Placement first
Each check names its moment: "After 1:42": and the reason that moment earns a confirmation.
Research on in-video questions shows that retrieval practice can improve retention. A learner recalls a point soon after learning it, so the placement of a check can matter more than the number of checks.
A well-placed check sits immediately after the content it confirms, while the concept is still in working memory. A badly placed one interrupts mid-explanation, or tests something taught three minutes earlier. This tool reads the structure of your transcript and places each check at the seam after a concept completes.
The reasoning line on each check: why this moment: is there so you can disagree. If a moment does not deserve the interruption, drop the check. The frequency setting exists for the same reason: compliance training tolerates frequent confirmation; a marketing walkthrough does not.
Inside Mindstamp, a check does more than pause the video. A wrong answer can replay the section that taught the concept, and every response is recorded per learner, so the checks double as evidence of understanding.
