Customer understanding from A to Z

Run interviews, tests, and feedback in one flow
with AI personas trained on real user data.

Hard, tedious, but mission-critical work

Recruiting users, writing surveys, organizing notes…
UX research keeps getting pushed back when you’re busy,
but your product’s success depends on it.

Interviews & feedback collection

From recruiting participants to scheduling, recording, and summarizing, a single study can take weeks. You know it matters, but it ends up being something you can’t do often.

Validating hypotheses

“Is this flow better?” “Is this plan too expensive?” Hypotheses pile up, but there’s no time or bandwidth to check with real users—so you end up shipping on gut feeling.

Scattered data

Interview notes in Notion, surveys in spreadsheets, feedback in Slack… Just gathering and comparing insights turns into another research project.

Faster, easier customer understanding

Connect tests → interviews → feedback analysis
into one seamless flow with AI personas.

AI Persona Testing

to AI personas trained on real customer data
and get instant feedback.
See “How would this user react?” without recruiting participants.

Interview

Record interviews in real time while the AI suggests
better follow-up questions on the spot—
or generate a full interview script from scratch
for smoother, easier sessions.

Feedback

Collect feedback from in-product widgets, links, and other channels
into a single place.
Surface key insights, never miss important voices,
and spot recurring patterns faster.

Project

From problem discovery → hypothesis & simulation → evidence-based decisions,

FAQ

Does the AI persona completely replace real user research?

No. Celon AI personas are a tool for first-round validation and repetitive research work. They help you quickly filter hypotheses so you can focus real user research where it matters most.

Can we use it even without a dedicated researcher on the team?

Yes. The service is designed so PMs, designers, and founders can start using it right away. If you do have a researcher, they can spend more time on deeper, high-quality study design instead.
