Senaste vs Synthetic Users: what each one tests

Synthetic Users runs AI interviews and surveys with synthetic participants, sold as an annual research plan. Senaste sends AI personas through your live website on a task, paid per persona. One answers why people want something; the other, where they get stuck on your site.

Checked on 5 November 2026 against the public pages of Synthetic Users.

Synthetic Users fits better if

  • You need interviews, surveys, concept tests, card sorts or tree tests, not a walk through a site.
  • A research team runs many studies a year and wants an annual plan with unlimited seats.
  • Procurement asks for SOC 2, a data processing addendum and EU data regions.
  • You want to feed your own research documents into a study.

Senaste fits better if

  • You want to see where people get stuck on your live site, step by step, with screenshots.
  • You want to start with a few dollars, not an annual contract.
  • Your pages should stay on servers the service runs itself, not go to public AI services.
  • You want a fix file for an AI coding tool and an SEO check of the pages your visitors opened.
