Use AI to turn your notes into questions, test yourself with the notes closed, and track what still needs work.
Core workflow
Take taught material, test it properly, and bring the weak parts back before they fade.
Use the material you were actually taught instead of building a revision system from a blank page.
One taught idea can become short questions, answers, definitions, and other ways of testing the same memory.
Type the answer with the notes closed, then use AI marking, hints, and explanations without leaving the topic.
If something breaks today, it comes back sooner. If it holds, it waits until it is genuinely due again.
Recall tracking shows which cards are holding, overdue, or starting to fade.
The revision job stays the same whether the source material is biology, history, medicine, or another taught subject.
Recall tracking
A progress view only matters if it shows what is likely to fail next, not just what you opened today.

The same taught material moves through cleanup, question building, answer checking, explanations, and return timing.
Capture the source material first, then use AI to clean it into something you can actually work with.
Import them into the same study system instead of rebuilding everything from scratch.

From the founder
Custom Backup is built for the job that starts after class: turn your own notes into questions, answer them cold, and keep weak material coming back until it holds.
Built by a Year 13 student who wanted a revision system that measured memory, not just activity.
School review
An early outside response came after the product and resources were reviewed at Caroline Chisholm School.
"Custom Backup is a revision support tool created by a Year 13 student. Feel free to scan the QR code and check the resources out."

In practice
Less passive revision. A clearer picture of what will still be there tomorrow.
You stop mistaking familiarity for memory because the system keeps asking for the answer cold.
The cards that are slipping show up before exam week turns them into a surprise.
Notes, questions, answers, and review timing sit in the same system instead of five separate tools.
AI hints, marking, and explanations stay attached to the card that failed, where they are actually useful.
The public library covers retrieval, spacing, flashcard structure, and how the product works without signup.
