Kaizo, the #1 CallMiner alternative
Score 100% of your customer conversations automatically, with every score linked back to the words that produced it, and go live in days instead of months. No category syntax to hand-build, no analyst team to keep feeding the tool, and no AI agents of our own, so we can grade any conversation without marking our own homework.
Rated 5.0 on G2 · EU AI Act ready · SOC 2 and ISO 27001 certified







The short version
CallMiner earned its reputation on analytics depth, and it genuinely does deliver quality at scale. Its own reviewers describe moving from manual QA to automated QA and auditing volumes they could never reach before, so this page does not argue about coverage. It argues about what that coverage costs you. Their own buyers report roughly 5 months to implement and 19 months to payback, their reviewers hand-author the category syntax the platform runs on, one says the AI capability is currently a bit behind, and a coaching user says plainly that there is not enough AI in the coach platform. Kaizo scores every conversation from day one with no syntax to write, links every score to the evidence in the transcript, and turns each one into per-agent coaching.
How Kaizo compares to CallMiner
Every row states the reason, not just a checkmark. Competitor detail is drawn from public reviews and verified buyer data, current as of July 2026.
| Capability | Kaizo | CallMiner (Eureka) |
|---|---|---|
| Coverage and automation | ||
| Automatic scoring of every conversation | YesAutoQA scores 100% of conversations against your own scorecard, with no sampling and no reviewer queue. | YesCredit where it is due. Their reviewers describe the move from manual QA to automated QA, and assessing quality at a scale they could not audit before. |
| Scoring that needs no hand-built query syntax | YesAutoQA reads the conversation against your scorecard. There is no category or query language to author, debug or maintain. | NoTheir reviewers build categories and syntax by hand, ask for duplicate-syntax detection as a feature, and call category management tedious. |
| Coaching generated per agent | YesAI coaching cards are written per agent from their own conversations. Prep drops from hours to minutes. | PartialCoach is real and reviewers value it, but one of their own coaching users says outright there is not enough AI in the coach platform. |
| Trust and neutrality | ||
| AI you do not have to re-check | YesEvery score links to the evidence in the transcript, so you check by reading. Teams raise the automation rate as trust builds. | PartialIn their own reviewer’s words, parts of the AI capability are currently a bit behind. Accuracy is also among their top complaint tags. |
| Scores that survive an agent’s challenge | YesEach score links to the evidence in the transcript, so disputes are settled by reading, not arguing. | PartialReviewers concede transcription errors on complex accents that affect sentiment accuracy. When sentiment feeds a scorecard, that is a fairness problem. |
| Can grade AI agents without a conflict of interest | YesKaizo does not sell AI agents, so it has nothing to protect when it scores one. This is structural, not a policy. | NoTheir own profile markets voice-first virtual agents and the monitoring of AI automation together, so the QA layer grades its vendor’s own output. |
| Time, effort and cost | ||
| Time to implement | DaysConnect the helpdesk, define a scorecard, switch on Autopilot. | About 5 monthsTheir own buyers’ verified figure on G2. |
| Time to ROI | FastUiPath measured 200% ROI with 100% of QA automated. | About 19 monthsTheir own buyers’ verified figure. |
| Runs without a dedicated analyst team | YesAutopilot keeps scoring continuously in the background. Nobody has to operate it or start a review cycle. | Operator-ledAdministrators outnumber everyday users in their reviewer base, and reviewers describe building syntax and reorganising categories as part of the job. |
| Fit and focus | ||
| Native CRM integration | YesNative, out-of-the-box integrations with Zendesk and Salesforce. Kaizo reads every conversation straight from the CRM you already run, which is what lets teams go live in days. | PartialReviewers report technical issues with integrations, and difficulty connecting certain telephony or CRM providers. |
| G2 rating | 5.0Highest rating in the QA category. | 4.5Strong, with learning curve and accuracy tags as the top complaints. |
Why CX teams are moving off CallMiner
In their customers’ own words. Every quote below is a verified public G2 review of CallMiner Eureka.
One area where CallMiner is currently a bit behind is in parts of its AI capabilities, although it’s clear this is being addressed in upcoming platform updates.
