Keep the subscribers you have. Win new readers. Kouiz is a short, editor-approved quiz on a story’s key concepts, placed at the end of the article, with friend challenges that bring new readers to your own site.
Kouiz is an early concept with a working prototype. It has no customers, results or certifications yet.
Read → Understood → Locked in
Five short steps after the last paragraph. It runs inside your page, under your masthead, behind your paywall.
- Quiz
Kouiz the key concepts
A few questions on the story’s key concepts, answered from memory. Every question is editor-approved and grounded in a quote from the story.
- Try again
The why, then Try again
Each answer shows why, with the sentence it comes from. Miss one and Try again, with the answers reshuffled, so it is recall rather than position.
- Score
Your score
A concept checklist, spoiler-free squares and an opt-in share.
- Locked in
“Still remember?”
The next day, a quick check on the concepts that slipped. Pass it and they’re Locked in. No rereading needed, and a reason to come back.
- New readers
Kouiz a friend
A challenge link to read the same story on your site. You vs. Them at the end, then Kouiz them back.
Every challenge brings a new reader to your own site.
Sharing is opt-in and spoiler-free. The link leads to your article on your domain, not to us.

The quiz is the feature. The closed loop is the product.
Kouiz measures what each story does for retention and comprehension, and where new readers come from. The panels below show the planned layout. They contain no real data.
Kouiz retention score
Return visits and renewals of Kouiz readers, measured against a randomized holdout of readers who never see the quiz.
Comprehension data layer
For every story, which concepts readers grasp, which they miss on the first try, and which they forget by the next day.
Challenge funnel

Built on well-replicated learning science
Recalling something from memory makes it stick better than rereading it (Roediger & Karpicke, 2006). Seeing the right answer right after a test strengthens that effect (Butler & Roediger, 2008), and spacing the next check makes it last (Cepeda et al., 2006). Kouiz puts all three at the end of the story. These are findings from learning research, not results from Kouiz. Measuring Kouiz’s own effect is what the pilot is for.
Read the story. Take the Kouiz.
The working prototype on a sample article page from a made-up paper, The Demo Daily, using a public-domain NASA news release. Scroll to the end of the article to reach the Kouiz. Miss one to see Try again, then come back later for “Still remember?”.
The demo is a prototype, not a shipped product. It uses an anonymous, random reader ID stored in your browser; no names, emails or IP addresses are kept. Article: NASA, “NASA Science, Cargo Launch on 35th SpaceX Resupply Mission to Station” (Oct. 13, 2026), public domain. NASA is not affiliated with Kouiz.
