PrepAtom

Measures retention, not hours

Your syllabus, on a schedule that admits how memory works.

Bring your own PDFs and your own keys; PrepAtom turns them into atomic cards, schedules the reviews, and shows you the arithmetic behind every number it reports.

One email when it opens, and the price before you are ever asked to pay. Nothing else, never shared. What we do with it.

No content sold. No selection promised.

How it works

  1. 01

    Bring your own material

    Your PDFs, your notes, your previous years' papers. We host no content and sell none — what you study is yours and stays yours.

  2. 02

    It becomes atoms

    One fact per card, tied to the syllabus node it belongs to. Write them yourself or have them drafted; either way a human checks them before they are ever scheduled.

  3. 03

    Reviews arrive when due

    Not when you feel like it, and not everything at once. The schedule is computed from how memory actually decays, and you can open the arithmetic for any card.

Coverage says you have read it. Retention says you would still know it.

Most tools count what you have done. When these two disagree, the gap is the most useful thing on the page — and it is the reason this exists.

Coverage

82 %

Weighted by what the papers actually ask, not by what the notification lists.

Retention Health

47 %

The honest "do you still know it" number, computed from the memory model.

Illustrative. Every real number opens to its formula, its inputs and a plain sentence — a number you cannot interrogate is not evidence.

What it will not do

Four things this will never grow into, however much anyone asks.

Where this is up to

PrepAtom is being built now and is not open yet. The scheduler, the eligibility engine and the review loop work. Uploading your own material, the mock engine and the planning tools do not yet. We would rather tell you that than take your money for a promise.
