What is the difference between Persona and Strella?

Persona offers voice call, chat, and video modalities, embeds directly into your product, and includes a dedicated AI for churn research with quality-gated billing. Strella offers AI-moderated text and video interviews on a standalone platform with an optional switch to human moderation.

Does Persona or Strella support human moderation?

Strella offers the option to switch between AI and human moderation. Persona is AI-first with no human moderation option, but provides a voice call format that consistently drives higher completion rates than video-first tools.

Which platform is better for churn and retention research?

Persona has a dedicated AI trained specifically on cancellation conversations that probes deeper and can make personalised win-back offers mid-interview. Strella is a general-purpose AI interviewer with no specialisation for retention workflows.

Persona vs Strella: which AI research platform is right for your team?

For years, the hardest part of customer research wasn't analysis, it was logistics. Scheduling interviews, chasing participants, transcribing hours of conversation. AI interview platforms promised to fix that, and largely have. But as the category matures, a more interesting question has emerged: not whether AI can run an interview, but whether it can run the right one.

Why teams choose Persona

🚀

In-product interview deployment

The best time to interview a user is in the moment, when they're cancelling, onboarding, or hitting friction. Persona embeds directly into your product via a code snippet, so the conversation happens in context, not days later on a third-party platform.

🎥

Voice, chat, and video modalities

Persona offers voice call, chat, and video. The voice format — designed to feel like a natural phone call, consistently drives higher completion, particularly in B2B and mobile contexts where turning on a camera is a barrier.

📊

Cancellation and retention intelligence

When someone says "too expensive," Persona's cancellation-focused AI probes further — what they expected to pay, what would have changed their mind, and whether an offer mid-conversation could save them. It's the difference between logging a reason and acting on it.

💸

Quality-gated billing

Persona runs post-interview AI checks against your own criteria and only charges for responses that pass. At scale, that changes the economics of research significantly.

📖

Centralised company knowledge

Persona's knowledge hub carries your brand voice, product context, and prior research into every new study. Discussion guides start with information. Reports don't read like they were written for a stranger.

🗣️

Conversational results interface

Beyond reports and reels, ask any question about your data in plain English and get a direct answer with the supporting video clips attached.

Run churn and retention research and want an AI purpose-built for those conversations
Want the interviewer to reflect your brand, not the platform's
Want to only pay for responses that meet your own quality criteria
