Zendesk AI

Zendesk AI is an AI-powered customer service platform that automates ticket resolution and assists support agents across multiple channels

Bakes AI agents and an agent copilot directly into the Zendesk suite, resolving routine tickets and drafting replies where support teams already work. The value is tied to living on Zendesk and it lands as a premium add-on, so it pays off mainly for existing customers.

Ada

Ada is an AI-powered customer service automation platform that handles support conversations across voice, messaging, and email channels

The strongest pick for scaling tier-one support without adding headcount, resolving routine inquiries across channels and languages. But outcomes hinge on the quality of your knowledge base, so it fits high-volume support orgs more than thin ones.

Forethought

Forethought is a generative AI platform designed for customer support and CX teams, offering AI agents that handle customer inquiries across multiple channels

Forethought automates tier-one support by resolving and triaging tickets inside existing helpdesks like Zendesk, with intent detection that routes the rest. Best for high-volume support teams, but it needs solid historical ticket data and tuning to perform well.

Tidio AI

Tidio AI is a customer support platform featuring Lyro, an AI chatbot that automates up to 90% of customer queries and resolves 64-67% of conversations automatically in under 6 seconds

Its Lyro bot is a practical fit for small e-commerce and service businesses wanting a chatbot that answers common questions from your own content. But it can stumble on nuanced queries and still hands off to humans fairly often.

Sierra

Enterprise conversational AI agents for customer experience, billed on the outcomes they resolve.

Sierra is the blue-chip pick for Fortune 500 CX teams that want a highly capable, outcome-priced AI agent and can absorb a six-figure, sales-led commitment. Overkill and over budget for small teams.

Decagon

Enterprise AI concierge agents that autonomously resolve customer support across chat, email, and voice.

Decagon is one of the most credible enterprise players in autonomous support, but its custom six-figure contracts and white-glove onboarding put it firmly out of reach for small teams. It shines for large brands with high ticket volume and the resources to invest in a serious deployment.

Voiceflow

A collaborative platform to design, build and ship AI agents.

Voiceflow stands out for collaboration and design: teams can map, prototype and ship chat and voice agents on a shared visual canvas with support for multiple LLMs. That polish comes at a price, since cost is driven by both editor seats and a usage-based credit layer, so seats and interaction volume both matter. Voiceflow does not publish fixed prices, so model your expected usage and confirm current rates with their team. It is a strong choice for teams that value cross-functional collaboration, less so for a single builder on a tight budget.

Gorgias

The Shopify-native helpdesk with AI agents built for ecommerce support.

Gorgias is one of the strongest helpdesks for Shopify and ecommerce brands, and its ticket-based (not seat-based) pricing is genuinely appealing when you want to add agents freely. The honest caveat is cost predictability: on top of ticket tiers, the AI Agent is billed per resolved conversation, and Gorgias's own billing rules mean a cleanly automated case can be counted both as a ticket and as a resolution. High-volume stores should model expected ticket and resolution counts before committing, because the effective price can be well above the sticker plan price.

Maven AGI

Enterprise AI agents that autonomously resolve customer support at scale.

Maven AGI is a credible, well-funded entrant in enterprise AI customer support, and its focus on measurable autonomous resolution across chat, email, and voice is aligned with what large CX teams actually want. The honest caveats are that pricing is fully custom with nothing published, so you cannot evaluate cost without a sales process, and that the vendor's headline resolution figures come from its own field research on top deployments, meaning your results depend heavily on knowledge quality and integration effort. This is an enterprise procurement, not a self-serve tool.

Lorikeet

Outcome-priced AI customer support that follows complex workflows.

Lorikeet's pitch, an AI agent that executes complex workflows and runbooks rather than just answering FAQs, is genuinely differentiated and well-suited to fintech, healthcare, and other high-stakes support. Outcome-based pricing (pay per resolved ticket) is buyer-friendly in principle because it ties cost to value. The honest caveats are that it is a younger company, the entry price starts around $1,500/month so it is not aimed at small teams, and the quality-versus-simplicity trade-off means you get the most out of it only if you invest in defining the workflows the agent follows.

Kustomer AI

Kustomer AI is a CRM-native customer service platform that combines AI agents with human support workflows

Kustomer ties customer service into a CRM-style conversation timeline, with AI agents and deflection aimed at high-volume support. Best for retail and ecommerce teams handling chat and email at scale; smaller operations may find the setup and cost hard to justify.

Freshdesk Freddy AI

Freshdesk Freddy AI is an AI assistant integrated into Freshworks' customer support platform that automates ticket resolution, suggests responses to agents, and provides workflow automation

A reasonable add-on for teams already on Freshdesk, drafting replies, summarizing tickets, and powering self-service bots from your knowledge base. The caveat is its quality depends heavily on well-maintained help content, and it is tied to the Freshworks ecosystem.

Crisp AI

Crisp AI is a customer messaging platform with AI-powered support features, including Hugo AI for automated responses and a shared inbox for team collaboration

Good value for small teams wanting a shared inbox, chatbot, and AI reply drafting bundled into one affordable messaging platform. It is less enterprise-grade than Intercom or Zendesk, so complex routing and large-scale support needs may outgrow it.
