Qind for students
Keep every note, PDF and article findable
Lecture notes, readings and half-read articles end up in five different places. Save them to one library instead, then ask a question and get an answer with a link to the note it came from.
Free plan, no time limit. No card needed.
In your library

What's the difference between a Type I and a Type II error?
A Type I error is rejecting a null hypothesis that is actually true: a false positive 1 . A Type II error is keeping one that is false: a false negative 2 . Your lecture notes add that a lower significance level makes Type I errors rarer and Type II errors more likely 1 .

Where things get lost today
Notes in five places
Lecture notes in one app, slides in the course portal, readings as PDFs in Downloads, articles in browser tabs. The material exists. You just can't put your hand on it.
Revision week starts with searching
Twelve weeks of material, one exam, and the first evening goes on finding the slide where the professor explained regression.
Which source said that?
Writing an essay means rereading readings you have already read, because you can't remember which one made the point you want to cite.
Course material that disappears
Course pages close after the term and shared folders get archived. Notes you need next year are gone by the summer.
How it works for students
-
Save as you go
After a lecture, save your notes and the slides. When you read something useful for an essay, clip it in your browser.
-
Qind reads it
Every item gets a summary and becomes searchable by what it means, not only by the words in it.
-
Ask before the exam
Ask in plain language and check the answer against the notes it links to.
What you get
-
One library for every course
Save lecture notes, slides and PDFs, clip articles with the web clipper, and add photos of handouts. It all sits in one place you can search.
-
Ask your own material
Ask "What are the three causes of the French Revolution in my history notes?" and get an answer drawn from what you saved, with links to each source.
-
A summary of every item
Qind writes a short summary of each reading and set of slides, so you can see what a 40-page PDF covers before you open it.
-
Collections per course
Keep a collection for each module. The Free plan has three; on Basic and Pro, new saves are also tagged and filed for you.
A library that lasts longer than the term
A single semester brings hundreds of slides, readings and pages of notes. Most of it is useful again later: in revision week, in the essay due next month, in next year’s module that builds on this one. The hard part is getting back to it.
Qind is a place to keep all of it. You save notes, slides, PDFs and articles as you go. Qind writes a short summary of each one, so a long reading is easy to recognize later. When you need something, you ask: “Explain the difference between Type I and Type II errors from my statistics notes.” Qind answers from what you saved and lists the notes and readings it used, so you can open them and check.
That last part matters for coursework. An answer is only useful if you can trace it back to the lecture or reading it came from, and cite that source properly in your essay.
The library also carries over. First-year statistics notes are still there when you need them for your dissertation’s methods chapter, long after the course page has closed.
You can start on the Free plan: AI summaries, the web clipper and Ask Qind, with no card needed. That is enough to run one module through Qind and see whether it changes how you revise.
