Both Synthetic Users and Buyer Clone use AI to replace slow, expensive human loops — but they sit at different stages of the funnel and answer different questions.
What each one actually does
Synthetic Users is an AI user-research platform. You define an audience, write a topic guide or script, and run a “study” where synthetic participants — given stable OCEAN personality profiles and optionally grounded in your own data via RAG — respond as interview subjects. It supports problem exploration, concept testing, custom scripts and large surveys, and honestly frames itself as a “discovery co-pilot, not a replacement for real research.”
Buyer Clone is a pre-launch conversion tool. You paste a URL, and a panel of AI buyer-persona agents moves through your actual landing page, reporting where each one stalls, doubts, or converts, and returns a ranked conversion brief in minutes.
The core difference
Synthetic Users answers upstream questions — what problem matters, which concept lands, what message resonates — through simulated interviews. Buyer Clone answers a downstream question — does this specific page convert, and where does it leak — by simulating buyers walking the page. It’s research vs conversion, not better vs worse.
Where Synthetic Users is genuinely stronger
For actual research rigour, Synthetic Users goes deeper: structured study types, personality-stable participants with continuity across interviews, RAG grounding in your own customer data, and a candid, academically-referenced posture about what synthetic research can and can’t do. If your question is “what should we build or say?”, that’s the right apparatus.
The honest take
Use them together. Synthetic Users to sharpen the message and concept early, then Buyer Clone to test whether the page you built around that message actually converts — before a single visitor lands.
