Interactive voice AI case study

PD Voice Agent

Describe a product idea. The agent asks five follow-up questions and produces an evidence-based review of the concept, not of you.

The agent speaks German only. The interface and review are available in English.

Before you start

The call needs your microphone. Voice transport runs through LiveKit in the German region. The transcript is then evaluated by an Anthropic language model in the United States. Nothing is stored: no audio, transcript, or review. Everything disappears when you leave the page.

Please use a fictional or non-confidential product idea and do not share personal, secret, or commercially sensitive information.

I have read this and want to start the conversation.

Conversation

The conversation appears here word by word while it runs.

Concept review

After the call ends, a structured evidence-linked review appears here.

A short conversation turns the problem, audience, existing evidence, open assumptions, and next validation step into a structured review.

Problem, audience, and frequency
Current alternatives and their limits
Existing observations, interviews, or data
Smallest useful solution and dependencies
Riskiest assumption and cheapest seven-day test

How this is built

One architecture, two separate trust zones

The live demo follows one path. The web gateway and public API limit access; the voice worker knows neither the browser secret nor stored conversation data.

What is actually evaluated

The review assesses the idea described in the conversation and links claims back to transcript evidence. Missing support is shown as not assessable instead of being replaced with a plausible number.

Evidence quality
Solution scope

This project started as an HR voice agent. The original recruitment system and its AI Act redesign remain in the monorepo as a historical case study, but no longer power a live path.
