add-on — $50 /agent/mo billed annually. On top of the seat
- Workforce Engagement add-on — $50 /agent/mo billed annually. On top of the seat
- Contact Center add-on — $83 /agent/mo billed annually. On top of the seat
Zendesk publishes per-seat pricing across three tiers. Support Team runs $25 per agent per month for ticketing and basic reporting. Suite Team at $69 adds multi-channel support, help centre and AI tools. Suite Professional at $149 brings advanced workflows, custom dashboards and SLAs. Suite Enterprise is quoted rather than published.
The published figures are the beginning rather than the end of the calculation. The AI capability most buyers are actually shopping for — autonomous agents, Copilot, QA — arrives through add-ons on top of the seat price. G2 reviewers repeatedly raise total cost of ownership as the principal complaint, noting specifically that the Copilot add-on typically has to be licensed across the whole team.
Compared against the alternatives, Zendesk sits at the premium end of per-seat pricing. Freshdesk runs $18 to $95 per agent for a broadly comparable feature set, and Zoho Desk starts at $7. Against per-resolution competitors the comparison is harder: Zendesk charges whether or not the AI resolves anything, which is worse at low volume and considerably better at high volume than Intercom's $0.99 per resolution.
The honest summary on price is that Zendesk is not expensive per seat so much as expensive in aggregate, and that the aggregate is difficult to establish without a sales conversation. Model the seats, the AI add-ons and the QA licences together before comparing against anything else.
Both Tools in Depth
Gladly Sidekick
Gladly goes further than Kustomer on the same idea: it removes tickets entirely. Each customer has one continuous conversation that spans years and every channel, and agents work in that thread rather than in a queue of cases.
For consumer brands with loyal repeat customers — retail, travel, hospitality — this maps onto reality better than ticketing does. A customer who phoned in March and emails in July is one relationship, not two cases.
Sidekick is its AI layer, handling resolution autonomously within that model. Gladly is an enterprise-leaning product sold through a sales process, with pricing that reflects it.
No tickets
Not a UI preference — the data model has no case object. Agents see one thread per person across voice, chat, email and SMS. Genuinely different, and either clarifying or disorienting depending on how your team already thinks.
Sidekick
Autonomous resolution inside the person-centred model, so the AI has the customer's full history rather than a single ticket. Better context than most agents get. Not as widely deployed as Fin, so there is less independent evidence about it.
Zendesk AI Agents
Zendesk is the default against which every other product in this directory positions itself, and has been for well over a decade. It is the platform most support teams have either used or evaluated, with G2 listing more than 6,200 reviews at an average of 4.3 stars — by far the largest review base in the category. That scale is the product's central characteristic. Whatever Zendesk lacks in elegance it makes up in the fact that almost every tool, CRM and telephony provider your company already runs has a Zendesk integration.
What has changed recently is how Zendesk is acquiring its AI capability. Rather than building an agent from scratch, the company has bought three: Klaus, the QA platform now rebranded Zendesk QA; Ultimate, a service automation provider; and Forethought, acquired in March 2026 in a deal reported at over $200 million and completed within a fortnight of announcement. One analysis characterised this as a $500 million acquisition sprint across seven AI deals in three years. For buyers, that consolidation cuts both ways — fewer vendors to manage, but a stack whose components were designed by different teams and are still being knitted together.
The practical consequence is that Zendesk is now the low-risk choice in a category where four platforms have already been absorbed. If your primary concern is that your vendor will be bought and its roadmap redirected, Zendesk is the acquirer rather than the target. If your primary concern is cost predictability, it is one of the harder products in this directory to model, because the AI capability that matters is priced separately from the seats that carry it.
AI agents and the resolution platform
Zendesk's autonomous agents handle conversations end to end using natural language understanding, deflecting tickets and routing what they cannot resolve. Forethought's self-learning agents are being folded into what Zendesk calls its Resolution Platform, which is the company's explicit answer to Intercom's Fin. The capability is credible but newer than the platform around it, and buyers evaluating Zendesk in 2026 are evaluating an agent that is still being integrated rather than one that grew up inside the product.
Agent Copilot
Copilot sits beside human agents suggesting replies, surfacing context and recommending next steps. G2 reviewers consistently describe it as useful, and equally consistently object to the licensing: the add-on generally has to be purchased across all agents rather than only for the people who will use it. On a fifty-agent team where fifteen would benefit, that pricing structure materially changes the calculation.
Where Each One Breaks
Strengths and weaknesses on both sides, stated plainly.
Gladly Sidekick
What works
- The most committed implementation of customer-centred support available
- Voice handled properly rather than bolted on
- Sidekick sees the whole relationship, so its context beats most AI agents
The most committed implementation of customer-centred support available. Voice handled properly. Sidekick has better context than most AI agents because it can see the whole relationship.
