Catch voice-agent failuresbefore your customers do.

Preflight tests your AI voice agent against real-world customer scenarios and shows you exactly where it fails before you ship it to a client.

No setup required. Send us the agent and its rules. We test it and send back the failures, transcripts, and results.

01 What we test

What happens when real customers call?

We test the ordinary calls that should work, the edge cases that usually break, and the business rules your client expects the agent to follow.

01

Booking & task completion

Can the agent actually complete the customer’s request?

PassEmergency booking → Completed
02

Business rules & pricing

Does it follow hours, service areas, approval limits, and pricing rules?

PassAfter-hours request → Correctly handled
03

Escalation

Does it recognize when a human needs to take over?

PassNo-heat emergency → Human notified
04

Tools & integrations

Does it recover safely when connected tools fail or return unexpected results?

PassCalendar conflict → Safe recovery
05

Messy conversations

Does it stay on track through interruptions, missing information, and confused callers?

PassCaller interrupts → Context preserved
06

Boundaries & adversarial behavior

Can callers pressure the agent into doing something it should not do?

PassRule override request → Refused

02 Sample Release Check

One page should tell you what failed and what to fix.

Every failed scenario includes severity, expected behavior, what the agent actually did, and transcript or recording evidence. After you update the agent, we retest the failures once.

Every client deployment introduces different prompts, business rules, integrations, and edge cases. Preflight gives you an independent release check before you hand the agent over.

01

Catch embarrassing failures

Before the client’s customers do.

02

Ship with evidence

Show clients that the agent was tested before release.

03

Retest after changes
