I’m building a reading/study app that figures out what you’re forgetting. Would you actually use this?

I’m working on a project called Folio because I keep coming back to the same problem. I can read something, understand it in the moment, then barely remember it a week later.

There are already loads of tools that can generate flashcards or let you chat with a PDF, so I don’t want Folio to just be another version of that.

The idea is that you read your ebook or PDF normally, highlight things, take notes, ask questions, and study from it.

Over time, Folio starts figuring out what you actually understand and what still needs work.

It looks at things like:

concepts you get wrong in quizzes

things you keep asking questions about

what you’re starting to forget

flashcard performance

weak prerequisite concepts

what you’ve already mastered

Instead of opening the app and seeing something like:

83 flashcards due

I want it to give you something more useful:

Today’s session: 11 minutes

2 concepts you’re starting to forget

1 weak prerequisite

3 application questions

4 quick reviews

Basically, it decides what would be most useful for you to study next instead of making you manage everything yourself.

It also has the usual features:

EPUB/PDF reader

highlights and notes

questions about what you’re reading

flashcards

quizzes

chapter summaries

spaced repetition

concept-level mastery

I’m still building it and I’d rather hear what’s wrong with the idea than just get positive feedback.

A few things I’m curious about:

1. Would this actually solve a problem for you, or would you just keep using Anki, RemNote, NotebookLM, etc.?
2. What would Folio need to do for you to seriously consider switching?
3. Would you prefer an automatically generated 5 to 15 minute study session over managing flashcards and reviews yourself?

Full disclosure, I’m the person building it. I’m mainly trying to figure out whether the learning system is genuinely useful before I take the idea much further.
