Case study: read how designers are saving days of time using Thematic Lens as their user research summarizer
The product design team at Agency X had recently completed a series of 12 in-depth user interviews as part of a research project to understand user behavior and satisfaction with a newly launched product feature. The interviews spanned multiple topics, but processing these transcripts for themes would have taken days to complete manually, delaying crucial design iterations.
The team uploaded all 12 interview transcripts into Thematic Lens as their user research summarizer. The app’s automated thematic analysis quickly identified key patterns, recurring themes, and sentiment variations. Within seconds, Thematic Lens delivered a summary that highlighted user needs, pain points, and satisfaction insights, providing both qualitative and quantitative insights.
By using Thematic Lens, the team saved an estimated 12–15 hours of manual data analysis, reducing what would have been several days of work into a few seconds. The final report was shared with team members and stakeholders within minutes, allowing them to align on actionable insights right away.
“Thematic Lens is amazing. Summarizing 12 transcripts would have taken days, but we had the entire analysis done in seconds. The visual breakdown made it easy to understand user feedback at a glance.”
