Quick Verdict
Strella built a strong "speed" brand — run 100 interviews overnight with AI moderation. But their own G2 reviewers flag that AI summaries lack nuance. Decode delivers comparable speed with Emotion AI insight depth that goes well beyond what Strella can produce.
Introduction
Strella's value proposition is clear: run 100 customer interviews by tomorrow morning. For research teams that have historically waited weeks to conduct and analyse qualitative studies, that promise is genuinely compelling. Amazon, Duolingo, Square, and Nubank are among Strella's clients — a credible set of logos for a company founded in 2023.
The challenge Strella faces, however, is one their own users have surfaced on G2: AI summaries lack nuance. You can scale interviews rapidly — but if the AI analysis of 100 interviews produces outputs that feel shallow or miss the emotional undercurrents of what participants said, the speed advantage evaporates when stakeholders push for the "why."

The Nuance Problem in AI Interview Summaries
When G2 reviewers describe AI summaries as "lacking nuance," they're describing a real gap: the AI is pattern-matching on what participants said, but not capturing how they said it — the hesitations, the moments of genuine excitement, the emotional resistance behind a polite answer. These signals live in facial expressions, vocal tone, and where a participant's eyes move during stimulus exposure.
Decode's Emotion AI captures exactly these signals. Every AI moderated interview on Decode generates both a verbatim and thematic transcript summary AND an emotional response layer — showing which questions produced genuine engagement, confusion, or resistance. This is what transforms 100 fast interviews into 100 actionable insights.

FAQ
Can Decode match Strella's speed?
Yes. Decode's AI moderated interviews deliver results within the same timeframe as Strella — same-day to overnight for most studies. The difference is that Decode adds an Emotion AI layer to every interview, so you get speed AND depth rather than having to choose between them.
What do Strella users say about AI insight quality?
Strella's G2 reviews (5.0 stars on a small number of reviews) highlight speed and ease of use as strengths. The recurring limitation mentioned is that AI reporting lacks nuance and depth, and that question format customisation is restricted. Decode directly addresses both — with Emotion AI for depth and flexible interview design templates.