What does not
- No published pricing, and an enterprise sales cycle
- Wasted on low-repeat businesses
- Smaller ecosystem than Zendesk or Salesforce
- Less independent evidence on Sidekick than on the market-leading agents
No published pricing and an enterprise sales cycle. Wasted on low-repeat businesses. Smaller ecosystem than Zendesk or Salesforce. Less independent evidence about Sidekick than about the market-leading agents.
Zendesk AI Agents
What works
- Largest integration ecosystem in customer support software
- Has absorbed Klaus, Ultimate and Forethought, reducing vendor sprawl
- Published per-seat pricing across three of four tiers
- Genuinely scales from small teams to very large contact centres
- Strong reporting through Explore
- AI agents, QA and agent assist now available from one contract
Zendesk's ecosystem is its genuine and durable advantage. With more than 6,200 G2 reviews at 4.3 stars it also has the largest body of independent evidence in the category, which is worth something when newer competitors have a few hundred reviews or none. Reviewers consistently praise Explore reporting for the quality of business decisions it supports, and describe ticket handling and teammate collaboration as straightforward. The recent acquisition strategy has real buyer benefit too: Klaus, Ultimate and Forethought bring capabilities that would otherwise require three additional vendors, three contracts and three integrations. And in a market where four platforms in this directory have been absorbed since 2024, buying from the acquirer removes a category of risk entirely.
What does not
- AI capability sits behind add-ons layered on seat cost
- Total cost of ownership is difficult to establish before a quote
- Interface is widely described as fragmented
- Copilot add-on must typically be bought for all agents, not just those who need it
- Suite Professional at $149/agent/month is expensive at scale
- Newly acquired products are still being integrated
The pricing model is the recurring complaint and it is structural rather than a matter of tiers. G2 reviewers repeatedly note that total cost of ownership climbs sharply once the AI Copilot add-on is included, and that the add-on generally has to be purchased for every agent regardless of how many will use it. The interface attracts consistent criticism as fragmented and difficult to navigate, which is the usual cost of a platform that has accumulated a decade of features. The AI capability, while credible, is newer than the platform and assembled from acquisitions rather than grown in place — Forethought closed in March 2026, so anyone evaluating it now is evaluating an integration in progress. Finally, at $149 per agent for Suite Professional, Zendesk is simply expensive relative to Freshdesk and Zoho Desk for teams that will not use its depth.
Where Each One Lands
Our reading of each, unchanged from its own review page.
Gladly Sidekick
Gladly is a strong fit for consumer brands with real customer loyalty, meaningful phone volume, and frustration with ticketing as a model. Removing cases entirely is a genuine architectural position and it pays off where repeat contact is high. It is also an enterprise purchase with no published pricing, which means a sales cycle before you can compare it to anything. For B2B or low-repeat support the premium buys you nothing, and Zendesk or Freshdesk are the better-value answers.
Zendesk AI Agents
Zendesk is the safe answer rather than the best answer, and for a great many teams safe is correct. Its ecosystem is unmatched, its review base is the largest in the category, and it is now the consolidator rather than a consolidation target, which removes a real risk from any multi-year commitment. The costs are a fragmented interface, AI capability that is still being integrated from three acquisitions, and a total price that is genuinely hard to establish before a quote. Model the seats, the AI add-ons and the QA licences together, then compare that number against Freshdesk. If Zendesk still wins, buy it with confidence.
Frequently Asked
Questions people search about Gladly Sidekick and Zendesk AI Agents.
What is Gladly?
A customer service platform with no tickets. Each customer has one continuous conversation across voice, chat, email and SMS that spans years.
Does Zendesk have AI agents?
Yes, across several products: AI agents for autonomous resolution, Copilot for agent assistance, and intelligent triage for routing. They sit at different tiers, which is the part buyers misjudge.
How much does Gladly cost?
Not published. Enterprise pricing quoted through a sales process, with Sidekick likely a separate line item.
How do I use Zendesk AI agents?
Enable them in the admin centre, point them at your help centre, then build answer flows. Actions against your own systems need marketplace connectors or custom development.
What is Gladly Sidekick?
Its AI agent, resolving autonomously inside the person-centred model — so it sees the customer's full history rather than one ticket.
Is Zendesk AI included in my plan?
Partly. Some capability is in Suite tiers, more sits behind the Advanced AI add-on, and the acquired Klaus and Ultimate features are priced separately again. Get the specific list in writing before signing.
Is Gladly better than Zendesk?
For consumer brands with high repeat contact and heavy phone volume, the model is genuinely better. Zendesk is cheaper, broader and has a much larger ecosystem.
How much does Zendesk cost?
Published per-seat pricing runs $25 for Support Team, $69 for Suite Team and $149 for Suite Professional, with Suite Enterprise quoted. AI agents, Copilot and QA are add-ons on top of those figures.
Is Gladly good for B2B support?
Not really. It targets consumer brands with loyal repeat customers. For B2B, Pylon or Plain fit better.
Is Zendesk AI included in the seat price?
Partly. Suite Team includes some AI tooling, but the capabilities most buyers shop for arrive as add-ons. Reviewers specifically note that Copilot generally has to be licensed across all agents.
