The problem
A real 1:1 tutor works. Almost nobody can afford one.
Private tutoring is priced by the hour, matched to a real person's schedule, and out of reach for most students preparing for a course, an entrance exam, or an interview. Generic AI chat fills the gap with answers, but answers you can copy aren't the same as understanding you've earned.
The mechanism
It doesn't just answer. It makes you prove it.
Teach it back
Before we move on — explain, in your own words, why the induction step needs the base case at all.Not quite
Getting there — the base case is what anchors the whole chain to something you've actually proven, not assumed. Try again.Nailed it
Nailed it. That's the difference between reciting a proof and understanding one.What's coming
Everything is built around actually learning it.
Teach-back tutoring
Flocus doesn't just answer. It asks you to explain the concept back in your own words before moving on — the same thing a good human tutor does.

Concepts resurface right before you'd forget them, not on a fixed calendar — spacing your review is proven to beat cramming.

Flocus tracks how you learn best, what's worked for you, and what's worth double-checking — and adjusts pacing accordingly.

Built on how memory actually works, not vibes.
Spaced review
Spacing practice over time consistently outperforms cramming for long-term retention (Cepeda et al., 2006, spacing-effect meta-analysis).
Retrieval > re-reading
Being asked to recall or explain a concept builds stronger, more durable memory than passively re-reading it.
Teach-back
Explaining a concept back in your own words is one of the most reliable signals that you've actually understood it, not just recognized it.
