The Junk Drawer

The Junk Drawer is four study tools in one app. Open the drawer, take what you need.

STUDY SPACE

Paste your notes, scan a handout, import a PDF, or record a lecture. Study Space reads your material and builds a 3D study room from it - every concept, definition and formula you actually have to know, laid out as a place you can move through instead of a list you scroll.

Then it generates practice from the same material. Not a fixed stack of flashcards: the questions rebuild themselves every time you sit down, so one set of notes becomes thousands of distinct questions. That happens on your device, offline, forever, at no extra cost.

Spaced repetition decides what comes back and when, so you spend your time on what you are about to forget. Typed answers are graded generously - a near miss is not marked wrong. And a wrong answer tells you which mistake you made rather than just turning red.

CITATION GENERATOR

Paste a link or a DOI, or search for a source by name. Get it in APA 7, MLA 9, Chicago 17 (author-date or notes), or Harvard.

Most citations are free, and they are free because they run on your device - the app reads the publisher's own record directly, so your reading list never reaches a server. AI is only involved when a detail is genuinely missing from the source, and that is the only time a citation costs anything.

Every field shows where it came from. A citation is marked verified only when every part of it came from the source itself - never when something was filled in for you.

GRADE FORECASTER

Enter your categories and their weights and find out what you need on everything that is left. It handles weighted categories, dropped lowest scores, and as many courses as you take, then tells you where your GPA lands. On your device, free.

QUOTE FORMATTER

Save the things people actually say, formatted and attributed properly, with the date and the context attached. On your device, free.

HOW PAYING WORKS

Everything above is free and unlimited except the two things that call an AI model and cost real money to run: generating a Study Space, and asking AI to find a citation's missing details. Those spend tokens.

Buy tokens outright and they never expire, or subscribe for a monthly allowance. Either way you are paying for the generation, not for access - once a Study Space exists it practices forever, offline, without spending anything again.

No ads. No selling your data. Your notes are yours.
