What is user testing software?
User testing software lets product, UX, and research teams observe how real users interact with a product, prototype, or website. Also called user experience testing software or UX research tools, it captures what users do, say, and with Decode what they actually feel through emotion AI and eye gaze tracking.
How does Decode's AI moderator run user research sessions?
Decode's AI moderator, Mira, handles the full moderated interview session autonomously. It introduces tasks, asks follow-up questions based on how participants respond, and adapts its line of questioning in real time when it detects hesitation or confusion through emotion AI. Participants join via browser no moderator scheduling, no script rigidity. Every session is automatically transcribed, emotion-tagged, and summarised into a report. Most teams go from study setup to shareable insights in under 48 hours.
What is the difference between moderated and unmoderated user testing?
Moderated user testing involves a live session where a moderator (or Decode's AI, Mira) guides the participant through tasks and asks follow-up questions. Unmoderated user testing lets participants complete tasks independently, on their own schedule, without a live facilitator. Both are available in Decode. Moderated is better for deep qualitative insight; unmoderated is better for scale and speed.
How does remote user testing work?
Remote user testing lets participants complete research sessions from their own devices, anywhere in the world no lab required. With Decode, participants join via any browser. The platform captures screen recordings, behavioral data, eye gaze (via webcam), and emotion signals automatically. Most studies return insights within 48 hours of launch.
What does Decode capture during a user research session that other tools don't?
Beyond clicks and task completion, Decode captures three additional data streams most user testing software cannot: webcam-based eye gaze tracking (where users look, fixate, and scroll past), facial emotion AI (detecting confusion, frustration, delight, and surprise in real time), and voice emotion analysis (picking up uncertainty and hesitation in spoken responses). These signals are layered directly onto session recordings and reports so instead of guessing why a user abandoned a flow, you can see exactly what they were feeling at that moment.
How quickly can I get results from a Decode user research study?
Most Decode studies return full insight reports within 48 hours of launching including auto-transcripts, emotion heatmaps, gaze paths, and an AI-written summary of key findings. Unmoderated studies can run in parallel across hundreds of participants simultaneously, so scale doesn't slow you down. Setup typically takes under 15 minutes. There's no transcription queue, no manual tagging, and no waiting for a research analyst to process recordings.
Is there a free trial for user testing software?
Yes Decode offers a free sign-up with no credit card required. You can run your first user research study and explore core testing methods before committing to a plan. For enterprise teams, a live demo is available to walk through the full emotion AI and behavioral analytics capabilities.
No hardware. No scheduling chaos. No 3-week wait for insights.
