Tadeus vs GetWhy (2026)

Tadeus and GetWhy both run AI-moderated interviews, but they are built for different audiences. GetWhy is a consumer and market research platform with video interviews and a large recruited panel. Tadeus is a voice-only interviewing platform built for employees, workforce populations, and platforms that want to embed interviews via API.

Quick answer: Choose GetWhy for large-scale consumer studies where you need participants recruited for you and video adds signal. Choose Tadeus for employee and workforce research, or when you need to embed interviews inside your own product, keep to voice only, and stay clear of the EU AI Act emotion-inference line.

What GetWhy does best

GetWhy is built for consumer insight at scale. It runs AI-moderated interviews in over 100 languages, recruits from a panel of more than 300 million participants, and applies multi-step automated quality assurance scored against a documented 17-criteria framework. Its analysis draws on models fine-tuned on over a million interviews, and it captures text, audio, and video so researchers get rich signal from every session.

If your question is about consumers, brands, or markets, and you need participants sourced for you, GetWhy is one of the strongest platforms available.

What Tadeus does best

Tadeus is defined by what it leaves out. It is voice only, with no video and no emotion inference from voice tone. It works from transcripts and retains no audio. An AI agent holds a spoken conversation in over 70 languages, probes and branches on answers, can verify identity or call external systems mid-conversation, and returns a transcript plus structured JSON.

That design serves two use cases GetWhy does not target:

  1. Employee and workforce research. The EU AI Act prohibits inferring emotion in the workplace from February 2025. GetWhy’s moderator reads tone and hesitation, which is an asset in consumer research but a compliance risk when the participants are employees. Tadeus was built without emotion inference so workplace deployments stay clear of that line.
  2. Embedding. Tadeus ships a REST API with webhooks so platforms, such as HCM and workforce software, can run interviews inside their own product instead of sending people to a separate app.
