Use the pre-call form to qualify participants by role, product usage, and demographics before the interview.

Ask exploratory questions and follow-up probes using Burst nodes configured for UX research.

Push verbatim responses and sentiment tags to your research repository in real time.

Probe deeper when a participant mentions a pain point using conditional IfElse branching.

Generate a structured insight report per participant and push it to your team automatically.

Flag participants for a follow-up deep-dive and route them to a researcher via SIP Transfer.

Spin it up. Call it. Refine until it’s right.

Describe the voice agent you want, like 'Build a pitch practice bot', and the AI creates the full conversation flow instantly.

Drag, drop, and connect nodes to reshape the conversation flow exactly how you want it.

Describe what you want to change in plain language and watch the agent update in real time.

Talk to your agent right inside the builder - no deployment needed.

When the agent says something off, click on that message in the conversation panel to correct it.
