ANKRAFeynman mode
Pick a topic, explain it out loud or in writing, and Ankra grades you on what you actually understand. Then it turns your gaps into cards that stick.
Your grade
Ankra reads your explanation and scores it like a tutor would, point by point.
Photosynthesis
Strong, with 2 gaps to close
Talk it through or write it out, like you're teaching a friend. No notes.
Get graded on what's right, what's wrong, and what you missed.
Spin up a review deck that targets exactly what tripped you up.
Close the loop
Ankra turns each thing you missed into a spaced repetition card, so it sticks for good.
The Calvin cycle
You never mentioned it in your explanation.
What happens in the Calvin cycle?
CO₂ is fixed into glucose using the ATP and NADPH made in the light reactions.
The science
The Feynman Technique isn't a study hack. Every step of Ankra's loop is one of the best-tested effects in cognitive science.
Students prompted to explain material in their own words understood it far better, and applied it to new problems more successfully, than students who simply read it again.
Chi et al., 1994 · Cognitive ScienceLearners consistently overestimate what they know while studying. Rereading feels like knowing, and the illusion only breaks when you're actually tested.
Koriat & Bjork, 2005 · Journal of Experimental PsychologyA week after studying, students who tested themselves remembered substantially more than students who spent the same time rereading the material.
Roediger & Karpicke, 2006 · Psychological ScienceA landmark review of ten study techniques rated practice testing and spaced practice as the two most effective, and rereading among the least. Ankra's loop is built on the top two.
Dunlosky et al., 2013 · Psychological Science in the Public InterestTeaching is the fastest way to learn. Ankra makes it a habit.
