A study tool for PDFs
Drop in a PDF, select the parts that matter, and pick how you want to think about them — Outline, Cornell, Boxing, Question & Answer, or Slip-box. Your notes build themselves as you read.
The sun heats oceans, lakes, and rivers, causing evaporation, where liquid water turns to vapor. As it cools, it undergoes condensation, forming clouds, which release water back to the surface as precipitation.
How it works
A textbook chapter, a paper, a slide deck exported as a PDF — it opens straight into the reading pane, no upload wait, no conversion.
Select any passage and highlight it. Each highlight turns into an editable note in the panel beside it, in real time.
Switch between five note-taking structures whenever you like. What you see is what exports — never the raw PDF text.
One highlight, five structures
This is the water cycle passage from the preview above, run through each method. Try a tab — the notes on the right are what StudyEaseHaven would actually generate.
The PDF, highlighted
Water moves through the environment in a continuous cycle. The sun heats oceans, lakes, and rivers, causing evaporation, where liquid water turns into vapor and rises into the atmosphere. As this vapor cools at higher altitudes, it undergoes condensation, forming clouds. When droplets grow heavy enough, precipitation returns the water to the surface as rain, snow, or hail. Some is absorbed into the ground through infiltration, replenishing aquifers, while the rest flows across land as runoff, eventually returning to the sea to begin again.
Along the way
Study in focused sprints without leaving the page — start a timer, take your break, and pick up right where you left off.
A highlight is a starting point, not the final word — rewrite any note in your own language before it's exported.
Every note remembers which page it came from, so you can trace any idea back to the source in one click.
No save button to remember — your highlights and edits are kept automatically while you read.
Switch to a low-light theme for late-night reading — easier on the eyes, same highlighting and notes underneath.
Download or copy your finished notes — never the raw PDF text, just the thinking you did on top of it.
Open a PDF and watch your first highlight become a note.
