OPSY

An interviewer in your pocket

OPSY is a research interviewer that runs entirely on your device. Share an experience in your own words and contribute to citizen science — privately.

Talk or tap

An AI interviewer asks adaptive follow-ups and shows tappable rating scales. Answer by speaking, typing, or tapping — whatever feels natural in the moment.

Your data, your control

  • Pseudonymous — never your name, just a random ID.
  • Encrypted on this device — nothing leaves unless you choose to export it.
  • Export anytime — take your data as JSON or CSV.
  • Erase anytime — delete everything in one tap.

A companion over time

Browse signed, verified studies. Each shows exactly what it asks before you begin, and you control when to start, pause, or stop. Come back later to check in, and watch how an experience settles.

Log an experience
