You grade it
Grade AI's work yourself. If you can't tell mediocre from excellent, you haven't learned it yet.
Progress you can feel
XP and streaks instead of timed exams. Your latest work is your grade — growth, not accounting.
Tutoring works.
It never scaled.

percentile, Bloom's tutored students
In 1984 Bloom put one tutor with one student. Those students finished two standard deviations above the classroom. Nobody can hire that tutor 30 times per room. Gilbert is that tutor, every lesson.

Quotes you
A skill is checked off with a quote of what you said. No quote, no check.

Remembers you
One skill note and one preference per turn. The next lesson starts there.
Brings it back
Checked-off skills return weeks later, right before you would forget them.

FAQ
Frequently asked questions
Is Gilbert free?
Yes. Every lesson is free to learn. Getting a course on your transcript as a credit is a separate step, covered on How it works.

Can I talk to him?
