Voiceflow named a 2026 Best Software Award winner by G2
Read now

Kore.ai is in the middle of a pivot. The platform that built its name on enterprise conversational AI for customer service is rebranding around agentic AI, riding fresh capital from AllianceBernstein, and racing to catch the shift from chatbots to autonomous AI customer service agents.
The big buyer-decision question in 2026 isn't whether Kore.ai is a good conversational AI tool. It's whether you bet on the pivot, or pick a platform that's already agent-native. This review walks through Kore.ai's current state (what shipped, what changed, what costs what) and how it stacks up against alternatives like Voiceflow, Cognigy, Dialogflow, and Sierra.
A lot has changed since most reviews of this platform were written:
At platform scale, Kore.ai says it powers roughly 450 million interactions a day for 200 million consumers and 2 million enterprise users across a Fortune 2000 customer base that includes PNC Bank, AT&T, Cigna, Coca-Cola, Airbus, and Roche. That's the credibility floor any reasonable comparison has to start with. Kore.ai is not a small player. The question is whether it's the right player for you.
For broader context on where this whole category is moving, see our agentic AI in the contact center 2026 landscape piece.
Kore.ai is an enterprise AI platform for building, deploying, and orchestrating AI agents (chat and voice) across customer experience, employee experience, and contact-center use cases. The current flagship product is the Kore.ai AI Agent Platform, the platform formerly known as XO, for "Experience Optimization." It targets large enterprises that want a managed platform with strong analyst coverage rather than a developer framework.
The no-code visual builder lets non-engineers compose flows, while developers can extend with custom APIs and integrations. Kore.ai also ships Kore.ai Academy, a structured learning environment for business and technical users to ramp on the platform.
Three things, mainly:
This is the question most reviews get wrong, because Kore.ai changed its model after the early days. Here's the actual 2026 picture:
If you're a small or mid-market team, the Standard plan's 15-minute-session billing model can scale unpredictably. If you're an enterprise with a six-figure budget and a procurement process that expects custom contracts, the Enterprise plan is normal-looking. There's no $50/month or $500/month flat tier; anyone quoting one is reading a pre-2025 article. For a structured way to model the buy decision, see AI customer service ROI for enterprise.
Kore.ai sits in the enterprise conversational-AI-becoming-agentic-AI category. Honest peer set:
The pattern you're noticing isn't an accident. Three of Kore.ai's nearest peers (Cognigy, LivePerson, Dialogflow) have either been acquired, deprecated their main product, or rebranded inside a larger parent. The category is consolidating. Kore.ai's AllianceBernstein round is the bet that it can stay independent and ride the agentic-AI wave on its own.
Compact comparison for buyer-evaluation purposes:
| Voiceflow | Kore.ai | |
|---|---|---|
| Starting price | Always-on free tier; usage-based paid pricing | $100 minimum purchase, $500 free credits valid 90 days; Enterprise from ~$300K/yr |
| Pricing model | Per-message and per-token usage | 15-minute conversation sessions |
| Free option | Free tier, no card required, no time limit | 90-day free-credits window |
| Model support | Model-agnostic: OpenAI, Anthropic, Google, AWS Bedrock, bring-your-own | Multi-LLM via Model Hub: OpenAI, Azure, AWS Bedrock, plus XO GPT |
| Voice & phone | Native first-party channel with call_forward, dtmf, two-socket transport, multi-provider STT and TTS | Voice via partner integrations |
| Agent architecture | Workflows (deterministic) plus Playbooks (LLM reasoning) plus Tools (Function, API, MCP) | Visual builder, flow-centric architecture |
| Production tooling | Environments (dev, staging, prod), Evaluations, Observability | Forrester and Gartner Leader, mature enterprise tooling |
| Named customers | Turo, StubHub International, Sanlam Studios, Trilogy | PNC Bank, AT&T, Cigna, Coca-Cola, Airbus, Roche |
| Security & compliance | SOC 2 Type 2, PII masking | Enterprise security, on-prem options on Enterprise plan |
| Best fit | Builders and CX teams that want speed, voice, and model choice without a six-figure floor | Fortune 2000 teams that need procurement-grade contracts, MS Agent 365 and AWS partnerships, deep enterprise compliance |

