What is new
A new icon, a real settings page and a popup, one-click pairing with the app (no code to copy), install buttons in the app for Chrome, Edge and Brave, and automatic refresh of the helper folder after each app update.

Install it in four steps
- Extract the zip. You get a folder called Study-with-Sarang-Helper.
- Open
chrome://extensions(Edge:edge://extensions, Brave:brave://extensions) and switch on Developer mode. - Choose Load unpacked and pick the extracted folder.
- In the app open Settings, Drift detection, Browser helper, press Pair the extension, then press Connect to the app on the helper's page. No code to copy.
The desktop app can do the first steps for you: its Install the helper buttons open the right extensions page and copy the folder path. Chrome and Edge do not allow a program to install an extension silently from outside their stores, so Load unpacked stays your click. After that, the app keeps the folder current with each update.
Windows may ask you to confirm once
The installers are signed with a self-made certificate, not a paid one, so Windows SmartScreen can show "Windows protected your PC". Choose More info, then Run anyway. Compare the SHA-256 above with the file if you want to be sure it is untouched. macOS and Android versions are not available yet; the web versions work on any device.
What the apps send
The desktop apps work offline and send nothing about you. They contact this website only to look for a newer version. The web versions use Vercel Web Analytics and Speed Insights to count visits and measure speed, without cookies; each app has a switch to turn it off.
