Can a QA Tool Score Your AI Agent, Not Just Your Humans?

Every QA platform in this category advertises scoring 100% of conversations. For years that meant one thing: reviewing what human agents did, instead of sampling three tickets a week.

Then tier-one moved to software. If an AI agent handles half your volume and your QA tool only grades humans, your coverage did not go up. It halved.

QA is the one category here that mostly does not act

This directory classifies every platform by whether it can change something in a system of record. QA is the only category where that is the minority answer — most of these tools grade, flag and coach, and the only thing they write is a score on a ticket.

That is not a criticism, it is the product. But it means the buying question is different: you are not asking what it can do to a customer, you are asking what it can see, and what it quietly skips.

Read the exclusions under the coverage claim

Zendesk QA is the clearest example of why the headline number needs reading twice. Its 100%-of-conversations claim carries exclusions that appear only in the documentation: a conversation needs a message from both sides and a minimum of ten words, spam and historical conversations are skipped, and a newly created category applies only to conversations that arrive after it exists.

None of that is unreasonable. All of it changes what 100% means, and none of it is on the marketing page.

The vendor publishing evidence against its own automation

MaestroQA is worth crediting because it argues against itself in public. Its own guides say AutoQA suits low-variance questions with minimal back-end dependency, that knowledge and resolution questions still need human oversight because they vary with context, and — in its own words — that AutoQA is not a shortcut to eliminating manual QA processes.

It also publishes poll figures that cut against the product it sells. In its own webinar polls, 94% of CX professionals said the whole conversation still needs manual review, and 68% do not expect AutoQA to do back-end checking. That last number is the useful one: it is a statement about what automated grading cannot see, published by a company selling automated grading.

Treat those as polls rather than a survey — there is no sample size published anywhere — but a vendor putting them on its own site is doing something the rest of this category does not.

Who actually grades the bots

EvaluAgent ships a separate product for it, AI Agent Observability, and its pitch is the cross-vendor angle: reporting that grades Cognigy, Sierra, Decagon and your humans against the same definition of quality. That is the right shape for the problem, because most teams will end up running an agent from one vendor inside a help desk from another.

MaestroQA grades AI agents through Ada and Agentforce connectors. Level AI grades bot conversations too — and is the case study in why this category moves quickly: it now sells a customer-facing virtual agent of its own, which is why we reclassified it this year from a tool aimed at humans to one that acts.

Observe.AI is the odd one out and the most interesting. It grades, it advises agents in real time, and it also resolves calls through its own voice agents. Which means its Auto QA can score its own autonomous agents alongside the humans — one platform holding three different relationships to the same work.

The question this category is actually about

If an AI agent gives a customer a wrong refund policy at 2am, who notices? Not the customer, who believed it. Not the agent, which has no opinion. Not your CSAT survey, because the customer was satisfied with a confident wrong answer.

That is the gap these tools are moving into, and it is why the grading question is worth asking before the volume moves rather than after. The one thing to establish in a demo: can it score a conversation no human ever touched, and can it do that for an agent you bought from somebody else?

Read from each vendor's own documentation and published material. Figures a vendor publishes without a population are recorded as such rather than repeated as benchmarks.

I read the fine print. Vendor pricing pages, billing definitions, terms, funding filings and acquisition notices — then I do the arithmetic nobody publishes: what a platform actually costs at your volume, what its headline metric is really counting, and who owns it now. I do not run benchmarks, and no page here pretends otherwise.
