Behavioral evaluation for conversational AI

AI agents that talk to your customers will fail in ways you haven't tested for.

Luku finds the gaps before your customers do.

74%

Critical majority

Already rolled back an AI customer communications agent as a data leak or bad response discovered only after it reached real customers.

Sinch — "The AI Production Paradox," 2026

Enterprises aren't discovering these problems in testing — they're discovering them in production, from real customers.

What we do

We find the gaps, before your users do.

and growing with every evaluation

From dozens of test cases to thousands

Manual QA covers a handful of scripted conversations. Luku runs each scenario across hundreds of variations — different phrasing, different pressure points, different people — so you're not just checking that the happy path works.

Process

How it works

  1. 01

    Configure the evaluation.

    Define the scenarios, risks, and personas that matter for your product. Set the coverage and depth of testing.

  2. 02

    We run the evaluation.

    Tests are executed against your AI agent.

  3. 03

    Get a list of findings.

    Findings and vulnerabilities, scored by severity, ready to prioritize — and usable as evidence for compliance reviews or sales conversations.

  4. 04

    Re-evaluate automatically.

    Your behavioral regression suite that is triggered by model updates, new features, pipeline changes, new users, or new use cases.

Compare

How teams currently catch this — and how they don't

Little to no testing

What you get

scattered manual checks, not systematic coverage — gaps you find out about when a customer hits them

Cost

looks free — until a rollback, a bad headline, or a compliance question you can't answer

What's missing

no coverage against the scenarios, risk or user types you didn't think to test, no early warning, no evidence trail

Build it in-house

What you get

some coverage — but only against the scenarios, risks and user types you thought to build a taxonomy for

Cost

a dedicated team of AI and compliance specialists, plus ongoing upkeep every time a model, prompt, or feature changes

What's missing

independence — you're still grading your own homework. And depth — testing isn't your core product, so coverage lags behind the risks you didn't think to look for

Luku

What you get

continuous evaluation across 100+ risk patterns and thousands of test dialogues — coverage you didn't have to build yourself, and evidence your sales, marketing, and compliance teams can actually use

Cost

scoped to the depth of testing you configure — no hiring, no upkeep

What's honest to flag

you're granting an outside evaluator access to your agent — which is exactly the independence that makes the findings credible in the first place
