Psychological tests, tasks and questionnaires — online.

Brainelli hosts validated psychological instruments you can run in the browser. Approved researchers create studies, generate single-use subject links, and access per-subject results from their account. Anyone with an account can try instruments themselves and — if they opt in — contribute anonymized data to a shared pool for secondary analysis. The first instrument live today is the Cognitive Bias Task (Goldberg, Podell, & Tulviste, 2026); more are on the way.

Step 1

Create an account

Sign up to try instruments yourself, or request researcher access — an administrator reviews researcher requests before approval.

Step 2

Pick an instrument

Researchers choose an instrument and configure the study (conditions, target subject count, optional questionnaires).

Step 3

Invite subjects

Generate N single-use links and share them with participants. Subjects complete the instrument online — no install required.

Step 4

Get your results

View per-subject reports and download anonymized CSV exports from your account. With consent, data contributes to a shared pool for secondary analysis.
