Feynman mode
Feynman Technique App
Find the gaps in what you know. Explain a topic in your own words, get AI feedback against your study material, then turn the gaps into flashcards.
Your grade
Know exactly where you stand
Ankra reads your explanation and scores it like a tutor would, point by point.

How it works
You talk. Ankra listens and takes notes.
Explain it
Talk it through or write it out, like you're teaching a friend. From memory, no peeking. Pick any topic, use one of your notes, or upload a PDF, slides, photos, or a recording as the source.
See your gaps
Get graded on what's right, what's wrong, and what you missed.
Turn gaps into cards
Spin up a review deck that targets exactly what tripped you up.
Close the loop
Every gap becomes a card
Ankra turns each thing you missed into a spaced repetition card, so it sticks for good.
Direction of diffusion
Your explanation did not say which way particles move.
In which direction do particles move during diffusion?
From a region of higher concentration to a region of lower concentration.
The science
Backed by decades of research
The Feynman Technique isn't a study hack. Every step of Ankra's loop is one of the best-tested effects in cognitive science.
Explaining deepens understanding
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 ScienceYou can't feel your own gaps
Learners 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 PsychologyTesting beats rereading
A week after studying, students who tested themselves remembered substantially more than students who spent the same time rereading the material.
Roediger & Karpicke, 2006 · Psychological ScienceThe two best techniques, combined
A 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.
