Welcome to documents
that answer back.
StudyAI turns a PDF, a lecture deck or a Word file into a workspace you can actually work in — the page open beside a canvas you can draw on, notes that stay with it, tasks that know their deadline, and an AI that actually read the thing and can show you where.

Worked examples
One upload. A whole desk. Reader, canvas, notes, planner and AI — open at once, around one file.
The page, where you left it. Open the file and it stays open — the same page, the same scroll, next time you come back. Float it over the canvas when you need the room.
- PDF, Word and PowerPoint, rendered in the browser
- Page rail for the thing you half-remember seeing
- Minimise to a floating window instead of closing it
Chapter 4 · Transport across membranes
Drop the file. Walk away. One upload starts two jobs: one builds the workspace, the other reads the document. Neither needs you.
Both tracks report where they got to, and they fail separately — so a board that built fine never hides a reading that did not, and you always know which half to retry.
It read the thing. Not the filename. Not the first page. The whole document, before you asked it anything.
Most tools stuff your PDF into a prompt and hope. This one pulls the document apart first — what it is, what it covers, how it is laid out, and where every passage sits — and keeps all of it. Every answer you get later is built out of that, which is why it can always tell you the page if you ask for it.
It knows its real name.
You called it bio-ch4-final-v2.pdf. It is called Cell Structure and Function, and that is the name it uses when it tells you where an answer came from.
It knows the subject.
Biology, not “document 4”. Which is how it tells three chapter fours apart when you ask across everything.
It maps the outline.
Chapters and sections with the pages they run over — so “the bit about transport” is a place, not a search.
It cuts on meaning.
Passages span page breaks, because paragraphs do. A thought that starts on 4 and ends on 5 stays one thought.
It searches the lot.
One question can go across every document you have ever uploaded, and come back knowing which one answered.
It never answers from memory. Every reply is searched out of your pages first. The receipts are a switch — off while you read, on when you check.
Turn citations on and every claim is a link. It opens the document panel at exactly the passage the answer came from — same tab, same scroll position, no hunting for it.
The answer
Water moves into the cell and pressure builds against the membrane until it ruptures.
Page 12, opened
This part never switches off. Search the passages, read the pages around the hit, search again if the first came back thin. It happens on every answer, cited or not — the citations are the display, never the grounding.

upload and it is running
The hundred small things. The ones you never notice until you use something that got them wrong.
Folders that nest
A real tree, not a flat list with tags bolted on. Term, module, week — however you already think about it.
Search everything at once
One box over every folder, document, note and task you own. It opens with results already in it.
Float the document
Minimise the page into a window that hovers over the canvas, so the board gets the full width and the figure stays visible.
The split remembers you
Drag the divider once. Every document you open sits where you left it, from the very first paint.
A calendar that counts
Tasks land on days, days get dots, and the month tells you where the week is going before you open it.
Share a read-only link
Send someone the document without sending them the file, or your notes, or your account.
Locked by default
Documents and folders start private. Nothing is shared because you forgot to check a box.
Light and dark, properly
Not a filter over a light theme. Both are designed, and the app follows your system unless you say otherwise.
Built to be lived in
Square edges, dense type, no animation that makes you wait. It is a tool you have open for four hours, not a demo.
Pay for what you put through it. Your notes, boards and todos are unlimited on every plan, free included. Credits are only spent when a model does the work.
