From empty study to in the field in one sitting.[1]
Build the study from any methods, add the screener and consent, launch it and send one link. Launch the sample study and watch its first three sessions arrive.
30 study-days free. No card.
Draft. Launch the study to open it to participants.
One sitting: a study built from blocks, a screener, consent, a launch and a participant link. The sample study is real product with sample sessions; one second here stands in for a day in the field.
Build it from any methods.
A study is a stack of blocks. Put a Figma test, a SUS and an IAT in the same study and the same participants do all three, so the scores sit beside the sessions they came from.
The screener, the consent form and the client's NDA are blocks too. Everyone who joins lands on the study's participant list with their screener result, what they signed and whether their incentive is paid.
Share one link.
Participants open it in the browser they already have, with no account and nothing to install. A pre-flight check finds a blocked microphone before task one, not halfway through it.
Every screen carries your logo and colour. On phones, recorded tasks use the phone's own screen recorder and an upload; native apps aren't tested through an SDK.
Results land processed.
A recording arrives transcribed, speakers labelled, with the transcript following the video. A method without a recording arrives scored: an IAT comes back with D-scores, exclusions and the algorithm named.
Stroop is the all-in-one research and testing platform. Run usability tests, prototypes, surveys, tree tests, diaries and IATs in one study, and get results back transcribed, scored and charted, with every finding linked to the session it came from.
Analyse and share without exporting.
Ask where people hesitated and every sentence of the answer cites the session and second behind it. Themes count who said it and keep the evidence against. The client gets a page in your brand.
How citations workClosing a study fixes its cost.
The close dialog gives the final figure before you confirm it: 9 days, $81. Those days go on the workspace's statement for the month, ready to rebill.
Set a close date at launch, and if a live study gets no new responses for 3 days, Stroop emails its owner.
