Tadeus vs Conveo (2026)
Tadeus and Conveo both replace the human moderator with an AI agent, but they sit on opposite sides of one design decision: the camera. Conveo is video first, built to capture voice, video, and text together for brand and consumer insight teams. Tadeus is voice only, built for employees, workforce populations, and platforms that embed interviews via API.
Quick answer: Choose Conveo for consumer and brand research where participants are happy on camera and emotional cues add signal. Choose Tadeus for employee and workforce research, for participants who will not turn a camera on, or when you need to embed interviews in your own product and stay clear of the EU AI Act emotion-inference line.

What Conveo does best
Conveo runs the full qualitative workflow in one place: design the study, recruit, interview, analyse, and share. Its AI moderator captures voice, video, and text together, reads tone and emotional cues, and probes for depth. The company reports that most final insight comes from AI-driven follow-ups rather than the scripted questions, which is a strong signal that the live moderation works. It is built around established market-research frameworks, so insight teams get outputs in a familiar shape.
If you run brand, concept, or consumer studies and want video depth, Conveo is a strong choice.
What Tadeus does best
Tadeus deliberately removes what Conveo leads with. There is no camera, no video capture, and no emotion inference from voice tone. 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. It works from transcripts and retains no audio.
That trade-off wins in three situations:
- Employees. The EU AI Act prohibits inferring emotion in the workplace from February 2025. A video-first tool that reads emotional cues is a compliance risk in workforce research. Tadeus was built without emotion inference to stay clear of that line.
- Camera-off participants. Frontline workers, drivers, field staff, and anyone answering from a phone or between shifts will often not turn a camera on. Voice-only removes that barrier.
- Embedding. Tadeus ships a REST API with webhooks so platforms can run interviews inside their own software rather than sending users to a separate app.
How to decide
- Brand, concept, or consumer insight with willing on-camera participants: Conveo.
- You want one platform to design, recruit, and share consumer studies: Conveo.
- Employee or workforce research: Tadeus. Voice only and no emotion inference keeps workplace deployments compliant.
- Your participants will not turn on a camera: Tadeus.
- You want interviews inside your own product: Tadeus, via the API and webhooks.

Frequently asked questions
Is Tadeus or Conveo better for employee research?
Tadeus. It is voice only, retains no audio, and does not infer emotion, which is the main EU AI Act concern when interviewing employees. Conveo is video first and reads emotional cues, which suits consumer research rather than workforce research.
Is Tadeus or Conveo better for consumer research?
Conveo. It covers the full consumer study workflow with video depth and market-research frameworks. Tadeus does not target consumer insight and does not recruit participants.
What if participants refuse to be on camera?
Tadeus is voice only, so there is no camera to refuse. Voice-only interviews also lower self-consciousness, which can increase how much people disclose.
