Kaizo vs Zendesk QA (Klaus)
The Kaizo alternative to Zendesk QA
Kaizo is a Zendesk partner. It runs on the Zendesk you already have and scores every conversation, human or AI, including the ones Zendesk's AI agents handle.

The short version
Kaizo is a Zendesk partner, so this is not either/or. Zendesk QA (formerly Klaus) is now part of Zendesk Contact Center, a suite that also sells voice, workforce management and AI agents. Kaizo does one job: it scores 100% of your conversations, human or AI, on the Zendesk you already have. And because Kaizo does not sell the AI agents that answer your customers, it can grade Zendesk's AI with nothing to protect.
Kaizo and Zendesk QA, feature by feature
Every row states the reason, not just a verdict.
| Capability | Kaizo | Zendesk QA (Klaus) |
|---|---|---|
| Coverage and automation | ||
| Automatic scoring of every conversation | Yes AutoPilot scores 100% of conversations against your own scorecard, with no sampling and no reviewer queue. | Partial QA is one included feature of a wider contact centre suite, and reviewers report AI scoring still needs manual review. |
| Always-on, hands-off mode | Yes AutoPilot keeps scoring continuously in the background. Nobody has to start a review cycle. | No Coverage stays bounded by the review cycles your team schedules and staffs. |
| Coaching generated per agent | Yes AI coaching cards are written per agent from their own conversations. Prep drops from hours to minutes. | Partial Coaching exists, but the analysis and the write-up remain a manager's job. |
| Scoring and trust | ||
| Every score traces back to the conversation | Yes Each score links to the evidence in the transcript, so disputes are settled by reading, not arguing. | Yes Klaus's scorecards are well liked, and reviewers credit it with identifying exactly what needs to improve. |
| Can grade AI agents without a conflict of interest | Yes Kaizo does not sell the AI agents that answer your customers, so it has nothing to protect when it scores one. That is structural, not a policy. | No The suite markets its own AI agents, so grading them is marking its own homework. |
| Insight and reporting | ||
| Reporting depth without a BI project | Yes Coverage, quality trends and coaching impact report natively, out of the box. | No Their own reviewers call reporting basic and difficult to learn, and say detailed reporting needs extra configuration or third-party integrations. |
| Fit and cost | ||
| QA you can buy on its own | Yes You add the QA and coaching layer to the stack you already run. No suite migration. | Bundled G2 lists the suite from $83 per agent per month, and reviewers ask for unbundled options instead of taking the whole package. |
| Time to implement | Days Connect the helpdesk, define a scorecard, switch on Autopilot. | Setup-heavy Reviewers describe setup and optimisation becoming complex once reporting, automations and channels all have to work together. |

Where the two tools actually differ
Klaus earned its reputation, and Zendesk QA carries it on inside Zendesk Contact Center, next to voice, workforce management and AI agents. That suite suits teams that want everything from one vendor. Kaizo suits teams that want an independent quality layer on top of the helpdesk they already run.
Kaizo does one thing. It scores every conversation against your standards, explains what moved the score, and drafts the coaching that follows. It runs on the Zendesk you already have, as a Zendesk partner, so nothing about your helpdesk has to change.
The neutrality point
If a vendor sells the AI agents that answer your customers and also grades them, it is marking its own homework. Kaizo does not sell customer-facing AI agents: its QA grades every agent, human or AI, from any vendor, on your scorecard. Kaizo’s agentic platform (running as a pilot in Q4 2026) works on quality behind the scenes, not in your customer conversations. That is a structural reason to trust the score, not a promise.
The migration
Your existing scorecards map across, and your historical ratings become the test set for tuning the AI before it scores anything live. Most teams are running in days.

FAQ
Frequently asked questions
Can we migrate from Zendesk QA without losing our history?
Yes. Your scorecards map across, and your historical ratings are useful to us. We use them to verify the AI matches your standards before it scores anything live.
How long does switching take?
Days. Once the rubric is set and your helpdesk is connected, AutoPilot starts scoring immediately.
Is this comparison fair?
It is compiled from Zendesk QA's public documentation and pricing. Vendors change what they offer, so if something here is out of date, tell us and we will correct it.