Voiceflow takes a different shape than Kore.ai. It is built for builders (designers, conversation engineers, developers) to ship agents fast, without committing to a $300K floor or a 15-minute-session billing model. Five differences matter most.
Voiceflow's runtime supports models from Anthropic (the default is claude-4.6-sonnet), OpenAI, Google, AWS Bedrock, plus bring-your-own. You're not locked into one provider's roadmap. Kore.ai opened up Model Hub, which is a real change from the XO-GPT-only era. But Voiceflow has been model-agnostic from day one, with the prompting and tooling built around that assumption. See our agentic AI and Anthropic AI pieces for the broader model landscape.
Voiceflow gives you two primitives for two different jobs:
Kore.ai's architecture is flow-centric, which is fine for chatbot-class tasks. For genuine agentic work, where the agent needs to reason across multiple turns, the workflow-and-playbook split is more honest about which parts of your problem are deterministic and which aren't.
Voice is a first-party channel in Voiceflow. The call_forward tool transfers calls to a human or another number. The dtmf tool captures keypad input for IVR menus or PIN entry. Two-socket transport (separate inbound and outbound streams), multi-provider STT and TTS (Deepgram, ElevenLabs, Google, Amazon Polly), and voice-specific output rules are part of the core platform. If you're replacing a voice chatbot deployment or building one from scratch, voice doesn't sit on the side as a partner integration.
Production AI agents need more than a builder. Voiceflow ships:
Kore.ai has equivalents at the Enterprise tier. The difference is access: these are available on Voiceflow's standard plans, not gated behind a six-figure contract.
Voiceflow is SOC 2 Type 2 certified, supports PII masking, and meets the enterprise security standards that regulated teams need. You don't need to be on a $300K contract to get them. For a fuller breakdown of what to evaluate in any enterprise AI platform, see our AI agent builder security and compliance enterprise guide.
Voiceflow is in production at Turo, StubHub International, Sanlam Studios, and Trilogy, among others, across CX automation, voice, internal employee assistants, and lead capture. Different shape of customer from Kore.ai's Fortune-2000 list, similar scale of expectations.

Kore.ai's Standard plan offers $500 in free credits valid for 90 days when you sign up, plus a $100 minimum purchase to start using the plan. Development and testing are always free; billing kicks in only after a bot is published and handling real conversations. There is no time-boxed "30-day free trial" anymore. The model changed in 2025.
Standard: pay-as-you-go starting at a $100 minimum purchase, billed in 15-minute conversation sessions. Optional Standard Support is $1,000/month for weekday email support. Enterprise: custom pricing, with reported deal sizes starting around $300,000 per year, plus on-prem deployment options, premium features (Universal Bots, Topic Modeler), and 24/7 premium support.
Kore.ai is an independent company, founded by Raj Koneru (still CEO). In January 2026 it raised a strategic growth round led by AllianceBernstein Private Credit Investors, with continued participation from Vistara Growth, Beedie Capital, and Sweetwater Private Equity. It has not been acquired and has not made acquisitions of its own.
Honest shortlist of platforms that compete in the same enterprise CX and agentic AI category:
It's not really an apples-to-apples comparison. ChatGPT is a chat product wrapped around OpenAI's models. Kore.ai is an enterprise platform that uses models like OpenAI, Azure OpenAI, AWS Bedrock, and its own XO GPT to build and run agents inside your business systems. If you need a consumer chat product, use ChatGPT. If you need a platform to deploy AI agents into customer service or internal workflows with governance, integrations, and analytics, that's a platform-layer decision. Kore.ai is one option, Voiceflow is another.
