Clued InDrop in your notes
A PDF, photos of your notebook or pasted text. Clued In reads it once and splits it into units, each with the facts you'll be asked about.
Case file · iPhone
Your notes just became a detective case.
Clued In turns your lecture notes into a mystery. Every clue is locked behind a question about what you studied. To catch the mastermind, you have to actually learn it.

how it works
From a PDF to a whodunit in about a minute.
You bring the notes. Clued In writes the case around them.
Crack the locks
Each unit is a chapter with six clues. To open one you answer exam-style questions written from your notes. Every question cites the line it came from.
Catch the mastermind
Every clue you open reveals evidence: who, where, how. Rule suspects out yourself and accuse when you're sure. Accusing early is worth more.
what's inside
Built to make you study, not just scroll.
Questions like the exam
Multiple choice, matching, timelines, name the term, explain it in your own words. The hard kind: concepts you mix up, conditions that must all hold.
Every answer cites your notes
Miss one and you see the right answer next to the exact sentence from your document. No mystery about where it came from.
Cold Cases
Questions you got wrong come back on a spaced schedule until they stick. Your daily review, disguised as unfinished business.
You do the deducing
One mystery per notebook, set in your subject. The app never crosses a suspect out for you. Your board, your notes, your accusation.
Rank up
Rookie to Commissioner. A detective badge with your solved cases, accuracy and streak, ready to share.
Your file stays on your phone
The original PDF never leaves your iPhone. Only its text is sent, once, to build your plan, and the app asks you first.
The Mastermind
One mystery per notebook, written for your subject.
Cell biology? The missing lab culture. Constitutional law? The forged ruling. Up to six suspects with visible traits, a handful of hideouts and methods, and the decisive piece of evidence waits in your last chapter. You can't skip to the ending.

questions
Before you open the case.
What kind of notes work?
Typed PDFs, scanned pages, photos of a handwritten notebook (read on your phone) or pasted text. Any language: the questions come out in the language of your notes. The mystery and the interface are in English for now.
Does an AI read my notes?
Yes. The study plan, the mystery and the questions are written by Claude, a model made by Anthropic. The app asks before anything is sent. Only the text of your document goes, never your name or email, and under Anthropic's commercial terms it isn't used to train models.
Can a question be wrong?
Questions are generated from your notes and each one cites its source line, so you can check it in a tap. Clued In is a study aid alongside your course material, not a replacement for it.
Is there a free trial?
No trial, but the first step is free: upload a document and see your whole plan, with its mystery and suspects, before you pay anything.
How do I cancel?
In your iPhone's Settings › Apple Account › Subscriptions, or from the app in Me › Settings › Manage subscription. You keep access until the end of the period you paid for.
How do I delete my account?
Me › Settings › Delete account. It removes your account, notebooks and progress from our server right away. Deleting the app removes everything stored on your phone.
