Why this works
letsgye is not a video player with a quiz bolted on. Every part of it is built on settled learning science. Here are the five ideas it leans on, in plain language, each linked to where it is actually working in the product.
Memory fades on a predictable curve
Without review, what you learn decays quickly and along a regular curve. letsgye schedules each review against your own curve, resurfacing a concept just before you would forget it instead of long after.

Retrieving an answer from memory strengthens it far more than re-reading the same page. So the checks and reviews make you recall, not re-skim, because the effort of recall is what builds the memory.
Try retrieve vs rereadThe harder way is the durable way
Spacing practice out and mixing topics feels slower and harder, yet it builds memory that lasts longer and transfers to new problems. letsgye spaces and interleaves on purpose, even though massed cramming feels easier in the moment.
Try interleavingMaster each step before the next
When learners demonstrate a step before moving on, they tend to go further than those pushed ahead on a fixed schedule. letsgye gates progress on demonstrated mastery, not time on a clock, and shows you exactly what you have proven.

Durable motivation grows from autonomy, a real sense of competence, and visible progress, not from points, streaks, or pressure. You operate the model, choose your own path, and watch genuine mastery build, with no dark patterns and nothing tracked.