Speech Analytics Platform Analyst, Enterprise, April 2026With Kaizo: AI scoring is the whole product, not one capability inside a speech analytics suite waiting on a roadmap. Every score links to the evidence in the transcript, so you judge the AI by reading it rather than by taking the release notes on faith.
not enough AI in the coach platform
Verified User, Mid-Market, April 2026With Kaizo: the coaching card is the output, not a blank form. Kaizo writes it per agent from that agent’s own conversations, which is why EverHelp cut coaching prep by 75% across 16 domains.
There are also occasional transcription errors with complex accents, which can have a minor impact on sentiment accuracy
Verified User in Insurance, Mid-Market, October 2025With Kaizo: every score links back to the evidence in the transcript, so an agent can see exactly which words drove it. A score nobody can trace is a score nobody can defend, and your agents know it.
I think it would be a neat feature if the system could highlight any duplicate syntax as I’m building it.
Verified User in Hospital and Health Care, Mid-Market, June 2026With Kaizo: there is no syntax to build, so there is none to de-duplicate. AutoQA reads the conversation against your own scorecard, and your analysts spend the week acting on findings instead of feeding the tool.

Frequently asked questions
Is CallMiner a bad product?
No, and anyone telling you otherwise is selling. CallMiner is deep, its analytics are genuinely strong, and its reviewers describe assessing quality at a scale they could never have reached manually. That is the same coverage story we tell, and we are not going to pretend they cannot deliver it. The question is what it takes to get there and what you can do with it once you have it: roughly 5 months to implement by their own buyers’ account, hand-built category syntax underneath, and 19 months to payback. Kaizo starts scoring the week you connect it, and every score arrives with the evidence attached.
We already analyse every interaction with CallMiner. What does Kaizo actually add?
Two things, and neither is more volume. First, trust: every Kaizo score links to the exact evidence in the transcript, so an agent who disputes a score gets an answer rather than an argument. Their own reviewers concede transcription errors on complex accents that affect sentiment accuracy, and sentiment that feeds a scorecard has to be defensible. Second, follow-through: Kaizo turns each scored conversation into a per-agent coaching card automatically, which is exactly the gap one of their own coaching users names when they say there is not enough AI in the coach platform. Analysis you cannot act on is a report, not a QA programme.
Will the AI actually be accurate on our conversations?
Accuracy is the one thing you should not take on faith from any vendor, including us. Kaizo connects to your knowledge base and internal tools so the AI evaluates against what your business actually knows, and every score links back to the evidence in the transcript so you can check it. Teams start at an automation rate they are comfortable with and turn it up as trust builds. The failure mode to avoid is the one their reviewers describe from the other side: an AI capability that is a bit behind, checked by hand. If your team ends up re-reviewing the AI, you have simply bought a second QA queue. A search engine that finds phrases is not the same thing as a system that judges a conversation.
Do we need analysts to build categories and syntax?
Not with Kaizo, and this is the quiet cost of the incumbent model. Their reviewers hand-author category syntax, ask for the system to flag duplicate syntax while they build it, and call renaming and refiling categories tedious. Administrators outnumber everyday users on their G2 profile, which tells you who the tool is really for. Kaizo has no query language: you define the scorecard in the words your business already uses and Autopilot scores against it. UiPath ran their programme with 100% of QA automated, because the people who used to feed the tool went back to improving the operation.
Our coaching already runs inside the platform. Is Kaizo’s coaching really different?
Ask your supervisors who writes the coaching content today. On CallMiner, the honest answer from one of their own coaching reviewers is that there is not enough AI in the coach platform, which means the analysis and the write-up are still a manager’s evening. Kaizo generates the coaching card per agent from that agent’s own conversations, with the supporting evidence already attached. EverHelp cut coaching prep by 75% across 16 domains. Coaching stops being the thing that gets skipped when the queue is busy.
What happens when our AI agents start handling conversations?
This is where neutrality stops being a talking point. CallMiner markets voice-first virtual agents and the monitoring of AI automation on the same platform, which means the tool scoring the AI conversation is sold by the vendor that shipped the AI. Kaizo does not sell AI agents, so we can score a human conversation and an AI conversation on the same scorecard with nothing to protect. As your mix shifts from human to hybrid, that neutrality is what keeps the quality number credible to your leadership.
