The workflow
The workflow,
start to finish.
Snapping a question sounds trivial and mostly is, but the difference between a good answer and a confidently wrong one is usually the box you dragged. This page is the whole routine: what to include, what to check, and what happens to the image.

How it works
Get the whole question in view
Scroll so the stem, the data, and the diagram are all on screen at once. The capture cannot see what is scrolled away.
Drag wider than feels necessary
Include units, axis labels, table headers, and any given conditions above the question.
Read the steps against your attempt
Do not read for the answer. Read for the first line where your working and its working differ.
What it handles
What to include
The question, the data it references, the diagram, and any instruction line that changes the task.
What to leave out
Other questions. Two questions in one capture usually means one answer to the wrong one.
When to select instead
If the text is real selectable text, highlighting it is faster and more accurate than a capture.
When the answer looks wrong
Check the crop first. A cut-off exponent or a missing minus sign explains most bad answers.
What gets uploaded
Only your rectangle, cropped locally and compressed, then discarded after the answer.
Where it ends up
In the side panel and in your history, which is seven days on free and unlimited on Pro.
A real one, worked out
This is the shape of every answer: the result first, then the reasoning that got there.
Question
3 mol of H2 reacts with 2 mol of N2 to make ammonia. Which reactant is limiting? (N2 + 3H2 -> 2NH3)
Answer
Hydrogen is limiting
Steps
- 1Read the balanced equation from the capture: 1 N2 reacts with 3 H2.
- 2Ask what 2 mol of N2 would need: 2 x 3 = 6 mol of H2.
- 3Only 3 mol of H2 is available, which is less than 6.
- 4So hydrogen runs out first and is the limiting reactant.
- 5Cross-check from the other side: 3 mol of H2 needs only 1 mol of N2, and 2 mol is available. Nitrogen is in excess.
This is why the capture has to include the balanced equation. Crop it out and the mole ratio is unknowable, and the answer becomes a guess.

Nine out of ten wrong answers are a cropping problem. Drag wider.
What it will not do
- It will not see anything outside the rectangle you dragged, including the line just above it.
- It will not read text that is scrolled off the visible tab.
- It will not be used on graded quizzes, tests, or proctored exams.
- It will not save the image unless you switch screenshot saving on.

Questions people ask
- What is the single most common mistake?
- Cropping too tight. The mole ratio, the axis units, the exponent, or the word not in the stem gets left outside the box, and the answer is confidently wrong.
- Should I snap or select?
- Select when the text is real text: it is faster and there is nothing to misread. Snap for images, PDFs, diagrams, handwriting, and apps that block selection.
- Can I snap several questions at once?
- You can, but do not. One capture, one question. Batched captures produce answers to the question in the middle.
- Does the image leave my computer?
- The cropped region does, because that is what gets read. The rest of the screenshot never leaves the browser, and the crop is discarded after the answer unless you opted into saving it.
