What happens
when you snap.
Snap mode is the part of Solvecoon with the strongest privacy claim, so it is worth being precise about the mechanics rather than saying private and moving on. Here is the actual sequence, in order.

How it works
You press the shortcut
Cmd/Ctrl + Shift + S. A content script draws the overlay. Nothing has been captured.
You drag a box
The visible tab is captured, then cropped to your rectangle on your own machine and compressed to WebP.
Only the crop is sent
The crop goes to the backend, which streams the answer back. The rest of the capture never leaves.
What it handles
Local cropping
The crop happens in the browser, before any upload.
Region only
What is outside your rectangle is discarded in memory, not sent.
Never retention
Screenshots are not stored by default. Saving them is a setting you enable.
Compressed
WebP keeps the upload small, which is why the answer starts fast.
Streamed answers
Text arrives as it is generated, then one validated result at the end.
Works on anything rendered
HTML, PDF, canvas, video frames, images.
A real one, worked out
This is the shape of every answer: the result first, then the reasoning that got there.
Question
A capture of a velocity-time graph: find the distance travelled in the first 6 seconds.
Answer
45 metres
Steps
- 1Distance is the area under a velocity-time graph.
- 2From the capture, the graph rises from 0 to 10 m/s over the first 3 seconds.
- 3That is a triangle: area = (1/2)(3)(10) = 15 m.
- 4It then holds 10 m/s for the next 3 seconds.
- 5That is a rectangle: area = 3 x 10 = 30 m.
- 6Total distance = 15 + 30 = 45 m.
Snap the axes with the curve. Without the axis units the shape is meaningless and any number is a guess.

I only ever see the box you drew. Everything else stays yours.
What it will not do
- It will not capture anything outside the visible tab, including other windows or your desktop.
- It will not capture until you drag. Pressing the shortcut alone sends nothing.
- It will not retain the image unless you opt in.
- It will not be used in exams or on proctored assessments.
Solvecoon is a study aid, not an answer machine. Exams, graded quizzes, and proctored tests are off limits — see the acceptable use policy.
Questions people ask
- Can it see my other tabs or windows?
- No. The capture is of the visible area of the tab you are on, and only the rectangle you drag is used.
- Is the screenshot stored?
- Not by default. Retention is set to Never, meaning the crop is used to produce the answer and then dropped. You can opt into saving screenshots with your history.
- Why WebP?
- It keeps the upload small enough that the answer starts streaming quickly, without losing the detail needed to read text.
- Does it work on video?
- On a paused frame, yes. The capture reads whatever pixels the tab is showing.
