Show HN: Prepform - AI and spaced-repetition to optimize learning
Hi, I'm Eric and I'm the founder and lead developer of Prepform. A
high-quality education helped me pursue my interests and achieve my
goals. I started Prepform so students of all backgrounds have
access to the same kind of education. I grew up in Southern
California, surrounded by dozens of SAT prep programs, and I swear
I must have gone to all of them. Different programs followed
different styles and techniques, but the strategy they shared was
to create a study plan and review mistakes. A study plan is taking
a diagnostic test, setting a target score, creating a study
schedule, identifying mistakes, and finally reviewing those
mistakes. I wanted to take this structure and optimize it with
machine learning, while accounting for elements of human learning
and memory. I'm a big fan of SuperMemo, a memorization technique
developed by Piotr Wozniak, where you review material just as
you're about to forget it. Cognitive psychology tells us human
forgetting follows a pattern, but Piotr quantified this behavior to
identify the precise moment forgetting happens. The goal was to
build on his research with AI and tailor it to not only test prep
but to the individual student, and make it the engine of the study
plan. The result is Blended Prep, which guides students to
internalize knowledge rather than memorize material, and gives them
the best chance to ace their next exam. I'm so excited to share
this with the HN community, and would love to know what you think.

| My kids use DuoLingo and Khan Academy for learning and their

| that's not accurate?
|
| Some feedback on the site:
|
| 1) I'd suggest replace "Remember everything" with something less
| absolute. I don't that's a realistic goal and had me doubting the
| rest of what I was reading. Humans forget sometimes and that's
| OK.
|
| 2) A lot of words were underlined. I thought they were links.
|
| Good luck with your business!

| Thanks! My learning philosophy is that the bulk of learning

| topics they missed, and answer 3 questions about their
| mistakes: "What did I do wrong?", "What should I have done
| instead?", and "What is the clue in this question that I
| missed?".
|
| This "mistake log" will use spaced-repetition to show their
| mistake just as they are about to forget it. I think this is a
| huge missed opportunity for companies like Duolingo and Khan
| Academy. My goal is to guide students through a study plan, so
| they know what to study and for how long.
|
| I appreciate the feedback!

| 1. Good that you can try it out without signing in.
|
| 2. Bad that the screen where you select the things is so

|
| 3. Bad that the maximum # questions is 0, even though I've chosen
| options that have questions (see screenshot)

| Thanks for taking the time for the screenshot and highlighting!
| I'll look into the bug.

| I can't tell the difference between radio buttons and

| Agreed. It's nice to have fresh eyes looking at the site.
| Thanks!
