ProofPilot works best when you start the planning process on the platform and launch the study to participants from the beginning. But it can and has been added to studies already in process.
If your study is already in progress and you would like to use ProofPilot for any new participants who will be recruited into your study, set up your study as usual. Once you launch the study, direct any new participants to your study recruitment page and engage them through ProofPilot.
Currently, there are no tools to import participants and data.If this is something you would be interested in, please let us know by upvoting the in-progress study data in the upload feature request. It is in the community forums.
